    drm/i915: split fb allocation and initialization v2

    If we use a stolen buffer, our probe callback shouldn't allocate a new
    buffer; we should re-use the one from the BIOS instead if possible.

    v2: fix locking (Jesse)

Bug detailed description:
-----------------------------
Igt/gem_seqno_wrap causes gpu hangs.

This is the first time to run igt test on Broadwell.

Error log:
[   49.694329] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[   49.694412] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[   49.694501] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[   49.694607] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[   49.694693] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Steps:
---------------------------
./gem_seqno_wrap

Needs rendercopy to work...
Comment 5 Guo Jinxian 2013-12-10 06:29:49 UTC 
The test had disabled.

[root@x-bdw01 tests]# ./gem_seqno_wrap

No render copy found for this gen, test is shallow!
