* drm/scheduler: Fix lockup in drm_sched_entity_kill()drm-qemu-next-fixesdrm-misc-next-fixesDmitry Osipenko2023-01-022-3/+3
| | | | | | | | | | | | | | | | | | | | | | The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

* drm/tests: reduce drm_mm_test stack usageArnd Bergmann2022-12-232-3/+5
| | | | | | | | | | | | | | | | | | The check_reserve_boundaries function uses a lot of kernel stack, and it gets inlined by clang, which makes __drm_test_mm_reserve use even more of it, to the point of hitting the warning limit: drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than] When building with gcc, this does not happen, but the structleak plugin can similarly increase the stack usage and needs to be disabled, as we do for all other kunit users.

Similarly when doing HDMI+HDMI cloning on g4x (only platform where we allow it) only one of the ports can receive infoframes and so again using any fancy stuff is a bad idea. We also don't track the inforames/audio state per-port so we'd end up with some kind of random mismash state when multipled encoders try to compute the same stuff. And the hardware will in fact automagically disable audio/infoframe transmission if you try to enable it for multiple HDMI ports at the same time. Thus disable all HDMI specific features when cloning.

The previous implementation added the value '4' (crc32's u32 size) to calculate the crc32_start offset which came across as a bit cryptic until you take a deeper look at the struct. This patch changes crc32_start offset to the 'version' member which is the first member of the struct gvt_firmware_header after crc32. It's worth mentioning that doing a build before/after this patch results in no binary output differences.
