Subject: [PATCH 0/2] drm/i915: HPD IRQ storm detection fixes
Date: Thu, 25 Oct 2018 18:26:55 -0400	[thread overview]
Message-ID: <20181025222657.9241-1-lyude@redhat.com> (raw)

---- IMPORTANT -----
As a note: I have not had the customer who this second patch is for test
this yet, I'm sending this ahead of time to make sure this is something
that isn't too crazy for upstream to accept. I'm not planning on pushing
this after review until I've verified this actually fixes their
problems.
--------------------

This series contains a fix for a problem which is very difficult to
reproduce under normal circumstances without specialized testing
hardware, along with a fix that seems to be required for some especially
rebellious GM45 laptops.

  drm/i915: Fix NULL deref when re-enabling HPD IRQs on systems with MST
  drm/i915: Add short HPD IRQ storm detection for non-MST systems
