Use the helper screen_info_video_type() to get the framebuffer
type from struct screen_info. Handle supported values in sorted
switch statement.
Reading orig_video_isVGA is unreliable. On most systems it is a
VIDEO_TYPE_ constant. On some systems with VGA it is simply set
to 1 to signal the presence of a VGA output. See vga_probe() for
an example. Retrieving the screen_info type with the helper
screen_info_video_type() detects these cases and returns the
appropriate VIDEO_TYPE_ constant. For VGA, sysfb creates a device
named "vga-framebuffer".
The sysfb code has been taken from vga16fb, where it likely didn't
work correctly either. With this bugfix applied, vga16fb loads for
compatible vga-framebuffer devices.

git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"Not a lot going on in the EFI tree this cycle. The only thing that
stands out is the new support for SBAT metadata, which was a bit
contentious when it was first proposed, because in the initial
incarnation, it would have required us to maintain a revocation index,
and bump it each time a vulnerability affecting UEFI secure boot got
fixed. This was shot down for obvious reasons.
This time, only the changes needed to emit the SBAT section into the
PE/COFF image are being carried upstream, and it is up to the distros
to decide what to put in there when creating and signing the build.
This only has the EFI zboot bits (which the distros will be using for
arm64); the x86 bzImage changes should be arriving next cycle,
presumably via the -tip tree.
Summary:
- Add support for emitting a .sbat section into the EFI zboot image,
so that downstreams can easily include revocation metadata in the
signed EFI images
- Align PE symbolic constant names with other projects
- Bug fix for the efi_test module
- Log the physical address and size of the EFI memory map when
failing to map it
- A kerneldoc fix for the EFI stub code"
* tag 'efi-next-for-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
include: pe.h: Fix PE definitions
efi/efi_test: Fix missing pending status update in getwakeuptime

efi/libstub: Describe missing 'out' parameter in efi_load_initrd

Add support for the stackleak feature. It initializes the stack with the
poison value before returning from system calls which improves the kernel
security.
At the same time, disables the plugin in EFI stub code because EFI stub
is out of scope for the protection.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"The headline feature is the re-enablement of support for Arm's
Scalable Matrix Extension (SME) thanks to a bumper crop of fixes
from Mark Rutland.
If matrices aren't your thing, then Ryan's page-table optimisation
work is much more interesting.
Summary:
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls
- Fix a node refcount imbalance in the PSCI device-tree code
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code
Entry code:
- Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
selected
Memory management:
- Prevent BSS exports from being used by the early PI code
- Propagate level and stride information to the low-level TLB
invalidation routines when operating on hugetlb entries
- Use the page-table contiguous hint for vmap() mappings with
VM_ALLOW_HUGE_VMAP where possible
- Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
and hook this up on arm64 so that the trailing DSB (used to publish
the updates to the hardware walker) can be deferred until the end
of the mapping operation
- Extend mmap() randomisation for 52-bit virtual addresses (on par
with 48-bit addressing) and remove limited support for
randomisation of the linear map
Perf and PMUs:
- Add support for probing the CMN-S3 driver using ACPI
- Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers
Selftests:
- Fix FPSIMD and SME tests to align with the freshly re-enabled SME
support
- Fix default setting of the OUTPUT variable so that tests are
installed in the right location
vDSO:
- Replace raw counter access from inline assembly code with a call to
the the __arch_counter_get_cntvct() helper function
Miscellaneous:
- Add some missing header inclusions to the CCA headers
- Rework rendering of /proc/cpuinfo to follow the x86-approach and
avoid repeated buffer expansion (the user-visible format remains
identical)
- Remove redundant selection of CONFIG_CRC32
- Extend early error message when failing to map the device-tree
blob"

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.

precursor to getting the real driver in later, but to unblock

ASoC:
- Support for automatically enumerating DAIs from standards
conforming SoundWire SDCA devices; not much used as of this
writing, rather for future implementations
- Conversion of quite a few drivers to newer GPIO APIs
- Continued cleanups and helper usages in allover places
- Support for a wider range of Intel AVS platforms
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32
Everest Semiconductor ES8375 and ES8389, Longsoon-1 AC'97
controllers, nVidia Tegra264, Richtek ALC203 and RT9123 and
Rockchip SAI controllers
HD-audio:
- Lots of cleanups of TAS2781 codec drivers
- A new HD-audio control bound via ACPI for Nvidia
- Support for Tegra264, Intel WCL, usual new codec quirks
USB-audio:
- Fix a race at removal of MIDI device
- Pioneer DJM-V10 support, Scarlett2 driver cleanups

