From 42cdf6f687daa1a1992db400e8311e1e49c787fb Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 26 Apr 2023 14:44:43 -0400 Subject: [PATCH] drm/amdgpu/gfx8: always restore kcq MQDs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Always restore the MQD not just when we do a reset. This allows us to move the MQD to VRAM if we want. v2: always reset ring pointer as well (Christian) Reviewed-by: Christian König Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c b/drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c index 5de44d7..2ae7f167 100644 --- a/drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c +++ b/drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c @@ -4651,15 +4651,13 @@ static int gfx_v8_0_kcq_init_queue(struct amdgpu_ring *ring) if (adev->gfx.mec.mqd_backup[mqd_idx]) memcpy(adev->gfx.mec.mqd_backup[mqd_idx], mqd, sizeof(struct vi_mqd_allocation)); - } else if (amdgpu_in_reset(adev)) { /* for GPU_RESET case */ - /* reset MQD to a clean status */ + } else { + /* restore MQD to a clean status */ if (adev->gfx.mec.mqd_backup[mqd_idx]) memcpy(mqd, adev->gfx.mec.mqd_backup[mqd_idx], sizeof(struct vi_mqd_allocation)); /* reset ring buffer */ ring->wptr = 0; amdgpu_ring_clear_ring(ring); - } else { - amdgpu_ring_clear_ring(ring); } return 0; } -- 2.7.4
