Introduce a GpuHal trait and per-family dispatch so GPU boot
behavior can vary by architecture. Move wait_gfw_boot_completion()
from the standalone gfw module into gpu/hal/tu102.rs as the first
GpuHal implementation. All architectures currently dispatch to this
implementation, preserving existing behavior.

GA100 is a compute-only variant of GA102 that boots GSP-RM like a
Turing, although it also has its own unique requirements.
Now that all the pieces are in place, we can enable GA100 support.
Although architecturally like an Ampere, GA100 uses the same GSP-RM
firmware files as Turing, and therefore must boot it like Turing does.
However, as a compute-only part, GA100 has no display engine.

The GPU's ROM may begin with an Init-from-ROM (IFR) header that precedes
the PCI Expansion ROM images (VBIOS). When present, the PROM shadow
method must parse this header to determine the offset where the PCI ROM
images actually begin, and adjust all subsequent reads accordingly.
On most GPUs this is not needed because the IFR microcode has already
applied the ROM offset so that PROM reads transparently skip the header.
On GA100, for whatever reason, the IFR offset is not applied to PROM
reads. Therefore, the search for the PCI expansion must skip the IFR
header, if found.

Introduce FbHal method frts_size() to return the size of the FRTS
window. GA100 is a special case in that although there is an
FRTS, its size must arbitrarily be set to 0.
Note that we cannot use supports_display() to determine the FRTS
size because there are other GPUs (e.g. GA102GL) that have display
disabled (and so supports_display() returns False), but the FRTS
window size still needs to be 1MB.

Init-from-ROM (IFR) is a special GPU feature used for power management
on some Nvidia GPUs. It references data in the VBIOS for its operation,
but for drivers the important piece is the header that precedes the
VBIOS PCI Expansion ROM. Parsing VBIOS is necessary to boot GSP-RM on
Turing, Ampere, and Ada GPUs.
Most such GPUs do not need to parse the IFR header in order to find the
VBIOS, but the Nvidia GA100 is the exception. GA100 lacks a display
engine, so the PRAMIN method (which reads the VBIOS from VRAM via
display hardware) is unavailable, forcing the driver to read the ROM
directly via PROM. On other similar GPUs, either PRAMIN succeeds before
PROM is tried, or the IFR hardware has already applied the ROM offset
so that PROM reads transparently skip the IFR header.
Note that GH100 also does not have a display engine, but it uses a
completely different method to boot GSP-RM.
This information is derived from NVIDIA's open-source GPU kernel module
driver (aka OpenRM), specifically the NV_PBUS_IFR_FMT_FIXEDx definitions
in dev_bus.h and the parsing logic in s_romImgFindPciHeader_TU102().

Define the MMU_CONTROL register block with the kernel's register! macro
and replace the existing hand-written MMU register definitions with typed

This adds typed definitions for the MMU IRQ registers and the per-address
space MMU_AS_CONTROL registers, including TRANSTAB, MEMATTR, LOCKADDR,
COMMAND, FAULTSTATUS, STATUS, and TRANSCFG. It also introduces typed
enums for MMU commands, fault types, access types, address space modes,
memory attributes, and related MMU configuration fields.
For logical 64-bit MMU registers that are exposed as split 32-bit MMIO
registers, define both the typed 64-bit view and explicit low/high 32-bit
registers so the register layout remains documented without relying on
native 64-bit MMIO accesses.
This reduces open-coded bit manipulation, keeps MMU register layout
knowledge in one place, and makes the definitions easier to read and

Initial SoC Slider support
SoC Slider is an SoC-wide power/performance policy setting.
On SoC Slider systems, EPP plays a diminished role.
Whitespace cleanup via: indent -npro -kr -i8 -ts8 -sob -l160 -ss -ncs -cp1
No functional changes
Signed-off-by: Len Brown <len.brown@intel.com>
x86_energy_perf_policy accesses the SoC Slider via standard
user/kernel APIs to the processor_thermal_soc_slider driver.
Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.
Signed-off-by: Len Brown <len.brown@intel.com>
When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.
n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced". Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of
the saved ring buffer. This is because the ring buffer being read by
user space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other accounting
as well. On boot up, the "reader page" is accounted for but a rewind may
put it back into the buffer and then the reader page may be accounted
for again.
Save off the original reader page and skip accounting it when scanning
the pages in the ring buffer.

Pull io_uring fixes from Jens Axboe:
- Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
here we are
- A few fixes covering minor issues introduced in this merge window
- data race annotation to shut up KCSAN for when io-wq limits are
applied
- A nospec addition for direct descriptor file updating. Rest of the
direct descriptor path already had this, but for some reason the
update did not. Now they are all the same
- Various minor defensive changes that claude identified and suggested
terrible fixes for, turned into actually useful cleanups:
- Use kvfree() for the imu cache. These can come from kmalloc or
vmalloc depending on size, but the in-cache ones are capped
where it's always kmalloc based. Change to kvfree() in the
cleanup path, making future changes unlikely to mess that up
- Negative kbuf consumption lengths. Can't happen right now, but
cqe->res is used directly, which if other codes changes could
then be an error value
- Fix for an issue with the futex code, where partial wakes on a
vectored fuxes would potentially wake the same futex twice, rather
than move on to the next one. This could confuse an application as it
would've expected the next futex to have been woken
- Fix for a bug with ring resizing, where SQEs or CQEs might not have
been copied correctly if large SQEs or CQEs are used in the ring.
Application side issue, where SQEs or CQEs might have been lost
during resize
- Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
multishot poll to not be terminated when it's nested, like it should
have been

Merge tag 'ntfs-for-7.1-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs
Pull ntfs updates from Namjae Jeon:
- Fix potential data leakage by zeroing the portion of the straddle
block beyond initialized_size when reading non-resident attributes
- Remove unnecessary zeroing in ntfs_punch_hole() for ranges beyond
initialized_size, as they are already returned as zeros on read
- Fix writable check in ntfs_file_mmap_prepare() to correctly handle
shared mappings using VMA_SHARED_BIT | VMA_MAYWRITE_BIT
- Use page allocation instead of kmemdup() for IOMAP_INLINE data to
ensure page-aligned address and avoid BUG trap in
iomap_inline_data_valid() caused by the page boundary check
- Add a size check before memory allocation in ntfs_attr_readall() and
reject overly large attributes
- Remove unneeded noop_direct_IO from ntfs_aops as it is no longer
required following the FMODE_CAN_ODIRECT flag
- Fix seven static analysis warnings reported by Smatch

Here is a single SPDX-like change for 7.1-rc1. It explicitly allows the
use of SPDX-FileCopyrightText which has been used already in many files.
At the same time, update checkpatch to catch any "non allowed" spdx
identifiers as we don't want to go overboard here.
This has been in linux-next for a long time with no reported problems.

Here is the char/misc/iio and other smaller driver subsystem updates for
7.1-rc1. Lots of stuff in here, all tiny, but relevant for the
different drivers they touch. Major points in here is:
- the usual large set of new IIO drivers and updates for that
subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported

This is quite a big set of fixes, almost all from Johan Hovold who is on
an ongoing quest to clean up issues with probe and removal handling in
drivers. There isn't anything too concerning here especially with the
deregistration stuff which will very rarely get run in production
systems since this is all platform devices in the SoC on embedded
hardware, but it's all real issues which should be fixed. There's more
in flight here.
We also have a few other minor fixes, one from Felix Gu along the same
lines as Johan's work and a couple of documentation things.
