ACPI support fixes for 7.4-rc1
- Separate handler locking from sysfs lifetime in the ACPI platform
profile driver to avoid possible deadlocks due to sysfs accesses
during driver removal (Daniel Lezcano)
- Introduce additional locking around the evaluation of selected ACPI
control methods in a few places to work around issues related to
concurrency in AML on some platforms (Ali Ahmet Memiş)
- Address two issues reported by Sashiko in the ACPI table data sysfs
interface (Jamie Nguyen)
- Initialize parser_state.aml_end in acpi_install_method() properly to
avoid out-of-bounds accesses during control method installation (Ivan
Hu)

RISC-V updates for v7.4
- Add support for crash hotplug
- Improve user copy performance on cores with fast misaligned
accesses
- Optimize code paths involving pgtable_l{4,5}_enabled() by patching
in the return values during early boot (since these don't change
during runtime), or by specifying the return values directly in
Kconfig files (for purpose-built kernels)
- Change the PCIe bus reassignment behavior to depend on the
PCI_REASSIGN_ALL_BUS PCI flag (as ARM64 does)
- Avoid an unnecessary sstatus CSR read during context switch
- Make the sbi_ecall() macro variadic, improving code clarity
- Refactor __switch_to_vector() to prepare for upcoming vector context
switch optimizations
- Add a kselftest for vectorized user copy
- Add bounds checking on the shadow stack restore token address to
avoid it being used as an attack vector
- Fix the shadow stack and indirect branch landing pad control functions to
only update the CPU's envcfg CSR when operating on the current task
- For MIPS RISC-V systems, add support for early boot-applied errata;
and for P8700 RISC-V systems, avoid WFI usage in the kernel (since
it is buggy)
- Add the "B" RISC-V ISA extension to hwcap and hwprobe reporting
- Add support for specifying and reporting the "Zic64b" RISC-V ISA
extension, and add it to the SpacemiT K1, K3, and Sophgo SG2044 DT
files
- Require the block size of cache management operations to be
specified in DT schema validation for the RISC-V ISA extensions
Zicbom, Zicbop, and Zicboz
- Some miscellaneous fixes: fix an incorrect bitfield width in the
RVG_SYSTEM_CSR_MASK bitmask macro; make RISCV_ALTERNATIVE mandatory,
now that XIP kernel support has been removed; and remove some
unnecessary includes in kernel/smp.c

ACPI: LoongArch: Add acpi_arch_[late]_init()
LoongArch IOMMU scanning flow is similar with virtio-iommu, there is an early init phase and a late init phase. In the early init function, PCI ACS is enabled if there is IOMMU table, and the late init function is called after PCI device scanning, where IOVT table scanning function is executed. Here add acpi_arch_init() and acpi_arch_late_init() API for LoongArch: the acpi_iovt_init() function is to enable PCI ACS function if the IOMMU device exists in IOVT table; while the acpi_iovt_late_init() function is to scan IOVT table and add IOMMU devices.

TTY/Serial driver updates for 7.4-rc1
Here is the "big" set of tty and serial driver updates for 7.4-rc1.
It's not really all that big, it's been kind of quiet in this area of
the tree this development cycle in relation to other parts of the tree.
But still, included in here are:
- 8250 port updates and fixes
- 8250 driver cleanups by Jiri
- deletion of the obsolete moxa driver (making this pull request
remove more lines than added!)
- different serial driver updates for dma and other reported issues
All of these have been in linux-next with no reported problems.

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)

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)

caller, e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon
Romanovsky)
Sysfs:

(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)

if it doesn't match the one in DT, which fixes an iproc-bcma probe
failure (Semih Baskan)

before write has completed, resulting in an nvme 30 second stall
before a QID timeout and possibly other similar problems (Rickey
Bartlett)

Nedoshivin)
Marvell Aardvark PCIe controller driver:

ACPI: sysfs: Finish sysfs init when creating a table file fails
If creating the file for a table fails, acpi_tables_sysfs_init() returns without sending the uevents for the tables directories, and acpi_sysfs_init() returns before creating the hotplug and pm_profile files. Stop creating table files at that point, but finish the rest of the initialization. Skipping only the failed table would give its file name to the next table with the same signature, so reading that file would return the failed table.

