After a PCIe Uncorrectable Error has been reported by a device with
Intel Vendor Specific Extended Capabilities and has been recovered
through a Secondary Bus Reset, its driver calls intel_vsec_pci_probe()
to rescan and reinitialize VSECs.
intel_vsec_pci_probe() invokes pcim_enable_device() and thereby adds
another devm action which calls pcim_disable_device() on driver unbind.
So once the driver unbinds, pcim_disable_device() will be called as many
times as an Uncorrectable Error occurred, plus one. This will lead to
an enable_cnt imbalance on driver unbind.
Additionally, since commit dc957ab6aa ("platform/x86/intel/vsec: Add
private data for per-device data"), a devm_kzalloc() allocation is
leaked on every Uncorrectable Error.
Avoid by splitting the VSEC rescan out of intel_vsec_pci_probe() into a
separate helper and calling that on PCIe error recovery.

This driver faults when intel vsec driver is unbound from PCI driver
interface. For example:
echo 0000:00:03.1 > /sys/bus/pci/drivers/intel_vsec/unbind
This is caused by accessing plr->dbgfs_dir after vsec_tpmi driver is
removed. Here vsec_tpmi driver is the parent. On unbind, the parent
device remove callback is called first which here will remove debugfs
interface. Hence plr->dbgfs_dir is no longer valid.
Register notifier for TPMI_CORE_EXIT and make this pointer to NULL,
so that debugfs_remove_recursive() is not called with bad plr->dbgfs_dir
pointer.
After notifier is returned the vsec_tpmi driver will call remove debugfs
by calling debugfs_remove_recursive().

In some cases a driver using services of vsec_tpmi driver requires some
processing before vsec_tpmi exits. For example a children using debugfs
can't use debugfs as this will be deleted by the vsec_tpmi driver.
This is the case when unbind using PCI driver interface. In this case
the remove callback of vsec_tpmi driver is called first, then remove
callback of its children.
Add support of blocking chain notifiers support. Notify on successful probe
and before clean up in the remove callback.

Add support for GPIO type 0x02, which controls an IR flood LED used
for face authentication on some laptops (e.g. Dell Pro Max 16 Premium).
Without this patch, the kernel logs "GPIO type 0x02 unknown; the sensor
may not work" and IR sensors paired with a flood LED cannot function.
The flood LED is registered through the LED subsystem like the existing
privacy LED, including a lookup entry to allow future consumer drivers
to find and control it via led_get().
To support multiple LEDs per INT3472 device, convert the single led
struct member to an array with a counter.

Add a con_id parameter to skl_int3472_register_led() to allow callers
to specify both the LED name suffix and lookup con_id instead of
hardcoding "privacy". This prepares for registering additional LED
types with different names.
While at it, rename the privacy LED's GPIO con_id from "privacy-led"
to "privacy" in int3472_get_con_id_and_polarity() and pass it

The memory write feature supports 32-bit writes to any TPMI offset.
However, future hardware generations may not allow writes to non-32-bit
aligned addresses due to hardware optimizations.
Since all TPMI addresses are 64-bit aligned and correspond to 64-bit
registers, enforce 32-bit alignment for write operations.

Some platforms expose PMT discovery via ACPI instead of PCI BARs. Add a
generic discovery source flag and carry ACPI discovery entries alongside
the existing PCI resource path so PMT clients can consume either.
Changes:
- Add enum intel_vsec_disc_source { _PCI, _ACPI }.
- Extend intel_vsec_platform_info and intel_vsec_device with source enum
and ACPI discovery table pointer/
- When src==ACPI, skip BAR resource setup and copy the ACPI discovery
entries into the aux device.
No user-visible behavior change yet; this only wires ACPI data through vsec
in preparation for ACPI-enumerated PMT clients.

The base_addr field in intel_vsec_platform_info was originally added to
support devices that emulate PCI VSEC capabilities in MMIO. Previously,
the code would check at registration time whether base_addr was set,
falling back to the PCI BAR if not.
Refactor this by making base_addr an explicit function parameter. This
clarifies ownership of the value and removes conditional logic from
intel_vsec_add_dev(). It also enables making intel_vsec_platform_info
const in a later patch, since the function no longer needs to write to
info->base_addr.

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware. Accordingly, a struct platform_driver should be
used by driver code to bind to that device. There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].
Overall, it is better to bind drivers to platform devices than to their

While this is not expected to alter functionality, it changes sysfs

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

- Remove stub primary (hard interrupt) handlers
A bunch of drivers implement a stub primary (hard interrupt) handler which

