Comment 2 Chris Wilson 2014-10-11 16:04:03 UTC

Also fails here on my byt. Not yet convinced this is an igt bug.

Comment 3 Chris Wilson 2014-10-13 10:44:59 UTC

Indeed passes on ivb/hsw, and on byt with i915.enable_ppgtt=1.

Comment 4 Mika Kuoppala 2014-10-23 15:36:29 UTC

Please submit result of:

# cat /sys/kernel/debug/dri/0/i915_wedged

After the failed test.

Test still fails, but dmesg error unable to reproduce. the value about i915_wedged is 0.

    igt/gem_concurrent_blit: Only read back a few GTT values

    Due to the nature of the test, we can be reasonably sure that it is
    either all copied or not. So we can sacrificing testing the entire
    buffer for the expected value in order to speed up the test by only
    testing along the diagonal.

Comment 7 Chris Wilson 2014-11-10 07:29:55 UTC

That bisect result is meaningless.

Comment 8 Daniel Vetter 2014-11-20 16:06:30 UTC

Please double-check the bisect by reverting it. Likely this is an unstable testcase, so please double-check that the last good commit is _really_ good.

Revert commit 3e766b8255efb6c994e6501be2af44b4bdc4d191 on latest igt (d8078911f63494eba67f8f07ffb56c4bdeae7bc9), the result is timeout(bug 84354)

Comment 10 Chris Wilson 2014-11-21 08:44:51 UTC

Did you run with i915.enable_ppgtt=2? The testcase is valid. It is not an igt bug.

Comment 11 Guo Jinxian 2014-11-27 05:39:45 UTC

Similar dmesg failure reproduced while running tests below on IVB.
