63eb28bb14 ARM:
- Host driver for GICv5, the next generation interrupt controller for
   arm64, including support for interrupt routing, MSIs, interrupt
   translation and wired interrupts.
 
 - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
   GICv5 hardware, leveraging the legacy VGIC interface.
 
 - Userspace control of the 'nASSGIcap' GICv3 feature, allowing
   userspace to disable support for SGIs w/o an active state on hardware
   that previously advertised it unconditionally.
 
 - Map supporting endpoints with cacheable memory attributes on systems
   with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
   maintenance on the address range.
 
 - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
   hypervisor to inject external aborts into an L2 VM and take traps of
   masked external aborts to the hypervisor.
 
 - Convert more system register sanitization to the config-driven
   implementation.
 
 - Fixes to the visibility of EL2 registers, namely making VGICv3 system
   registers accessible through the VGIC device instead of the ONE_REG
   vCPU ioctls.
 
 - Various cleanups and minor fixes.
 
 LoongArch:
 
 - Add stat information for in-kernel irqchip
 
 - Add tracepoints for CPUCFG and CSR emulation exits
 
 - Enhance in-kernel irqchip emulation
 
 - Various cleanups.
 
 RISC-V:
 
 - Enable ring-based dirty memory tracking
 
 - Improve perf kvm stat to report interrupt events
 
 - Delegate illegal instruction trap to VS-mode
 
 - MMU improvements related to upcoming nested virtualization
 
 s390x
 
 - Fixes
 
 x86:
 
 - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC,
   PIC, and PIT emulation at compile time.
 
 - Share device posted IRQ code between SVM and VMX and
   harden it against bugs and runtime errors.
 
 - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1)
   instead of O(n).
 
 - For MMIO stale data mitigation, track whether or not a vCPU has access to
   (host) MMIO based on whether the page tables have MMIO pfns mapped; using
   VFIO is prone to false negatives
 
 - Rework the MSR interception code so that the SVM and VMX APIs are more or
   less identical.
 
 - Recalculate all MSR intercepts from scratch on MSR filter changes,
   instead of maintaining shadow bitmaps.
 
 - Advertise support for LKGS (Load Kernel GS base), a new instruction
   that's loosely related to FRED, but is supported and enumerated
   independently.
 
 - Fix a user-triggerable WARN that syzkaller found by setting the vCPU
   in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU
   into VMX Root Mode (post-VMXON).  Trying to detect every possible path
   leading to architecturally forbidden states is hard and even risks
   breaking userspace (if it goes from valid to valid state but passes
   through invalid states), so just wait until KVM_RUN to detect that
   the vCPU state isn't allowed.
 
 - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of
   APERF/MPERF reads, so that a "properly" configured VM can access
   APERF/MPERF.  This has many caveats (APERF/MPERF cannot be zeroed
   on vCPU creation or saved/restored on suspend and resume, or preserved
   over thread migration let alone VM migration) but can be useful whenever
   you're interested in letting Linux guests see the effective physical CPU
   frequency in /proc/cpuinfo.
 
 - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been
   created, as there's no known use case for changing the default
   frequency for other VM types and it goes counter to the very reason
   why the ioctl was added to the vm file descriptor.  And also, there
   would be no way to make it work for confidential VMs with a "secure"
   TSC, so kill two birds with one stone.
 
 - Dynamically allocation the shadow MMU's hashed page list, and defer
   allocating the hashed list until it's actually needed (the TDP MMU
   doesn't use the list).
 
 - Extract many of KVM's helpers for accessing architectural local APIC
   state to common x86 so that they can be shared by guest-side code for
   Secure AVIC.
 
 - Various cleanups and fixes.
 
 x86 (Intel):
 
 - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest.
   Failure to honor FREEZE_IN_SMM can leak host state into guests.
 
 - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent
   L1 from running L2 with features that KVM doesn't support, e.g. BTF.
 
 x86 (AMD):
 
 - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the
   nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty
   much a static condition and therefore should never happen, but still).
 
 - Fix a variety of flaws and bugs in the AVIC device posted IRQ code.
 
 - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware
   supports) instead of rejecting vCPU creation.
 
 - Extend enable_ipiv module param support to SVM, by simply leaving
   IsRunning clear in the vCPU's physical ID table entry.
 
 - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by
   erratum #1235, to allow (safely) enabling AVIC on such CPUs.
 
 - Request GA Log interrupts if and only if the target vCPU is blocking,
   i.e. only if KVM needs a notification in order to wake the vCPU.
 
 - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the
   vCPU's CPUID model.
 
 - Accept any SNP policy that is accepted by the firmware with respect to
   SMT and single-socket restrictions.  An incompatible policy doesn't put
   the kernel at risk in any way, so there's no reason for KVM to care.
 
 - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and
   use WBNOINVD instead of WBINVD when possible for SEV cache maintenance.
 
 - When reclaiming memory from an SEV guest, only do cache flushes on CPUs
   that have ever run a vCPU for the guest, i.e. don't flush the caches for
   CPUs that can't possibly have cache lines with dirty, encrypted data.
 
 Generic:
 
 - Rework irqbypass to track/match producers and consumers via an xarray
   instead of a linked list.  Using a linked list leads to O(n^2) insertion
   times, which is hugely problematic for use cases that create large
   numbers of VMs.  Such use cases typically don't actually use irqbypass,
   but eliminating the pointless registration is a future problem to
   solve as it likely requires new uAPI.
 
 - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *",
   to avoid making a simple concept unnecessarily difficult to understand.
 
 - Decouple device posted IRQs from VFIO device assignment, as binding a VM
   to a VFIO group is not a requirement for enabling device posted IRQs.
 
 - Clean up and document/comment the irqfd assignment code.
 
 - Disallow binding multiple irqfds to an eventfd with a priority waiter,
   i.e.  ensure an eventfd is bound to at most one irqfd through the entire
   host, and add a selftest to verify eventfd:irqfd bindings are globally
   unique.
 
 - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues
   related to private <=> shared memory conversions.
 
 - Drop guest_memfd's .getattr() implementation as the VFS layer will call
   generic_fillattr() if inode_operations.getattr is NULL.
 
 - Fix issues with dirty ring harvesting where KVM doesn't bound the
   processing of entries in any way, which allows userspace to keep KVM
   in a tight loop indefinitely.
 
 - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking,
   now that KVM no longer uses assigned_device_count as a heuristic for
   either irqbypass usage or MDS mitigation.
 
 Selftests:
 
 - Fix a comment typo.
 
 - Verify KVM is loaded when getting any KVM module param so that attempting
   to run a selftest without kvm.ko loaded results in a SKIP message about
   KVM not being loaded/enabled (versus some random parameter not existing).
 
 - Skip tests that hit EACCES when attempting to access a file, and rpint
   a "Root required?" help message.  In most cases, the test just needs to
   be run with elevated permissions.

Linus Torvalds
8be4d31cb8 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.
 
 Device drivers
 --------------
 
  - Add a new Broadcom driver for 800G Ethernet (bnge).

Pull networking updates from Jakub Kicinski:
 "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

  Device drivers:

   - Add a new Broadcom driver for 800G Ethernet (bnge)

   - Add a standalone driver for Microchip ZL3073x DPLL

0f46f50845 soc: driver updates for 6.17
Changes are all over the place, but very little sticks out as
 noteworthy.
 
 There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
 I/O chip, along with hooking it up to the pinctrl and clk frameworks.
 
 The reset controller and memory subsystems have mainly small updates,
 but there are two new reset drivers for the K230 and VC1800B SoCs,
 and new memory driver support for Tegra264.
 
 The ARM SMCCC and SCMI firmware drivers gain a few more features that
 should help them be supported across more environments. Similarly,
 the SoC specific firmware on Tegra and Qualcomm get minor enhancements
 and chip support.
 
 In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
 overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
 grow to support more chips, while the Hisilicon, Mediatek and Renesas
 drivers see mostly janitorial fixes.

115e74a29b soc: dt changes for 6.17
There are a few new variants of existing chips:
 
  - mt6572 is an older mobile phone chip from mediatek that was
    extremely popular a decade ago but never got upstreamed until now.
 
  - exynos2200 is a recent high-end mobile phone chip used in a
    few Samsung phones like the Galaxy S22
 
  - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
    (R8A779H0) and used in automotive applications
 
  - Tegra264 is a new chip from NVIDIA, but support is fairly minimal
    for now, and not much information is public about it.
 
