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) - Create per-gt debugfs files (Andi) - Documentation and kerneldoc fixes (Nirmoy, Lee) - Selftest improvements (Fei, Jonathan) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> From: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ZC6APj/feB+jBf2d@jlahtine-mobl.ger.corp.intel.com
