Documentation: genpt: Don't use code block marker before iommu_amdv1.c include listing
Stephen Rothwell reports htmldocs warning when merging iommu tree:
Documentation/driver-api/generic_pt.rst:32: WARNING: Literal block expected; none found. [docutils]
This is because of duplicate double colon code block markers: one after
generic_pt/fmt/iommu_amdv1.c and the one in its preceding paragraph. The
resulting htmldocs, however, only marks the include listing (after the
former) up as it should be.
Drop the latter to fix the warning.

PCI/TSM: Establish Secure Sessions and Link Encryption
The PCIe 7.0 specification, section 11, defines the Trusted Execution
Environment (TEE) Device Interface Security Protocol (TDISP). This
protocol definition builds upon Component Measurement and Authentication
(CMA), and link Integrity and Data Encryption (IDE). It adds support for
assigning devices (PCI physical or virtual function) to a confidential VM
such that the assigned device is enabled to access guest private memory
protected by technologies like Intel TDX, AMD SEV-SNP, RISCV COVE, or ARM
CCA.
The "TSM" (TEE Security Manager) is a concept in the TDISP specification
of an agent that mediates between a "DSM" (Device Security Manager) and
system software in both a VMM and a confidential VM. A VMM uses TSM ABIs
to setup link security and assign devices. A confidential VM uses TSM
ABIs to transition an assigned device into the TDISP "RUN" state and
validate its configuration. From a Linux perspective the TSM abstracts
many of the details of TDISP, IDE, and CMA. Some of those details leak
through at times, but for the most part TDISP is an internal
implementation detail of the TSM.
CONFIG_PCI_TSM adds an "authenticated" attribute and "tsm/" subdirectory
to pci-sysfs. Consider that the TSM driver may itself be a PCI driver.
Userspace can watch for the arrival of a "TSM" device,
/sys/class/tsm/tsm0/uevent KOBJ_CHANGE, to know when the PCI core has
initialized TSM services.
The operations that can be executed against a PCI device are split into
two mutually exclusive operation sets, "Link" and "Security" (struct
pci_tsm_{link,security}_ops). The "Link" operations manage physical link
security properties and communication with the device's Device Security
Manager firmware. These are the host side operations in TDISP. The
"Security" operations coordinate the security state of the assigned
virtual device (TDI). These are the guest side operations in TDISP.
Only "link" (Secure Session and physical Link Encryption) operations are
defined at this stage. There are placeholders for the device security
(Trusted Computing Base entry / exit) operations.
The locking allows for multiple devices to be executing commands
simultaneously, one outstanding command per-device and an rwsem
synchronizes the implementation relative to TSM registration/unregistration
events.
Thanks to Wu Hao for his work on an early draft of this support.

dpll: add phase-adjust-gran pin attribute
Phase-adjust values are currently limited by a min-max range. Some hardware requires, for certain pin types, that values be multiples of a specific granularity, as in the zl3073x driver. Add a `phase-adjust-gran` pin attribute and an appropriate field in dpll_pin_properties. If set by the driver, use its value to validate user-provided phase-adjust values.

Merge tag 'pci-v6.18-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
take config space accessor functions.
Implement pci_find_capability(), pci_find_ext_capability(), and
dwc, dwc endpoint, and cadence capability search interfaces with
them (Hans Zhang)
- Leave parent unit address 0 in 'interrupt-map' so that when we
build devicetree nodes to describe PCI functions that contain
multiple peripherals, we can build this property even when
interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)
- Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
Request Size to 128B to avoid a performance issue (Ilpo Järvinen)
- Add sysfs 'serial_number' file to expose the Device Serial Number
(Matthew Wood)
- Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)
Resource management:
- Align m68k pcibios_enable_device() with other arches (Ilpo
Järvinen)
- Remove sparc pcibios_enable_device() implementations that don't do
anything beyond what pci_enable_resources() does (Ilpo Järvinen)
- Remove mips pcibios_enable_resources() and use
pci_enable_resources() instead (Ilpo Järvinen)
- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:
- Leave non-claimed bridge windows disabled
- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices
- Preserve bridge window type when releasing the resource, since
the type is needed for reassignment
- Consolidate selection of bridge windows into two new
interfaces, pbus_select_window() and
pbus_select_window_for_type(), so this is done consistently
- Compute bridge window start and end earlier to avoid logging
stale information
MSI:
- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)
Error handling:
- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)
- If error recovery fails, emit FAILED_RECOVERY uevents for the
devices, not for the bridge leading to them.
This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)
- Align AER with EEH by calling err_handler.error_detected()
callbacks to notify drivers if error recovery fails (Lukas Wunner)
- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback.
This is earlier than before the err_handler.resume() callback
(Lukas Wunner)
- Emit a BEGIN_RECOVERY uevent when driver's
err_handler.error_detected() requests a reset, as well as when it
says recovery is complete or can be done without a reset (Niklas
Schnelle)
- Align s390 with AER and EEH by emitting uevents during error
recovery (Niklas Schnelle)
- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
result of err_handler.error_detected() (Niklas Schnelle)
- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
error information identifies a device without an AER Capability
(Breno Leitao)
- Update error decoding and TLP Log printing for new errors in
current PCIe base spec (Lukas Wunner)
- Update error recovery documentation to match the current code
and use consistent nomenclature (Lukas Wunner)
ASPM:
- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM
This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)
- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)
Power management:
- If a device has already been disconnected, e.g., by a hotplug
removal, don't bother trying to resume it to D0 when detaching the
driver.
This avoids annoying "Unable to change power state from D3cold to
D0" messages (Mario Limonciello)
- Ensure devices are powered up before config reads for
'max_link_width', 'current_link_speed', 'current_link_width',
'secondary_bus_number', and 'subordinate_bus_number' sysfs files.
This prevents using invalid data (~0) in drivers or lspci and,
depending on how the PCIe controller reports errors, may avoid
error interrupts or crashes (Brian Norris)
Virtualization:
- Add rescan/remove locking when enabling/disabling SR-IOV, which
avoids list corruption on s390, where disabling SR-IOV also
generates hotplug events (Niklas Schnelle)
Peer-to-peer DMA:
- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)
Endpoint framework:
- Document sysfs interface for BAR assignment of vNTB endpoint
functions (Jerome Brunet)
- Fix array underflow in endpoint BAR test case (Dan Carpenter)
- Skip endpoint IRQ test if the IRQ is out of range to avoid false
errors (Christian Bruel)
- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)
- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)
- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)
- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)
- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)
- Handle errors in tegra194 BPMP transactions so we don't mistakenly
skip future PERST# assertion (Vidya Sagar)
AMD MDB PCIe controller driver:
- Update DT binding example to separate PERST# to a Root Port stanza
to make multiple Root Ports possible in the future (Sai Krishna
Musham)
- Add driver support for PERST# being described in a Root Port
stanza, falling back to the host bridge if not found there (Sai
Krishna Musham)
Freescale i.MX6 PCIe controller driver:
- Enable the 3.3V Vaux supply if available so devices can request
wakeup with either Beacon or WAKE# (Richard Zhu)
MediaTek PCIe Gen3 controller driver:
- Add optional sys clock ready time setting to avoid sys_clk_rdy
signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)
- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)
NVIDIA Tegra PCIe controller driver:
- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)
- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
Qualcomm PCIe controller driver:
- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)
- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused
probe failures (Krishna Chaitanya Chundru)
- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)
- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root
Port node or the host bridge node (Manivannan Sadhasivam)
- Fetch and map the ELBI register space in the DWC core rather than
in each driver individually (Krishna Chaitanya Chundru)
- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
Shift Feature' and use this in the qcom driver (Krishna Chaitanya
Chundru)
- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)
- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)
Renesas R-Car PCIe controller driver:
- Fix a typo that prevented correct PHY initialization (Marek Vasut)
- Add a missing 1ms delay after PWR reset assertion as required by
the V4H manual (Marek Vasut)
- Assure reset has completed before DBI access to avoid SError (Marek
Vasut)
- Fix inverted PHY initialization check, which sometimes led to
timeouts and failure to start the controller (Marek Vasut)
- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain()
(Claudiu Beznea)
- Drop the spinlock protecting the PMSR register - it's no longer
required since pci_lock already serializes accesses (Marek Vasut)
- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
SOPHGO PCIe controller driver:
- Check for existence of struct cdns_pcie.ops before using it to
allow Cadence drivers that don't need to supply ops (Chen Wang)
- Add DT binding and driver for the SOPHGO SG2042 PCIe controller
(Chen Wang)
STMicroelectronics STM32MP25 PCIe controller driver:
- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)
- Add pinctrl_pm_select_init_state() for use by stm32 driver, which
needs it during resume (Christian Bruel)
- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)
Synopsys DesignWare PCIe controller driver:
- Add support for x16 in devicetree 'num-lanes' property (Konrad
Dybcio)
- Verify that if DT specifies a single IRQ for all eDMA channels, it
is named 'dma' (Niklas Cassel)
TI J721E PCIe driver:
- Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
Vadapalli)
- Power controller off before configuring the glue layer so the
controller latches the correct values on power-on (Siddharth
Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)
- Add Peripheral Virtualization Unit (PVU), which restricts DMA from
PCIe devices to specific regions of host memory, to the ti,am65
binding (Jan Kiszka)
Xilinx NWL PCIe controller driver:
- Clear bootloader E_ECAM_CONTROL before merging in the new driver
value to avoid writing invalid values (Jani Nurminen)"

