Subject: Patches to go on top of Michels page_flip_target patches.
Date: Sat, 17 Sep 2016 14:25:37 +0200 [thread overview]
Message-ID: <1474115139-25201-1-git-send-email-mario.kleiner.de@gmail.com> (raw)
Hi,
testing on "simulated" pre-DCE4 radeon hw (via setting the module
parameter radeon.use_pflipirq=0 to avoid use of pflip irqs) showed
we need some adjustments on top of Michel's page_flip_target patches
on these old asics.
Patch 2/2:
Essentially disabling the ability to flip anywhere in vblank on
pre-DCE4, either via hw programming or via software for pre-AVIVO.
Patch 1/2:
Also some small refinement i noticed was possible for that old
pageflip completion path with some functionality we added a couple
of releases ago.
So these should go into drm-next for Linux 4.9.
thanks,
-mario
