Pull CXL updates from Dave Jiang:
"The headline item is the first part of support for Dynamic Capacity
Devices (DCD). It covers flagging DCD support in the mailbox, reading
the dynamic capacity configuration from the device, gathering DSMAS
data for the DCD partitions, and configuring the dynamic capacity
interrupts. It also adds a documentation update and a cleanup that
enforces partition ordering. DCD is not enabled yet with these code
changes. Patches are applied to reduce the whole set in order to
relief the burden of very large patch set review.
Zero sized HDM decoders are now allowed, along with cxl_test support
for them. There is also a set of decoder hardening patches for switch
decoder enumeration. Latency calculations now account for link width
and use consistent units. The GPF timeout programming has been
reworked. The pull also has a number of misc patches.
A large number of bug fixes against pre-existing issues make up the
rest of the pull. Many of these were flagged by review of patches
posted to the mailing list by sashiko.
Also adding Richard Cheng as a reviewer (R) to the CXL sub-system"

git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Set supported_speeds in set_pcie_port_type() so sparc64 and
powerpc, which call it via of_create_pci_dev() instead of the usual
pci_setup_device(), correctly set the supported PCIe link speeds
(Stian Halseth)
- When pcie_set_mps() changes MPS, update the value in the saved
state so a subsequent restore doesn't restore an invalid value
(Niklas Cassel)
- Skip Target Speed quirk on clamped ports with no link (Maciej W.
Rozycki)
Driver binding:
- Assume control of portdrv-related features only when portdrv is
enabled, since we can't use them without portdrv (Kuppuswamy
Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
(Kuppuswamy Sathyanarayanan)
Error handling:
- Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
mention a device that no longer exists (Priyank Rathod)
- Fix aer_process_err_devices() leak when a device is recorded as an
error source purely by being mentioned in the Root Port Error
Source and the device is inaccessible or logged only masked errors
(Priyank Rathod)
ASPM:
- Disable ASPM when drivers request that, even if the OS doesn't own
ASPM; otherwise drivers do it on their own, which is worse (Ilpo
Järvinen)
Power management:
- Align hibernate poweroff flow with suspend flow for bridges so they
can be powered down at hibernate as they are for suspend (Mario
Limonciello)
- Restore BARs after powering up during enumeration to fix a
regression on devices that don't preserve state in D3hot (Keng-Yu
Lin)
- Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting
them in D3hot takes down the whole switch (Imre Kaloz)
Power control:
- Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
Elder)
- Add DT documentation and pwrctrl driver support for TC9563 embedded
GPIO controller (Lorenzo Bianconi)
- Switch the tc9563 per-port reset to use the GPIO descriptor API
instead of direct regmap accesses (Lorenzo Bianconi)
- Only destroy devices created by pwrctrl core, so that when removing
a PCIe controller driver that uses pwrctrl, we don't remove devices
populated by another mechanism (Shawn Lin)
- Power off child devices on power-on failure (Lorenzo Bianconi)
PCIe native device hotplug:
- Make the 'pciehp_poll_mode' parameter read-only to prevent changes
via sysfs, which can cause errors when unbinding (Runyu Xiao)
Virtualization:
- Read SR-IOV VF Revision ID and Subsystem ID from VF instead of
assuming they're the same as VF 0; they may differ (Logan Odell)
- Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)
Peer-to-peer DMA:
- Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
bridges to allowlist (LeoLiu-oc)
- Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)
- Add Intel Haswell client host bridge to allowlist (Scott Lee)
- Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)
- Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
unmapping a BAR if registering another fails and (b) use after free
of p2p_pgmap (Leon Romanovsky)
- Wait for RCU readers before freeing state to avoid use-after-free
of pdev->p2pdma (Leon Romanovsky)
- Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
Romanovsky)
- Safely terminate ACS redirect lists to avoid out-of-bounds access
to the buffer (Leon Romanovsky)
- Silence 'Host bridge not in P2PDMA whitelist' warnings unless
caller, e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon
Romanovsky)
Sysfs:
- Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes
when Device Name _DSM fails, not -1, which is interpreted as -EPERM
(Krzysztof Wilczyński)
- Return valid sysfs 'acpi_index' attribute even if the Device Name
_DSM returned an invalid 'label' (Krzysztof Wilczyński)
- Expose sysfs 'acpi_index' and 'label' based on whether the Device
Name _DSM returns valid data, not merely whether the _DSM is
implemented (Krzysztof Wilczyński)
- Avoid out-of-bounds reads of the label returned by the Device Name
_DSM, which is in UTF-16 characters, not bytes (Krzysztof
Wilczyński)
- Reject unaligned resource I/O port accesses, which can oops on
arm64 (Deepanshu Kartikey)
Endpoint framework:
- Pass the correct physical and virtual endpoint function numbers
when setting translation of inbound memory windows (Koichiro Den)
- Make embedded doorbell IRQ non-shared, since currently only the
first EPF can allocate doorbells (Koichiro Den)
- MSI doorbells currently target the first EPF attached to an EPC;
let other EPFs try the embedded doorbell instead of failing when
they can't use the MSI doorbell (Koichiro Den)
- Serialize scan of vNTB virtual PCI bus with other PCI topology
changes (Koichiro Den)
- Manage vNTB lifetimes to avoid leaking virtual devices and buses
and allow removal (Koichiro Den)
- Track vNTB link state from both sides so both see the same
effective link state (Koichiro Den)
- Configure vNTB MSI-X when supported to avoid IOMMU faults and
failure to deliver doorbell interrupts on RC (Koichiro Den)
APM X-Gene PCIe controller driver:
- Use devm for clocks so they're automatically disabled, unprepared,
and released if errors happen during probe (Yuho Choi)
ASPEED PCIe controller driver:
- Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
Zhenlong)
Broadcom iProc PCIe controller driver:
- Expose devm_pci_alloc_host_bridge_release() so drivers can share a
devm release function even if they don't need the device tree
parsing done by devm_pci_alloc_host_bridge() (Bjorn Helgaas)
- Request only the memory window from BCMA Enumeration ROM and warn
if it doesn't match the one in DT, which fixes an iproc-bcma probe
failure (Semih Baskan)
Broadcom STB PCIe controller driver:
- Replace bool properties for each SoC configuration with a u32
bitvector and a BFLAG() helper (Jim Quinlan)
- Use a similar BQUIRK() helper to test various SoC quirks (Jim
Quinlan)
Cadence PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Return error (not success) from cdns_plat_pcie_probe() if
pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir
Oltean)
- Correct the driver data pointer usage; previously .probe() stored
'struct cdns_plat_pcie *', but .shutdown() used the pointer as
'struct cdns_pcie *', resulting in accessing garbage (Linmao Li)
ESWIN PCIe controller driver:
- Publish the platform driver MODULE_DEVICE_TABLE so the driver can
be autoloaded when built as a module (Pengpeng Hou)
Freescale i.MX6 PCIe controller driver:
- Fix resource and pwrctrl device leaks .probe() (Zhijian Han)
- Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
default 120 to 140 (Richard Zhu)
- Use dev_err_probe() in host init error path to silence
-EPROBE_DEFER messages (Alexander Stein)
- Avoid dereferencing NULL clock names when 'clocks' includes more
phandles than 'clock-names' has names (Rudi Heitbaum)
- Add suspend_poweroff flag so platforms like i.MX that power off RC
controllers during suspend can enter L2 so endpoints can get
PME_Turn_Off notifications before power loss (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
controllers on LX2160A (Vincent Jardin)
Intel VMD host bridge driver:
- Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
before write has completed, resulting in an nvme 30 second stall
before a QID timeout and possibly other similar problems (Rickey
Bartlett)
- Flush DMA writes before handling MSI on Arrow Lake (Vladimir
Nedoshivin)
Marvell Aardvark PCIe controller driver:
- Disable PHY on probe failures (Myeonghun Pak)
Marvell MVEBU PCIe controller driver:
- Refcount child OF nodes during .probe() to make a concurrent OF
overlay removal safe (Krzysztof Kozlowski)
MediaTek PCIe controller driver:
- Find INTx DT property by 'interrupt-controller' name instead of
assuming it's the first child node (Zhengping Zhang)
MediaTek PCIe Gen3 controller driver:
- Fix a 64-bit type truncation in mtk_pcie_set_trans_table() to avoid
issues with windows above or larger than 4GB (Sreeraj S Kurup)
NVIDIA Tegra264 PCIe controller driver:
- Fix the Link Capabilities offset so we read the correct register
(Bjorn Helgaas)
Qualcomm PCIe controller driver:
- Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
resets used by downstream devices like USB controllers (Christopher
Obbard)
- Block accesses to downstream devices on link down to reduce a storm
of Completion Timeout AER interrupts (Qiang Yu)
- Skip system suspend/resume for firmware-managed PCIe, where
firmware manages clocks, regulators, resets, etc (Mrinmay Sarkar)
- Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
(Manivannan Sadhasivam)
- Deinitialize endpoint on remove (Guangshuo Li)
- Treat Root Port error recovery as successful even if link doesn't
come up after reset because the device was hot-unplugged (Konrad
Dybcio)
- Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
indicating an external MSI controller (Ayiluri Naga Rashmi)
Renesas R-Car PCIe controller driver:
- Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
Vasut)
- Support PERST# via reset subsystem as well as the existing GPIO
support to prepare for R-Car Gen5 SoCs (Marek Vasut)
- Add DT and driver support for the R-Car Gen 5 X5H (R8A78000) PCIe
Gen 4 core (Marek Vasut)
- Add Application/Local register reset DT description and driver
support for both host and endpoint mode (Marek Vasut)
- Add PM ops so controller works after suspend/resume (Marek Vasut)
Renesas RZ/G3S PCIe controller driver:

