commit ebca08fef88febdb0a898cefa7c99b9e25b3a984 upstream.
The _DDC method should return a buffer, or an integer in case of an error.
But some Lenovo laptops incorrectly return EDID as buffer in ACPI package.
Calling _DDC generates this ACPI Warning:
ACPI Warning: \_SB.PCI0.GP17.VGA.LCD._DDC: Return type mismatch - \
found Package, expected Integer/Buffer (20240827/nspredef-254)
Use the first element of the package to get the EDID buffer.
The DSDT:
Name (AUOP, Package (0x01)
{
Buffer (0x80)
{
...
}
})
...
Method (_DDC, 1, NotSerialized) // _DDC: Display Data Current
{
If ((PAID == AUID))
{
Return (AUOP) /* \_SB_.PCI0.GP17.VGA_.LCD_.AUOP */
}
ElseIf ((PAID == IVID))

}
ElseIf ((PAID == BOID))

commit 2da31ea2a085cd189857f2db0f7b78d0162db87a upstream.
Like the ASUS Vivobook X1504VAP and Vivobook X1704VAP, the ASUS Vivobook 14
X1404VAP has its keyboard IRQ (1) described as ActiveLow in the DSDT, which
the kernel overrides to EdgeHigh breaking the keyboard.
$ sudo dmidecode

Add the X1404VAP to the irq1_level_low_skip_override[] quirk table to fix
this.

commit 2ff0e408db36c21ed3fa5e3c1e0e687c82cf132f upstream.
Syzkaller has reported a warning in to_nfit_bus_uuid(): "only secondary
bus families can be translated". This warning is emited if the argument
is equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first
verifies that a user-provided value call_pkg->nd_family of type u64 is
not equal to 0. Then the value is converted to int, and only after that
is compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid
argument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while
the lower 32 bits are zero.
Furthermore, it is best to return EINVAL immediately upon seeing the
invalid user input. The WARNING is insufficient to prevent further
undefined behavior based on other invalid user input.
All checks of the input value should be applied to the original variable
call_pkg->nd_family.

commit 2fa87c71d2adb4b82c105f9191e6120340feff00 upstream.
Depending on the secureboot signature on EFI\BOOT\BOOTX86.EFI the
Lenovo Yoga Tab 3 UEFI will switch its OSID ACPI variable between
1 (Windows) and 4 (Android(GMIN)).
In Windows mode a GPIO event handler gets installed for GPO1 pin 5,
causing Linux' x86-android-tables code which deals with the general
brokenness of this device's ACPI tables to fail to probe with:
[ 17.853705] x86_android_tablets: error -16 getting GPIO INT33FF:01 5
[ 17.859623] x86_android_tablets x86_android_tablets: probe with driver
which renders sound, the touchscreen, charging-management,
battery-monitoring and more non functional.
Add ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS to the existing quirks for this
device to fix this.

invalid
[ Upstream commit 9e9b893404d43894d69a18dd2fc8fcf1c36abb7e ]
Prior to commit 496121c02127 ("ACPI: processor: idle: Allow probing on
platforms with one ACPI C-state"), the acpi_idle driver wouldn't load on
systems without a valid C-State at least as deep as C2.
The behavior was desirable for guests on hypervisors such as VMWare
ESXi, which by default don't have the _CST ACPI method, and set the C2
and C3 latencies to 101 and 1001 microseconds respectively via the FADT,
to signify they're unsupported.
Since the above change though, these virtualized deployments end up
loading acpi_idle, and thus entering the default C1 C-State set by
acpi_processor_get_power_info_default(); this is undesirable for a
system that's communicating to the OS it doesn't want C-States (missing
_CST, and invalid C2/C3 in FADT).
Make acpi_processor_get_power_info_fadt() return -ENODEV in that case,
so that acpi_processor_get_cstate_info() exits early and doesn't set
pr->flags.power = 1.

commit f818227a2f3d1d4f26469347e428323d61cc83f0 upstream.
Perhaps unsurprisingly there are some platforms where the GTDT isn't
quite right and the Platforms Timer array overflows the length of the
overall table.
While the recently-added sanity checking isn't wrong, it makes it
impossible to boot the kernel on offending platforms. Try to hobble
along and limit the Platform Timer count to the bounds of the table.

