    Phoronix: New xf86-video-ati Release Planned With KMS

    The xf86-video-ati 6.12.0 X.Org driver was released in March of 2009. Since then there has been no significant releases of the ATI X.Org driver, but fortunately, a new release is on the way.The xf86-video-ati DDX driver has been at version 6.12.99 for quite a while now in the Git snapshots, but no release has been pushed...

      Great! So it looks like KMS for Radeon driver is ready for general use, is it? I'm curious how will KMS work with my multiseat environment with two R3xx cards.

        Yes and no. The graphical glitches got sorted out, but its performance right now is... abysmal to the point where it's simply not practical to enable it, even compared to UMS which is slow to begin with

          Yeah, there aren't that many apparent glitches/bugs with KMS and radeon right now. Performance is craptacular, so I doubt it will be the default setting anytime soon.

            Wrong.
            I still can't get a valid video signal through DVI->HDMI with my RV670. DVI->VGA works fine though.
            This happens only with KMS enabled.

              File a bug report in case you haven't done yet.

                Pretty disappointing to hear about the abysmal KMS performance ..

                  I can confirm this as well. With KMS enabled there's essentially no output on DVI after grub (as soon as the drive loads I assume).
                  With radeon.modeset=0 everything works.
                  This sucks, as I've understood that KMS is required for vsync to work with xv (to get tear free video)?

                  As Iäm a linux noob, please point me to where I should report this, and what I need to include in the bug report.

                  What is weird is that if I SSH to the box the X logs look fine, i.e correct EDID data is read from the projector etc and there are no errors.
                  I tried various radeon driver options without success.
                  I'm running 2.6.33 and latest from xorg-edgers ppa.

                  Should I just go out and buy a Nvidia to get my Mythbox running?

                    No, it's not required. KMS is only needed for a VSync'ed desktop. Xv with UMS is tear-free in non-composited desktops and in composited ones if you watch in fullscreen.

                      Works fine with my DVI screen (don't have HDMI to try though, and I never tried VGA for that matter either). I did have to make sure radeon was loading before kdm, otherwise I would get no signal.

                        Try to Plugin you Display on the other Output. If i connect my display at DVI-0 i have no signal but if i use DVI-1 all is fine.

                          With the latest kernel and xorg-edgers packages (probably the latest gits) 2D is very choppy. Firefox is unusable, Konqueror runs quite good, but overall 2D is much worse then without KMS.

                            I have KMS enabled for months now (9550 Radeon card), and I have to say I'm quite satisfied: desktop effects are working almost perfect, watching videos is excellent, my brother even plays Counter Strike, smaller memory footprint is also a benefit... Of course, I compile xf86-video-ati driver and mesa stack every once in a while from git.

                              The 9550 is quite an old card (I hasten to add I ran one happily using radeonhd across multiple installed distros until quite recently, because it simply can't cut the mustard for modern pc gaming)

                              The question is, what does this new driver do for more recent ati products? If anything...
