Still valid failure on WW08 execution with 4.10.0-rc8-drm-tip-qa-ww7-commit-e80b772+ on BXT-1-NOTEBOOK).
Comment 8 Chris Wilson 2017-03-14 17:02:44 UTC 
The test is a bit weak. It is asserting that it detects cache-line dirt when such detection is tricky.

    igt/prime_mmap_coherency: Reorder cache flushes to avoid excess pressure
    
    Flush the secondary buffer from the cpu cache before dirtying the cache
    for the primary to ensure a better chance of the primary buffer
    remaining in cache, causing the incoherency.
