Cool, I'll take a look at the XFree tree when I get back to work,
just to give people a quick idea of what I want initially, I want to use
the hardware flipping as opposed to the blt we do now, and the i815 has
synchronous flipping by default (the async doesn't work properly - errata
to spec) whi
Just a quick follow-up to this. It looks like Arjan's patch comes from
XFree86 CVS, which got a bunch of i830 updates from Keith and David Dawes
a few days ago (which explains the "KW" comments in Arjan's patch). I
assume we'll get these into DRI with the next sync-up. Just another
example of th

You would delay rendering from that ring. There are 2 rings on i810
(Only one gets used by XFree/DRM).
Depending on what you are trying to achieve, that may be what you want.
If you used an interrupt to indicate vb

I fully expect that there's something that I'm missing, but shouldn't

FYI, I noticed this recent patch from Arjan van de Ven from lkml. It's
got page flipping and user-defined interrupts for i830 (for 2.4):

Out of curiosity, I just downloaded the i810/i815 specs. At first glance
I don't see why yo

That's quite surprising to me.