 There are five more chips in a separate branch, as those are new
 chip families that I merged along with the necessary infrastructure.
 
 New board support is not that exciting, with a total of 33 newly
 added machines here:
 
  - Evaluation platforms for the chips above, plus TI am62d2 and
    Sophgo sg2042.
 
  - Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
    plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
    imx95.
 
  - Two newly added ASPEED BMC based motherboards, and one that got
    removed
 
  - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
    msm8976 SoCs
 
  - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
 
  - A set-top box based on Amlogic meson-gxm.
 
 Updates for existing machines are spread over all the above families.
 One notable change here is support for the RP1 I/O chip used in
 Raspberry Pi 5.

Pull power management updates from Rafael Wysocki:
 "As is tradition, cpufreq is the part with the largest number of
  updates that include core fixes and cleanups as well as updates of
  several assorted drivers, but there are also quite a few updates
  related to system sleep, mostly focused on asynchronous suspend and
  resume of devices and on making the integration of system suspend
  and resume with runtime PM easier.

  Runtime PM is also updated to allow some code duplication in drivers
  to be eliminated going forward and to work more consistently overall
  in some cases.

  Apart from that, there are some driver core updates related to PM
  domains that should help to address ordering issues with devm_ cleanup
  routines relying on PM domains, some assorted devfreq updates
  including core fixes and cleanups, tooling updates, and documentation
  and MAINTAINERS updates.

     governor initialization error path in it, and clean it up (Lifeng

8c493cc91f PCI/pwrctrl: Create pwrctrl devices only when CONFIG_PCI_PWRCTRL is enabled
If devicetree describes power supplies related to a PCI device, we
unnecessarily created a pwrctrl device even if CONFIG_PCI_PWRCTL was not
enabled.

We only need pci_pwrctrl_create_device() when CONFIG_PCI_PWRCTRL is
enabled.  Compile it out when CONFIG_PCI_PWRCTRL is not enabled.

When pci_pwrctrl_create_device() creates and returns a pwrctrl device,
pci_scan_device() doesn't enumerate the PCI device. It assumes the pwrctrl
core will rescan the bus after turning on the power. However, if
CONFIG_PCI_PWRCTRL is not enabled, the rescan never happens, which breaks
PCI enumeration on any system that describes power supplies in devicetree
but does not use pwrctrl.

Jim reported that some brcmstb platforms break this way.  The brcmstb
driver is still broken if CONFIG_PCI_PWRCTRL is enabled, but this commit at
least allows brcmstb to work when it's NOT enabled.

6f490bb4a9 PCI: hv: Use the correct hypercall for unmasking interrupts on nested
Running as nested root on MSHV imposes a different requirement
for the pci-hyperv controller.

In this setup, the interrupt will first come to the L1 (nested) hypervisor,
which will deliver it to the appropriate root CPU. Instead of issuing the
RETARGET hypercall, issue the MAP_DEVICE_INTERRUPT hypercall to L1 to
complete the setup.

Rename hv_arch_irq_unmask() to hv_irq_retarget_interrupt().

5f83d6337c PCI: hv: Switch to msi_create_parent_irq_domain()
Move away from the legacy MSI domain setup, switch to use
msi_create_parent_irq_domain().

While doing the conversion, I noticed that hv_compose_msi_msg() is doing
more than it is supposed to (composing message). This function also
allocates and populates struct tran_int_desc, which should be done in
hv_pcie_domain_alloc() instead. It works, but it is not the correct design.
However, I have no hardware to test such change, therefore I leave a TODO
note.

68ea85df15 PCI/MSI: Prevent recursive locking in pci_msix_write_tph_tag()
pci_msix_write_tph_tag() takes the per device MSI descriptor mutex and then
invokes msi_domain_get_virq(), which takes the same mutex again. That
obviously results in a system hang which is exposed by a softlockup or
lockdep warning.

Move the lock guard after the invocation of msi_domain_get_virq() to fix
this.

643c0c9d04 PCI: apple: Add tracking of probed root ports
The apple driver relies on being able to directly find the matching root
port structure from the platform device that represents this port.

A previous hack stashed a pointer to the root port structure in the config
window private pointer, but that ended up relying on assumptions that break
other drivers.

Instead, bite the bullet and track the association as part of the driver
itself as a list of probed root ports.