It has been a relatively busy cycle in docsland, with changes all over:
- Bring the kernel memory-model docs into the Sphinx build in the "literal
include" mode.
- Lots of build-infrastructure work, further cleaning up long-term
kernel-doc technical debt. The sphinx-pre-install tool has been
converted to Python and updated for current systems.
- A new tool to detect when documents have been moved and generate HTML
redirects; this can be used on kernel.org (or any other site hosting the
rendered docs) to avoid breaking links.
- Automated processing of the YAML files describing the netlink protocol.
- A significant update of the maintainer's PGP guide.
...and a seemingly endless series of typo fixes, build-problem fixes, etc.

Networking changes for 6.18.
Core & protocols
----------------
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets
and the backlog, almost doubling the Pps capacity under DoS.
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance by
an additional 50%, even more under extreme conditions.
- Add support for PSP encryption of TCP connections; this mechanism has
some similarities with IPsec and TLS, but offers superior HW offloads
capabilities.
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than
one congestion notification signal per RTT and is a building block for
Low Latency, Low Loss, and Scalable Throughput (L4S).
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath.
- Refactor skb deferral free to better scale on large multi-NUMA hosts,
this improves TCP and UDP RX performances significantly on such HW.
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds.
- Improve handling of setups with a large number of nexthop, making dump
operating scaling linearly and avoiding unneeded synchronize_rcu() on
delete.
- Improve bridge handling of VLAN FDB, storing a single entry per bridge
instead of one entry per port; this makes the dump order of magnitude
faster on large switches.
- Restore IP ID correctly for encapsulated packets at GSO segmentation
time, allowing GRO to merge packets in more scenarios.
- Improve netfilter matching performance on large sets.
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting recent
TCP autotuning changes.
- Allow bridges to redirect to a backup port when the bridge port is
administratively down.
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups.
- Add RCU safety to dst->dev, closing a lot of possible races.
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing
code duplication.
- Supports pulling data from an skb frag into the linear area of an XDP
buffer.
Things we sprinkled into general kernel code
--------------------------------------------
- Generate netlink documentation from YAML using an integrated
YAML parser.
Driver API
----------
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection.
- Introduce API for fetching the DMA device for a given queue, allowing
TCP zerocopy RX on more H/W setups.
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath.
- Add a new dedicated ethtool callback enabling drivers to provide the
number of RX rings directly, improving efficiency and clarity in RX
ring queries and RSS configuration.
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause.
- Support for DPLL phase offset exponential moving average, controlling
the average smoothing factor.
Device drivers

- Macsec:
- replace custom netlink attribute checks with policy-level checks
- Bonding:
- support aggregator selection based on port priority
- Microsoft vNIC:
- use page pool fragments for RX buffers instead of full pages to
improve memory efficiency

Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication
- Supports pulling data from an skb frag into the linear area of an
XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML
parser
Driver API:

easily building DevMem-enabled drivers with a unified XDP/skbs
datapath
- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause
- Support for DPLL phase offset exponential moving average,
controlling the average smoothing factor

