Before killing the case,the machine is able to be login using ssh. But so long as we killed the case, the system hang.
This issue doesn't reproduce on Piketon platform.
The case intel_gpu_tool/gem_pread_after_blit has the same issue.
This impacts many cases and blocks QA's nightly testing. Eric/Zhenyu, who wanna take this?
The issue in intel_gpu_tool has fix. Now, so long as run the case glean/readpixPerf on HuronRiver the system hang, but it works well on Calpella platform.
Some cases such as divzero.c zbfunc.c bexact.c logicop.c and drawpix.c have the similar issue in oglc test suite.
On my system, "glean -r asdf -t readpixPerf -o" triggers a GPU reset and after a couple of flickers I ^C it and graphics is recovered.
yeah, sandybridge reset function works fine. Please test with drm-intel-next. We could close this hang bug if no more hang with that.
It still hangs on our Huron River with the latest drm-intel-next. We'll test the latest mesa.
The case readpixPerf has passed. And two cases in Oglc test suite still cause system hang: case divzero.c and fpstate.c.
should be related to this fix: commit 2b1469340bbf910469449354eeb5c02a9acfedba Author: Zhenyu Wang <zhenyuw@linux.intel.com> Date: Mon Dec 6 15:15:55 2010 +0800 i965: Fix GS state uploading on Sandybridge Need to check the required primitive type for GS on Sandybridge, and when GS is disabled, the new state has to be issued too, instead of only updating URB state with no GS entry, that caused hang on Sandybridge. This fixes hang issue during conformance suite testing. Closing this bug, and track the rest 2 oglconform hangs in separate bugs.
The hang issue disappeared.
