* MTD changes
There's been no major core change, and a bunch of driver related
improvements, amongst them the conversion to of_property_present() for
non-boolean properties, the addition of the support for Fujitsu
MB85RS128TY FRAM, a couple of improvements to the phram driver and the
usual load of misc changes.
* Raw NAND changes
A new controller driver, from Nuvoton, has been merged.
Bastien Curutchet has contributed a series improving the Davinci
controller driver, both on the organization of the code, but also on the
performance side. The binding has also been converted to yaml, received
a new OOB layout and now supports on-die ECC engines.
The Qualcomm controller driver has been deeply cleaned to extract some
parts of the code into a shared file with the Qualcomm SPI memory
controller.
Aside from these main changes, the Cadence binding has been converted to
yaml, the brcmnand controller driver has received a small fix, otherwise
some more minor changes have also made their way in.
* SPI NAND changes
The SPI NAND subsystem has seen a great improvement, with the advent of
DTR operations (DDR operations, which may be extended to the address
cycles). The first vendor driver to benefit from these improvements is
the Winbond driver.
A new manufacturer driver is added SkyHigh, with a new constraint for
the core, it is impossible to disable the on-die ECC engine.
A Foresee device is also now supported.
* SPI NOR changes
Several flash entries have been added: Atmel AT25SF321, Spansion
S28HL256T and S28HL02GT.
Support for vcc-supply regulators and their DT bindings has been added.
The mx25u25635f entry has been dropped. The flash shares its ID with
mx25u25645g and both parts have an SFDP table. Removing their entry lets
them be driven by the generic SFDP-based driver.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Batch sizing of multiple BARs while memory decoding is disabled
instead of disabling/enabling decoding for each BAR individually;
this optimizes virtualized environments where toggling decoding
enable is expensive (Alex Williamson)
- Add host bridge .enable_device() and .disable_device() hooks for
bridges that need to configure things like Requester ID to StreamID
mapping when enabling devices (Frank Li)
- Extend struct pci_ecam_ops with .enable_device() and
.disable_device() hooks so drivers that use pci_host_common_probe()
instead of their own .probe() have a way to set the
.enable_device() callbacks (Marc Zyngier)
- Drop 'No bus range found' message so we don't complain when DTs
don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)
- Rename the drivers/pci/of_property.c struct of_pci_range to
of_pci_range_entry to avoid confusion with the global of_pci_range
in include/linux/of_address.h (Bjorn Helgaas)
Driver binding:
- Update resource request API documentation to encourage callers to
supply a driver name when requesting resources (Philipp Stanner)
- Export pci_intx_unmanaged() and pcim_intx() (always managed) so
callers of pci_intx() (which is sometimes managed) can explicitly
choose the one they need (Philipp Stanner)
- Convert drivers from pci_intx() to always-managed pcim_intx() or
never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)
- Remove pci_intx_unmanaged() since pci_intx() is now always
unmanaged and pcim_intx() is always managed (Philipp Stanner)
Error handling:
- Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
logging rather than building their own (Ilpo Järvinen)
- Move TLP Log handling to its own file (Ilpo Järvinen)
- Store number of supported End-End TLP Prefixes always so we can
read the correct number of DWORDs from the TLP Prefix Log (Ilpo
Järvinen)
- Read TLP Prefixes in addition to the Header Log in
pcie_read_tlp_log() (Ilpo Järvinen)
- Add pcie_print_tlp_log() to consolidate printing of TLP Header and
Prefix Log (Ilpo Järvinen)
- Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
BIOSes that don't configure it correctly (Takashi Iwai)
ASPM:
- Save parent L1 PM Substates config so when we restore it along with
an endpoint's config, the parent info isn't junk (Jian-Hong Pan)
Power management:
- Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
the system can't wake up from suspend (Werner Sembach)
Endpoint framework:
- Destroy the EPC device in devm_pci_epc_destroy(), which previously
didn't call devres_release() (Zijun Hu)
- Finish virtual EP removal in pci_epf_remove_vepf(), which
previously caused a subsequent pci_epf_add_vepf() to fail with
-EBUSY (Zijun Hu)
- Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
don't depend on the BAR_MASK reset value being larger than the
requested BAR size (Niklas Cassel)
- Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
reads from bypassing the iATU if we reduced the BAR size (Niklas
Cassel)
- Verify address alignment when programming iATU so we don't attempt
to write bits that are read-only because of the BAR size, which
could lead to directing accesses to the wrong address (Niklas
Cassel)
- Implement artpec6 pci_epc_features so we can rely on all drivers
supporting it so we can use it in EPC core code (Niklas Cassel)
- Check for BARs of fixed size to prevent endpoint drivers from
trying to change their size (Niklas Cassel)
- Verify that requested BAR size is a power of two when endpoint
driver sets the BAR (Niklas Cassel)
Endpoint framework tests:
- Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing
dma_chan_rx (Mohamed Khalfella)
- Correct the DMA MEMCPY test so it doesn't fail if the Endpoint
supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam)
- Add pci-epf-test and pci_endpoint_test support for capabilities
