User queues are isolated in the MES scheduler, but we still need to serialize between kernel queues and user queues. For enforce isolation, group KGD user queues with KFD user queues. v2: split out variable renaming, add config guards v3: use new function names Reviewed-by: Sunil Khatri Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c index c58d32983c45e..e1dca45a152b6 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c @@ -1970,6 +1970,9 @@ static void amdgpu_gfx_kfd_sch_ctrl(struct amdgpu_device *adev, u32 idx, if (adev->gfx.userq_sch_req_count[idx] == 0) { cancel_delayed_work_sync(&adev->gfx.enforce_isolation[idx].work); if (!adev->gfx.userq_sch_inactive[idx]) { +#ifdef CONFIG_DRM_AMDGPU_NAVI3X_USERQ + amdgpu_userq_stop_sched_for_enforce_isolation(adev, idx); +#endif if (adev->kfd.init_complete) amdgpu_amdkfd_stop_sched(adev, idx); adev->gfx.userq_sch_inactive[idx] = true; @@ -2027,6 +2030,9 @@ void amdgpu_gfx_enforce_isolation_handler(struct work_struct *work) /* Tell KFD to resume the runqueue */ WARN_ON_ONCE(!adev->gfx.userq_sch_inactive[idx]); WARN_ON_ONCE(adev->gfx.userq_sch_req_count[idx]); +#ifdef CONFIG_DRM_AMDGPU_NAVI3X_USERQ + amdgpu_userq_start_sched_for_enforce_isolation(adev, idx); +#endif if (adev->kfd.init_complete) amdgpu_amdkfd_start_sched(adev, idx); adev->gfx.userq_sch_inactive[idx] = false;
