xfree-drm on rage128 with AGP?

[Mortalis]

I have followed all the instructions to get drm working on rage128 hardware (Thanks to the authors). Initially, I had AGP mode turned on in my XF86Config-4 file and using a depth of 16 casued X to be unusable (X was using 99% of the CPU according to top), but glxinfo reported rendering was on. Using a depth of 8, would give a usable X environment, but no direct rendering. Eventually, I decide to force PCI mode and this seems to have solved the problem. I can use a depth of 16 and have a very usable X environment with direct rendering on.

So, things are working okay now, but it would be nice to be able to use the card in AGP mode. Anbody had any luck with this card, drm, and AGP?

My machine is a G4 350 w/AGP in case anybody is interested.

Thanks

I had the very same problem: After a system upgrade which also among many other things upgraded xfree-drm- 4.3.0-r2 to xfree-drm- 4.3.0-r3, xfree stopped working properly, cpu usage shot up to 99% when starting x and everything slowed down to a crawl. I solved the problem (after many, many hours) by simply downgrading to xfree-drm4.3.0-r2. I also use an ATI 128 PRO/AGP with 16MB. Keep in mind that your video card should have at least 16MB in order to be able to use DRI. Here's my /etc/X11/XF86Config-4 for your reference, should come in handy since it shows all the necessary modules etc. :

Thanks c_kuzmanic. Downgrading fixed my problems and I am now getting about 600 FPS in glxgears.

Sorry for the delay, I just moved to a new state and just got my computer and internet service setup today.
