Since commit 5aa9d943e9b6 ("ACPI: video: Don't enable fallback path for
creating ACPI backlight by default"), the delayed registering of
acpi_video# backlight devices has been disabled by default.
The few bugreports where this option was used as a workaround were all
cases where the GPU driver did not call acpi_video_register_backlight()
and the workaround was to pass video.register_backlight_delay=1.
With the recent "ACPI: video: Make acpi_backlight=video work independent
from GPU driver" changes acpi_backlight=video can be used to achieve
the same result. So there is no need for the register_backlight_delay
option + code anymore.

Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.
This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3). Note that the spec requires there be at
least one interrupt, so use a union to keep space allocated for this.
The only binary change in .text and .data sections is some rearrangement
by the compiler of acpi_dm_address_common(), but appears to be harmless.

ACPICA commit f4a3afd78c28dede0907f47951f0b73c9a776d4e
The "Source" array is actually a dynamically sized array, but it
is defined as a fixed-size 4 byte array. This results in tripping
both compile-time and run-time bounds checkers (e.g. via either
__builtin_object_size() or -fsanitize=bounds).
To retain the padding, create a union with an unused Pad variable of
size 4, and redefine Source as a proper flexible array member.

ACPICA commit e73b227e8e475c20cc394f237ea35d592fdf9ec3
In order to enable using -fstrict-flex-arrays with GCC and Clang in the
Linux kernel, each trailing dynamically sized array must be defined as
proper C99 "flexible array members" (FAM). Unfortunately, ACPICA has a
bunch of technical debt, dating back to before even the GNU extension of
0-length arrays, meaning the code base has many 1-element and 0-length
arrays defined at the end of structures that should actually be FAMs.
One limitation of the C99 FAM specification is the accidental requirement
that they cannot be in unions or alone in structs. There is no real-world
reason for this, though, and, actually, the existing GNU extension
permits this for 0-length arrays (which get treated as FAMs).
Add the ACPI_FLEX_ARRAY() helper macro to work around this requirement
so that FAMs can be defined in unions or alone in structs. Since this
behavior still depends on GNU extensions, keep the macro specific to GCC
(and Clang) builds. In this way, MSVC will continue to use 0-length
arrays (since it does not support the union work-around). When MSVC
grows support for this in the future, the macro can be updated.

not. This appears to have been a bug. After this change, there is a binary
difference in acpi_dm_dump_nfit() since the size of the structure now has
the correct size, as the prior result was including the trailing U32:

Like many tables, this is a header followed by multiple subtables of
varying self-identifying types, and ACPICA does not normally add a field
for the subtables, instead relying on pointer arithmetic past the end of
the first header struct, since indexing a flexible array member is
meaningless for variable-length entries. If we really wanted a field for
this, we could use a u8 flexible array member, but it contradicts the
current style. Using void *, however, is categorically wrong, as ACPI
tables never contain native C-language pointers.

x86 ACPI boards which ship with only Android as their factory image usually
have pretty broken ACPI tables, relying on everything being hardcoded in
the factory kernel image and often disabling parts of the ACPI enumeration
kernel code to avoid the broken tables causing issues.
Part of this broken ACPI code is that sometimes these boards have _AEI
ACPI GPIO event handlers which are broken.
So far this has been dealt with in the platform/x86/x86-android-tablets.c
module, which contains various workarounds for these devices, by it calling
acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to
disable the handlers.
But in some cases this is too late, if the handlers are of the edge type
then gpiolib-acpi.c's code will already have run them at boot.
This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion",
making them unavailable for drivers which actually need them.
Boards with these broken ACPI tables are already listed in
drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration().
Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers()
helper, this re-uses the DMI-ids rather then having to duplicate the same
DMI table in gpiolib-acpi.c .
Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing
boards with troublesome ACPI gpio event handlers, so that the current
acpi_gpiochip_free_interrupts() hack can be removed from
x86-android-tablets.c .