Prabhakar)
- Add RZ/G3L (R9A08G046) DT and driver support (Biju Das)
Rockchip PCIe controller driver:
- Limit host and endpoint controllers to 2.5 GT/s since 5.0 GT/s is
unsafe per Rockchip (Geraldo Nascimento)
Synopsys DesignWare PCIe controller driver:
- Set DMA_BYPASS bit in outbound IATU CTRL2 register to avoid data
corruption if the iATU translates DMA engine transactions (Sumit
Kumar)
- Use FIELD_PREP() to remove need for *_SHIFT definitions (Hans
Zhang)
TI DRA7xx PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Fix optional clock leak when .probe() fails by using
devm_clk_get_optional_enabled() (Felix Gu)
TI Keystone PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)

Pull VFIO updates from Alex Williamson:
- Fix missing selftest <libgen.h> include for basename() to support
non-glibc builds (Hisam Mehboob)
- Add vfio selftest documentation covering the libvfio helper library
and guidance for developers to aid in adding and understanding the
framework (David Matlack)
- Fix vfio cdev open path to prevent a second open from clobbering the
vf_token or clearing the KVM reference. Add a selftest to avoid
future recurrences (Alex Williamson)
- Extend vfio selftest mix_and_match timeouts, in particular to account
for systems where generated faults can induce heavy SMM load,
delaying internal timeouts. Also extend timeout for execution via
runner to account for various tests exceeding default 45s timeout
(Alex Williamson)
- Add tracking for non-reserved mappings into a vfio_dma object in
order to optimize the tear-down paths where per-page tests can be
entirely skipped. This resolves a soft lockup for large memory GPUs
(Samuel Crossley)
- Add vfio selftest driver for mlx5, providing another target for
exercising DMA and interrupts against a physical device (Jason
Gunthorpe)
- Hardening against read-only region promotion, preserving vm_pgoff for
unmap_mapping_range(), and reject non-shared MMIO mmaps as necessary
through vfio-platform, vfio-fsl-mc, and vfio-cdx. These prevent
future issues, though none are currently reachable (Abdifatah Suruur)

erroneously left in place when generalizing 8-byte io accesses (Li
RongQing)
- Fix missed RCU drain on module exit (Jiale Yao)
- Fix off-by-one boundary check in migration support within the mlx5
vfio-pci variant driver (Seongjun Hong)

variant drivers to freely create their own conventions and enabling a
future Rust-based variant driver. A DRM topic branch is also merged
in support of this effort, modifying the vga arbiter API to more
cleanly remove the drvdata dependency (Simon Song)
- Fix hisi_acc vfio-pci variant driver to avoid NULL pointer accesses
when bound to unsupported devices and also disabling migration
support when running on 64K host page size due to BAR mapping
constraints (Longfang Liu)

