drm/amdgpu: Make pin_size values atomic

2018-09-15T07:47:01+00:00

commit a5ccfe5c20740f2fbf00291490cdf8d2373ec255 upstream. Concurrent execution of the non-atomic arithmetic could result in completely bogus values. v2: * Rebased on v2 of the previous patch Cc: stable@vger.kernel.org Bugzilla: https://bugs.freedesktop.org/106872 Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: Keep track of amount of pinned CPU visible VRAM

2018-09-15T07:47:01+00:00

commit ddc21af4d0f37f42b33c54cb69b215997fe5b082 upstream. Instead of CPU invisible VRAM. Preparation for the following, no functional change intended. v2: * Also change amdgpu_vram_mgr_bo_invisible_size to amdgpu_vram_mgr_bo_visible_size, allowing further simplification (Christian König) Cc: stable@vger.kernel.org Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu/vg20:Restruct uvd.inst to support multiple instances

2018-05-18T21:08:12+00:00

Vega20 has dual-UVD. Need add multiple instances support for uvd. Restruct uvd.inst, using uvd.inst[0] to replace uvd.inst->. Repurpose amdgpu_ring::me for instance index, and initialize to 0. There are no any logical changes here. Signed-off-by: James Zhu Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: defer test IBs on the rings at boot (V3)

2018-05-15T18:43:21+00:00

amdgpu_ib_ring_tests() runs test IB's on rings at boot contributes to ~500 ms of amdgpu driver's boot time. This patch defers it and ensures that its executed in amdgpu_info_ioctl() if it wasn't scheduled. V2: Use queue_delayed_work() & flush_delayed_work(). V3: removed usage of separate wq, ensure ib tests is run before enabling clockgating. Signed-off-by: Shirish S Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amd/pp: Remove struct pp_gpu_power

2018-05-15T18:43:18+00:00

Currently smu only calculate average gpu power in real time. for vddc/vddci/max power, User need to set start time and end time, firmware can calculate the average vddc/vddci/max power. but the type of return values is not unified. For Vi, return type is uint. For vega, return type is float. so this struct can't be suitable for all asics. Acked-by: Alex Deucher Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher

drm/gpu-sched: fix force APP kill hang(v4)

2018-05-15T18:43:17+00:00

issue: there are VMC page fault occurred if force APP kill during 3dmark test, the cause is in entity_fini we manually signal all those jobs in entity's queue which confuse the sync/dep mechanism: 1)page fault occurred in sdma's clear job which operate on shadow buffer, and shadow buffer's Gart table is cleaned by ttm_bo_release since the fence in its reservation was fake signaled by entity_fini() under the case of SIGKILL received. 2)page fault occurred in gfx' job because during the lifetime of gfx job we manually fake signal all jobs from its entity in entity_fini(), thus the unmapping/clear PTE job depend on those result fence is satisfied and sdma start clearing the PTE and lead to GFX page fault. fix: 1)should at least wait all jobs already scheduled complete in entity_fini() if SIGKILL is the case. 2)if a fence signaled and try to clear some entity's dependency, should set this entity guilty to prevent its job really run since the dependency is fake signaled. v2: splitting drm_sched_entity_fini() into two functions: 1)The first one is does the waiting, removes the entity from the runqueue and returns an error when the process was killed. 2)The second one then goes over the entity, install it as completion signal for the remaining jobs and signals all jobs with an error code. v3: 1)Replace the fini1 and fini2 with better name 2)Call the first part before the VM teardown in amdgpu_driver_postclose_kms() and the second part after the VM teardown 3)Keep the original function drm_sched_entity_fini to refine the code. v4: 1)Rename entity->finished to entity->last_scheduled; 2)Rename drm_sched_entity_fini_job_cb() to drm_sched_entity_kill_jobs_cb(); 3)Pass NULL to drm_sched_entity_fini_job_cb() if -ENOENT; 4)Replace the type of entity->fini_status with "int"; 5)Remove the check about entity->finished.
