Hi Dave & Daniel,
Here goes the final drm-intel-gt-next pull request for v6.4.
As top items we have a fix for context runtime accounting, Meteorlake
enabling, DMAR error noise elimination due to GPU error capture, BAR
resizing forcewake fix and memory contents clearing fix for discrete.
More robust GuC loading on systems with IFWI that leaves GPU to slow
frequency and a potential UAF closed on perf add_config IOCTL.
There is also change to the uAPI headers to eliminate flexible-array
member kernel-wide request, which does not impact binaries and also
should not impact compilation.
Then the usual amount of smaller fixes and cleanups. A good amount of
kerneldoc fixes included.
Best Regards, Joonas

UAPI Changes:
- (Build-time only, should not have any impact)
drm/i915/uapi: Replace fake flex-array with flexible-array member
"Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members instead."
This is on core kernel request moving towards GCC 13.
Driver Changes:
- Fix context runtime accounting on sysfs fdinfo for heavy workloads (Tvrtko)
- Add support for OA media units on MTL (Umesh)
- Add new workarounds for Meteorlake (Daniele, Radhakrishna, Haridhar)
- Fix sysfs to read actual frequency for MTL and Gen6 and earlier
(Ashutosh)
- Synchronize i915/BIOS on C6 enabling on MTL (Vinay)
- Fix DMAR error noise due to GPU error capture (Andrej)
- Fix forcewake during BAR resize on discrete (Andrzej)
- Flush lmem contents after construction on discrete (Chris)
- Fix GuC loading timeout on systems where IFWI programs low boot
frequency (John)
- Fix race condition UAF in i915_perf_add_config_ioctl (Min)
- Sanitycheck MMIO access early in driver load and during forcewake
(Matt)
- Wakeref fixes for GuC RC error scenario and active VM tracking (Chris)
- Cancel HuC delayed load timer on reset (Daniele)
- Limit double GT reset to pre-MTL (Daniele)
- Use i915 instead of dev_priv insied the file_priv structure (Andi)
- Improve GuC load error reporting (John)
- Simplify VCS/BSD engine selection logic (Tvrtko)
- Perform uc late init after probe error injection (Andrzej)
- Fix format for perf_limit_reasons in debugfs (Vinay)