Pull ACPI support updates from Rafael Wysocki:
"The most significant change here is the rework of the core ACPI device
enumeration code to avoid initializing ACPI power management
prematurely for devices with unmet dependencies. This essentially is a
problem fix, but it requires taking PCI device enumeration ordering
into account among other things, so it is far from straightforward.
There was an attempt to do this in the 7.3 time frame that had to be
reverted, so this time it is done much more carefully.
There is also an ACPI thermal control update rearranging the code to
register thermal class cooling devices under specific parents, which
is visible in sysfs. This helps to figure out what is represented by
those devices much more easily, but it also allows the binding of
cooling devices to trip points in thermal zones to be adjusted so it
need not rely on specific cooling device data usage in thermal
drivers.
From the number of commits perspective, the most visible part is the
one replacing acpi_get_first_physical_node() with
acpi_bus_get_primary_device() everywhere and dropping the former that
was inherently racy and generally unsafe to use. Fortunately, the
maintainers involved responded timely and all of that could be done
within one development cycle.
Another quite visible part is Dave Jiang's series fixing multiple
issues reported by Sashiko in the ACPI APEI support code with a PCI
AER improvement on top. It took several iterations of this to make
Sashiko happy and the code in question should be much more robust
going forward.
One other thing worth mentioning separately is that the ACPI bus type
is now going to be registered as a "companion" one and it will not be
possible to register a driver binding directly to a struct
acpi_device. All of the existing users of those drivers in the tree
were converted to platform drivers in the previous cycles, so this is
just a final step in a longer journey.
Apart from the above, there are many fixes, mostly in drivers, with a
noticeable exception of a fix in the code binding devices to their
ACPI companions, new IOVT IOMMU support in ACPICA, new _Ixx object
support for suspend-to-idle on x86, multiple new quirks, mostly
related to unused ACPI power resources and backlight handling, and
assorted cleanups.
Specifics:
- Make the core ACPI device enumeration code stop attempting to
initialize ACPI power management for devices before they are known
to be present and functional (Rafael Wysocki)
- Simplify and clean up the core ACPI device enumeration code on top
of the previous adjustment and reduce debug noise coming from it
(Rafael Wysocki)
- Fix locking in the code binding devices to their ACPI companions,
prevent it from replacing a valid ACPI companion pointer with NULL
incidentally, improve its messaging (including debug noise
reduction), and reduce its overhead by making it skip the cases in
which no ACPI companion may exist early (Rafael Wysocki)
- Reduce runtime memory footprint of struct acpi_device by
rearranging fields in it (Andy Shevchenko)
- Update the driver core to allow bus types without drivers to be
registered as "companion bus types" without driver-related sysfs
attributes and register the ACPI bus type as a companion one
(Rafael Wysocki)
- Use strscpy() instead of strcpy() in the ACPI sysfs interface
(Ruslan Vagner)
- Remove __meminitdata from hmat_adist_nb declaration preserving it
even when CONFIG_MEMORY_HOTPLUG is not set to prevent notifier
chain corruption in some cases (Alejandro Lucero)
- Prevent a NULL pointer dereference when attempting to read the
table length after a mapping bookkeeping failure during an initrd
override invocation with permanent table mappings enabled (Slavin
Liu)
- Use for_each_populated_zone() in get_node_num() in the MRRM table
pareser (Sang-Heon Jeon)
- Use vsnprintf() in acpi_os_vprintf() to prevent memory corruption
resulting from overly long diagnostic messages that may not fit
into a static buffer used by ACPICA and may be produced by a
malformed ACPI table (Vlatko Kosturjak)
- Ignore leading root scope prefix in string _UID match to allow AMD
IOMMU matching to work as expected in some cases (Mario
Limonciello)
- Adjust message printing macros for ACPI objects to use dev_fmt()
for more consistency with the analogous dev_*() macros (Rafael
Wysocki)
- Add _Ixx GPE wake indicator support to the x86 suspend-to-idle
handling code (Saranya Gopal)
- Clear driver_data before free in the ACPI PCI Link driver to
prevent a dangling pointer from being used later (Jiale Yao)
- Accumulate the queued flag across error sections of a CPER record
in ghes_do_proc() to prevent it from being cleared by a later
section or entry that does not queue memory-failure work (Breno
Leitao)
- Map a raw PCI AER Capability image field by field to prevent
information loss from occurring while processing it (Dave Jiang)
- Update a stale driver source reference in the ACPI APEI EINJ driver
documentation (Prabhakar Pujeri)
- Reject CPER records with an out-of-range error_data_length or an
error status block length wrapping a u32 in the EFI CPER driver
(Dave Jiang)
- Address multiple assorted issues in the ACPI extlog driver (Dave
Jiang)
- Address two issues related to CXL in the ACPI APEI GHES driver
(Dave Jiang)
- Read only validated fields in cper_mem_err_pack() (Dave Jiang)
- Validate memory error section length before payload access, prevent
writes past array bounds from occurring and sanitize software
metadata in the ACPI APEI GHES driver (Dave Jiang)
- Make cxl_cper_handle_prot_err() static (Dave Jiang)
- Add IOVT IOMMU support to ACPICA (Bibo Mao)
- Fix PCC OperationRegion command offsets in ACPICA (Sudeep Holla)
- Fix memory leak in acpi_ds_create_field() related to the handling
of internal_pcc_buffer allocations (Breno Leitao)
- Fix memory leak due to leftover devm_kcalloc() argument in the ACPI
fan driver (Rafael Wysocki)
- Fix backlight unregistration ordering in the ACPI video bus device
driver (Rafael Wysocki)
- Update the thermal core to allow the registration of thermal class
cooling devices under specific parents and convert the ACPI fan,
ACPI processor, and ACPI video bus device drivers to do so (Rafael
Wysocki)
- Adjust the ACPI thermal zone driver to use thermal class cooling
device parent information for binding cooling devices to trip
points in thermal zones (Rafael Wysocki)
- Use cooling device data that is a better match for a given driver
instead of a struct acpi_device pointer that had to be used for
this purpose previously in the ACPI fan and processor drivers
(Rafael Wysocki)
- Fix acpi_thermal_guess_offset() in the ACPI thermal zone driver for
thermal zone devices with a 273.0°K offset (Hans de Goede)
- Define a free for ACPI objects allocated by ACPICA helpers and use
it to simplify AML error handling in the ACPI fan driver (Rafael
Wysocki)
- Switch over the users of acpi_get_first_physical_node(), that was
inherently racy and therefore not really safe to use, to use its
replacement acpi_bus_get_primary_device(), and eliminate the former
(Rafael Wysocki)
- Add !CONFIG_ACPI stubs for acpi_find_child_device() and
acpi_device_uid() (Mario Limonciello and Robin Murphy)

