    Add gem_fence_thrash test · 8f3f862b
    Chris Wilson authored
    This is a test case that overcommits fence registers between threads, which
    are copying from one fenced bo to another. In earlier versions of the driver
    this would cause excessive spinning as the first inactive (i.e. not in use
    by the GPU) would be used to service the next page. After all the fence
    registers had been allocated, in effect only the very first fence would then
    be used for all subsequent faults.
