Hi mark.a.janes@intel.com :

Could you tell us which info you need for this bug since i saw that you change the status of this bug to NEEDINFO.

Thanks
Comment 5 Mark Janes 2016-01-15 11:14:03 UTC
I don't have that test case in my deqp runs.  Can you provide the commit you are using for the dEQP test suite?
Comment 6 Annie 2017-02-10 22:39:00 UTC
Dear Reporter,

This Mesa bug has been in the "NEEDINFO" status for over 60 days. I am closing this bug based on lack of response but feel free to reopen if resolution is still needed. Please ensure you're supplying the correct information as requested.

Thank you.

Reopen this bug, since these cases also fails on BXT platform
The following test cases are failing:

deqp-gles2@functional@texture@vertex@cube@filtering@linear_mipmap_linear_linear_clamp		
deqp-gles2@functional@texture@vertex@cube@filtering@linear_mipmap_linear_linear_mirror

Configuration: 
Apollo Lake NUC
Platform: BOXNUC6CAYH
Processor: Intel Celeron J3455 CPU, quad-core, 1.5 GHz (2.3 GHz burst)
GPU: Intel HD Graphics 500

more information
These tests are in android dEQP CTS failurelist /cts/master/src/gles2-failures.txt
but they are not tracked as Google internal testcase bugs or hardware issues.
Not sure if it is mesa bug or not.

Comment 9 Kenneth Graunke 2018-03-13 06:11:37 UTC
I suspect this is an issue with the test.  GLES 3.0 enabled seamless cube map filtering by default, while GLES 2.0 didn't.  But since GLES 2.0 can be legally and silently promoted to 3.0, it's basically undefined whether it's enabled.  There are comments in some of the tests that they try and avoid corner/edge pixels that would hit this undefined behavior, but...the failures are all a single pixel at the very corner.

Notably, these two tests begin to pass if we disable seamless cubemap filtering (which we can't reasonably do):

dEQP-GLES2.functional.texture.vertex.cube.filtering.linear_mipmap_linear_nearest_clamp
dEQP-GLES2.functional.texture.vertex.cube.filtering.linear_mipmap_linear_nearest_mirror

These two continue failing:

dEQP-GLES2.functional.texture.vertex.cube.filtering.linear_mipmap_linear_nearest_repeat
dEQP-GLES2.functional.texture.vertex.cube.filtering.linear_mipmap_linear_linear_repeat

Notably, i965 passes the dEQP-GLES3 versions of the same tests.  I'm not aware of us doing something different for GLES2 and GLES3, so my guess is some bug fix to the tests didn't get copy and pasted back to the older GLES2 test.

More importantly, these are not in the Android CTS mustpass list, which means Google doesn't require them.  If Google doesn't think it's reasonable to require graphics vendors to pass these tests, and neither does Khronos, I'm inclined to agree and not spend any effort fixing them.  I think you should change how you're running the test suite to only run tests in the mustpass list.
