gpu/drm: Eliminate DRM_SCHED_PRIORITY_UNSET

2023-11-08T13:11:00+00:00

[ Upstream commit fa8391ad68c16716e2c06ada397e99ceed2fb647 ] Eliminate DRM_SCHED_PRIORITY_UNSET, value of -2, whose only user was amdgpu. Furthermore, eliminate an index bug, in that when amdgpu boots, it calls drm_sched_entity_init() with DRM_SCHED_PRIORITY_UNSET, which uses it to index sched->sched_rq[].

drm/amdgpu: Unset context priority is now invalid

2023-11-08T13:11:00+00:00

[ Upstream commit eab0261967aeab528db4d0a51806df8209aec179 ] A context priority value of AMD_CTX_PRIORITY_UNSET is now invalid--instead of carrying it around and passing it to the Direct Rendering Manager--and it becomes AMD_CTX_PRIORITY_NORMAL in amdgpu_ctx_ioctl(), the gateway to context creation.

drm/amdgpu: fix pstate setting issue

2022-10-21T20:12:09+00:00

[WHY] 0, original pstate X 1, ctx_A_create -> ctx_A->stable_pstate = X 2, ctx_A_set_pstate (Y) -> current pstate is Y (PEAK or STANDARD) 3, ctx_B_create -> ctx_B->stable_pstate = Y 4, ctx_A_destroy -> restore pstate to X 5, ctx_B_destroy -> restore pstate to Y Above sequence will cause final pstate is wrong (Y), should be original X. [HOW] When ctx_B create, if ctx_A touched pstate setting (not auto, stable_pstate_ctx != NULL), set ctx_B->stable_pstate the same value as ctx_A saved, if stable_pstate_ctx == NULL, fetch current pstate to fill ctx_B->stable_pstate.

drm/amdgpu: revert "partial revert "remove ctx->lock" v2"

2022-09-13T18:33:01+00:00

This reverts commit 94f4c4965e5513ba624488f4b601d6b385635aec. We found that the bo_list is missing a protection for its list entries. Since that is fixed now this workaround can be removed again. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: use idr_init_base() to initialize mgr->ctx_handles

2022-07-28T14:35:55+00:00

idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based IDRs more efficient"), let us set an arbitrary base other than idr_init(), which uses base 0. Since, for this IDR, no ID < 1 is ever requested, using idr_init_base(&idr, 1) avoids unnecessary tree walks.

drm/amd/amdgpu: Enable high priority gfx queue

2022-06-06T18:41:25+00:00

Starting from SIENNA CICHLID asic supports two gfx pipes, enabling two graphics queues, 1 on each pipe, pipe0 queue0 would be the normal piority queue and pipe1 queue0 would be the high priority queue Only one queue per pipe is visble to SPI, SPI looks at the priority value assigned to CP_GFX_HQD_QUEUE_PRIORITY from each of the queue's HQD/MQD. Create contexts applying AMDGPU_CTX_PRIORITY_HIGH which submits job to the high priority queue on GFX pipe1. There would be starvation of LP workload if HP workload is always available. v2: - remove unnecessary check(Nirmoy) - make pipe1 hardware support a separate patch(Nirmoy) - remove duplicate code(Shashank) - add CSA support for second gfx pipe(Alex) v3(Christian): - fix incorrect indentation - merge COMPUTE and GFX switch cases as both calls the same function. v4: - rebase w/ latest code base Signed-off-by: Arunpravin Paneer Selvam Acked-by: Christian König Signed-off-by: Alex Deucher