Pin control changes for the v6.18 kernel cycle:
Core changes:
- Allow pins to be identified/marked as GPIO mode with
a special callback. The pin controller core is now
"aware" if a pin is in GPIO mode if the callback is
implemented in the driver, and can thus be marked
as "strict", i.e. disallowing simultaneous use of a
line as GPIO and another function such as I2C. This
is enabled in the Qualcomm TLMM driver and also
implemeted from day 1 in the new Broadcom STB driver.
- Rename the pin config option PIN_CONFIG_OUTPUT to
PIN_CONFIG_LEVEL to better describe what the config is
doing, as well as making it more intuitive what shall
be returned when reading this property.
New drivers:
- Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver.
- Qualcomm Glymur family pin controller driver.
- Broadcom STB family pin controller driver.
- Tegra186 pin controller driver.
- AAEON UP pin controller support. This is some special
pin controller that works as an external advanced line
MUX and amplifier for signals from an Intel SoC.
A cooperative effort with the GPIO maintainer was
needed to reach a solution where we reuse code from
the GPIO aggregator/forwarder driver.
- Renesas RZ/T2H and RZ/N2H pin controller support.
- Axis ARTPEC-8 subdriver for the Samsung pin controller
driver.
Improvements:
- Output enable (OEN) support in the Renesas RZG2L driver.
- Properly support bias pull up/down in the pinctrl-single
driver.
- Move over all GPIO portions using generic MMIO GPIO to
the new generic GPIO chip management which has a nice and
separate API.
- Proper DT bindings for some older Broadcom SoCs.
- External GPIO (EGPIO) support in the Qualcomm SM8250.
Deleted code:
- Dropped the now unused Samsung S3C24xx drivers.

pinctrl: generic: rename PIN_CONFIG_OUTPUT to LEVEL
This generic pin config property is confusingly named so let's rename it to make things clearer. There are already drivers in the tree that use PIN_CONFIG_OUTPUT to *read* the value of an output driven pin, which is a big semantic confusion for the head: are we then reading the setting of the output or the actual value/level that is put out on the pin? We already have PIN_CONFIG_OUTPUT_ENABLE that turns on driver buffers for output, so this can by logical conclusion only drive the voltage level if it should be any different. But if we read the pin, are we then reading the *setting* of the output value or the *actual* value we can see on the line? If the pin has not first been set into output mode with PIN_CONFIG_OUTPUT_ENABLE, but is instead in some input mode or tristate, what will reading this property actually return? Reading the current users reading this property it is clear that what we read is the logical level of the pin as 0 or 1 depending on if it is low or high. Rename it to PIN_CONFIG_LEVEL so it is crystal clear that we set or read the voltage level of the pin and nothing else.

docs: initramfs: file data alignment via name padding
The existing cpio extraction logic reads (maximum PATH_MAX) name_len
bytes from the archive into the collected name buffer and ensures that
the trailing byte is a null-terminator. This allows the actual file name
to be shorter than name_len, with the name string simply zero-terminated
prior to the last byte.
Initramfs generators, such as dracut-cpio[1], can take advantage of name
zero-padding to align file data segments within the archive to
filesystem block boundaries. Block boundary alignment may allow the
copy_file_range syscall to reflink archive source and destination
extents.

media: Wrap file->private_data access with a helper function
Accessing file->private_data manually to retrieve the v4l2_fh pointer is error-prone, as the field is a void * and will happily convert implicitly to any pointer type. To avoid direct access to file->private_data, introduce a new inline function that retrieves the v4l2_fh pointer, and use it to replace common access patterns through the kernel. Changes to drivers have been generated with the following coccinelle semantic patch: @@ struct file *filp; identifier fh; @@ - struct v4l2_fh *fh = filp->private_data; + struct v4l2_fh *fh = file_to_v4l2_fh(filp); Manual changes have been applied to Documentation/ to update the usage patterns, and to include/media/v4l2-fh.h to add the new function. While at it, fix a typo in the title of v4l2-fh.rst: the file describes the "file handles" API, not "file handlers". No functional change is intended, this only paves the way to remove direct accesses to file->private_data and make V4L2 drivers safer. Other accesses to the field will be addressed separately.

cxl/region: Add inject and clear poison by region offset
Add CXL region debugfs attributes to inject and clear poison based on an offset into the region. These new interfaces allow users to operate on poison at the region level without needing to resolve Device Physical Addresses (DPA) or target individual memdevs. The implementation uses a new helper, region_offset_to_dpa_result() that applies decoder interleave logic, including XOR-based address decoding when applicable. Note that XOR decodes rely on driver internal xormaps which are not exposed to userspace. So, this support is not only a simplification of poison operations that could be done using existing per memdev operations, but also it enables this functionality for XOR interleaved regions for the first time. New debugfs attributes are added in /sys/kernel/debug/cxl/regionX/: inject_poison and clear_poison. These are only exposed if all memdevs participating in the region support both inject and clear commands, ensuring consistent and reliable behavior across multi-device regions. If tracing is enabled, these operations are logged as cxl_poison events in /sys/kernel/tracing/trace. The ABI documentation warns users of the significant risks that come with using these capabilities. A CXL Maturity Map update shows this user flow is now supported.

It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle for docs, especially the build
system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the
turn of the millennium. Over the following 25 years, it accumulated
a vast amount of cruft, all in a language few people want to deal
with anymore. Mauro's Python replacement in 6.16 faithfully
reproduced all of the cruft in the hope of avoiding regressions.
Now that we have a more reasonable code base, though, we can work
on cleaning it up; many of the changes this time around are toward
that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository
links.
...and lots of fixes and updates"

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc.
- Support DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.

gpio updates for v6.17-rc1
GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose the
global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the existing
interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more users
- start the process of allowing to compile-out the legacy parts of the
GPIO core for users who don't need it by introducing a new Kconfig
option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio helper
out of the core struct gpio_chip into their own structure that wraps
it: create a new header with modern interfaces and convert several
drivers to using it
- remove the platform data structure associated with the gpio-mmio helper
from the kernel after having converted all remaining users to generic
device properties
- remove legacy struct gpio definition as it has no more users
New drivers:
- add the GPIO driver for the Apple System Management Controller
Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value setter
callbacks
- convert gpio-rcar to using simple device power management ops callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already handles
that
- also drop unneeded GPIO range checks in drivers, the core already makes
sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user
wants to change direction of the pin to output even though these
drivers don't need to do anything else to actually set the direction,
otherwise a call like gpiod_direction_output(d, 1) will not result in
the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases where
the GPIO core can already handle their absence
- allow building gpio-palmas as a module
Fixes:
- use correct bit widths (according to the documentation) in gpio-virtio
Device-tree bindings:
- convert several of the legacy .txt documents for many different devices
to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of simple
hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the arguments
in some functions, remove duplicate includes, etc.
- documentation updates

