drm/amdgpu: bypass lru touch for KIQ ring submission

2017-12-20T09:10:23+00:00

[ Upstream commit dce1e131dd4dc68099ff1b70aa03cd2d0acf8639 ] KIQ ring submission is used for register accessing on SRIOV VF that could happen both in irq enabled and irq disabled cases. Inversion lock could happen on adev->ring_lru_list_lock, while this operation is useless and just adds overhead in this use case.

drm/amdgpu: Use unsigned ring indices in amdgpu_queue_mgr_map

commit fa7c7939b4bf112cd06ba166b739244077898990 upstream. This matches the corresponding UAPI fields. Treating the ring index as signed could result in accessing random unrelated memory if the MSB was set.

drm/amdgpu: move UVD/VCE and VCN structure out from union

commit b43aaee69d4327d05e7624d9471c17d015b4d67d upstream. With the enablement of VCN Dec and Enc from user space, User space queries kernel for the IP information, if HW has UVD/VCE, the info comes from these IP blocks, but this could end up mis-interpret for VCN when they are in the union, the other way same when HW with VCN block.

drm/radeon: fix atombios on big endian

2017-12-05T10:26:36+00:00

commit 4f626a4ac8f57ddabf06d03870adab91e463217f upstream. The function for byteswapping the data send to/from atombios was buggy for num_bytes not divisible by four. The function must be aware of the fact that after byte-swapping the u32 units, valid bytes might end up after the num_bytes boundary. This patch was tested on kernel 3.12 and allowed us to sucesfully use DisplayPort on and Radeon SI card. Namely it fixed the link training and EDID readout. The function is patched both in radeon and amd drivers, since the functions and the fixes are identical. Signed-off-by: Roman Kapl Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
