From db2aad036e77100e04a96c67f65ae7d49fb538fb Mon Sep 17 00:00:00 2001 From: Le Ma Date: Thu, 25 Jan 2024 12:00:34 +0800 Subject: drm/amdgpu: move the drm client creation behind drm device registration This patch is to eliminate interrupt warning below: "[drm] Fence fallback timer expired on ring sdma0.0". An early vm pt clearing job is sent to SDMA ahead of interrupt enabled. And re-locating the drm client creation following after drm_dev_register looks like a more proper flow. v2: wrap the drm client creation Fixes: 1819200166ce ("drm/amdkfd: Export DMABufs from KFD using GEM handles") Signed-off-by: Le Ma Reviewed-by: Felix Kuehling Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index cc69005f5b46..971acf01bea6 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -2255,6 +2255,10 @@ retry_init: if (ret) goto err_pci; + ret = amdgpu_amdkfd_drm_client_create(adev); + if (ret) + goto err_pci; + /* * 1. don't init fbdev on hw without DCE * 2. don't init fbdev if there are no connectors -- cgit From 93bafa32a6918154aa0caf9f66679a32c2431357 Mon Sep 17 00:00:00 2001 From: Prike Liang Date: Tue, 16 Jan 2024 19:10:45 +0800 Subject: drm/amdgpu: skip to program GFXDEC registers for suspend abort In the suspend abort cases, the gfx power rail doesn't turn off so some GFXDEC registers/CSB can't reset to default value and at this moment reinitialize GFXDEC/CSB will result in an unexpected error. So let skip those program sequence for the suspend abort case.

So, make damage clips support configurable and disable it by default for PSR-SU displays.
