[Mesa-dev] [PATCH] i965: Use updated kernel interface for accurate TIMESTAMP reads

2015-07-21 Thread Chris Wilson
I was mistaken, I thought we already had fixed this in the kernel a couple of years ago. We had not, and the broken read (the hardware shifts the register output on 64bit kernels, but not on 32bit kernels) is now enshrined into the ABI. I also had the buggy architecture reversed, believing it to be
