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: add a custom GTT memory manager v2

Only allocate address space when we really need it. v2: fix a typo, add correct function description, stop leaking the node in the error case. Signed-off-by: Christian König Reviewed-by: Alex Deucher Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

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

drm/amdgpu: mark symbols static where possible

2016-09-14T19:10:37+00:00

We get a few warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/cz_smc.c:51:5: warning: no previous prototype for 'cz_send_msg_to_smc_async' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/cz_smc.c:143:5: warning: no previous prototype for 'cz_write_smc_sram_dword' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/iceland_smc.c:124:6: warning: no previous prototype for 'iceland_start_smc' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:3926:6: warning: no previous prototype for 'gfx_v8_0_rlc_stop' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/amdgpu_job.c:94:6: warning: no previous prototype for 'amdgpu_job_free_cb' [-Wmissing-prototypes] .... 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'.

drm/amdgpu: change job->ctx field name

2016-09-12T22:12:17+00:00

job->ctx actually is a fence_context of the entity it belongs to, naming it as ctx is too vague, and we'll need add amdgpu_ctx into the job structure later. Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher
