2017-02-09drm/amdgpu: shut up #warning for compile testingArnd Bergmann1-0/+2
My randconfig tests on linux-next showed a newly introduced warning: drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_create_restricted': drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:377:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp] Generally speaking, warnings about bad kernel configuration are not particularly helpful. We could enforce the selection of X86_PAT through Kconfig, so the driver cannot even be used unless it is enabled, or we could just rely on the runtime warning that is also there. In this version, I'm making the warning conditional on CONFIG_COMPILE_TEST, which shuts it up for me, but not people that may actually want to run the kernel as a compromize.

When GPU fails to resume we can not trust that value we write to GPU memory will post and we might get garbage (more like 0xffffffff on x86) when reading them back. This trigger out of range memory access in the kernel inside the vce resume code path. This patch use canonical value to compute offset instead of reading back value from GPU memory.

2017-01-31drm/exynos: g2d: prevent integer overflow inJoonyoung Shim1-1/+16
The size computations done in the ioctl function use an integer. If userspace submits a request with req->cmd_nr or req->cmd_buf_nr set to INT_MAX, the integer computations overflow later, leading to potential (kernel) memory corruption. Prevent this issue by enforcing a limit on the number of submitted commands, so that we have enough headroom later for the size computations. Note that this change has no impact on the currently available users in userspace, like e.g. libdrm/exynos. While at it, also make a comment about the size computation more detailed.

We were trying to print an error message if we timed out here, but the loop actually ends with "tries" set to UINT_MAX and not zero. Fix this by changing from tries-- to --tries. A for loop would actually be the most natural way to do this. My fix means we only loop 99 times instead of 100 but that's probably ok.

2017-01-31drm/exynos: use atomic helper commitInki Dae3-110/+39
This patch replaces specific atomic commit function with atomic helper commit one. For this, it removes existing atomic commit function and relevant code specific to Exynos DRM and makes atomic helper commit to be used instead. Below are changes for the use of atomic helper commit: - add atomic_commit_tail callback specific to Exynos DRM . default implemention of atomic helper doesn't mesh well with runtime PM so the device driver which supports runtime PM should call drm_atomic_helper_commit_modeset_enables function prior to drm_atomic_helper_commit_planes function call. atomic_commit_tail callback implements this call ordering. - allow plane commit only in case that CRTC device is enabled. . for this, it calls atomic_helper_commit_planes function with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

These bits sit outside the layer block itself, but in VOU control glue block. We currently set these bits up at CRTC initialization for once, and do not support disabling the layer. This patch creates a pair of functions zx_vou_layer_enable[disable] to be invoked from plane hooks .atomic_update and .atomic_disable to set up and tear down the layer.
