2024-12-19drm/sched: Fix drm_sched_fini() docu generationBagas Sanjaya
Commit baf4afc5831438 ("drm/sched: Improve teardown documentation") added a list of drm_sched_fini()'s problems. The list triggers htmldocs warning (but renders correctly in htmldocs output): Documentation/gpu/drm-mm:571: ./drivers/gpu/drm/scheduler/sched_main.c:1359: ERROR: Unexpected indentation. Separate the list from the preceding paragraph by a blank line to fix the warning. While at it, also end the aforementioned paragraph by a colon.

2024-12-18drm/amdgpu: don't access invalid schedPierre-Eric Pelloux-Prayer
Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()") accessing job->base.sched can produce unexpected results as the initialisation of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the memset. This commit fixes an issue when a CS would fail validation and would be rejected after job->num_ibs is incremented. In this case, amdgpu_ib_free(ring->adev, ...) will be called, which would crash the machine because the ring value is bogus. To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this because the device is actually not used in this function. The next commit will remove the ring argument completely.

2024-12-17drm: rework FB_CORE dependencyArnd Bergmann
The 'select FB_CORE' statement moved from CONFIG_DRM to DRM_CLIENT_LIB, but there are now configurations that have code calling into fb_core as built-in even though the client_lib itself is a loadable module: x86_64-linux-ld: drivers/gpu/drm/drm_fb_helper.o: in function `drm_fb_helper_set_suspend': drm_fb_helper.c:(.text+0x2c6): undefined reference to `fb_set_suspend' x86_64-linux-ld: drivers/gpu/drm/drm_fb_helper.o: in function `drm_fb_helper_resume_worker': drm_fb_helper.c:(.text+0x2e1): undefined reference to `fb_set_suspend' In addition to DRM_CLIENT_LIB, the 'select' needs to be at least in DRM_KMS_HELPER and DRM_GEM_SHMEM_HELPER, so add it here.

2024-12-17i915/guc: Ensure busyness counter increases motonicallyUmesh Nerlige Ramappa
Active busyness of an engine is calculated using gt timestamp and the context switch in time. While capturing the gt timestamp, it's possible that the context switches out. This race could result in an active busyness value that is greater than the actual context runtime value by a small amount. This leads to a negative delta and throws off busyness calculations for the user. If a subsequent count is smaller than the previous one, just return the previous one, since we expect the busyness to catch up.

On GT reset, we store total busyness counts for all engines and re-register the utilization buffer with GuC.

2024-12-14bpf: Avoid deadlock caused by nested kprobe and fentry bpf programsPriya Bala Govindasamy
BPF program types like kprobe and fentry can cause deadlocks in certain situations. If a function takes a lock and one of these bpf programs is hooked to some point in the function's critical section, and if the bpf program tries to call the same function and take the same lock it will lead to deadlock. These situations have been reported in the following bug reports.

The bugs reported by syzbot are due to tracepoint bpf programs being called in the critical sections. This patch does not aim to fix deadlocks caused by tracepoint programs. However, it does prevent deadlocks from occurring in similar situations due to kprobe and fentry programs.

2024-12-13Merge branch 'explicit-raw_tp-null-arguments'Alexei Starovoitov
Kumar Kartikeya Dwivedi says: ==================== Explicit raw_tp NULL arguments This set reverts the raw_tp masking changes introduced in commit cb4158ce8ec8 ("bpf: Mark raw_tp arguments with PTR_MAYBE_NULL") and replaces it wwith an explicit list of tracepoints and their arguments which need to be annotated as PTR_MAYBE_NULL. More context on the fallout caused by the masking fix and subsequent discussions can be found in [0]. To remedy this, we implement a solution of explicitly defined tracepoint and define which args need to be marked NULL or scalar (for IS_ERR case). The commit logs describes the details of this approach in detail. We will follow up this solution an approach Eduard is working on to perform automated analysis of NULL-ness of tracepoint arguments. The current PoC is available here: - LLVM branch with the analysis: https://github.com/eddyz87/llvm-project/tree/nullness-for-tracepoint-params - Python script for merging of analysis results: https://gist.github.com/eddyz87/e47c164466a60e8d49e6911cff146f47 The idea is to infer a tri-state verdict for each tracepoint parameter: definitely not null, can be null, unknown (in which case no assumptions should be made). Using this information, the verifier in most cases will be able to precisely determine the state of the tracepoint parameter without any human effort. At that point, the table maintained manually in this set can be dropped and replace with this automated analysis tool's result. This will be kept up to date with each kernel release.
