drm/amdgpu: Fix DEBUG_LOCKS_WARN_ON(depth <= 0) in amdgpu_ctx.lock

2019-01-13T08:50:57+00:00

[ Upstream commit c554206077428af56cc2e0314b86b41cd030458c ] If CS is submitted using guilty ctx, we terminate amdgpu_cs_parser_init before locking ctx->lock, latter in amdgpu_cs_parser_fini we still are trying to release the lock just becase parser->ctx != NULL.

drm/amdgpu: always recreate bo_list

2018-07-31T21:58:18+00:00

The bo_list handle is allocated by OP_CREATE, so in OP_UPDATE here we just re-create the bo_list object and replace the handle. This way we don't need locking to protect the bo_list because it's always re-created when changed. Signed-off-by: Christian König Reviewed-by: Chunming Zhou Signed-off-by: Alex Deucher
