    tests/gem_fence_trash: make threaded tests more through-rough · 0a8bfbf7
    Daniel Vetter authored
    With this at least the y-tiled test reliably fails on my machines, but
    x-tiled still passes on some. More ideas to tune this highly welcome.
    
    v2: Fill cpu caches with data for each newly allocated bo. This seems
    to do the trick on my snb here _really_ reliably. So apparently the
    backsnoop for llc gtt writes is the crucial ingredient here to make
    the test fail.
    
    While at it, also stop leaking mmap space.
    
    v3: Fixup commit message.
