Created attachment 125386 --> https://bugs.freedesktop.org/attachment.cgi?id=125386&action=edit List of tests inducing systematic GPU lockups
Hi,
while performing Android Compatibility Test Suite run on marshamallow-x86 with mesa 12.0.1 I encountered systematic GPU lockups preceeded by full screen artifact, sometime "noise screen alike" and some others "vertical stripes".
The issue was observed on HD7750 and HD7950.
The pattern and list of the 12 dEQP-GLES2 tests causing systematic GPU lockups is the following:
dEQP-GLES2.functional.shaders.loops.while_{constant,uniform,dynamic}.{conditional,double}_continue_{vertex,fragment}
You can find in the attachments the dEQP GLES2 tests logs and some dmesg logs captured during these GPU lockups.
I am available to collect further logs, if you could provide me instructions, or to test patches and report back to help resolve the issue.
NOTE: I've already tried to define R600_DEBUG=nosb which in android-x86 has to be done in init.x86.rc before building the iso image, but then running a test plan with the aforementioned failed tests, I get again systematic GPU lockups.
