drm/amdgpu: Partially revert "drm/amdgpu: update drm_display_info correctly when the edid is read"

2022-12-08T10:23:02+00:00

[ Upstream commit 602ad43c3cd8f15cbb25ce9bb494129edb2024ed ] This partially reverts 20543be93ca45968f344261c1a997177e51bd7e1. Calling drm_connector_update_edid_property() in amdgpu_connector_free_edid() causes a noticeable pause in the system every 10 seconds on polled outputs so revert this part of the change.

drm/amdgpu: update drm_display_info correctly when the edid is read

2022-12-08T10:23:02+00:00

[ Upstream commit 20543be93ca45968f344261c1a997177e51bd7e1 ] drm_display_info is updated by drm_get_edid() or drm_connector_update_edid_property(). In the amdgpu driver it is almost always updated when the edid is read in amdgpu_connector_get_edid(), but not always. Change amdgpu_connector_get_edid() and amdgpu_connector_free_edid() to keep drm_display_info updated.

drm/amdgpu: Check BO's requested pinning domains against its preferred_domains

2022-08-25T09:17:24+00:00

commit f5ba14043621f4afdf3ad5f92ee2d8dbebbe4340 upstream. When pinning a buffer, we should check to see if there are any additional restrictions imposed by bo->preferred_domains. This will prevent the BO from being moved to an invalid domain when pinning. For example, this can happen if the user requests to create a BO in GTT domain for display scanout. amdgpu_dm will allow pinning to either VRAM or GTT domains, since DCN can scanout from either or. However, in amdgpu_bo_pin_restricted(), pinning to VRAM is preferred if there is adequate carveout. This can lead to pinning to VRAM despite the user requesting GTT placement for the BO. v2: Allow the kernel to override the domain, which can happen when exporting a BO to a V4L camera (for example).
