[RFC PATCH v1 00/16] Convert all ttm drivers to use the new reservation interface
This series depends on the previously posted reservation api patches.
2 of them are not yet in for-next-fences branch of
git://git.linaro.org/people/sumit.semwal/linux-3.x.git
The missing patches are still in my vmwgfx_wip branch at
git://people.freedesktop.org/~mlankhorst/linux
All ttm drivers are converted to the fence api, fence_lock is removed
and rcu is used in its place.
qxl is the first

[PATCH 00/17] Convert TTM to the new fence interface.
This series applies on top of the driver-core-next branch of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
Before converting ttm to the new fence interface I had to fix some
drivers to require a reservation before poking with fence_obj.
After flipping the switch RCU becomes available instead, and
the extra reservations can be dropped again. :-)
I've done at least basic

[PATCH 00/37] [RFC] revamped modeset locking
Hi all,
First thing first: It works, I now no longer have a few dropped frames every 10s
on my testbox here with the pageflip i-g-t tests.
Random notes:
- New design has per-crtc locks to protect the crtc input-side (pageflip,
cursor) for r/w and the output state of the crtc (mode, dpms) as read-only. It
also required completely revamped fb lifecycle management, those are now
refcounted
