hi,
this is probably a FAQ, but I was wondering if at this stage it is
possible to get an accelerated OpenGL app running in Linux, without
having X?
Basically, I have implemented a dedicated display system for Xen (quite
similar in spirit to Quartz on OSX), so I do not need X, and since I am

Which driver are you using ?
The ATI fglrx one. I am using this with Xen, and I have not yet been
able to make r300 work.

hi,
I am trying to upload a video stream as 32x32 tiles to an OpenGL
texture, to see how many I can move per unit of time.
Does anyone know what the internal texure format of the ATI r350 is, or
where I can find this info?
I seem to get better numbers with BGRA 8bit than with ARGB 8bit.
thanks,
By the way, though I did not manage to get r300 running with Xen yet,
the DRM module needed these changes, or the machine would crash:

Hi Jacob,
Could you repost your patch with diff -u option ? it is a bit
easier to read.
Thank you !
Yes, here it goes. See attachment. It may need more #ifdefs, I have not
tried running it on straight x86.

I believe xen has a mode where you can assign hardware exclusively to
a user kernel. You'll need to do that and then run apg/drm/mesa all in
the same user kernel. Without that I think you need changes to xen or
drm. This is just a guess based on the log, I have not tried running

hi,
yes this is likely to do with Xen,
hi,
after getting r300 working on my Radeon 9600SE under Linux, I am trying
to make the same thing happen under Xen (in domain0).
However, I get the following error when loading drm.ko:

This means you have old Xorg code. You need to compile new one from CVS.
Hmm, apparently the 'make install' had not nuked all of my old X11
binaries. Now it

Will version 6.8.1.902 (from Gentoo) be recent enough?

Well yes. For radeon and r200 drivers (and apparently savage), you need
the freedesktop drm, since the one from the r300 driver is too old. For
the r300 driver, you need the r300 drm, as
