I want to measure the performance of 2 different framebuffer drivers,
and I am not sure what the process is.
Cairo-perf-trace seems great in that it will playback real display
history through the driver.

What I'm not sure of is how I can load/unload the framebuffer drivers so
cairo uses them. The system I am testing on[a BeagleBoneBlack dev
board] does not usually have XWindows running since I don't keep it
hooked up to a monitor - and I'm unclear on how the performance tool
determines which framebuffer to use when given the --xlib parameter.
I want to test the basic frame buffer driver[fbdev] against a copy of it
that has been slightly modified to use the neon functions of the Arm
processor[fbturbo https://github.com/ssvb/xf86-video-fbturbo ]
I feel like I'm probably just missing something obvious in how XWindows
functions and that there is a simple solution. So I figured I'd ask. :-)
