Not yet, but it is on the todo list.

On the other hand it sounds like a good beginners task if somebody wants to get
his hands dirty. I'm glad to help and point out the right place in the sources
if somebody volunteers.

At this moment we have working DRI3 setup (without Present for Radeon).

Is there any effort to port VDPAU to DRI3?

Shouldn't this be responsibility of the code that implements the vdpau API?
Maybe it should attempt to remap the MSC counters to system time, and smooth
out the differences. (Sorry I don't know anything about Mesa internals.)

IMO this issue does make the Mesa vdpau implementation very unreliable, and at
least for me it has caused a lot of problems.

Now we have DRI3, is here some code to test? Or we should test this patch?

Attempt at making DRI2 MSC counter consistent between CRTCs

Here's an attempt at making the DRI2 MSC counter per-window instead of
per-CRTC. I couldn't quite make it work, but maybe someone can run with this
and finish it.

I think this is because the DRI2 MSC counters differ between CRTCs, so a DRI2
buffer swap or MSC wait times out.

AFAICT it might be tricky to fix this, at least without DRI3.
