Subject: [PATCH 00/36] kms locking rework
Newsgroups: gmane.comp.video.dri.devel
Date: Thursday 10th January 2013 20:47:41 UTC (over 4 years ago)
Hi all,

Concurrent EDID reads and pageflips ftw!

Changes since the rfc:
- radeon/ttm/exynos prep patches/fixes merged.
- arm driver patches at least compile-tested.
- error handling fixed in a few cases, all spotted by Richard Wilbur,
- radeon/nouveau tested on one card each, didn't blow up right away.
- i-g-t extended to cover the corner-cases, seems to hold up.
- DocBook updated as a new patch on top.
- one more patch to teach the fb helpers manners and not interfere so much
with
  i-g-t tests.

Imo this is ready for inclusion, so (especially driver maintainers) please
review and test.

Yours, Daniel
