drm/amdgpu: set COMPUTE_PGM_RSRC1 for SGPR/VGPR clearing shaders

2018-05-01T19:58:25+00:00

commit 75569c182e4f65cd8826a5853dc9cbca703cbd0e upstream. Otherwise, the SQ may skip some of the register writes, or shader waves may be allocated where we don't expect them, so that as a result we don't actually reset all of the register SRAMs. This can lead to spurious ECC errors later on if a shader uses an uninitialized register.

drm/amdgpu: Fix PCIe lane width calculation

2018-04-24T07:36:35+00:00

commit 41212e2fe72b26ded7ed78224d9eab720c2891e2 upstream. The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere. Port of the radeon fix to amdgpu.

drm/amdgpu: Fix always_valid bos multiple LRU insertions.

2018-04-24T07:36:35+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/dce: Don't turn off DP sink when disconnected

2018-03-21T11:06:43+00:00

commit 7d617264eb22b18d979eac6e85877a141253034e upstream. Turning off the sink in this case causes various issues, because userspace expects it to stay on until it turns it off explicitly. Instead, turn the sink off and back on when a display is connected again. This dance seems necessary for link training to work correctly.

drm/amdkfd: Fix memory leaks in kfd topology

2018-03-19T07:42:54+00:00

[ Upstream commit 5108d768408abc80e4e8d99f5b406a73cb04056b ] Kobject created using kobject_create_and_add() can be freed using kobject_put() when there is no referenece any more. However, kobject memory allocated with kzalloc() has to set up a release callback in order to free it when the counter decreases to 0. Otherwise it causes memory leak.
