Description Guang Yang 2012-04-17 19:06:30 UTC 
System Environment:
--------------------------
Platform:        IVB/SNB/ILK
Kernel: (drm-intel-next-queued)17038de5f16569a25343cf68668f3b657eafb00e
Bug detailed description:
-------------------------
  -------------------------
   On IVB/SNB/ILK platform ,running gem_set_tiling_vs_blt of the
Intel-gpu-tools will fail.
  the error on the console is like this:
  testing untiled->tiled transisition:
  filling ring .. playing tricks .. checking .. done
  testing tiled->untiled transisition:
  gem_set_tiling_vs_blt: gem_set_tiling_vs_blt.c:204: do_test: Assertion `data[i] == i' failed.
  filling ring .. playing tricks .. checking .. Aborted (core dumped)
  
  Here is the GDB backtrace:
#0  0x00000037d4036415 in raise () from /lib64/libc.so.6
#1  0x00000037d4037d2b in abort () from /lib64/libc.so.6
#2  0x00000037d402ed0d in __assert_fail () from /lib64/libc.so.6
#3  0x0000000000401edb in do_test (tiling=1, stride=4096, tiling_after=0, stride_after=4096) at gem_set_tiling_vs_blt.c:204
#4  0x0000000000401fda in main (argc=<optimized out>, argv=<optimized out>) at gem_set_tiling_vs_blt.c:248

  With the log,I find that we rename gem_tiled_after_untiled_blt into gem_set_tiling_vs_blt,and here is one older fixed bug: 47990 about this case.

Sorry, I've extended the test to catch more bugs on gen3, but forgot to test it on later gens before committing. This failure should be fixed in intel-gpu-tools with

    tests/gem_set_tiling_vs_blt: fix on gen4+

btw: Please mark i-g-t failures as blocking the meta bug, not depending upon another failing i-g-t test, thanks.