Merge tag 'acpi-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"This one is significantly larger than previous ACPI support pull
requests because several significant updates have coincided in it.
First, there is a routine ACPICA code update, to upstream version
20251212, but this time it covers new ACPI 6.6 material that has not
been covered yet. Among other things, it includes definitions of a few
new ACPI tables and updates of some others, like the GICv5 MADT
structures and ARM IORT IWB node definitions that are used for adding
GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
but it depends on the ACPICA changes, so it is included here). The
latter alone adds a few hundred lines of new code.
Second, there is an update of ACPI _OSC handling including a fix that
prevents failures from occurring in some corner cases due to careless
handling of _OSC error bits.
On top of that, the "system resource" ACPI device objects with the
PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
device enumeration code instead of handing them over to the legacy PNP
system driver which causes device enumeration issues to occur. Some of
those issues have been worked around in device drivers and elsewhere
and those workarounds should not be necessary any more, so they are
going away.
Moreover, the time has come to convert all "core ACPI" device drivers
that were still using struct acpi_driver objects for device binding
into proper platform drivers that use struct platform_driver for this
purpose. These updates are accompanied by some requisite core ACPI
device enumeration code changes.
Next, there are ACPI APEI updates, including changes to avoid excess
overhead in the NMI handler and in SEA on the ARM side, changes to
unify ACPI-based HW error tracing and logging, and changes to prevent
APEI code from reaching out of its allocated memory.
There are also some ACPI power management updates, mostly related to
the ACPI cpuidle support in the processor driver, suspend-to-idle
handling on systems with ACPI support and to ACPI PM of devices.
In addition to the above, bugs are fixed and the code is cleaned up in
assorted places all over.
Specifics:
- Update the ACPICA code in the kernel to upstream version 20251212
which includes the following changes:
* Add support for new ACPI table DTPR (Michal Camacho Romero)
* Release objects with acpi_ut_delete_object_desc() (Zilin Guan)

- Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs
interface code (Sumeet Pawnikar)
- Use acpi_get_local_u64_address() in the code implementing ACPI
support for PCI to evaluate _ADR instead of evaluating that object
directly (Andy Shevchenko)
- Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak
serial IRQs on that system (Ai Chao)
- Fix handling of _OSC errors in acpi_run_osc() to avoid failures on
systems where _OSC error bits are set even though the _OSC return
buffer contains acknowledged feature bits (Rafael Wysocki)
- Clean up and rearrange \_SB._OSC handling for general platform
features and USB4 features to avoid code duplication and
unnecessary memory management overhead (Rafael Wysocki)
- Make the ACPI core device enumeration code handle PNP0C01 and
PNP0C02 ("system resource") device objects directly instead of
letting the legacy PNP system driver handle them to avoid device
enumeration issues on systems where PNP0C02 is present in the _CID
list under ACPI device objects with a _HID matching a proper device
driver in Linux (Rafael Wysocki)
- Drop workarounds for the known device enumeration issues related to
_CID lists containing PNP0C02 (Rafael Wysocki)
- Drop outdated comment regarding removed function in the ACPI-based
device enumeration code (Julia Lawall)
- Make PRP0001 device matching work as expected for ACPI device
objects using it as a _HID for board development and similar
purposes (Kartik Rajput)
- Use async schedule function in acpi_scan_clear_dep_fn() to avoid
races with user space initialization on some systems (Yicong Yang)
- Add a piece of documentation explaining why binding drivers
directly to ACPI device objects is not a good idea in general and
why it is desirable to convert drivers doing so into proper
platform drivers that use struct platform_driver for device binding
(Rafael Wysocki)
- Convert multiple "core ACPI" drivers, including the NFIT ACPI
device driver, the generic ACPI button drivers, the generic ACPI
thermal zone driver, the ACPI hardware event device (HED) driver,
the ACPI EC driver, the ACPI SMBUS HC driver, the ACPI Smart
Battery Subsystem (SBS) driver, and the ACPI backlight (video)
driver to proper platform drivers that use struct platform_driver
for device binding (Rafael Wysocki)
- Use acpi_get_local_u64_address() in the ACPI backlight (video)
driver to evaluate _ADR instead of evaluating that object directly
(Andy Shevchenko)
- Convert the generic ACPI battery driver to a proper platform driver
using struct platform_driver for device binding (Rafael Wysocki)
- Fix incorrect charging status when current is zero in the generic
ACPI battery driver (Ata İlhan Köktürk)
- Use LIST_HEAD() for initializing a stack-allocated list in the
generic ACPI watchdog device driver (Can Peng)
- Rework the ACPI idle driver initialization to register it directly
from the common initialization code instead of doing that from a
CPU hotplug "online" callback and clean it up (Huisong Li, Rafael
Wysocki)
- Fix a possible NULL pointer dereference in
acpi_processor_errata_piix4() (Tuo Li)
- Make read-only array non_mmio_desc[] static const (Colin Ian King)
- Prevent the APEI GHES support code on ARM from accessing memory out
of bounds or going past the ARM processor CPER record buffer (Mauro
Carvalho Chehab)
- Prevent cper_print_fw_err() from dumping the entire memory on
systems with defective firmware (Mauro Carvalho Chehab)
- Improve ghes_notify_nmi() status check to avoid unnecessary
overhead in the NMI handler by carrying out all of the requisite
preparations and the NMI registration time (Tony Luck)
- Refactor the GHES driver by extracting common functionality into
reusable helper functions to reduce code duplication and improve
the ghes_notify_sea() status check in analogy with the previous
ghes_notify_nmi() status check improvement (Shuai Xue)
- Make ELOG and GHES log and trace consistently and support the CPER
CXL protocol analogously (Fabio De Francesco)
- Disable KASAN instrumentation in the APEI GHES driver when compile
testing with clang < 18 (Nathan Chancellor)
- Let ghes_edac be the preferred driver to load on __ZX__ and _BYO_
systems by extending the platform detection list in the APEI GHES
driver (Tony W Wang-oc)
- Clean up cppc_perf_caps and cppc_perf_ctrls structs and rename EPP
constants for clarity in the ACPI CPPC library (Sumit Gupta)"