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver (Apple SMC) and extensions to existing drivers
for supporting new HW models. A lot of different impovements across
drivers and in core GPIO code. Details on that are in the signed tag
as usual.
We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them
only for older platforms that still really need them.
Rob Herring has done a lot of work to convert legacy .txt dt-bindings
for GPIO controllers to YAML. There are only a few left now in the
GPIO tree.
A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all
the changes from different trees land in mainline, I'll send you
another PR containing a commit dropping the legacy callbacks from the
tree.
As the quest to pay back technical dept never really ends, we're
starting another set of interface conversions, this time it's about
moving fields specific to only a handful of drivers using the
gpio-mmio helper out of the core gpio_chip structure that every
controller implements and uses. This cycle we introduce a new set of
APIs and convert a few drivers under drivers/gpio/, next cycle we'll
convert remaining modules treewide (in gpio, pinctrl and mfd trees)
and finally remove the old interfaces and move the gpio-mmio fields
into their own structure wrapping gpio_chip.
One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While
it has seen a wide adoption with the help of its user-space
counterpart - libgpiod - there are still users who prefer the
simplicity of sysfs.
As far as the GPIO subsystem is concerned, the problem is not the
existince of the GPIO class as such but rather the fact that it
exposes the global GPIO numbers to the user-space, stopping us from
ever being able to remove the numberspace from the kernel. To that
end, this release we introduced a parallel, limited sysfs interface
that doesn't expose these numbers and only implements a subset of
features that are relevant to the existing users. This is a result of
several discussions over the course of last year and should allow us
to remove the legacy part some time in the future.

Documentation/driver-api/cxl: Introduce conventions.rst
There exists shipping platforms that bend, break, or otherwise lean on ambiguities in the CXL specification. Without driver changes to accommodate these deviations, end users are left without CXL subsystem RAS features. Specifically, provisioning, error translation, and other flows require the CXL subsystem to understand the platforms CXL topology beyond undecorated memory address ranges. Those isolated compatibility problems risk growing into deeper upstream maintenance burden if different platform vendors arrive at diverging solutions. For example, there are multiple options for resolving low-memory-mmio intersecting large-interleave-ways CXL windows. Linux should only entertain one solution to that problem. Now, with the ACPI Specification Working Group, situations like this would be resolved with the "Code First ECN" process to codify Linux expectations in a specification. In the absence of such a process for the CXL specification, create a file in Linux documentation to detail the motivations, assumptions, tradeoffs, and proposals for amending specification language. The goal is to capture the issues such that platform vendors arrive at compatible solutions for these problems and serve as a repository for potential specification updates. The expectation is to update conventions.rst along with CXL subsystem code changes to accommodate the platform topology.

thermal: intel: int340x: Add throttling control interface to PTC
Firmware-based thermal temperature control loops may aggressively throttle performance to prevent temperature overshoots relative to the defined target temperature. This can negatively impact performance. User space may prefer to prioritize performance, even if it results in temperature overshoots with in acceptable range. For example, user space might tolerate temperature overshoots when the device is placed on a desk, as opposed to when it's on a lap. To accommodate such scenarios, an optional attribute is provided to specify a tolerance level for temperature overshoots while maintaining acceptable performance. Attribute: thermal_tolerance: This attribute ranges from 0 to 7, where 0 represents the most aggressive control to avoid any temperature overshoots, and 7 represents a more graceful approach, favoring performance even at the expense of temperature overshoots. Note: This level may not scale linearly. For example, a value of 3 does not necessarily imply a 50% improvement in performance compared to a value of 0.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)
Synopsys DesignWare PCIe controller driver:
- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)
- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)
Device tree bindings:
- Add qcom DT binding for 'global' interrupt (PCIe controller and
link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
Sadhasivam)
- Add qcom DT binding for 8 MSI SPI interrupts for msm8998, ipq8074,
ipq8074-gen3, ipq6018 (Manivannan Sadhasivam)
- Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang)
- Correct indentation and style of examples in brcm,stb-pcie,
cdns,cdns-pcie-ep, intel,keembay-pcie-ep, intel,keembay-pcie,
microchip,pcie-host, rcar-pci-ep, rcar-pci-host, xilinx-versal-cpm
(Krzysztof Kozlowski)
- Convert Marvell EBU (dove, kirkwood, armada-370, armada-xp) and
armada8k from text to schema DT bindings (Rob Herring)
- Remove obsolete .txt DT bindings for content that has been moved to
schemas (Rob Herring)

and IPQ9574 (Varadarajan Narayanan)
- Convert v3,v360epc-pci from text to DT schema binding (Rob Herring)
- Change microchip,pcie-host DT binding to be 'dma-noncoherent' since
PolarFire may be configured that way (Conor Dooley)
Miscellaneous:
- Drop 'pci' suffix from intel_mid_pci.c filename to match similar
files (Andy Shevchenko)
- All platforms with PCI have an MMU, so add PCI Kconfig dependency
on MMU to simplify build testing and avoid inadvertent build
regressions (Arnd Bergmann)
- Update Krzysztof Wilczyński's email address in MAINTAINERS
(Krzysztof Wilczyński)

Restructure the IPMI driver for 6.16
This is a restructure of the IPMI driver, mostly to remove SRCU. The locking had issues, and they were not going to be straightforward to fix. Plus it used tons of memory and was generally a pain. Most of this moves handling of messages out of bh and interrupt context and runs it in thread context. Then getting rid of SRCU is easy. This also has a minor cleanup to remove a warning on newer GCCs and to fix some documentation. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAmg4t4YACgkQYfOMkJGb /4FO9hAAlzLGbSnskRPng8WTMrq9lf2LkpJcJrNrn9Q5eZLlDIYgTHO84fqwQc9e UN4sYHmqAxQgr9SCSU2z8jiMH8vABmuatWTFx7X5oYfBTjmM022cY89gihyDAaeS V3uO7nLJJkkRSGh/Wbpa+XgJfii+27kizy7SB8sySSHU82AJC9Sy7HJeO8H0+tH8 06uKGw/6GgABVoTFCwgOxfibJKE6EZQPHVUD1HmEQBNcLBAruZ0QdQFn3ODZPt/6 qZqzggvB4c7+7xUdPhfXKN3AvGnSkcq9wKzMVO3eiKZx7jFr1a+vqLYFIhnCOJ6l XKGV14XtCL5oI+9DkZcYAd/3NbHbLofzTH8G0TUqNUzZ0hoKq93Hb2y500rZPFzx RhT3BtxzLZQFmDj7mO2Mv+cRCZJ1EOv0nbUI7B7t3tXEzbR6oz3wspUGy1R/g2O4 Cgpg/ePmTWSUYaQbQqlozFdOAB7DdRvoRu6X4YIQW7t6vQhZ8r0ojfKLm1I9FWoH PIl8XZa8jYNZw2N2bneboINSdhcYXOCSZPDLzgTWUqUu83naUPltrTwr8IMLBO8f zvFJda4Z66mDtdon02H0SWq4ihbfb1LZpmL7DsgL09fL2gEnuGjRvalNHDtn1h62 TZ7/vq3U8WoSanT0K9ltH9xBDTpnturpRidssUePm5Xn9sY+fdw= =e8Rg -----END PGP SIGNATURE----- Merge tag 'for-linus-6.16-1' of https://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "Restructure the IPMI driver.

