PCI GART (?)

PCI GART (?)

[Michèl Alexandre Salim]

Hello,

This might not be the proper place to ask - my
apologies - but since it pertains to the Sony
Picturebook (C1VE - Crusoe) that people have been
discussing on this list anyway, I hope people don't
mind too much :)

I have RTFM but on the matter of enabling DRI for the
ATI Mobility video chipset, which on that notebook is
a PCI model, there is practically nil information. The
DRI website mentions using PCI GART, but there is no
option for that in the kernel. How do I enable this?

Currently running the XFree 4.0.2 from RH 7.0.90 (7.1
beta, Fisher) on top of my RH 7 + Ximian system and
when using aviplay it doesn't use any acceleration
features at all, consequently choppy display. The same
file plays much better in Windows.

Xdpyinfo shows that Xvideo and Xrender are both
loaded, so I presume they *should* work.

Thanks in advance,

Michel Salim

You need to get XFree86 CVS and really the right place to ask
is the XFree86 folks. The standard kernel doesnt include pcigart

Could be your aviplay doesnt support it.

Michel, FYI, PCI GART is a feature of the video chipset, not the host
bridge, and so is not directly related to the kernel (there's no generic
PCI GART driver like there is an AGP GART driver). AFAIK, the only PCI
GART implementation so far is for rage 128 (or derived, like the M3), and
is available in the "ati-pcigart-0-0-1-branch" DRI CVS branch. You need
to compile the DRM inside this X server version, not the kernel one.

Get the XFree ati.2 drivers from http://www.linuxvideo.org/gatos/,
and you will have hardware scaling. DRI is not supported yet.

xvinfo is a bit more informative about these things.
