What is `mali-cmar-backend` process? is there any documents about it?

Feifan Qian

Hi experts,

I tried to modified the mali kernel driver to track which process has accessed the mali gpu, and I find a unique process "mali-cmar-backend":

```

[   64.274398] current->pid: 222, current->comm: mali-cmar-backe

```

What does this process do? Any one familiar with this?