- Add a general sysfs scheme for publishing "Measurement" values
provided by the architecture's TEE Security Manager. Use it to publish
TDX "Runtime Measurement Registers" ("RTMRs") that either maintain a
hash of stored values (similar to a TPM PCR) or provide statically
provisioned data. These measurements are validated by a relying party.
- Reorganize the drivers/virt/coco/ directory for "host" and "guest"
shared infrastructure.
- Fix a configfs-tsm-report unregister bug

gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates

"We have three new drivers, some refactoring in the GPIO core, lots of

will also see these commits coming in from other subsystems as with

A moderately busy cycle for documentation this time around:
- The most significant change is the replacement of the old kernel-doc
script (a monstrous collection of Perl regexes that predates the Git era)
with a Python reimplementation. That, too, is a horrifying collection of
regexes, but in a much cleaner and more maintainable structure that
integrates far better with the Sphinx build system.
This change has been in linux-next for the full 6.15 cycle; the small
number of problems that turned up have been addressed, seemingly to
everybody's satisfaction. The Perl kernel-doc script remains in tree (as
scripts/kernel-doc.pl) and can be used with a command-line option if need
be. Unless some reason to keep it around materializes, it will probably
go away in 6.17.
Credit goes to Mauro Carvalho Chehab for doing all this work.
- Some RTLA documentation updates
- A handful of Chinese translations
- The usual collection of typo fixes, general updates, etc.

tsm-mr: Add TVM Measurement Register support
Introduce new TSM Measurement helper library (tsm-mr) for TVM guest drivers
to expose MRs (Measurement Registers) as sysfs attributes, with Crypto
Agility support.
Add the following new APIs (see include/linux/tsm-mr.h for details):
- tsm_mr_create_attribute_group(): Take on input a `struct
tsm_measurements` instance, which includes one `struct
tsm_measurement_register` per MR with properties like `TSM_MR_F_READABLE`
and `TSM_MR_F_WRITABLE`, to determine the supported operations and create
the sysfs attributes accordingly. On success, return a `struct
attribute_group` instance that will typically be included by the guest
driver into `miscdevice.groups` before calling misc_register().
- tsm_mr_free_attribute_group(): Free the memory allocated to the attrubute
group returned by tsm_mr_create_attribute_group().
tsm_mr_create_attribute_group() creates one attribute for each MR, with
names following this pattern:
MRNAME[:HASH]
- MRNAME - Placeholder for the MR name, as specified by
`tsm_measurement_register.mr_name`.
- :HASH - Optional suffix indicating the hash algorithm associated with
this MR, as specified by `tsm_measurement_register.mr_hash`.
Support Crypto Agility by allowing multiple definitions of the same MR
(i.e., with the same `mr_name`) with distinct HASH algorithms.
NOTE: Crypto Agility, introduced in TPM 2.0, allows new hash algorithms to
be introduced without breaking compatibility with applications using older
algorithms. CC architectures may face the same challenge in the future,
needing new hashes for security while retaining compatibility with older
hashes, hence the need for Crypto Agility.

It has been a reasonably busy cycle for docs...
- Significant changes throughout the tree to bring Python code up to
current standards and raise the minimum Python required to 3.9. Much of
this is preparatory to replacing the ancient Perl scripts/kernel-doc
horror with a slightly less horrifying Python implementation, expected
for 6.16.

tty: tty_driver: document both {,__}tty_alloc_driver() properly
__tty_alloc_driver()'s kernel-doc needed some care: describe the return value using the standard "Returns:", and use the new enum tty_driver_flag for @flags.

cxl/pci: Support Global Persistent Flush (GPF)
Add support for GPF flows. It is found that the CXL specification around this to be a bit too involved from the driver side. And while this should really all handled by the hardware, this patch takes things with a grain of salt. Upon respective port enumeration, both phase timeouts are set to a max of 20 seconds, which is the NMI watchdog default for lockup detection. The premise is that the kernel does not have enough information to set anything better than a max across the board and hope devices finish their GPF flows within the platform energy budget. Timeout detection is based on dirty Shutdown semantics. The driver will mark it as dirty, expecting that the device clear it upon a successful GPF event. The admin may consult the device Health and check the dirty shutdown counter to see if there was a problem with data integrity.

pps: generators: replace copy of pps-gen info struct with const pointer
Some PPS generator drivers may need to retrieve a pointer to their
internal data while executing the PPS generator enable() method.
During the driver registration the pps_gen_device pointer is returned
from the framework, and for that reason, there is difficulty in
getting generator driver data back in the enable function. We won't be
able to use container_of macro as it results in static assert, and we
might end up in using static pointer.
To solve the issue and to get back the generator driver data back, we
should not copy the struct pps_gen_source_info within the struct
pps_gen_device during the registration stage, but simply save the
pointer of the driver one. In this manner, driver may get a pointer
to their internal data as shown below:
struct pps_gen_foo_data_s {
...
struct pps_gen_source_info gen_info;
struct pps_gen_device *pps_gen;
...
};
static int __init pps_gen_foo_init(void)
{
struct pps_gen_foo_data_s *foo;
...
foo->pps_gen = pps_gen_register_source(&foo->gen_info);
...
}
Then, in the enable() method, we can retrieve the pointer to the main
struct by using the code below:
static int pps_gen_foo_enable(struct pps_gen_device *pps_gen, bool enable)
{
struct pps_gen_foo_data_s *foo = container_of(pps_gen->info,
struct pps_gen_foo_data_s, gen_info);
...
}

At the lowest level, the atmel_serial driver is using serial_mctrl_gpio lib to enable/disable the corresponding IRQs accordingly. The warning emitted by CONFIG_DEBUG_ATOMIC_SLEEP is due to disable_irq (called in mctrl_gpio_disable_ms) being possibly called in some atomic context (some tty drivers perform modem lines configuration in regions protected by port lock). Split mctrl_gpio_disable_ms into two differents APIs, a non-blocking one and a blocking one. Replace mctrl_gpio_disable_ms calls with the relevant version depending on whether the call is protected by some port lock.