(Niklas Cassel)
- Add Endpoint test for consecutive BARs (Niklas Cassel)
- Remove redundant comparison from Endpoint BAR test because a > 1MB
BAR can always be exactly covered by iterating with a 1MB buffer
(Hans Zhang)
- Move and convert PCI Endpoint tests from tools/pci to Kselftests
(Manivannan Sadhasivam)
Apple PCIe controller driver:
- Convert StreamID mapping configuration from a bus notifier to the
.enable_device() and .disable_device() callbacks (Marc Zyngier)
Freescale i.MX6 PCIe controller driver:
- Add Requester ID to StreamID mapping configuration when enabling
devices (Frank Li)
- Use DWC core suspend/resume functions for imx6 (Frank Li)
- Add suspend/resume support for i.MX8MQ, i.MX8Q, and i.MX95 (Richard
Zhu)
- Add DT compatible string 'fsl,imx8q-pcie-ep' and driver support for
i.MX8Q series (i.MX8QM, i.MX8QXP, and i.MX8DXL) Endpoints (Frank
Li)
- Add DT binding for optional i.MX95 Refclk and driver support to
enable it if the platform hasn't enabled it (Richard Zhu)
- Configure PHY based on controller being in Root Complex or Endpoint
mode (Frank Li)
- Rely on dbi2 and iATU base addresses from DT via
dw_pcie_get_resources() instead of hardcoding them (Richard Zhu)
- Deassert apps_reset in imx_pcie_deassert_core_reset() since it is
asserted in imx_pcie_assert_core_reset() (Richard Zhu)
- Add missing reference clock enable or disable logic for IMX6SX,
IMX7D, IMX8MM (Richard Zhu)
- Remove redundant imx7d_pcie_init_phy() since
imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead
of syscon_regmap_lookup_by_phandle() followed by
of_property_read_u32_array() (Krzysztof Kozlowski)
Marvell MVEBU PCIe controller driver:
- Add MODULE_DEVICE_TABLE() to enable module autoloading (Liao Chen)
MediaTek PCIe Gen3 controller driver:
- Use clk_bulk_prepare_enable() instead of separate
clk_bulk_prepare() and clk_bulk_enable() (Lorenzo Bianconi)
- Rearrange reset assert/deassert so they're both done in the
*_power_up() callbacks (Lorenzo Bianconi)
- Document that Airoha EN7581 requires PHY init and power-on before
PHY reset deassert, unlike other MediaTek Gen3 controllers (Lorenzo
Bianconi)
- Move Airoha EN7581 post-reset delay from the en7581 clock .enable()
method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi)
- Sleep instead of delay during Airoha EN7581 power-up, since this is
a non-atomic context (Lorenzo Bianconi)
- Skip PERST# assertion on Airoha EN7581 during probe and
suspend/resume to avoid a hardware defect (Lorenzo Bianconi)
- Enable async probe to reduce system startup time (Douglas Anderson)
Microchip PolarFlare PCIe controller driver:
- Set up the inbound address translation based on whether the
platform allows coherent or non-coherent DMA (Daire McNamara)
- Update DT binding such that platforms are DMA-coherent by default
and must specify 'dma-noncoherent' if needed (Conor Dooley)
Mobiveil PCIe controller driver:
- Convert mobiveil-pcie.txt to YAML and update 'interrupt-names'
and 'reg-names' (Frank Li)
Qualcomm PCIe controller driver:
- Add DT SM8550 and SM8650 optional 'global' interrupt for link
events (Neil Armstrong)
- Add DT 'compatible' strings for IPQ5424 PCIe controller (Manikanta
Mylavarapu)
- If 'global' IRQ is supported for detection of Link Up events, tell
DWC core not to wait for link up (Krishna chaitanya chundru)
Renesas R-Car PCIe controller driver:
- Avoid passing stack buffer as resource name (King Dix)
Rockchip PCIe controller driver:
- Simplify clock and reset handling by using bulk interfaces (Anand
Moon)
- Pass typed rockchip_pcie (not void) pointer to
rockchip_pcie_disable_clocks() (Anand Moon)
- Return -ENOMEM, not success, when pci_epc_mem_alloc_addr() fails
(Dan Carpenter)
Rockchip DesignWare PCIe controller driver:
- Use dll_link_up IRQ to detect Link Up and enumerate devices so
users don't have to manually rescan (Niklas Cassel)
- Tell DWC core not to wait for link up since the 'sys' interrupt is
required and detects Link Up events (Niklas Cassel)
Synopsys DesignWare PCIe controller driver:
- Don't wait for link up in DWC core if driver can detect Link Up
event (Krishna chaitanya chundru)
- Update ICC and OPP votes after Link Up events (Krishna chaitanya
chundru)
- Always stop link in dw_pcie_suspend_noirq(), which is required at
least for i.MX8QM to re-establish link on resume (Richard Zhu)
- Drop racy and unnecessary LTSSM state check before sending
PME_TURN_OFF message in dw_pcie_suspend_noirq() (Richard Zhu)
- Add struct of_pci_range.parent_bus_addr for devices that need their
immediate parent bus address, not the CPU address, e.g., to program
an internal Address Translation Unit (iATU) (Frank Li)
TI DRA7xx PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead of
syscon_regmap_lookup_by_phandle() followed by
of_parse_phandle_with_fixed_args() or of_property_read_u32_index()
(Krzysztof Kozlowski)
Xilinx Versal CPM PCIe controller driver:
- Add DT binding and driver support for Xilinx Versal CPM5
(Thippeswamy Havalige)
MicroSemi Switchtec management driver:
- Add Microchip PCI100X device IDs (Rakesh Babu Saladi)
Miscellaneous:
- Move reset related sysfs code from pci.c to pci-sysfs.c where other
similar code lives (Ilpo Järvinen)
- Simplify reset_method_store() memory management by using __free()
instead of explicit kfree() cleanup (Ilpo Järvinen)
- Constify struct bin_attribute for sysfs, VPD, P2PDMA, and the IBM
ACPI hotplug driver (Thomas Weißschuh)
- Remove redundant PCI_VSEC_HDR and PCI_VSEC_HDR_LEN_SHIFT (Dongdong
Zhang)
- Correct documentation of the 'config_acs=' kernel parameter
(Akihiko Odaki)"

