Hi Dave & Sima, Mostly fixes in this drm-intel-gt-next PR at this time. One thing to pay attention is the limitation of number of relocations to INT_MAX which might impact synthetic tests, but no real workloads. Regards, Joonas *** drm-intel-gt-next-2024-08-23: UAPI Changes: - drm/i915: 2 GiB of relocations ought to be enough for anybody* Limit the number of relocations to INT_MAX. Only impact should be onsynthetic tests. Driver Changes: - Fix for #11396: GPU Hang and rcs0 reset on Cherrytrail platform - Fix Virtual Memory mapping boundaries calculation (Andi) - Fix for #11255: Long hangs in buddy allocator with DG2/A380 without Resizable BAR since 6.9 (David) - Mark the GT as dead when mmio is unreliable (Chris, Andi) - Workaround additions / fixes for MTL, ARL and DG2 (John H, Nitin) - Enable partial memory mapping of GPU virtual memory (Andi, Chris) - Prevent NULL deref on intel_memory_regions_hw_probe (Jonathan, Dan) - Avoid UAF on intel_engines_release (Krzysztof) - Don't update PWR_CLK_STATE starting Gen12 (Umesh) - Code and dmesg cleanups (Andi, Jesus, Luca) The following changes since commit 3b85152cb167bd24fe84ceb91b719b5904ca354f: drm/i915/gem: Suppress oom warning in favour of ENOMEM to userspace (2024-06-28 00:11:01 +0200) are available in the Git repository at: https://gitlab.freedesktop.org/drm/i915/kernel.git tags/drm-intel-gt-next-2024-08-23 for you to fetch changes up to 255fc1703e42321b5afdedc8259ad03c7cc533ec: drm/i915/gem: Calculate object page offset for partial memory mapping (2024-08-21 15:28:33 +0200) ---------------------------------------------------------------- UAPI Changes: - Limit the number of relocations to INT_MAX (Tvrtko) Only impact should be synthetic tests.
