      drm/i915: enable irqs earlier when resuming · 15239099
      Daniel Vetter authored
      We need it to restore the ilk rc6 context, since the gpu wait no
      requires interrupts. But in general having interrupts around should
      help in code sanity, since more and more stuff is interrupt driven.
      This regression has been introduced in

          drm/i915: Rearrange code to only have a single method for waiting upon the ring
      Like in the driver load code we need to make sure that hotplug
      interrupts don't cause havoc with our modeset state, hence block them
      with the existing infrastructure. Again we ignore races where we might
      loose hotplug interrupts ...
      Note that the driver load part of the regression has already been
      fixed in

          drm/i915: reorder setup sequence to have irqs for output setup
      v2: Add a note to the commit message about which patch fixed the
      driver load part of the regression. Stable kernels need to backport
      both patches.

      drm/i915: Increase the RC6p threshold. · 0920a487
      Stéphane Marchesin authored
      This increases GEN6_RC6p_THRESHOLD from 100000 to 150000. For some
      reason this avoids the gen6_gt_check_fifodbg.isra warnings and
      associated GPU lockups, which makes my ivy bridge machine stable.

          drm/i915/hdmi: Query the live connector status bit for G4x
      commit b0ea7d37
      Author: Damien Lespiau <damien.lespiau@intel.com>
      Date:   Thu Dec 13 16:09:00 2012 +0000
          drm/i915/hdmi: Read the HPD status before trying to read the EDID
      They reliably cause HDMI to not be detected on some systems (like my
      ivb or the bug reporters gm45). To fix up the very slow unplug issues
      we might want to fire up a 2nd detect cycle a few hundred ms after
      each hotplug. But for now at least make displays work again.
      I somewhat suspect that this is confined to HDMI connectors, since all
      the machines I have with DP+ outputs work correctly.