[ Upstream commit 8f62ca9c338aae4f73e9ce0221c3d4668359ddd8 ]
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.
Both ship with Android 4.4 as factory OS and have the usual broken DSDT
issues for x86 Android tablets.
Add a quirk to skip ACPI I2C client enumeration for the 5V version to
complement the existing quirk for the 9V version.

While analysing code for software and OF node for the corner case when
caller asks to read zero items in the supposed to be an array of values
I found that ACPI behaves differently to what OF does, i.e.
1. It returns -EINVAL when caller asks to read zero items from integer
array, while OF returns 0, if no other errors happened.
2. It returns -EINVAL when caller asks to read zero items from string
array, while OF returns -ENODATA, if no other errors happened.
Amend ACPI implementation to follow what OF does.

[ Upstream commit 5c0e00a391dd0099fe95991bb2f962848d851916 ]
The GHES driver overrides the panic= setting by force-rebooting the
system after a fatal hw error has been reported. The intent being that
such an error would be reported earlier.
However, this is not optimal when a hard-to-debug issue requires long
time to reproduce and when that happens, the box will get rebooted after
30 seconds and thus destroy the whole hw context of when the error
happened.
So rip out the default GHES panic timeout and honor the global one.
In the panic disabled (panic=0) case, the error will still be logged to
dmesg for later inspection and if panic after a hw error is really
required, then that can be controlled the usual way - use panic= on the
cmdline or set it in the kernel .config's CONFIG_PANIC_TIMEOUT.

The root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect
acpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause
a thread switch. Since there is no longer concurrent execution during
loongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()
directly in enable_gpe_wakeup().
The solution is similar to commit 22db06337f590d01 ("ACPI: sleep: Avoid

Commit c6a837088bed ("drm/amd/display: Fetch the EDID from _DDC if
available for eDP") added function dm_helpers_probe_acpi_edid(), which
fetches the EDID from the BIOS by calling acpi_video_get_edid().
acpi_video_get_edid() returns a pointer to the EDID, but this pointer
does not originate from kmalloc() - it is actually the internal
"pointer" field from an acpi_buffer struct (which did come from
kmalloc()).
dm_helpers_probe_acpi_edid() then attempts to kfree() the EDID pointer,
resulting in memory corruption which leads to random, intermittent
crashes (e.g. 4% of boots will fail with some Oops).
Fix this by allocating a new array (which can be safely freed) for the
EDID data, and correctly freeing the acpi_buffer pointer.
The only other caller of acpi_video_get_edid() is nouveau_acpi_edid():
remove the extraneous kmemdup() here as the EDID data is now copied in
acpi_video_device_EDID().

acpi_dev_irq_override() gets called approx. 30 times during boot (15 legacy
IRQs * 2 override_table entries). Of these 30 calls at max 1 will match
the non DMI checks done by acpi_dev_irq_override(). The dmi_check_system()
check is by far the most expensive check done by acpi_dev_irq_override(),
make this call the last check done by acpi_dev_irq_override() so that it
will be called at max 1 time instead of 30 times.

The TongFang GM5HG0A is a TongFang barebone design which is sold under
various brand names.
The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.
At least on the SKIKK Vanaheim variant the DMI product- and board-name
strings have been replaced by the OEM with "Vanaheim" so checking that
board-name contains "GM5HG0A" as is usually done for TongFang barebones
quirks does not work.
The DMI OEM strings do contain "GM5HG0A". I have looked at the dmidecode
for a few other TongFang devices and the TongFang code-name string being
in the OEM strings seems to be something which is consistently true.
Add a quirk checking one of the DMI_OEM_STRING(s) is "GM5HG0A" in the hope
that this will work for other OEM versions of the "GM5HG0A" too.