Loongarch:
* Clear LLBCTL if secondary mmu mapping changes.
* Add hypercall service support for usermode VMM.
x86:
* Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a
direct call to kvm_tdp_page_fault() when RETPOLINE is enabled.
* Ensure that all SEV code is compiled out when disabled in Kconfig, even
if building with less brilliant compilers.
* Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes.
* Use str_enabled_disabled() to replace open coded strings.
* Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache
prior to every VM-Enter.
* Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities
instead of just those where KVM needs to manage state and/or explicitly
enable the feature in hardware. Along the way, refactor the code to make
it easier to add features, and to make it more self-documenting how KVM
is handling each feature.
* Rework KVM's handling of VM-Exits during event vectoring; this plugs holes
where KVM unintentionally puts the vCPU into infinite loops in some scenarios
(e.g. if emulation is triggered by the exit), and brings parity between VMX
and SVM.
* Add pending request and interrupt injection information to the kvm_exit and
kvm_entry tracepoints respectively.
* Fix a relatively benign flaw where KVM would end up redoing RDPKRU when
loading guest/host PKRU, due to a refactoring of the kernel helpers that
didn't account for KVM's pre-checking of the need to do WRPKRU.
* Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE
specifically went to userspace, and all the others did not; the new code
need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not.
* As part of enabling TDX virtual machines, support support separation of
private/shared EPT into separate roots. When TDX will be enabled, operations
on private pages will need to go through the privileged TDX Module via SEAMCALLs;
as a result, they are limited and relatively slow compared to reading a PTE.
The patches included in 6.14 allow KVM to keep a mirror of the private EPT in
host memory, and define entries in kvm_x86_ops to operate on external page
tables such as the TDX private EPT.
* The recently introduced conversion of the NX-page reclamation kthread to
vhost_task moved the task under the main process. The task is created as
soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that
didn't expect to see any child task of the VM process until it started
creating its own userspace threads. In particular crosvm refuses to fork()
if procfs shows any child task, so unbreak it by creating the task lazily.
This is arguably a userspace bug, as there can be other kinds of legitimate
worker tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they show
as "Kthread: 1" in proc/.../status?
x86 - Intel:
* Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit
while L2 is active, while ultimately results in a hardware-accelerated L1
EOI effectively being lost.
* Honor event priority when emulating Posted Interrupt delivery during nested
VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the
interrupt.
* Rework KVM's processing of the Page-Modification Logging buffer to reap
entries in the same order they were created, i.e. to mark gfns dirty in the
same order that hardware marked the page/PTE dirty.
* Misc cleanups.
Generic:
* Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when
setting memory regions and add a dedicated API for setting KVM-internal
memory regions. The API can then explicitly disallow all flags for
KVM-internal memory regions.
* Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.
* Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that
isn't yet onlined.
* Gracefully handle xarray insertion failures; even though such failures are
impossible in practice after xa_reserve(), reserving an entry is always followed
by xa_store() which does not know (or differentiate) whether there was an
xa_reserve() before or not.
RISC-V:
* Zabha, Svvptc, and Ziccrse extension support for guests. None of them
require anything in KVM except for detecting them and marking them
as supported; Zabha adds byte and halfword atomic operations, while the
others are markers for specific operation of the TLB and of LL/SC
instructions respectively.
* Virtualize SBI system suspend extension for Guest/VM
* Support firmware counters which can be used by the guests to collect
statistics about traps that occur in the host.
Selftests:
* Rework vcpu_get_reg() to return a value instead of using an out-param, and
update all affected arch code accordingly.
* Convert the max_guest_memory_test into a more generic mmu_stress_test.
The basic gist of the "conversion" is to have the test do mprotect() on
guest memory while vCPUs are accessing said memory, e.g. to verify KVM
and mmu_notifiers are working as intended.
* Play nice with treewrite builds of unsupported architectures, e.g. arm
(32-bit), as KVM selftests' Makefile doesn't do anything to ensure the
target architecture is actually one KVM selftests supports.
* Use the kernel's $(ARCH) definition instead of the target triple for arch
specific directories, e.g. arm64 instead of aarch64, mainly so as not to
be different from the rest of the kernel.
* Ensure that format strings for logging statements are checked by the
compiler even when the logging statement itself is disabled.
* Attempt to whack the last LLC references/misses mole in the Intel PMU
counters test by adding a data load and doing CLFLUSH{OPT} on the data
instead of the code being executed. It seems that modern Intel CPUs
have learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that events
are counting correctly without actually knowing what the events count
given the underlying hardware; this can happen if Intel reuses a
formerly microarchitecture-specific event encoding as an architectural
event, as was the case for Top-Down Slots.

