Chris Wilson e1d8d774f3 overlay: Perf output redirection must be done after mmap() 
Effectively you choose to redirect the output of an event instead of
mmapping it directly - but the target must already be mmapped.

README 

This is a simple overlay showing current GPU activity. An asynchronous
overlay is used, rendered by the CPU to avoid introducing any extra work
on the GPU that we wish to monitor.

The x11-overlay backend requires xf86-video-intel 2.21.15 or later, with
SNA enabled.

As it requires access to debug information, it needs to be run as root.