RZ09-0310 to the ACPI button driver (Ian Gallagher)

driver (Chitransh Mandhaniya and Dirga Yuza)
- Fix the shared memory signature handling in the ACPI PCC address
space handler, free the PCC mailbox channel on operation region
deactivation, and avoid unnecessary repeated computations of the
PCC operation region command timeout (Sudeep Holla)
- Fix a log message typo in the ACPI NUMA support code (Hemanth
Selam)
- Zero-initialize capability query result in the ACPI Platform
Firmware Runtime Update and Telemetry driver to avoid disclosure of
kernel stack data to user space (Karl Mehltretter)
- Replace the remaining built-in/module check for CONFIG_ACPI_WMI in
a header file with IS_ENABLED() macro (Lalit Shankar Chowdhury)
- Retry probing battery docks after hotplug in the ACPI docking
station driver to avoid missing ACPI add notifications (Vibhor
Goel)

Pull irq updates from Thomas Gleixner:
"Updates for the generic interrupt subsystem:
- Skip programming of MSI/MSI-X related data while a PCI channel is
offline (Link is down) in the error recovery code path. Accessing
an offline channel results in a BUS error which affects the
underlying Root Port.
Check for pci_channel_offline() and if true avoid the writes and
just cache the modifications which are subsequently applied when
the Link has recovered.
- Prevent a stack UAF when a faulting interrupt thread exits. On X86
the crash causes the stack to be discarded, which contains the
callback head for the exit task_work to run the destructor. If the
stack is clobbered before the destructor runs, then the indirect
call of the task work function ends up in a random place. Move the
callback head into the interrupt action to prevent that.
- Prevent an UAF in the interrupt thread exit code which can happen
when a faulting interrupt thread exits and races with a concurrent
free_irq() by synchronizing free_irq() against thread exit.
- Ensure that interrupt context accounting is accurate on interrupt
return when checking for soft interrupt invocation.
The code removed the hard interrupt context prematurely so that the
subsequent code appeared to be in task context according to the
preempt counter. That confuses ftrace, perf and K*SAN which get
their recording context wrong. On Preempt-RT this can result in
misbehaviour when BPF programs are attached to the affected region.
Cure it by preserving the hard interrupt count up to the point
where soft interrupts are actually invoked and switch directly to
soft interrupt processing right there. That avoids the intermediate
"in task context" state.
- The usual small fixes and improvements"

pci_pwrctrl_power_on_device() recursively powers on the child nodes of a
device before powering on the device itself. If powering on a child fails
(e.g. returning -EPROBE_DEFER), the function returned immediately, leaving
the sibling children that were already powered on in the same loop
iteration enabled.
Since probe deferral is a standard boot path, this leads to unbounded
regulator and clock enable increments across retries. The error path in
pci_pwrctrl_power_on_devices() only powers off the top-level children
processed before the failing one and explicitly stops at it, so it can
never clean up the siblings leaked deeper in the failed subtree.
Power off the sibling children that were successfully powered on before a
child fails, and power off all children if the device's own power_on()
fails after its children were already enabled. Switch to a manual child
iterator so the failing node can be tracked and its reference released in
the error path.

pci_pwrctrl_create_device() only creates platform devices for OF nodes
that pci_pwrctrl_is_required() accepts, but pci_pwrctrl_destroy_device()
unregisters the platform device of every available child node without
that check.
Nodes under a PCI host controller that are not pwrctrl devices may have
been populated by another mechanism. Destroying them here would tear down
devices owned by other code.
Mirror the check done at creation time so that only devices created by the
pwrctrl core are removed.
