deqp test failure pattern
failure mask for one test
another set of errors, with actual/original
Description Ilia Mirkin 2016-02-12 20:34:25 UTC
Created attachment 121724 [details] deqp test failure pattern I'm seeing the following failure pattern on *texture* dEQP tests. Only cube fails, and not 100% of them. All of these tests pass on nouveau/GK208, so it's not some really dumb texture completeness issue. It does seem like the only tests that pass are in the filter_mode subgroup (and all of those do seem to pass). So probably something with texture setup? Amusingly that test case group is TestCaseGroup(m_context, "filter_mode", "Test that filter modes have no effect"); oops :) I guess it has the effect of causing the tests to pass. By default, nearest/nearest is used for min/mag filters.

Related to #92579?

(In reply to Kenneth Graunke from comment #1) > Related to #92579? Don't know. But applying Neil's last patch just makes everything fail :)

Created attachment 121727 [details] failure mask for one test I checked a few and they all look like this. The hole at the top moves around a bit, but always this general square of fail inset into the image. Weird.

Created attachment 121728 [details] another set of errors, with actual/original If you use chrome, just start typing data:image/png;base64, and then paste the base64'd data after the ',' from the attachment -- no need to remove newlines/etc.