I guess the Intel Compiler support is broken, and nobody is caring
about it.
Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is
deprecated:
$ icc -v
icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is
deprecated and will be removed from product release in the second half
of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended
compiler moving forward. Please transition to use this compiler. Use
'-diag-disable=10441' to disable this message.
icc version 2021.7.0 (gcc version 12.1.0 compatibility)

Merge tag 'pci-v6.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Rework portdrv shutdown so it disables interrupts but doesn't
disable bus mastering, which leads to hangs on Loongson LS7A
- Add mechanism to prevent Max_Read_Request_Size (MRRS) increases,
again to avoid hardware issues on Loongson LS7A (and likely other
devices based on DesignWare IP)
- Ignore devices with a firmware (DT or ACPI) node that says the
device is disabled
Resource management:
- Distribute spare resources to unconfigured hotplug bridges at
boot-time (not just when hot-adding such a bridge), which makes
hot-adding devices to docks work better. Tried this in v6.1 but had
to revert for regressions, so try again
- Fix root bus issue that dropped resources that happened to end
at 0, e.g., [bus 00]
PCI device hotplug:
- Remove device locking when marking device as disconnected so this
doesn't have to wait for concurrent driver bind/unbind to complete
- Quirk more Qualcomm bridges that don't fully implement the PCIe
Slot Status 'Command Completed' bit
Power management:
- Account for _S0W of the target bridge in acpi_pci_bridge_d3() so we
don't miss hot-add notifications for USB4 docks, Thunderbolt, etc
Reset:
- Observe delay after reset, e.g., resuming from system sleep,
regardless of whether a bridge can suspend to D3cold at runtime
- Wait for secondary bus to become ready after a bridge reset
Virtualization:
- Avoid FLR on some AMD FCH AHCI adapters where it doesn't work
- Allow independent IOMMU groups for some Wangxun NICs that prevent
peer-to-peer transactions but don't advertise an ACS Capability
Error handling:
- Configure End-to-End-CRC (ECRC) only if Linux owns the AER
Capability
- Remove redundant Device Control Error Reporting Enable in the AER
service driver since this is already done for all devices during
enumeration
ASPM:
- Add pci_enable_link_state() interface to allow drivers to enable
ASPM link state
Endpoint framework:
- Move dra7xx and tegra194 linkup processing from hard IRQ to
threaded IRQ handler
- Add a separate lock for endpoint controller list of endpoint
function drivers to prevent deadlock in callbacks
- Pass events from endpoint controller to endpoint function drivers
via callbacks instead of notifiers
Synopsys DesignWare eDMA controller driver (acked by Vinod):
- Fix CPU vs PCI address issues
- Fix source vs destination address issues
- Fix issues with interleaved transfer semantics
- Fix channel count initialization issue (issue still exists in
several other drivers)
- Clean up and improve debugfs usage so it will work on platforms
with several eDMA devices
Baikal T-1 PCIe controller driver:
- Set a 64-bit DMA mask
Freescale i.MX6 PCIe controller driver:
- Add i.MX8MM, i.MX8MQ, i.MX8MP endpoint mode DT binding and driver
support
Intel VMD host bridge driver:
- Add quirk to configure PCIe ASPM and LTR. This is normally done by
BIOS, and will be for future products
Marvell MVEBU PCIe controller driver:
- Mark this driver as broken in Kconfig since bugs prevent its daily
usage
MediaTek MT7621 PCIe controller driver:
- Delay PHY port initialization to improve boot reliability for ZBT
WE1326, ZBT WF3526-P, and some Netgear models
Qualcomm PCIe controller driver:
- Add MSM8998 DT compatible string
- Unify MSM8996 and MSM8998 clock orderings
- Add SM8350 DT binding and driver support
- Add IPQ8074 Gen3 DT binding and driver support
- Correct qcom,perst-regs in DT binding
- Add qcom_pcie_host_deinit() so the PHY is powered off and
regulators and clocks are disabled on late host-init errors
Socionext UniPhier Pro5 controller driver:
- Clean up uniphier-ep reg, clocks, resets, and their names in DT
binding
Synopsys DesignWare PCIe controller driver:
- Restrict coherent DMA mask to 32 bits for MSI, but allow controller
drivers to set 64-bit streaming DMA mask
- Add eDMA engine support in both Root Port and Endpoint controllers
Miscellaneous:
- Remove MODULE_LICENSE from boolean drivers so they don't look like
modules so modprobe can complain about them"

Including:
- Consolidate iommu_map/unmap functions. There have been
blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.
- Retire the detach_dev() call-back in iommu_ops
- Arm SMMU updates from Will:
- Device-tree binding updates:
* Cater for three power domains on SM6375
* Document existing compatible strings for Qualcomm SoCs
* Tighten up clocks description for platform-specific compatible strings

