dmesg.log

The following tests are failing on BXT, attached dmesg log for two tests, all failures have similar output and dmesg.

igt@gem_exec_schedule@out-order-blt
igt@gem_exec_schedule@out-order-bsd
igt@gem_exec_schedule@out-order-render
igt@gem_exec_schedule@out-order-vebox
igt@gem_exec_schedule@promotion-blt
igt@gem_exec_schedule@promotion-bsd
igt@gem_exec_schedule@promotion-render
igt@gem_exec_schedule@promotion-vebox


Steps to reproduce
========================================
1. Download and Install IGT suite.
2. go to intel-gpu-tools/tests/ folder
3. execute test ./gem_exec_schedule --run-subtest out-order-blt
4. execute test ./gem_exec_schedule --run-subtest out-order-bsd
5. execute test ./gem_exec_schedule --run-subtest out-order-render
6. execute test ./gem_exec_schedule --run-subtest out-order-vebox
7. execute test ./gem_exec_schedule --run-subtest out-promotion-blt
8. execute test ./gem_exec_schedule --run-subtest out-promotion-bsd
9. execute test ./gem_exec_schedule --run-subtest out-promotion-render
9. execute test ./gem_exec_schedule --run-subtest out-promotion-vebox

Expected output
====================================
Tests should be marked as pass


Actual output
=====================================

Below is the example only for out-rder-blt but other tests have a pretty similar output.

They are meant to be skip since they are tests for a feature that is not yet upstream.

Comment 9 Luis Botello 2017-02-23 23:59:24 UTC

Thanks for the clarification Chris, closing bug.
