From: Andrey Grodzovsky <andrey.grodzovsky@xxxxxxx> Reserved VRAM is used to avoid overriding pre OS FB. Once our display stack takes over we don't need the reserved VRAM anymore. v2: Remove comment, we know actually why we need to reserve the stolen VRAM. Fix return type for amdgpu_ttm_late_init. v3: Return 0 in amdgpu_bo_late_init, rebase on changes to previous patch v4: rebase Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky at amd.com> Signed-off-by: Alex Deucher <alexander.deucher at amd.com> --- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 7 +++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_object.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 6 +++++- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.h | 1 + drivers/gpu/drm/amd/amdgpu/gmc_v6_0.c | 2 ++ drivers/gpu/drm/amd/amdgpu/gmc_v7_0.c | 2 ++ drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c | 2 ++ drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 2 ++ 8 files changed, 22 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c index 9e23d6f6f3f3..a160ef0332d6 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_object.c @@ -852,6 +852,13 @@ int amdgpu_bo_init(struct amdgpu_device *adev) return amdgpu_ttm_init(adev);
