That's not necessary a good justification for the naming. What exactly was the original trace_amdgpu_cs_ioctl() doing?

That being said, it's used by gpuvis so I chose to not modify it. As for the new event: initially I named it "amdgpu_cs_parser_init", but since the intent is to mark the beginning of the amdgpu_cs_submit I've renamed it. Any suggestion for a better name?

amdgpu_cs_ioctl already exists but serves a different purpose. amdgpu_cs_ioctl2 marks the beginning of the kernel processing of the ioctl which is useful for tools to map which events belong to the same submission (without this, the first event would be the amdgpu_bo_set_list ones).
