From: Rob Clark <robdclark@xxxxxxxxxxxx> When many of the things using the GPU are processes in a VM guest, the actual client process is just a proxy. The msm driver has a way to let the proxy tell the kernel the actual VM client process's executable name and command-line, which has until now been used simply for GPU crash devcore dumps. Lets also expose this via fdinfo so that tools can expose who the actual user of the GPU is.