EFI updates for v6.14
- Increase the headroom in the EFI memory map allocation created by the EFI stub. This is needed because event callbacks called during ExitBootServices() may cause fragmentation, and reallocation is not allowed after that. - Drop obsolete UGA graphics code and switch to a more ergonomic API to traverse handle buffers. Simplify some error paths using a __free() helper while at it. - Fix some W=1 warnings when CONFIG_EFI=n - Rely on the dentry cache to keep track of the contents of the efivarfs filesystem, rather than using a separate linked list. - Improve and extend efivarfs test cases. - Synchronize efivarfs with underlying variable store on resume from hibernation - this is needed because the firmware itself or another OS running on the same machine may have modified it. - Fix x86 EFI stub build with GCC 15. - Fix kexec/x86 false positive warning in EFI memory attributes table sanity check. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQQm/3uucuRGn1Dmh0wbglWLn0tXAUCZ5IH+gAKCRAwbglWLn0t XHyMAP9Mqn5dD4XT22gvTRUrJuVYFLBlN+9d8ysRMjRVCzGwCQEAvCUJMy5Kje0J h9i2InWjjPOVATx5hTrEoIEl96BGOgk= =3Hnk -----END PGP SIGNATURE----- Merge tag 'efi-next-for-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi Pull EFI updates from Ard Biesheuvel: - Increase the headroom in the EFI memory map allocation created by the EFI stub.

soc: driver updates for 6.14
These are changes to SoC specific drivers and DT bindings that don't have
a separate subsystem tree, or that get grouped here for simplicity.
Nothing out of the ordinary for the 6.14 release here:
- Most of the updates are for Qualcomm specific drivers, adding support
for additional SoCs in the exssting drivers, and support for wrapped
encryption key access in the SCM firmware.
- The Arm SCMI firmware code gains support for having multiple
instances of firmware running, and better module auto loading.
- A few minor updates for litex, samsung, ti, tegra, mediatek, imx and
renesas platforms.
- Reset controller updates for amlogic, to add support for the A1 soc
and clean up the existing code.
- Memory controller updates for ti davinci aemif, refactoring the code
and adding a few interfaces to other drivers.

soc: devicetree changes for 6.14
We see the addition of eleven new SoCs, including a total of sixx arm64
chips from Qualcomm alone. Overall, the Qualcomm platforms once again
make up the majority of all changes, after a couple of quieter releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of
the V4H (R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips
using Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial
IOT platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that
only need new devicetree files. Two additional SoCs in new
families are part of a separate branch.
There are 48 new machines in total, including six arm32 ones based
on aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores,
and a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP, Mediatek,
Qualcomm, Renesas and Rockchips and cover development boards, phones,
laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features.

Pull SoC devicetree updates from Arnd Bergmann:
"We see the addition of eleven new SoCs, including a total of sixx
arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
again make up the majority of all changes, after a couple of quieter
releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
(R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that only
need new devicetree files. Two additional SoCs in new families are
part of a separate branch.
There are 48 new machines in total, including six arm32 ones based on
aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
Mediatek, Qualcomm, Renesas and Rockchips and cover development
boards, phones, laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features"

soc: new SoC support for 6.14
Two new SoC families are added here, with devicetree files and
a little bit of infrastructure to allow booting:
- Blaize BLZP1600 is an AI chip using custom GSP (Graph Streaming
Processor) cores for computation, and two small Cortex-A53 cores
that run the operating system.
- SpacemiT K1 is a 64-bit RISC-V chip, using eight custom RVA22
compatible CPU cores with vector support.
Also marketed at AI applications, it has a much slower NPU compared
to BLZP1600, but in turn focuses on the CPU performance

of/fdt: Restore possibility to use both ACPI and FDT from bootloader
There are cases when the bootloader provides information to the kernel in both ACPI and DTB, not interchangeably. One such use case is virtual machines in Android. When running on x86, the Android Virtualization Framework (AVF) boots VMs with ACPI like it is usually done on x86 (i.e. the virtual LAPIC, IOAPIC, HPET, PCI MMCONFIG etc are described in ACPI) but also passes various AVF-specific boot parameters in DTB. This allows reusing the same implementations of various AVF components on both arm64 and x86. Commit |

kvm: defer huge page recovery vhost task to later
Some libraries want to ensure they are single threaded before forking,
so making the kernel's kvm huge page recovery process a vhost task of
the user process breaks those. The minijail library used by crosvm is
one such affected application.
Defer the task to after the first VM_RUN call, which occurs after the
parent process has forked all its jailed processes. This needs to happen
only once for the kvm instance, so introduce some general-purpose
infrastructure for that, too. It's similar in concept to pthread_once;
except it is actually usable, because the callback takes a parameter.

Pull x86 TDX updates from Dave Hansen:
"Intel Trust Domain updates.
The existing TDX code needs a _bit_ of metadata from the TDX module.
But KVM is going to need a bunch more very shortly. Rework the
interface with the TDX module to be more consistent and handle the new
higher volume.
The TDX module has added a few new features. The first is a promise
not to clobber RBP under any circumstances. Basically the kernel now
will refuse to use any modules that don't have this promise. Second,
enable the new "REDUCE_VE" feature. This ensures that the TDX module
will not send some silly virtualization exceptions that the guest had
no good way to handle anyway.
- Centralize global metadata infrastructure
- Use new TDX module features for exception suppression and RBP
clobbering"

perf-tools changes for v6.14
There are a lot of changes in the perf tools in this cycle.
build
-----
* Use generic syscall table to generate syscall numbers on supported archs.
* This also enables to get rid of libaudit which was used for syscall numbers.
* Remove python2 support as it's deprecated for years.
* Fix issues on static build with libzstd.
perf record
-----------
* Intel-PT supports "aux-action" config term to pause or resume tracing in
the aux-buffer. Users can start the intel_pt event as "started-paused" and
configure other events to control the Intel-PT tracing.
# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname
This requires the kernel support (which was added in v6.13).
perf lock
---------
* 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs with BPF.
Those dynamic locks would have "&" prefix in the name to distinguish them
from ordinary (static) locks.
# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol
2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)
1 1.18 us 1.18 us 1.18 us ffff9d5e852d3538 &task_struct (mutex)
4 1.12 us 354 ns 279 ns ffff9d5e841ca800 &kmalloc-cg-512 (mutex)
2 859 ns 617 ns 429 ns ffffffffa41c3620 delayed_uprobe_lock (mutex)
3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)
This also requires the kernel/BPF support (which was added in v6.13).
perf ftrace
-----------
* 'perf ftrace latency' command gets a couple of options to support linear
buckets instead of exponential. Also it's possible to specify max and
min latency for the linear buckets.
# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |
0 - 200 ns | 186 | ### |
200 - 300 ns | 256 | ##### |
300 - 400 ns | 364 | ####### |
400 - 500 ns | 223 | #### |
500 - 600 ns | 111 | ## |
600 - 700 ns | 41 | |
700 - 800 ns | 141 | ## |
800 - ... ns | 169 | ### |
# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236
* As you can see in the above example, it nows shows the statistics at the
end so that users can see the avg/max/min latencies easily.
* 'perf ftrace profile' command has --graph-opts option like 'perf ftrace
trace' so that it can control the tracing behaviors in the same way.
For example, it can limit the function call depth or threshold.
perf script
-----------
* Improve physical memory resolution in 'mem-phys-addr' script by parsing
/proc/iomem file.
# perf script mem-phys-addr -- find /
...
Event: mem_inst_retired.all_loads:P

