Radeon R5xx 3D programming guide releasedRadeon R5xx 3D programming guide releasedPosted Feb 24, 2008 23:27 UTC (Sun) by beoba (guest, #16942)Parent article: Radeon R5xx 3D programming guide released
Does anyone happen to know if they intend to release similar docs for the current R600 series? (Used in HD2xxx and HD3xxx cards)

Radeon R5xx 3D programming guide released Posted Feb 24, 2008 23:32 UTC (Sun) by beoba (guest, #16942) [Link] Semi-answer to my own question: Found a list of supported models here. Looks like the newest thing in that list is the HD2900 series (ie no HD3xxx).

It's nice to be able to tell the differences in memory bandwidth and clock speeds and other features. It often helps when picking out cards. A old example is the fact that for the R200 series cards the fastest one you could get was the 8500. The later ones, like the 9200, were actually designed more for cost effectiveness then performance.

Radeon R5xx 3D programming guide released Posted Feb 25, 2008 7:49 UTC (Mon) by eru (subscriber, #2753) [Link] From the page you linked to:(http://wiki.x.org/wiki/radeonhd#head-cc89624fd96105127892119323e209b3d80e137d)The following subsystems have not been implemented yet or show some limitations: In other words, currently it seems to be little more than a dumb framebuffer. Hopefully now that documents have been released, this changes for the better. I wish I could help, but I lost the track in video hardware programming about the time VGA came along...
Radeon R5xx 3D programming guide released Posted Feb 25, 2008 8:58 UTC (Mon) by daniels (subscriber, #16193) [Link] Yes, this is just in the radeonhd driver. The mainline radeon driver supports textured video, 2D and some minimal Render acceleration for everything up to r5xx, as well as dual-link DVI and scaling for LVDS.
Radeon R5xx 3D programming guide released Posted Feb 25, 2008 9:02 UTC (Mon) by rankincj (subscriber, #4865) [Link] Hmm, that render acceleration for the R500 only applies to EXA, doesn't it? I certainly saw no evidence of render acceleration being enabled with XAA. (And I did check the Xorg.0.log file.)
(Oops, I meant render acceleration for R300, not R500.) (NT). Posted Feb 25, 2008 9:04 UTC (Mon) by rankincj (subscriber, #4865) [Link] Yup, "no text here".
Radeon R5xx 3D programming guide released Posted Feb 26, 2008 5:16 UTC (Tue) by njs (subscriber, #40338) [Link] All X drivers are transitioning to using EXA exclusively; the only reason I know of to stick with XAA is if your card's EXA support is less stable than the older XAA support. That is unlikely to be the case when using brand-new drivers for previously unsupported hardware :-). I'd just turn on EXA. (And if things break, then file bugs and maybe drop back to unaccelerated mode, I guess.)
Radeon R5xx 3D programming guide released Posted Feb 25, 2008 1:59 UTC (Mon) by tbrownaw (guest, #45457) [Link] Information covering the 3D side of the R600 series is still being worked on but is expected in about one month. (Second paragraph, last sentence.)
Radeon R5xx 3D programming guide released Posted Feb 28, 2008 5:33 UTC (Thu) by agd5f (guest, #50412) [Link] We are planning to release 3D information for R6xx next.