Like the Vivobook X1704VAP the X1504VAP has its keyboard IRQ (1) described
as ActiveLow in the DSDT, which the kernel overrides to EdgeHigh which
breaks the keyboard.
Add the X1504VAP to the irq1_level_low_skip_override[] quirk table to fix
this.

Commit a6021aa24f6417416d933 ("ACPI: EC: make EC support compile-time
conditional") only enable ACPI_EC on X86 by default, but the embedded
controller is also widely used on LoongArch laptops so we also enable
ACPI_EC for LoongArch.
The laptop driver cannot work without EC, so also update the dependency
of LOONGSON_LAPTOP to let it depend on APCI_EC.

This bug was first introduced in c27f3d011b08, where the author of the
patch probably meant to do DeleteMutex instead of ReleaseMutex. The
mutex leak was noticed later on and fixed in e4dfe108371, but the bogus
MutexRelease line was never removed, so do it now.

In acpi_decode_space() addr->info.mem.caching is checked on main level
for any resource type but addr->info.mem is part of union and thus
valid only if the resource type is memory range.
Move the check inside the preceeding switch/case to only execute it
when the union is of correct type.

- A series of fixes for the arm64 ptrace() implementation,
potentially leading to the kernel consuming uninitialised stack
variables when PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and
ZONE_DMA is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a
call to page_to_phys() (from patch_map()) which checks pfn_valid()
before vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI
ops when the kernel assumes 8-bit ASIDs but running under a
hypervisor on a system that implements 16-bit ASIDs (found running
Linux under Parallels on Apple M4)

Fix an issue detected by syzbot with KASAN:
BUG: KASAN: vmalloc-out-of-bounds in cmd_to_func drivers/acpi/nfit/
core.c:416 [inline]
BUG: KASAN: vmalloc-out-of-bounds in acpi_nfit_ctl+0x20e8/0x24a0
drivers/acpi/nfit/core.c:459
The issue occurs in cmd_to_func when the call_pkg->nd_reserved2
array is accessed without verifying that call_pkg points to a buffer
that is appropriately sized as a struct nd_cmd_pkg. This can lead
to out-of-bounds access and undefined behavior if the buffer does not
have sufficient space.
To address this, a check was added in acpi_nfit_ctl() to ensure that
buf is not NULL and that buf_len is less than sizeof(*call_pkg)
before accessing it. This ensures safe access to the members of
call_pkg, including the nd_reserved2 array.

To avoid arch-specific code in general ACPI initialization flow,
introduce a weak symbol acpi_arch_init().
Currently, arm64 and riscv can utillize this to insert their
arch-specific flow.
In the future, other architectures can also have a chance to define
their own arch-specific ACPI initialization process if necessary.

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd updates from Jason Gunthorpe:
"Several new features and uAPI for iommufd:
- IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the
backing memory for an iommu mapping. To date VFIO/iommufd have used
VMA's and pin_user_pages(), this now allows using memfds and
memfd_pin_folios(). Notably this creates a pure folio path from the
memfd to the iommu page table where memory is never broken down to
PAGE_SIZE.
- IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between
two processes. Combined with the above this allows iommufd to
support a VMM re-start using exec() where something like qemu would
exec() a new version of itself and fd pass the memfds/iommufd/etc
to the new process. The memfd allows DMA access to the memory to
continue while the new process is getting setup, and the
CHANGE_PROCESS updates all the accounting.
- Support for fault reporting to userspace on non-PRI HW, such as ARM
stall-mode embedded devices.
- IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed
virtual iommu. This will be used by VMMs to access hardware
features that are contained with in a VM. The first use is to
inform the kernel of the virtual SID to physical SID mapping when
issuing SID based invalidation on ARM. Further uses will tie HW
features that are directly accessed by the VM, such as invalidation
queue assignment and others.
- IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual
device to physical device within a VIOMMU. Minimially this is used
to translate VM issued cache invalidation commands from virtual to
physical device IDs.
- Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work
with the VIOMMU
- ARM SMMuv3 support for nested translation. Using the VIOMMU and
VDEVICE the driver can model this HW's behavior for nested
translation. This includes a shared branch from Will"