ACPI: sysfs: Map only the requested range in acpi_data_show()
acpi_data_show() maps the whole data region on every read(), although it copies at most count bytes and sysfs passes at most PAGE_SIZE bytes per call. acpi_os_unmap_iomem() defers the iounmap until after an RCU grace period, so a process reading one of these files in a loop keeps many full-size mappings in flight. Map only the range being read. acpi_os_map_iomem() rounds the mapping to page boundaries, so each mapping is now at most two pages, whatever the size of the region. A malformed table can describe a region that wraps around the end of the physical address space. acpi_os_map_iomem() doesn't check for that, and its lookup of existing mappings then matches an unrelated mapping, with or without this change. Fail reads of such a region before mapping anything. Signed-off-by: Jamie Nguyen <jamien@nvidia.com> Link: https://patch.msgid.link/20261013180728.957618-1-jamien@nvidia.com Signed-off-by: Rafael J.

ACPICA: Initialize parser_state.aml_end in acpi_install_method()
In AcpiInstallMethod(), the local ParserState is stack-allocated and
only ParserState.Aml was initialized. Parser helpers called by this path
read ParserState.AmlEnd for bounds checking: AcpiPsPeekOpcode() reads it
before validating the first AML opcode, and AcpiPsGetNextPackageEnd()
reads it indirectly via AcpiPsGetNextPackageLength(). The subsequent
package-limit check also compares against ParserState.AmlEnd. Because
AmlEnd was never set, these checks operated on an uninitialized value,
which Coverity flagged as an uninitialized read (CID 1684785) and which
could lead to incorrect parser bounds decisions.
Coverity report:
*** CID 1684785: Memory - illegal accesses (UNINIT)
/src/acpica/source/components/namespace/nsxfname.c: 712 in AcpiInstallMethod()
ParserState.Aml += AcpiPsGetOpcodeSize (Opcode);
>>> CID 1684785: Memory - illegal accesses (UNINIT)
>>> Using uninitialized value "ParserState.AmlEnd" when calling
"AcpiPsGetNextPackageEnd".
ParserState.PkgEnd = AcpiPsGetNextPackageEnd (&ParserState);
Initialize ParserState.AmlEnd to the end of the table
(Buffer + Table->Length) so the parser bounds checks operate on a valid
limit.

ACPI: platform_profile: Separate handler locking from sysfs lifetime
Registration and removal currently hold profile_lock across device_unregister() and sysfs_update_group(). These operations can remove sysfs attributes and wait for their active callbacks to finish. The profile read and write callbacks acquire profile_lock themselves, so a concurrent access can deadlock: Removal/update path Active sysfs callback ------------------- --------------------- acquire profile_lock hold kernfs active reference remove a sysfs attribute wait for profile_lock wait for its active references The removal path cannot finish until the callback returns, and the callback cannot return until the removal path releases profile_lock. This applies both to per-provider device teardown and to updates of the legacy aggregate attribute group. Commit |

ACPI: utils: Add exclusive AML evaluation helpers
ACPICA drops the interpreter lock while AML waits, for example around EC accesses, so two methods can run interleaved. Some firmware relies on methods not interleaving, for instance by switching an EC page selector without taking the AML mutex that the other users of that page hold. Add acpi_evaluate_object_exclusive(), acpi_evaluate_integer_exclusive() and acpi_execute_simple_method_exclusive() which serialize the evaluation under a global mutex, for callers that are known to be affected.

