Description Guo Jinxian 2014-05-05 07:20:35 UTC 
*System Environment:
--------------------------
Platform: PNV
kernel: 
-nightly: 08ce6614d07dd1e426109672a5e323317c8d6ec7(fails)
-queued: e5c03ca362819ba8ffbe5674340b61b9cd75de8f (fails)
-fixes: 9bbfd20abe5025adbb0ac75160bd2e41158a9e83 (fails)


 *Bug detailed description:
-----------------------------
Subcases plane-position-covered-pipe-A-plane-1 and plane-position-hole-pipe-A-plane-1 of igt/kms_plane cost long time to execute, the test still didn't finish after 30 minutes.

Output:
[root@x-pnv2 tests]# date;./kms_plane --run-subtest plane-position-covered-pipe-A-plane-1;date
Mon May  5 15:48:50 EDT 2014
IGT-Version: 1.6-gc864279 (i686) (Linux: 3.14.0_drm-intel-next-queued_e5c03c_20140504+ i686)

 *Reproduce steps:
---------------------------- 
1. ./kms_plane --run-subtest plane-position-covered-pipe-A-plane-1
Comment 1 Todd Previte 2014-05-13 19:40:33 UTC 
So the test is stuck and has to be exited manually? Or does it eventually finish? I don't have a PNV system to investigate this on, unfortunately, so I'll need you to provide more information here.

1) Where is the test getting stuck? Are there any error messages displayed?
2) Any messages in dmesg? If so, please provide the dmesg log
3) Are the results identical between the different kernels or do they all fail in the exact same manner?

The test only can be exited manually, I tried to run the case more than 106m, it still unable to finish

time ./kms_plane --run-subtest plane-position-covered-pipe-A-plane-1

There isn't any error message on screen, I don't know where is the test getting stuck.

Please check dmesg in attachment

According the output and screen shows, they all fail in the exact same manner

Comment 4 Daniel Vetter 2014-05-15 14:46:59 UTC 
I bet this is just another piece of fallout from the broken igt_kms infrastructure. Pipe A won't work on PNV with just lvds, and there's nothing in the VGA port. See bug https://bugs.freedesktop.org/show_bug.cgi?id=75079
