drm/amdgpu: Don't warn on destroying a pinned BO

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

commit 456607d816d89a442a3d5ec98b02c8bc950b5228 upstream. The warning turned out to be not so useful, as BO destruction tends to be deferred to a workqueue. Also, we should be preventing any damage from this now, so not really important anymore to fix code doing this.

drm/amdgpu: Warn and update pin_size values when destroying a pinned BO

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

commit 15e6b76880e65be24250e30986084b5569b7a06f upstream. This shouldn't happen, but if it does, we'll get a backtrace of the caller, and update the pin_size values as needed. v2: * Check bo->pin_count instead of placement flags (Christian König) Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

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: Update pin_size values before unpinning BO

2018-06-19T18:50:56+00:00

At least in theory, ttm_bo_validate may move the BO, in which case the pin_size accounting would be inconsistent with when the BO was pinned. Cc: stable@vger.kernel.org Signed-off-by: Michel Dänzer Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Enable scatter gather display support

2018-05-15T18:43:49+00:00

Enables sg display if vram size <= THRESHOLD(256M); otherwise still use vram as display buffer. This patch fixed some potention issues introduced by change "allow framebuffer in GART memory as well" due to CZ/ST hardware limitation. v2: Change default setting to auto. v3: Move some logic from amdgpu_display_framebuffer_domains() to pin function, suggested by Christian. v4: Split into several patches. v5: Drop module parameter for now.

drm/amdgpu: Remove VRAM from shared bo domains.

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

This fixes an issue introduced by change "allow framebuffer in GART memory as well" which could lead to a shared buffer ending up pinned in vram. Use GTT if it is included in the domain, otherwise return an error. Signed-off-by: Samuel Li Reviewed-by: Alex Deucher Reviewed-by: Christian König Signed-off-by: Alex Deucher
