[Dri-devel] Questions about current status of DRI
Hi guys, I've been busy for a while, but summer is approaching with the possibility of some spare time, so I have several questions about current status of DRI: 1. I could not find a link to the newer ViewCVS interface on the website - does it exist ? 2. Is anyone working on accelerated 3d for newer Radeons (R300, etc) ? 3. Can anyone tell me what changes are required in order to enable idle DRI for R300 and above ? (I.e. DRM module starts up, 2d commands go through DRM , but Mesa driver does software rendering). This is a question about DRI architecture, not hardware. I.e. if part of this functionality involves hardware that's changed in R300 it also falls in idle category. 4. Are there any examples of user-space applications accessing DRM, the same way Mesa driver does, but (hopefully) simpler ? I might have some success in figuring out CP sequences and present the result as a user-space library, but I doubt I will have time to dig inside Mesa. 5. I remember there was someone working to merge current GATOS code into DRI - did these changes made it into DRI CVS ? thank you very much !

The infamous CP microcode is needed. AFAIK, Benjamin Herrenschmidt got it from ATI. the BeOS driver has some r300 microcode in its sources... http://www.bebits.com/appver/2938 download the r5 source at look at CPMicroCode.h in the file... no idea what it is of course it might be 2d only or something wierd..

Yep, it matches the code I see in the DDK. So it appears that the only thing left to get 3d working is to find/verify packets for CP engine. best Vladimir Dergachev Dave. -- David Airlie, Software Engineer http://www.skynet.ie/~airlied / airlied at skynet.ie pam_smb / Linux DECstation / Linux VAX / ILUG person --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
