drm: amd: remove broken include path

2017-12-20T09:07:21+00:00

[ Upstream commit 655d9ca9ac075da1ef2a45012ba48a39f6eb1f58 ] The AMD ACP driver adds "-I../acp -I../acp/include" to the gcc command line, which makes no sense, since these are evaluated relative to the build directory. When we build with "make W=1", they instead cause a warning: cc1: error: ../acp/: No such file or directory [-Werror=missing-include-dirs] cc1: error: ../acp/include: No such file or directory [-Werror=missing-include-dirs] cc1: all warnings being treated as errors ../scripts/Makefile.build:289: recipe for target 'drivers/gpu/drm/amd/amdgpu/amdgpu_drv.o' failed ../scripts/Makefile.build:289: recipe for target 'drivers/gpu/drm/amd/amdgpu/amdgpu_device.o' failed ../scripts/Makefile.build:289: recipe for target 'drivers/gpu/drm/amd/amdgpu/amdgpu_kms.o' failed This removes the subdir-ccflags variable that evidently did not serve any purpose here.

drm/amdgpu: fix parser init error path to avoid crash in parser fini

[ Upstream commit 607523d19c9d67ba4cf7bdaced644f11ed04992c ] If we don't reset the chunk info in the error path, the subsequent fini path will double free.

drm/amdgpu: fix unload driver issue for virtual display

[ Upstream commit 3a1d19a29670aa7eb58576a31883d0aa9fb77549 ] Virtual display doesn't allocate amdgpu_encoder when initializing, so will get invaild pointer if try to free amdgpu_encoder when unloading driver.

drm/radeon: fix atombios on big endian

2017-12-05T10:24:34+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

drm/amdgpu: Potential uninitialized variable in amdgpu_vm_update_directories()

2017-12-05T10:24:34+00:00

commit 78aa02c713fcf19e9bc8511ab61a5fd6c877cc01 upstream. After commit ea09729c9302 ("drm/amdgpu: rework page directory filling v2") then it becomes a lot harder to verify that "r" is initialized. My static checker complains and so I've reviewed the code. It does look like it might be buggy... Anyway, it doesn't hurt to set "r" to zero at the start.

drm/amdgpu: potential uninitialized variable in amdgpu_vce_ring_parse_cs()

2017-12-05T10:24:34+00:00

commit 40a9960b046290939b56ce8e51f365258f27f264 upstream. We shifted some code around in commit 9cca0b8e5df0 ("drm/amdgpu: move amdgpu_cs_sysvm_access_required into find_mapping") and now my static checker complains that "r" might not be initialized at the end of the function. I've reviewed the code, and that seems possible, but it's also possible I may have missed something.
