From: jiadozhu <jiadong.zhu@xxxxxxx>
This is a standalone test case used for software mcbp on gfx9.
Build and open two consoles to run:
build/bin/vkpreemption s gfx=draws:1000000,priority:high,delay:0
build/bin/vkpreemption c gfx=draws:1000000,priority:low,delay:0
The result is printed on the console of the server side.