This reverts commit 631b2af2f3 ("PCI/ACPI: Fix allocated memory release
on error in pci_acpi_scan_root()").

The reverted patch causes the 'ri->cfg' and 'root_ops' resources to be
released multiple times.

When acpi_pci_root_create() fails, these resources have already been
released internally by the __acpi_pci_root_release_info() function.

Releasing them again in pci_acpi_scan_root() leads to incorrect behavior
and potential memory issues.

We plan to resolve the issue using a more appropriate fix.

Layer State Changed, only that event is cleared and not Presence Detect
Changed.  The object of the commit is thus defeated.

That's because pciehp_ist() computes the events to clear based on the local
"events" variable instead of "ctrl->pending_events".  The former contains
the events that had occurred when pciehp_ist() was entered, whereas the
latter also contains events that have accumulated while awaiting DPC
recovery.

In practice, the order of PDC and DLLSC events is arbitrary and the delay
in-between can be several milliseconds.

So change the logic to always clear PDC events, even if they come after an
initial DLLSC event.

49d63971f9 misc: rp1: RaspberryPi RP1 misc driver
The RaspberryPi RP1 is a PCI multi function device containing
peripherals ranging from Ethernet to USB controller, I2C, SPI
and others.

Implement a bare minimum driver to operate the RP1, leveraging
actual OF based driver implementations for the on-board peripherals
by loading a devicetree overlay during driver probe if the RP1
node is not already present in the DT.

The peripherals are accessed by mapping MMIO registers starting
from PCI BAR1 region.

With the overlay approach we can achieve more generic and agnostic
approach to managing this chipset, being that it is a PCI endpoint
and could possibly be reused in other hw implementations. The
presented approach is also used by Bootlin's Microchip LAN966x
patchset (see link) as well, for a similar chipset.
In this case, the inclusion tree for the DT overlay is as follow
(the arrow points to the includer):

 rp1-pci.dtso <---- rp1-common.dtsi

On the other hand, to ensure compatibility with downstream, this
driver can also work with a DT already comprising the RP1 node, so
the dynamically loaded overlay will not be used if the DT is already
fully defined.

The reason why this driver is contained in drivers/misc has
been paved by Bootlin's LAN966X driver, which first used the
overlay approach to implement non discoverable peripherals behind a
PCI bus. For RP1, the same arguments apply: it's not used as an SoC
since the driver code is not running on-chip and is not like an MFD
since it does not really need all the MFD infrastructure (shared regs,
etc.). So, for this particular use, misc has been proposed and deemed
as a good choice. For further details about that please check the links.

This driver is heavily based on downstream code from RaspberryPi
Foundation, and the original author is Phil Elwell.

66db1d3cbd PCI/pwrctrl: Add optional slot clock for PCI slots
Add the ability to enable optional slot clock into the pwrctrl driver.
This is used to enable slot clock in split-clock topologies, where the PCIe
host/controller supply and PCIe slot supply are not provided by the same
clock. The PCIe host/controller clock should be described in the controller
node as the controller clock, while the slot clock should be described in
controller bridge/slot subnode.

Example DT snippet:

  &pcicontroller {
      clocks = <&clk_dif 0>;             /* PCIe controller clock */

      pci@0,0 {
          #address-cells = <3>;
          #size-cells = <2>;
          reg = <0x0 0x0 0x0 0x0 0x0>;
          compatible = "pciclass,0604";
          device_type = "pci";
          clocks = <&clk_dif 1>;         /* PCIe slot clock */
          vpcie3v3-supply = <&reg_3p3v>;
          ranges;
      };
  };

Example clock topology:
   ____________                    ____________
  |  PCIe host |                  | PCIe slot  |
  |            |                  |            |

907a7a2e5b PCI/PM: Set up runtime PM even for devices without PCI PM
4d4c10f763 ("PCI: Explicitly put devices into D0 when initializing")
intended to put PCI devices into D0, but in doing so unintentionally
changed runtime PM initialization not to occur on devices that don't
support PCI PM.  This caused a regression in vfio-pci due to an imbalance
with its use.

Adjust the logic in pci_pm_init() so that even if PCI PM isn't supported
runtime PM is still initialized.

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)

   - Add qcom DT binding for MHI registers in IPQ5332, IPQ6018, IPQ8074
     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)
