Subject: [PATCH 0/4] drm/ttm: Get rid of a number of atomic read-modify-write ops v3
Date: Tue, 6 Nov 2012 12:31:47 +0100 [thread overview]
Message-ID: <1352201511-6383-1-git-send-email-thellstrom@vmware.com> (raw)
A patch series for next that removes a substantial number of read-modify-write
operations from TTM command submission, in particular if TTM objects are used
to export objects to user-space. The only per-object atomic r-m-w operations
left during a typical execbuf call should be refcount up and down.
v2: Formatting fixes.
v3: Invert the return value of kref_get_unless_zero.
Add a comment in the commit message to patch 4 that it may be obsoleted.
