Subject: Fixing the i915 lock ordering
Date: Mon, 9 Mar 2009 18:33:49 -0700 [thread overview]
Message-ID: <1236648831-18230-1-git-send-email-eric@anholt.net> (raw)
Here's a new patch series with a proposed fix for two of the paths
with lock ordering problems in i915. If these look OK (in particular GTT
pwrite, which is the most important performance path), I'll work on
resolving the non-GEM issue and figuring out what we want to do about
execbuffers (either this plan, or krh's patch, or something with
get_user_pages and kmap).