Pull power management updates from Rafael Wysocki:
"This time, the most visible part are the ACPI CPPC updates from
Christian Loehle, including CPPC cpufreq driver changes, even though
updates of cpufreq drivers proper are still the largest topic group.
However, the updates of cpufreq drivers depend on the ACPI CPPC
updates, so they should really be counted together and that is well
over 1/2 of the total commit count.
Interestingly enough, almost all of the updates included here are
fixes or cleanups, with some new feature support in the amd-pstate
cpufreq driver and IPQ9650 support in the qcom-nvmem cpufreq driver.
The runtime PM documentation improvements from Brian Norris can also
be mostly regarded as fixes, but a new kunit test goes along with
them.

ACPI support updates for 7.4-rc1
- Make the core ACPI device enumeration code stop attempting to
initialize ACPI power management for devices before they are

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)

Merge tag 'acpi-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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

ACPI: PM: Add Acer Aspire A515-53G to dmi_leave_unused_power_resources_on[]
On the Acer Aspire A515-53G (Whiskey Lake + NVIDIA GeForce MX230), the
dGPU behind root port RP05 (00:1c.4) falls off the bus during boot and
is unusable until the next power cycle:
nvidia 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible
NVRM: The NVIDIA GPU 0000:02:00.0 ... has fallen off the bus
The firmware ships two SSDTs which both provide power management for
the dGPU:
- One SSDT defines \_SB.PCI0.RP05.PC01 together with
RP05._PR0/_PR2/_PR3 = { PC01 }.
- A second SSDT defines \_SB.PCI0.RP05.PCRP (_STA initially One,
_OFF calls \_SB.PCI0.HGOF, which puts the link into L2/L3 and drops
the dGPU power enable GPIO) and its own RP05._PR0/_PR2/_PR3/_S0W.
The latter fail to load:
ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.RP05._PR0], AE_ALREADY_EXISTS
As a result PCRP is not referenced by any device and
acpi_turn_off_unused_power_resources() turns it off right after the
ACPI namespace scan. This cuts power to the dGPU, but PC01 still
believes it is on, so its _ON method is a no-op when the PCI core later
tries to bring the GPU back to D0.
Windows does not turn off unused power resources, so the dGPU works
there.
Add the machine to dmi_leave_unused_power_resources_on[], like the
THUNDEROBOT ZERO which has a similar SSDT bug. With this change the
dGPU stays on the bus and the nvidia driver binds. Runtime PM of the
dGPU is unaffected, as it is handled through PC01: with no driver
bound and power/control set to auto, RP05 reaches D3cold and the GPU
comes back to D0 on resume.

ACPI: video: force native backlight on Dell OptiPlex AIO 7410 35W
The Dell OptiPlex AIO 7410 35W (board 01KP8D) declares DELL0501 in its
ACPI DSDT (status = 0x0F) even though no UART scalar board is physically
present. This causes acpi_video_get_backlight_type() to return
acpi_backlight_dell_uart, which makes i915 skip registering
intel_backlight. The dell-uart-backlight driver then times out talking
to the absent board and the probe fails, leaving the machine with zero
backlight control.
A BIOS update fixes this on some models (e.g. OptiPlex 7420, board
0914RT) by setting DELL0501 _STA to 0, but Dell has not shipped a
corrected BIOS for the 7410 even in the latest release (1.37.0,
2026-05-28).
Add a DMI quirk to force native backlight on this model so that i915
registers intel_backlight and brightness control works out of the box.
Tested on:
- OptiPlex AIO 7410 35W (01KP8D, BIOS 1.37.0) -- confirmed
acpi_backlight=native produces working intel_backlight (raw,
max=96000), DMI quirk has the same effect.
- OptiPlex AIO 7420 35W (0914RT, BIOS 1.27.0) -- DELL0501 absent in
updated BIOS, intel_backlight works natively (no regression).

ACPI: dock: Retry probing battery docks after hotplug
On a ThinkPad T480 booted with the removable battery absent, reinserting that battery can leave BAT1 missing from /sys/class/power_supply even after firmware sends an ACPI add notification. The battery dock platform device already exists, but its driver did not bind while the battery was absent. During hotplug, acpi_bus_scan() updates the ACPI device and attempts to attach it on the ACPI bus. acpi_create_platform_device() does not create another platform device because the existing physical node is still associated with the ACPI device. Consequently, the existing platform device remains unbound. Retry probing the battery dock platform device after hotplug_dock_devices() has refreshed the ACPI state. Restrict this to battery docks. If the platform device is already bound, device_initial_probe() leaves that binding in place.

