From 07625a961637a4cecf7e1419a7661057df78eb2c Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Fri, 19 Jan 2018 20:29:17 +0800 Subject: [PATCH 3616/4131] drm/amdgpu: don't use MM idle_work for SRIOV(v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SRIOV doesn't give VF cg/pg feature so the MM's idle_work is skipped for SR-IOV v2: remove superfluous changes since idle_work is not scheduled for SR-IOV so the condition check for SR-IOV inside idle_work also can be dropped v3: drop the SRIOV check in amdgpu_vce/uvd_suspend Change-Id: I6dd7ea48d23b0fee74ecb9e93b53bfe36b0e8164 Signed-off-by: Monk Liu Reviewed-by: Christian König --- drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c | 9 ++++----- drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c | 6 ++---- 2 files changed, 6 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c index 2019e12..893daeb14 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_uvd.c @@ -1117,9 +1117,6 @@ static void amdgpu_uvd_idle_work_handler(struct work_struct *work) container_of(work, struct amdgpu_device, uvd.idle_work.work); unsigned fences = amdgpu_fence_count_emitted(&adev->uvd.ring); - if (amdgpu_sriov_vf(adev)) - return; - if (fences == 0) { if (adev->pm.dpm_enabled) { amdgpu_dpm_enable_uvd(adev, false); @@ -1139,11 +1136,12 @@ static void amdgpu_uvd_idle_work_handler(struct work_struct *work) void amdgpu_uvd_ring_begin_use(struct amdgpu_ring *ring) { struct amdgpu_device *adev = ring->adev; - bool set_clocks = !cancel_delayed_work_sync(&adev->uvd.idle_work); + bool set_clocks; if (amdgpu_sriov_vf(adev)) return; + set_clocks = !cancel_delayed_work_sync(&adev->uvd.idle_work); if (set_clocks) { if (adev->pm.dpm_enabled) { amdgpu_dpm_enable_uvd(adev, true); @@ -1159,7 +1157,8 @@ void amdgpu_uvd_ring_begin_use(struct amdgpu_ring *ring) void amdgpu_uvd_ring_end_use(struct amdgpu_ring *ring) { - schedule_delayed_work(&ring->adev->uvd.idle_work, UVD_IDLE_TIMEOUT); + if (!amdgpu_sriov_vf(ring->adev)) + schedule_delayed_work(&ring->adev->uvd.idle_work, UVD_IDLE_TIMEOUT); } /** diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c index fc5dcb2..c034b63 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vce.c @@ -300,9 +300,6 @@ static void amdgpu_vce_idle_work_handler(struct work_struct *work) container_of(work, struct amdgpu_device, vce.idle_work.work); unsigned i, count = 0; - if (amdgpu_sriov_vf(adev)) - return; - for (i = 0; i < adev->vce.num_rings; i++) count += amdgpu_fence_count_emitted(&adev->vce.ring[i]); @@ -362,7 +359,8 @@ void amdgpu_vce_ring_begin_use(struct amdgpu_ring *ring) */ void amdgpu_vce_ring_end_use(struct amdgpu_ring *ring) { - schedule_delayed_work(&ring->adev->vce.idle_work, VCE_IDLE_TIMEOUT); + if (!amdgpu_sriov_vf(ring->adev)) + schedule_delayed_work(&ring->adev->vce.idle_work, VCE_IDLE_TIMEOUT); } /** -- 2.7.4