- Intel VT-d updates from Lu Baolu:

Pluton is an integrated security processor present in some recent Ryzen
parts. If it's enabled, it presents two devices - an MSFT0101 ACPI device
that's broadly an implementation of a Command Response Buffer TPM2, and an
MSFT0200 ACPI device whose functionality I haven't examined in detail yet.
This patch only attempts to add support for the TPM device.
There's a few things that need to be handled here. The first is that the
TPM2 ACPI table uses a previously undefined start method identifier. The
table format appears to include 16 bytes of startup data, which corresponds
to one 64-bit address for a start message and one 64-bit address for a
completion response. The second is that the ACPI tables on the Thinkpad Z13
I'm testing this on don't define any memory windows in _CRS (or, more
accurately, there are two empty memory windows). This check doesn't seem
strictly necessary, so I've skipped that.
Finally, it seems like chip needs to be explicitly asked to transition into
ready status on every command. Failing to do this means that if two
commands are sent in succession without an idle/ready transition in
between, everything will appear to work fine but the response is simply the
original command. I'm working without any docs here, so I'm not sure if
this is actually the required behaviour or if I'm missing something
somewhere else, but doing this results in the chip working reliably.

Add support for setting and querying EPP preferences to the generic

and use these values.
Downstream drivers that want to use the new symbols cppc_get_epp_caps
and cppc_set_epp_perf for querying and setting EPP preferences will need
to call cppc_set_epp_perf to enable the EPP function firstly.

A new field, which indicates the size of the remapping hardware register
set for this remapping unit, is introduced in the DMA-remapping hardware
unit definition (DRHD) structure with the VT-d Spec 4.0. With this
information, SW doesn't need to 'guess' the size of the register set
anymore.
Update the struct acpi_dmar_hardware_unit to reflect the field. Store the
size of the register set in struct dmar_drhd_unit for each dmar device.
The 'size' information is ResvZ for the old BIOS and platforms. Fall back
to the old guessing method. There is nothing changed.

It is questionable to allow a PCI bridge to go into D3 if it has _S0W
returning D2 or a shallower power state, so modify acpi_pci_bridge_d3(() to
always take the return value of _S0W for the target bridge into account.
That is, make it return 'false' if _S0W returns D2 or a shallower power
state for the target bridge regardless of its ancestor Root Port
properties. Of course, this also causes 'false' to be returned if the Root
Port itself is the target and its _S0W returns D2 or a shallower power
state.
However, still allow bridges without _S0W that are power-manageable via
ACPI to enter D3 to retain the current code behavior in that case.
This fixes problems where a hotplug notification is missed because a bridge
is in D3. That means hot-added devices such as USB4 docks (and the devices
they contain) and Thunderbolt 3 devices may not work.

The Dell Latitude E6430 both with and without the optional NVidia dGPU
has a bug in its ACPI tables which is causing Linux to assign the wrong
ACPI fwnode / companion to the pci_device for the i915 iGPU.
Specifically under the PCI root bridge there are these 2 ACPI Device()s :
Scope (_SB.PCI0)
{
Device (GFX0)
{
Name (_ADR, 0x00020000) // _ADR: Address
}
...
Device (VID)
{
Name (_ADR, 0x00020000) // _ADR: Address
...
Method (_DOS, 1, NotSerialized) // _DOS: Disable Output Switching
{
VDP8 = Arg0
VDP1 (One, VDP8)
}
Method (_DOD, 0, NotSerialized) // _DOD: Display Output Devices
{
...
}
...
}
}
The non-functional GFX0 ACPI device is a problem, because this gets
returned as ACPI companion-device by acpi_find_child_device() for the iGPU.
This is a long standing problem and the i915 driver does use the ACPI
companion for some things, but works fine without it.
However since commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()")
acpi_get_pci_dev() relies on the physical-node pointer in the acpi_device
and that is set on the wrong acpi_device because of the wrong
acpi_find_child_device() return. This breaks the ACPI video code,
leading to non working backlight control in some cases.
Add a type.backlight flag, mark ACPI video bus devices with this and make
find_child_checks() return a higher score for children with this flag set,
so that it picks the right companion-device.

If the GPU drivers have loaded, they may be able to report whether
any LCD panels were found. Allow using this information to factor
in whether to enable the fallback logic for making an acpi_video0
