Bug 40928

Until now, the following Intel_gpu_tool cases has issue:

Hung case:
  gem_bad_batch 

Failure:
gem_bad_length: gem_bad_length.c:103: create0: Assertion `retval == 22' failed.

gem_mmap_gtt:   gem_mmap_gtt.c:87: gem_read: Assertion `ret == 0' failed.

This one should not run when using
$ make check
(it's in HANG in tests/Makefile.am instead of TESTS). Please ensure that
you run all these tests (idally with make check). Otherwise you might not
automatically pick up new tests I'm adding (on snb, a few more tests
should fail). I also suggest you upgrade your intel-gpu-tools repo at
least weekly.

Both known failures, fixes are in the works/under review.

Thanks for integrating this stuff with the qa workflow.

The case 'gem_linear_blits' time out(not finish about 1 hour) on IronLake mobile platform. But the issue doesn't appear on IronLake desktop. You man check if it occurs on your side.

Has that machine just 2GB of ram? In that case it's a bit expected
that this test takes forever, because it will heavily hit on swap.
I'll luck into tuning the test a bit better.

Yeah, the machines on which run this case time out are of 2G RAM. And I have tried the case again with a parameter which is smaller than the default one. It completed normally. So, I think, maybe we could update the test case.

I've updated the test to automatically limit the memory used to the
total available. If it's still taking too long, please complain.
Generally I aim for these tests to run a few minutes at most, i.e. I
think you could reduce your timeout to about 15 minutes.

A new Intel_gpu_tool cases has issue when run it at IvyBridge platform.

gem_tiled_pread:  Bad read [0]: 512 instead of 528 at 0x00000200 for read from 0x00000000 to 0x00100000, swizzle=bit9^10

This should be fixed with

    drm/i915: fix swizzling on gen6+

Please check whether you have that patch in your tree.

I find this issue with LINUX 3.1.1 kernel,which environment:
Kernel: (master)b48635635c1a696aea6423ec6c547c8c7bbf7aab
now this case can pass with the newest drm-intel-next.

Daniel,I have report a new i-g-t bug: Bug 43178

   A new Intel_gpu_tool cases has issue when run it at IVB/SNB/ILK platform.
   when run gem_exec_bad_domains ,we can find some error at dmesg, we test with the drm-intel-testing.
 Kernel: (drm-intel-testing)60f1358afca2d7778138c6dc187a3198f1a2425f

gem_exec_bad_domains resulting in errors is a know issue, I'll merge patch to fix this to -queued soon.

We don't do a stellar job of keeping this up-to-date, and now that i-g-t testing is well integrated into our QA workflow, this has outlived it's usefulness.