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

"Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).
To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.
Hence, with this patch, this is what will happen:
echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync
There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.
True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

Driver core changes for 6.13-rc1
Here is a small set of driver core changes for 6.13-rc1.
Nothing major for this merge cycle, except for the 2 simple merge
conflicts are here just to make life interesting.
Included in here are:
- sysfs core changes and preparations for more sysfs api cleanups that
can come through all driver trees after -rc1 is out
- fw_devlink fixes based on many reports and debugging sessions
- list_for_each_reverse() removal, no one was using it!
- last-minute seq_printf() format string bug found and fixed in many
drivers all at once.
- minor bugfixes and changes full details in the shortlog
As mentioned above, there is 2 merge conflicts with your tree, one is
where the file is removed (easy enough to resolve), the second is a
build time error, that has been found in linux-next and the fix can be
seen here:
https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
Other than that, the changes here have been in linux-next with no other
reported issues.

Merge tag 'pci-v6.13-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
callers can't stop a device multiple times, even as we migrate from
the global pci_rescan_remove_lock to finer-grained locking (Keith
Busch)
- Improve pci_walk_bus() implementation by making it recursive and
moving locking up to avoid need for a 'locked' parameter (Keith
Busch)
- Unexport pci_walk_bus_locked(), which is only used internally by
the PCI core (Keith Busch)
- Detect some Thunderbolt chips that are built-in and hence
'trustworthy' by a heuristic since the 'ExternalFacingPort' and
'usb4-host-interface' ACPI properties are not quite enough (Esther
Shimanovich)
Resource management:
- Use PCI bus addresses (not CPU addresses) in 'ranges' properties
when building dynamic DT nodes so systems where PCI and CPU
addresses differ work correctly (Andrea della Porta)
- Tidy resource sizing and assignment with helpers to reduce
redundancy (Ilpo Järvinen)
- Improve pdev_sort_resources() 'bogus alignment' warning to be more
specific (Ilpo Järvinen)
Driver binding:
- Convert driver .remove_new() callbacks to .remove() again to finish
the conversion from returning 'int' to being 'void' (Sergio
Paracuellos)
- Export pcim_request_all_regions(), a managed interface to request
all BARs (Philipp Stanner)
- Replace pcim_iomap_regions_request_all() with
pcim_request_all_regions(), and pcim_iomap_table()[n] with
pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
(Philipp Stanner)
- Remove the now unused pcim_iomap_regions_request_all() (Philipp
Stanner)
- Export pcim_iounmap_region(), a managed interface to unmap and
release a PCI BAR (Philipp Stanner)
- Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
cavium (Philipp Stanner)
Error handling:
- Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
bridge; previously Secondary Bus Reset could only be used when
there was a single device below a bridge (Keith Busch)
- Warn if we reset a running device where the driver didn't register
pci_error_handlers notification callbacks (Keith Busch)
ASPM:
- Disable ASPM L1 before touching L1 PM Substates to follow the spec
closer and avoid a CPU load timeout on some platforms (Ajay
Agarwal)
- Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
as required per spec for all L1 Substates changes (Jian-Hong Pan)
Power management:
- Enable starfive controller runtime PM before probing host bridge
(Mayank Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
Power control:
- Use of_platform_device_create() instead of of_platform_populate()
to create pwrctl platform devices so we can control it based on the
child nodes (Manivannan Sadhasivam)
- Create pwrctrl platform devices only if there's a relevant power
supply property (Manivannan Sadhasivam)
- Add device link from the pwrctl supplier to the PCI dev to ensure
pwrctl drivers are probed before the PCI dev driver; this avoids a
race where pwrctl could change device power state while the PCI
driver was active (Manivannan Sadhasivam)
- Find pwrctl device for removal with of_find_device_by_node()
instead of searching all children of the parent (Manivannan
Sadhasivam)
- Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
('bwctrl') and hotplug files (Bjorn Helgaas)
Bandwidth control:
- Add read/modify/write locking for Link Control 2, which is used to
manage Link speed (Ilpo Järvinen)
- Extract Link Bandwidth Management Status check into
pcie_lbms_seen(), where it can be shared between the bandwidth
controller and quirks that use it to help retrain failed links
(Ilpo Järvinen)
- Re-add Link Bandwidth notification support with updates to address
the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
Järvinen)
- Add pcie_set_target_speed() and related functionality so drivers
can manage PCIe Link speed based on thermal or other constraints
(Ilpo Järvinen)
- Add a thermal cooling driver to throttle PCIe Links via the
existing thermal management framework (Ilpo Järvinen)
- Add a userspace selftest for the PCIe bandwidth controller (Ilpo
Järvinen)
PCI device hotplug:
- Add hotplug controller driver for Marvell OCTEON multi-function
device where function 0 has a management console interface to
enable/disable and provision various personalities for the other
functions (Shijith Thotton)
- Retain a reference to the pci_bus for the lifetime of a pci_slot to
avoid a use-after-free when the thunderbolt driver resets USB4 host
routers on boot, causing hotplug remove/add of downstream docks or
other devices (Lukas Wunner)
- Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
(Guilherme Giacomo Simoes)
- Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)
- Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
detection in cpqphp (Ilpo Järvinen)
- Simplify cpqphp enumeration, which is already simple-minded and
doesn't handle devices below hot-added bridges (Ilpo Järvinen)
Virtualization:
- Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
capability but do isolate functions as though PCI_ACS_RR and
PCI_ACS_CR were set, so the functions can be in independent IOMMU
groups (Mengyuan Lou)
TLP Processing Hints (TPH):
- Add and document TLP Processing Hints (TPH) support so drivers can
enable and disable TPH and the kernel can save/restore TPH
configuration (Wei Huang)
- Add TPH Steering Tag support so drivers can retrieve Steering Tag
values associated with specific CPUs via an ACPI _DSM to improve
performance by directing DMA writes closer to their consumers (Wei
Huang)
Data Object Exchange (DOE):
- Wait up to 1 second for DOE Busy bit to clear before writing a
