    drm/i915: Only unpin the default ctx object if it exists

    Since commit 691e6415c891b8b2b082a120b896b443531c4d45
    Author: Chris Wilson <chris@chris-wilson.co.uk>
    Date:   Wed Apr 9 09:07:36 2014 +0100

        drm/i915: Always use kref tracking for all contexts.

    we have contexts everywhere, and so we must be careful to distinguish
    fake contexts, which do not have an associated bo, and real ones, which
    do. In particular, we now need to be careful not to dereference NULL
    pointers.

    This is one such example, as the commit highlighted above failed to move
    the unpinning of the default ctx object into the real-context-only
    branch.

    drm/i915: Increase WM memory latency values on SNB

    On SNB the BIOS provided WM memory latency values seem insufficient to
    handle high resolution displays.

    In this particular case the display mode was a 2560x1440@60Hz, which
    makes the pixel clock 241.5 MHz. It was empirically found that a memory
    latency value if 1.2 usec is enough to avoid underruns, whereas the BIOS
    provided value of 0.7 usec was clearly too low. Incidentally 1.2 usec
    is what the typical BIOS provided values are on IVB systems.

    Increase the WM memory latency values to at least 1.2 usec on SNB.
    Hopefully this won't have a significant effect on power consumption.

    v2: Increase the latency values regardless of the pixel clock

The following patch fixes the problem for me on BDW:

http://patchwork.freedesktop.org/patch/35070/

I tested it using:

for i in vblank-vs-dpms-rpm vblank-vs-modeset-rpm vblank-vs-dpms-rpm-interruptible vblank-vs-modeset-rpm-interruptible; do sudo ./kms_flip --run-subtest $i; done
Comment 10 Paulo Zanoni 2014-10-17 19:22:31 UTC 
IGT patch committed. Closing bug.

When verifying, make sure you are running the most up-to-date IGT version, and that the patch is applied on it.

    tests/kms_cursor_crc: HSW/BDW only have square cursors

    When I look at cursor_size_ok() (from the Kernel's intel_display.c), I
    see that only 845g and i865g support non-square cursors, so SKIP the
    tests on HSW/BDW instead of failing them.

    This problem happened because support for non-square cursors was being
    developed for HSW/BDW, but it ended up not being merged due to a small
    problem and priority changes. Let's make those tests SKIP until we
    have proper support on the Kernel: after that, we can revert this
    patch.

    v2: Improve commit message.

Right. I was not reproducing the failure since I was running pm_rpm before kms_flip. If I just boot kms_flip, I can reproduce the bug. We were missing this patch too: http://patchwork.freedesktop.org/patch/35347/

With this, my BDW machine passes the test.