Merge tag 'perf-tools-for-v6.14-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf-tools updates from Namhyung Kim:
"There are a lot of changes in the perf tools in this cycle.
build:
- Use generic syscall table to generate syscall numbers on supported
archs
- This also enables to get rid of libaudit which was used for syscall
numbers
- Remove python2 support as it's deprecated for years
- Fix issues on static build with libzstd
perf record:
- Intel-PT supports "aux-action" config term to pause or resume
tracing in the aux-buffer. Users can start the intel_pt event as
"started-paused" and configure other events to control the Intel-PT
tracing:
# perf record --kcore -e intel_pt/aux-action=start-paused/ \
-e syscalls:sys_enter_newuname/aux-action=resume/ \
-e syscalls:sys_exit_newuname/aux-action=pause/ -- uname
This requires kernel support (which was added in v6.13)
perf lock:
- 'perf lock contention' command has an ability to symbolize locks in
dynamically allocated objects using slab cache name when it runs
with BPF. Those dynamic locks would have "&" prefix in the name to
distinguish them from ordinary (static) locks
# perf lock con -abl -E 5 sleep 1
contended total wait max wait avg wait address symbol
2 1.95 us 1.77 us 975 ns ffff9d5e852d3498 &task_struct (mutex)

3 691 ns 388 ns 230 ns ffffffffa41c0940 pack_mutex (mutex)
This also requires kernel/BPF support (which was added in v6.13)
perf ftrace:
- 'perf ftrace latency' command gets a couple of options to support
linear buckets instead of exponential. Also it's possible to
specify max and min latency for the linear buckets:
# perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \
--min-latency=200 --max-latency=800 -- sleep 1
# DURATION | COUNT | GRAPH |
0 - 200 ns | 186 | ### |
200 - 300 ns | 256 | ##### |
300 - 400 ns | 364 | ####### |
400 - 500 ns | 223 | #### |

# statistics (in nsec)
total time: 2162212
avg time: 967
max time: 16817
min time: 132
count: 2236
- As you can see in the above example, it nows shows the statistics
at the end so that users can see the avg/max/min latencies easily
- 'perf ftrace profile' command has --graph-opts option like 'perf
ftrace trace' so that it can control the tracing behaviors in the
same way. For example, it can limit the function call depth or
threshold
perf script:
- Improve physical memory resolution in 'mem-phys-addr' script by
parsing /proc/iomem file
# perf script mem-phys-addr -- find /

* Raw NAND changes
A new controller driver, from Nuvoton, has been merged. Bastien Curutchet has contributed a series improving the Davinci controller driver, both on the organization of the code, but also on the performance side. The binding has also been converted to yaml, received a new OOB layout and now supports on-die ECC engines. The Qualcomm controller driver has been deeply cleaned to extract some parts of the code into a shared file with the Qualcomm SPI memory controller. Aside from these main changes, the Cadence binding has been converted to yaml, the brcmnand controller driver has received a small fix, otherwise some more minor changes have also made their way in. * SPI NAND changes The SPI NAND subsystem has seen a great improvement, with the advent of DTR operations (DDR operations, which may be extended to the address cycles). The first vendor driver to benefit from these improvements is the Winbond driver. A new manufacturer driver is added SkyHigh, with a new constraint for the core, it is impossible to disable the on-die ECC engine.

