Using the ARRAY_SIZE macro improves the readability of the code. Found with Coccinelle with the following semantic patch: @r depends on (org || report)@ type T; T[] E; position p; @@ ( (sizeof(E)@p /sizeof(*E)) | (sizeof(E)@p /sizeof(E[...])) | (sizeof(E)@p /sizeof(T)) ) Reviewed-by:

Add more generic function amdgpu_copy_ttm_mem_to_mem() that supports arbitrary copy size, offsets and two BOs (source & dest.). This is useful for KFD Cross Memory Attach feature where data needs to be copied from BOs from different processes v2: Add struct amdgpu_copy_mem and changed amdgpu_copy_ttm_mem_to_mem() function parameters to use the struct v3: Minor function name change Signed-off-by:

In amdgpu_cs_parser_init() in case of error handling amdgpu_ctx_put() is called without setting p->ctx to NULL after that, later amdgpu_cs_parser_fini() also calls amdgpu_ctx_put() again and mess up the reference count. Signed-off-by:

SR-IOV need to exchange some data between PF&VF through shared VRAM PF will copy some necessary firmware and information to the shared VRAM. It also requires some information from VF. PF will send a key through mailbox2 to help guest calculate checksum so that it can verify whether the data is correct. So check the data on the specified offset of the shared VRAM, if the checksum is right, read values from it and write some VF information next to the data from PF. Signed-off-by:

This enables old fence waiting before reservation lock is aquired which in turn is part of a bigger solution to deadlock happening when gpu reset with VRAM recovery accures during intensive rendering. Signed-off-by:

The AMDGPU_SCHED_OP_PROCESS_PRIORITY_OVERRIDE ioctls are used to set the priority of a different process in the current system. When a request is dropped, the process's contexts will be restored to the priority specified at context creation time. A request can be dropped by setting the override priority to AMDGPU_CTX_PRIORITY_UNSET. An fd is used to identify the remote process. This is simpler than passing a pid number, which is vulnerable to re-use, etc. This functionality is limited to DRM_MASTER since abuse of this interface can have a negative impact on the system's performance. v2: removed unused output structure v3: change refcounted interface for a regular set operation Signed-off-by:
