[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