ACPI: APEI: accumulate the queued flag across error sections
ghes_do_proc() walks every error section of a CPER record, and ghes_handle_arm_hw_error() walks every error-info entry of an ARM processor section. Both assign to "queued" instead of OR-ing into it, so only the last iteration counts: a later section or entry that queues no memory-failure work clears the flag an earlier one set. Instead of reassigning the variable at every time, just do an `OR`, so, if there was a single match, it will return "queued" as set. The comment above the check says "If no memory failure work is queued", which is the semantics this patch implements. I.e, only SIGBUS if there are queue was not handled at all. If we want to SIGBUS if any event was not handled/queued at all, we will need something more sophisticated. Fixes: |

PCI/ACPI: Centralize pcie_ports_native checking
If the user booted with "pcie_ports=native", we take control of the PCIe
port services unconditionally, regardless of what _OSC says.
Centralize the testing of pcie_ports_native in acpi_pci_root_create(),
where we interpret the _OSC results, so other places only have to check
host_bridge->native_X and we don't have to sprinkle tests of
pcie_ports_native everywhere.
Rather than overriding the host_bridge->native_X flags after the fact, fold
"pcie_ports=native" into the _OSC control mask we evaluate, i.e., proceed
as though the platform had granted control of the port services. That way
there is a single mechanism deciding each native_X flag, and we can report
exactly which features we are overriding _OSC for instead of just noting
that we are overriding something:
acpi PNP0A08:00: _OSC: OS forcing control ("pcie_ports=native") of [PCIeHotplug PME AER DPC]
Forcing host_bridge->native_aer also restores DPC service binding under
"pcie_ports=native", which regressed in commit

arm_mpam: add MPAM-Fb MSC firmware access support
The Arm MPAM Firmware-backed (Fb) Profile document[1] describes an alternative way of accessing the "Memory System Components" (MSC) in an MPAM enabled system. Normally the MSCs are MMIO mapped, but in some implementations this might not be possible (MSC located outside of the local socket, MSC mapped secure-only) or desirable (direct MMIO access too slow or needs to be mediated through a control processor). MPAM-fb standardises a protocol to abstract MSC accesses, building on the SCMI protocol. Add functions that do an MSC read or write access by redirecting the request through a firmware interface. For now this done via an ACPI PCC shared memory and mailbox combination. Since the protocol used is only a small subset of the full SCMI spec, and the SCMI protocol has no full ACPI support anyway, open-code the (simple) SCMI message generation, for just the fields we need.

PCI/AER: Map a raw AER Capability image field by field
struct aer_capability_regs is not the hardware layout: the embedded struct pcie_tlp_log spans 60 bytes where the Header Log it stands in for is 16, so a flat copy misplaces everything behind it. extlog_print_pcie(), ghes_handle_aer() and cxl_rch_get_aer_info() work around that by stopping at the Header Log, dropping everything past offset 44. Flit mode is never decoded either: the Flit bit and Logged TLP Size sit at offset 0x18, unread, so the Flit DWORDs at 0x38 are lost and the log prints as non-Flit. Add aer_cap_regs_unpack() to map the registers individually, taking the TLP Log layout from the Flit bit as pcie_read_tlp_log() does. Clamp the logged length: Logged TLP Size is 5 bits wide, so an untrusted value reaches 31 where dw[] holds 14 and pcie_print_tlp_log() walks header_len unbounded. Take the image little-endian, as both sources are: CPER by definition, PCIe registers on the wire. Read it with get_unaligned_le32(), since a CPER section sits wherever firmware put it, and take the two source IDs out of the Error Source Identification register by bit position rather than byte offset. cxl_rch_get_aer_info() uses readl(), so it hands back __le32. Convert all three callers. cxl_rch_get_aer_info() now reads the whole MMIO block, so size its ioremap by the hardware registers (96 bytes) rather than by sizeof(struct aer_capability_regs) (100). Shrinking the mapping is safe: the read it replaces stopped at 44 bytes.

