drm/amdgpu: Fix always_valid bos multiple LRU insertions.

2018-04-24T07:34:15+00:00

commit a20ee0b1f8b42e2568f3a4408003d22b2dfcc706 upstream. If these bos are evicted and are in the validated list things blow up, so do not put them in there. Notably, that tries to add the bo to the LRU twice, which results in a BUG_ON in ttm_bo.c. While for the bo_list an alternative would be to not allow always valid bos in there, that does not work for the user fence. v2: Fixed whitespace issue pointed out by checkpatch.pl Signed-off-by: Bas Nieuwenhuizen Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: check ring being ready before using

2017-07-05T12:40:23+00:00

[ Upstream commit c5f21c9f878b8dcd54d0b9739c025ca73cb4c091 ] Return success when the ring is properly initialized, otherwise return failure. Tonga SRIOV VF doesn't have UVD and VCE engines, the initialization of these IPs is bypassed. The system crashes if application submit IB to their rings which are not ready to use. It could be a common issue if IP having ring buffer is disabled for some reason on specific ASIC, so it should check the ring being ready to use. Bug: amdgpu_test crashes system on Tonga VF.

drm/amdgpu: validate size and offset of user fence BO

2016-09-14T19:10:43+00:00

We need to validate the offset to make sure that we don't write after the BO. Additional to that a page should be enough and can make address space handling much easier. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