request to the mailbox to avoid failures if the mailbox is still
busy from a previous transfer (Gregory Price)
Endpoint framework:
- Skip attempts to allocate from endpoint controller memory window if
the requested size is larger than the window (Damien Le Moal)
- Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
handle controller-specific size and alignment constraints, and add
test cases to the endpoint test driver (Damien Le Moal)
- Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
observe DWC-specific alignment requirements (Damien Le Moal)
- Synchronously cancel command handler work in endpoint test before
cleaning up DMA and BARs (Damien Le Moal)
- Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
Cassel)
- Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
(Niklas Cassel)
- Avoid NULL dereference if Modem Host Interface Endpoint lacks
'mmio' DT property (Zhongqiu Han)
- Release PCI domain ID of Endpoint controller parent (not controller
itself) and before unregistering the controller, to avoid
use-after-free (Zijun Hu)
- Clear secondary (not primary) EPC in pci_epc_remove_epf() when
removing the secondary controller associated with an NTB (Zijun Hu)
Cadence PCIe controller driver:
- Lower severity of 'phy-names' message (Bartosz Wawrzyniak)
Freescale i.MX6 PCIe controller driver:
- Fix suspend/resume support on i.MX6QDL, which has a hardware
erratum that prevents use of L2 (Stefan Eichenberger)
Intel VMD host bridge driver:
- Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)
MediaTek PCIe Gen3 controller driver:
- Update mediatek-gen3 DT binding to require the exact number of
clocks for each SoC (Fei Shao)
- Add support for DT 'max-link-speed' and 'num-lanes' properties to
restrict the link speed and width (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add DT and driver support for using either of the two PolarFire
Root Ports (Conor Dooley)
NVIDIA Tegra194 PCIe controller driver:
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
Qualcomm PCIe controller driver:
- Add qcom SAR2130P DT binding with an additional clock (Dmitry
Baryshkov)
- Enable MSI interrupts if 'global' IRQ is supported, since a
previous commit unintentionally masked them (Manivannan Sadhasivam)
- Move endpoint controller cleanups that depend on refclk from the
host to the notifier that tells us the host has deasserted PERST#,
when refclk should be valid (Manivannan Sadhasivam)
- Add DT binding and driver support for IPQ9574, with Synopsys IP
v5.80a and Qcom IP 1.27.0 (devi priya)
- Move the OPP "operating-points-v2" table from the
qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
can be used by other Qcom platforms (Qiang Yu)
- Add 'global' SPI interrupt for events like link-up, link-down to
qcom,pcie-x1e80100 DT binding so we can start enumeration when the
link comes up (Qiang Yu)
- Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
to support this (Qiang Yu)
- Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
'iommu-map' DT property and doesn't need BDF-to-SID translation
(Qiang Yu)
Rockchip PCIe controller driver:
- Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
.align value (Damien Le Moal)
- When unmapping an endpoint window, compute the region index instead
of searching for it, and verify that the address was mapped (Damien
Le Moal)
- When mapping an endpoint window, verify that the address hasn't
been mapped already (Damien Le Moal)
- Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)
- Fix MSI IRQ data mapping to observe the alignment constraint, which
fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
(Damien Le Moal)
- Rename rockchip_pcie_parse_ep_dt() to
rockchip_pcie_ep_get_resources() for consistency with similar DT
interfaces (Damien Le Moal)
- Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
it only in the endpoint start operation (Damien Le Moal)
- Implement pci_epc_ops.stop_link() to disable link training and
controller configuration (Damien Le Moal)
- Attempt link training at 5 GT/s when both partners support it
(Damien Le Moal)
- Add a handler for PERST# signal so we can detect host-initiated
resets and start link training after PERST# is deasserted (Damien
Le Moal)
Synopsys DesignWare PCIe controller driver:
- Clear outbound address on unmap so dw_pcie_find_index() won't match
an ATU index that was already unmapped (Damien Le Moal)
- Use of_property_present() instead of of_property_read_bool() when
testing for presence of non-boolean DT properties (Rob Herring)
- Advertise 1MB size if endpoint supports Resizable BARs, which was
inadvertently lost in v6.11 (Niklas Cassel)
TI J721E PCIe driver:
- Add PCIe support for J722S SoC (Siddharth Vadapalli)
- Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
us), before deasserting PERST# to ensure power and refclk are
stable (Siddharth Vadapalli)
TI Keystone PCIe controller driver:
- Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
Complex mode (Kishon Vijay Abraham I)
- Try to avoid unrecoverable SError for attempts to issue config
transactions when the link is down; this is racy but the best we
can do (Kishon Vijay Abraham I)
Miscellaneous:
- Reorganize kerneldoc parameter names to match order in function
signature (Julia Lawall)
- Fix sysfs reset_method_store() memory leak (Todd Kjos)
- Simplify pci_create_slot() (Ilpo Järvinen)
- Fix incorrect printf format specifiers in pcitest (Luo Yifan)"

firewire updates for v6.12
The batch of changes includes the followwing:
- Replacing tasklet with usual workqueue for isochronous context
- Replacing IDR with XArray
- Utilizing guard macro where possible
- Printing deprecation warning when enabling debug parameter of
firewire-ohci module
Additionally, it includes a single patch for sound subsystem which the
subsystem maintainer acked:
- Switching to nonatomic PCM operation
In FireWire subsystem, tasklet has been used as the bottom half of 1394
OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
been available, and some developers have proposed replacing tasklet with
BH workqueue. While it is fortunate that developers are still considering
the legacy subsystem, a simple replacement is not necessarily suitable.
As a first step towards dropping tasklet, I've investigated the
feasibility for 1394 OHCI isochronous context, and concluded that usual
workqueue is available. In the context, the batch of packets is processed
in the specific queue, thus the timing jitter caused by task scheduling is
not so critical. Additionally, DMA transmission can be scheduled
per-packet basis, therefore the context can be sleep between the operation
of transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long. These
characteristics suggest that usual workqueue is suitable, through BH
workqueues are not.
The replacement with usual workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to some
drivers in sound subsystem that spin-lock is not mandatory anymore during
isochronous packet processing.