driver core/ACPI: Introduce companion_bus_register()
The ACPI bus type does not allow drivers to be matched to devices, so the sysfs attributes related to drivers created for it are useless and their existence is confusing. Moreover, it is better to prevent drivers from being registered and looked up for a bus like that. To allow skipping the creation of those sysfs attributes and preventing driver registration and lookup for the ACPI bus type, introduce a "companion" bus type concept and add a special registration function for registering "companion" bus types, companion_bus_register(). The "drivers" directory under the ACPI bus type is still needed because there are versions of systemd that depend on it [1].

The timeout is derived from static channel properties, so compute it once when the PCC channel is set up and store the millisecond value in the mailbox client timeout field. Use the cached timeout when waiting for the OperationRegion command to complete. This keeps the timeout calculation in one place and avoids recomputing it for every command.

ACPI: PCC: Free channel on OpRegion deactivation
ACPICA calls the address space setup callback with
ACPI_REGION_DEACTIVATE when a PCC OperationRegion is torn down.
The PCC setup callback currently allocates a fresh pcc_data and requests
the mailbox channel before looking at the function argument. If ACPICA
deactivates a region, this can leave the existing region context and
mailbox channel unreleased, and may also request a channel during
teardown.
Handle ACPI_REGION_DEACTIVATE before allocation. Free the PCC mailbox
channel, release the region context and clear the context pointer.

ACPI: PCC: Preserve shared memory signature in OpRegion handler
ACPI 6.3 introduced PCC OperationRegions. Section 5.5.2.4.7.3, "Declaring message fields within a PCC OperationRegion", states that, for all PCC subspace types, the PCC Operation Region pertains to the region of PCC subspace that succeeds the PCC signature. Its length therefore excludes the 4-byte signature. The PCC address space handler currently copies the OperationRegion buffer to and from the start of the shared memory. This overwrites or exposes the platform-populated signature and omits the final four bytes of the OperationRegion.

ACPICA: Fix PCC OperationRegion command offsets
ACPI 6.3, section 5.5.2.4.7.3, states that the PCC Operation
Region is associated with the region of shared memory that follows the
PCC signature.
The generic and extended PCC shared memory layouts include the 4-byte
signature at offset 0, so their raw shared memory COMMAND fields are at
offsets 4 and 12 respectively. Since AML field offsets for the PCC
OperationRegion are relative to the region after that signature, ACPICA
must look for those COMMAND fields at OperationRegion offsets 0 and 8.
Adjust the generic and master subspace command checks to use those
OperationRegion-relative offsets. Otherwise writes to the COMMAND field
can fail to invoke the PCC address space handler at the offset described
by the PCC OperationRegion definition.

ACPICA: Fix memory leak in acpi_ds_create_field()
acpi_ds_create_field() allocates internal_pcc_buffer for operation
regions in the PCC address space.
The function runs once per field, so a second field on the
same region overwrites the pointer and orphans the previous buffer.
The matching ACPI_FREE() in acpi_ut_delete_internal_obj() only ever sees
the last one.
An arm64 platform whose SSDT declares regions with multiple fields each
leaks two buffers at boot, as detected by kmemleak:
unreferenced object 0xffff000051e65400 (size 192):
comm "swapper/0", pid 1, jiffies 4294668436
backtrace (crc 0):
__kmalloc_noprof
acpi_ds_create_field
acpi_ds_load2_end_op
acpi_ds_exec_end_op
acpi_ps_parse_loop
acpi_ps_parse_aml
acpi_ns_load_table
acpi_load_tables
acpi_init
Do not allocate a region if it was previously allocated before,
preserving the current design, but, not leaking memory.