Fix atomic64 operations on some architectures for the tracing ring buffer:
- Have emulating atomic64 use arch_spin_locks instead of raw_spin_locks
The tracing ring buffer events have a small timestamp that holds the
delta between itself and the event before it. But this can be tricky
to update when interrupts come in. It originally just set the deltas
to zero for events that interrupted the adding of another event which
made all the events in the interrupt have the same timestamp as the
event it interrupted. This was not suitable for many tools, so it
was eventually fixed. But that fix required adding an atomic64 cmpxchg
on the timestamp in cases where an event was added while another
event was in the process of being added.
Originally, for 32 bit architectures, the manipulation of the 64 bit
timestamp was done by a structure that held multiple 32bit words to hold
parts of the timestamp and a counter. But as updates to the ring buffer
were done, maintaining this became too complex and was replaced by the
atomic64 generic operations which are now used by both 64bit and 32bit
architectures. Shortly after that, it was reported that riscv32 and
other 32 bit architectures that just used the generic atomic64 were
locking up. This was because the generic atomic64 operations defined in
lib/atomic64.c uses a raw_spin_lock() to emulate an atomic64 operation.
The problem here was that raw_spin_lock() can also be traced by the
function tracer (which is commonly used for debugging raw spin locks).
Since the function tracer uses the tracing ring buffer, which now is being
traced internally, this was triggering a recursion and setting off a
warning that the spin locks were recusing.
There's no reason for the code that emulates atomic64 operations to be
using raw_spin_locks which have a lot of debugging infrastructure attached
to them (depending on the config options). Instead it should be using
the arch_spin_lock() which does not have any infrastructure attached to
them and is used by low level infrastructure like RCU locks, lockdep
and of course tracing. Using arch_spin_lock()s fixes this issue.
- Do not trace in NMI if the architecture uses emulated atomic64 operations
Another issue with using the emulated atomic64 operations that uses
spin locks to emulate the atomic64 operations is that they cannot be
used in NMI context. As an NMI can trigger while holding the atomic64
spin locks it can try to take the same lock and cause a deadlock.
Have the ring buffer fail recording events if in NMI context and the
architecture uses the emulated atomic64 operations.

tracing updates for v6.14:
- Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Update the Rust tracepoint code to use the C code too There was some duplication of the tracepoint code for Rust that did the same logic as the C code. Add a helper that makes it possible for both algorithms to use the same logic in one place. - Add poll to trace event hist files It is useful to know when an event is triggered, or even with some filtering. Since hist files of events get updated when active and the event is triggered, allow applications to poll the hist file and wake up when an event is triggered. This will let the application know that the event it is waiting for happened. - Add :mod: command to enable events for current or future modules The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Add the command where if ':mod:<module>' is written into set_event, then either all the modules events are enabled if it is loaded, or cache it so that the module's events are enabled when it is loaded. This also works from the kernel command line, where "trace_event=:mod:<module>", when the module is loaded at boot up, its events will be enabled then. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ5EbMxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkZsAP9Amgx9frSbR1pn1t0I3wVnQx7khgOu s/b8Ro+vjTx1/QD/RN2AA7f+HK4F27w3Aqfrs0nKXAPtXWsJ9Epp8raG5w8= =Pg+4 -----END PGP SIGNATURE----- Merge tag 'trace-v6.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated.

This also works from the kernel command line, where "trace_event=:mod:<module>", when the module is loaded at boot up, its events will be enabled then. * tag 'trace-v6.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) tracing: Fix output of set_event for some cached module events tracing: Fix allocation of printing set_event file content tracing: Rename update_cache() to update_mod_cache() tracing: Fix #if CONFIG_MODULES to #ifdef CONFIG_MODULES selftests/ftrace: Add test that tests event :mod: commands tracing: Cache ":mod:" events for modules not loaded yet tracing: Add :mod: command to enabled module events selftests/tracing: Add hist poll() support test tracing/hist: Support POLLPRI event for poll on histogram tracing/hist: Add poll(POLLIN) support on hist file tracing: Fix using ret variable in tracing_set_tracer() tracepoint: Reduce duplication of __DO_TRACE_CALL tracing/string: Create and use __free(argv_free) in trace_dynevent.c tracing: Switch trace_stat.c code over to use guard() tracing: Switch trace_stack.c code over to use guard() tracing: Switch trace_osnoise.c code over to use guard() and __free() tracing: Switch trace_events_synth.c code over to use guard() tracing: Switch trace_events_filter.c code over to use guard() tracing: Switch trace_events_trigger.c code over to use guard() tracing: Switch trace_events_hist.c code over to use guard() ... |

docs: dt-bindings: Document preferred line wrapping
There are some patches with long lines as a result of checkpatch enforcing 100, not 80, but checkpatch is only a tool not a coding style. The Linux Kernel Coding Style is still clear here on preferred limit. Mentioned preferred style of wrapping long lines in DTS, based on Linux Kernel Coding Style.
