Description Mark Janes 2017-09-11 20:06:02 UTC

    
Comment 1 Mark Janes 2017-09-11 20:08:08 UTC
Roughly 10% of CTS test suite executions produce deadlocks, when running the suite in multiple threads.

For example, the suite has deadlocked with the following 2 tests stuck in execution:

  - ES2-CTS.functional.draw.draw_elements.line_strip.single_attribute
  - ES2-CTS.gtf.GL2FixedTests.mipmaps_interpolation.mipmaps_interpolation

Killing either of the test suite processes allows the other process to complete successfully.  The deadlocks stall execution indefinitely.
Comment 2 Mark Janes 2017-09-12 18:03:15 UTC
Other tests that hang:

ES2-CTS.functional.default_vertex_attrib.mat3.vertex_attrib_1f
ES2-CTS.functional.depth_range.write.zero_to_half
ES2-CTS.gtf.GL2FixedTests.buffer_color.buffer_color
Comment 3 Mark Janes 2017-10-27 18:48:36 UTC
It looks like we shipped this as far back as 17.1, so it is not a new regression for 17.3.