"In the FireWire subsystem, tasklets have been used as the bottom half
of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
become available, and some developers have proposed replacing the
tasklet with a BH workqueue.
As a first step towards dropping tasklet use, the 1394 OHCI
isochronous context can use regular workqueues. In this context, the
batch of packets is processed in the specific queue, thus the timing

Additionally, DMA transmission can be scheduled per-packet basis,

Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future
Apart from the above, there are assorted thermal driver updates
Specifics:
- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki)
- Update the thermal sysfs code to store trip point attributes in
trip descriptors and get to trip points via attribute pointers

firewire: core: expose kernel API to schedule work item to process isochronous context
In packet-per-buffer mode for isochronous context of 1394 OHCI, software can schedule hardIRQ to the buffer in which the content of isochronous packet is processed. The actual behaviour is different between isochronous receive (IR) and transmit (IT) contexts in respect to isochronous cycle in which the hardIRQ occurs. In IR context, the hardIRQ occurs when the buffer is filled actually by the content of received packet. If there are any isochronous cycles in which the packet transmission is skipped, it is postponed to generate the hardIRQ in respect to the isochronous cycle. In IT context, software can schedule the content of packet every isochronous cycle including skipping, therefore the hardIRQ occurs in the isochronous cycle to which the software scheduled. ALSA firewire stack uses the packet-per-buffer mode for both IR/IT contexts. To process time stamp per packet (or per sample in some cases) steadily for media clock recovery against unexpected transmission skips, it uses an IT context to operate all of isochronous contexts by calls of fw_iso_context_flush_completions() in the bottom-half of hardIRQ for the IT context. Although it looks well to handle all of isochronous contexts in a single bottom-half context, it relatively takes longer time. In the future code integration (not yet), it is possible to apply parallelism method to process these context. In the case, it is useful to allow unit drivers to schedule work items to process these isochronous contexts. As a preparation, this commit exposes fw_iso_context_schedule_flush_completions() as a kernel API available by unit drivers. It is renamed from fw_iso_context_queue_work() since it is a counter part of fw_iso_context_flush_completions().

thermal: core: Update thermal zone registration documentation
The thermal sysfs API document is outdated. One of the problems with it is that is still documents thermal_zone_device_register() which does not exit any more and it does not reflect the current thermal zone operations definition. Replace the thermal_zone_device_register() description in it with a thermal_zone_device_register_with_trips() description, including an update of the thermal zone operations list.

CXL for v6.11 merge window
New Changes:
- Refactor to a common struct for DRAM and general media CXL events
- Add abstract distance calculation support for CXL
- Add CXL maturity map documentation to detail current state of CXL enabling
- Add warning on mixed CXL VH and RCH/RCD hierachy to inform unsupported config
- Replace ENXIO with EBUSY for inject poison limit reached via debugfs
- Replace ENXIO with EBUSY for inject poison cxl-test support
- XOR math fixup for DPA to SPA translation. Current math works for MODULO arithmetic
where HPA==SPA, however not for XOR decode.
- Move pci config read in cxl_dvsec_rr_decode() to avoid unnecessary acess
Fixes:
- Add a fix to address race condition in CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define

Merge tag 'cxl-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dave Jiang:
"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define
Misc:
- A warning has been added to inform users of an unsupported
configuration when mixing CXL VH and RCH/RCD hierarchies
- The ENXIO error code has been replaced with EBUSY for inject poison
limit reached via debugfs and cxl-test support
- Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
unnecessary PCI config reads
- A refactor to a common struct for DRAM and general media CXL
events"

Nothing hugely exciting happening in the documentation tree this time
around, mostly more of the usual:
- More Spanish, Italian, and Chinese translations
- A new script, scripts/checktransupdate.py, can be used to see which
commits have touched an (English) document since a given translation was
last updated.
- A couple of "best practices" suggestions (on Link: tags and off-list
discussions) that were not entirely at consensus level, but I concluded
they were close enough to accept.
- Some nice cleanups removing documentation for kernel parameters that have
not been recognized for ... a long time.

spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

gpio updates for v6.11-rc1
GPIOLIB core:
- rework kfifo handling rework in the character device code
- improve the labeling of GPIOs requested as interrupts and show more info
on interrupt-only GPIOs in debugfs
- remove unused APIs
- unexport interfaces that are only used from the core GPIO code
- drop the return value from gpiochip_set_desc_names() as it cannot fail
- move a string array definition out of a header and into a specific
compilation unit
- convert the last user of gpiochip_get_desc() other than GPIO core to using
a safer alternative
- use array_index_nospec() where applicable
New drivers:
- add a "virtual GPIO consumer" module that allows requesting GPIOs from actual
hardware and driving tests of the in-kernel GPIO API from user-space over
debugfs
- add a GPIO-based "sloppy" logic analyzer module useful for "first glance"
debugging on remote boards
Driver improvements:
- add support for a new model to gpio-pca953x
- lock GPIOs as interrupts in gpio-sim when the lines are requested as irqs
via the simulator domain + some other minor improvements
- improve error reporting in gpio-syscon
- convert gpio-ath79 to using dynamic GPIO base and range
- use pcibios_err_to_errno() for converting PCIBIOS error codes to errno
vaues in gpio-amd8111 and gpio-rdc321x
- allow building gpio-brcmstb for the BCM2835 architecture
DT bindings:
- convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
- document new properties for aspeed,gpio, fsl,qoriq-gpio and gpio-vf610
- document new compatibles for pca953x and fsl,qoriq-gpio
Documentation:
- document stricter behavior of the GPIO character device uAPI with regards to
reconfiguring requested line without direction set
- clarify the effect of the active-low flag on line values and edges
- remove documentation for the legacy GPIO API in order to stop tempting
people to use it
- document the preference for using pread() for reading edge events in the
sysfs API
Other:
- add an extended initializer to the interrupt simulator allowing to specify
a number of callbacks callers can use to be notified about irqs being
requested and released

tempting people to use it
- document the preference for using pread() for reading edge events
in the sysfs API
Other:
- add an extended initializer to the interrupt simulator allowing to
specify a number of callbacks callers can use to be notified about
irqs being requested and released"

pwm: Changes for v6.11-rc1
This contains the usual mix of fixes, cleanups, two new drivers and several dt binding updates. The fixes are for minor issues that are already old (4.11-rc1 and 3.9-rc1) and were found by code review and not during usage, so I didn't sent them for earlier inclusion. The changes to include/linux/mfd/stm32-timers.h and drivers/counter/stm32-timer-cnt.c are part of an immutable branch that will also be included in the mfd and counter PR. It changes some register definitions and affects the pwm-stm32 driver.