Pull core x86 updates from Ingo Molnar:
"Boot code changes:
- A large series of changes to reorganize the x86 boot code into a
better isolated and easier to maintain base of PIC early startup
code in arch/x86/boot/startup/, by Ard Biesheuvel.
Motivation & background:
| Since commit
|
| c88d71508e36 ("x86/boot/64: Rewrite startup_64() in C")
|
| dated Jun 6 2017, we have been using C code on the boot path in a way
| that is not supported by the toolchain, i.e., to execute non-PIC C
| code from a mapping of memory that is different from the one provided
| to the linker. It should have been obvious at the time that this was a
| bad idea, given the need to sprinkle fixup_pointer() calls left and
| right to manipulate global variables (including non-pointer variables)
| without crashing.
|
| This C startup code has been expanding, and in particular, the SEV-SNP
| startup code has been expanding over the past couple of years, and
| grown many of these warts, where the C code needs to use special
| annotations or helpers to access global objects.
This tree includes the first phase of this work-in-progress x86

KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets().
The code uses mock_coeff_template.length_bytes (4 bytes) for register value
allocations. But later, this length is set to 8 bytes which causes
test code failures.
As fix, just remove the lenght override, keeping the original value 4
for all operations.

The KVM/arm64 uses SMCCC to detect hypervisor presence. That code is
private, and it follows the SMCCC specification. Other existing and
emerging hypervisor guest implementations can and should use that
standard approach as well.
Factor out a common infrastructure that the guests can use, update KVM
to employ the new API. The central notion of the SMCCC method is the
UUID of the hypervisor, and the new API follows that.
No functional changes. Validated with a KVM/arm64 guest.

SBAT is a mechanism which improves SecureBoot revocations of UEFI binaries
by introducing a generation-based technique. Compromised or vulnerable UEFI
binaries can be prevented from booting by bumping the minimal required
generation for the specific component in the bootloader. More information
on the SBAT can be obtained here:
https://github.com/rhboot/shim/blob/main/SBAT.md
Upstream Linux kernel does not currently participate in any way in SBAT as
there's no existing policy in how SBAT generation number should be
defined. Keep the status quo and provide a mechanism for distro vendors and
anyone else who signs their kernel for SecureBoot to include their own SBAT
data. This leaves the decision on the policy to the vendor. Basically, each
distro implementing SecureBoot today, will have an option to inject their
own SBAT data during kernel build and before it gets signed by their
SecureBoot CA. Different distro do not need to agree on the common SBAT
component names or generation numbers as each distro ships its own 'shim'
with their own 'vendor_cert'/'vendor_db'
Implement support for embedding SBAT data for architectures using
zboot (arm64, loongarch, riscv). Put '.sbat' section in between '.data' and
'.text' as the former also covers '.bss' and thus must be the last one.

increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

SDEI usually initialize with the ACPI table, but on platforms where
ACPI is not used, the SDEI feature can still be used to handle
specific firmware calls or other customized purposes. Therefore, it
is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES.
In commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES
in acpi_init()"), to make APEI ready earlier, sdei_init was moved
into acpi_ghes_init instead of being a standalone initcall, adding
ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the
flexibility and usability of SDEI.
This patch corrects the dependency in Kconfig and splits sdei_init()
into two separate functions: sdei_init() and acpi_sdei_init().
sdei_init() will be called by arch_initcall and will only initialize
the platform driver, while acpi_sdei_init() will initialize the
device from acpi_ghes_init() when ACPI is ready. This allows the
initialization of SDEI without ACPI_APEI_GHES enabled.

Fix CPU resume latency constraint units sent to device manager through the
TI SCI API. The device manager expects CPU resume latency to be in msecs
which is passed in with the TI SCI API [1]. CPU latency constraints are
set in userspace using the PM QoS framework which uses usecs as the unit.
Since PM QoS uses usecs for units and the device manager expects msecs as
the unit, TI SCI needs to convert from usecs to msecs before passing to
device manager.

The Qualcomm SCP firmware in X1E machines like the Lenovo ThinkPad T14s
does not set the FastChannel supported attribute bit for PERF_LEVEL_GET
but crashes when falling back to regular messaging.
Use the new SCMI quirk framework to force FastChannel initialisation for
this implementation.
Note that we can add an upper bound on the version matching when we
learn which version has a fix (or limit matching using a SoC compatible
string in the unlikely event that always enabling FC causes trouble
somewhere).

Currently the perf and powercap protocol relies on the protocol domain
attributes, which just ensures that one fastchannel per domain, before
instantiating fastchannels for all possible message-ids. Fix this by
ensuring that each message-id supports fastchannel before initialization.
