    Phoronix: xf86-video-ati 6.10.0 Released

    AMD's Alex Deucher has announced the release of the xf86-video-ati 6.10.0 driver. This open-source ATI graphics driver update brings forth bi-cubic scaling on R300/400/500/690 chipsets, new ASICs are supported by this DDX driver, reduced X-Video tearing, and quite a few bug-fixes. The whole list of changes found in xf86-video-ati 6.10.0 can be read on the X.Org mailing list...

    can someone explain what is forth bi-cubic scaling?

    thanks

    ps: actually, what does this support mean in a normal day usage?

      I think this is talking about bicubic filtering in Xv. Whenever the driver displays video at a different resolution from the recording (eg when you are playing full screen or a big window) it uses the GPU to scale up the frames.

      If you don't filter while scaling you get big scaled up pixels in the displayed video and it looks crappy, so you have to filter. Bilinear filtering (the default for most HW, I think) gives you a slightly blurry image; bicubic filtering takes more processing but gives you a sharper image while still getting rid of the jaggy scaled up pixels.

        "to bring forth" is an English phrase that means something about the same as only "to bring" :P
        (Well, the explanation could be a bit better, but you get the point)

        bi-cubic scaling improves the picture quality when e.g. playing movies by using mathematical algorithms.

          Did they make xv work at all in r700 (HD4850)?

          Still tearing with the privative drivers .

            The Xv code is next on the list now that Alex has the 780 IGP parts working. We're still trying to figure out why the YUV-to-RGB shader for 6xx/7xx works in the test program but not in the driver code.

              Thanks for the prompt answer

                Compared to rc1 I have some flicker when X starts and it also starts slower. Haven't yet tried to watch videos.

                  Run

                  xrandr

                  to see it flicker

                    Should I do something else than just xrandr -q? 'cause that does not flicker one bit on this card..

                      The r6xx/r7xx Xv code in the radeonhd r6xx-r7xx-support branch works now for planar formats.

                        System still freezes after 20-30 minutes while using Firefox. This happens only when MigrationHeuristics greedy is not set. Hardware is a Mobility Radeon 9700.

                          The new driver works very well, though I'm getting some odd tearing in Xv.

                          Instead of the old diagonal line or triangle shape (which seems to be fixed!), now when there is motion in the image I get a repeated series of very shallow diagonal tears across the middle of the image, in a band. These seem almost horizontal until you look closely, but they are actually a series of very small diagonal tears.

                          This is on an X1550 PCIe. Xv tested in MythTV and in SMPlayer (mplayer).

                            I'm getting some strange behavior with 6.10.0. When I come back to the machine after a few hours (over night, etc) and move the mouse to wakeup the display, it wakes up for a second then blanks for a few secs and repeats a few more times. Total time varies between 10-30 secs (rough guess, seems a lot longer but I'm sure I'm just impatient)

                            My log contains a bunch of the following entries:
                            Disable CRTC 0 success
                            Blank CRTC 1 success
                            Disable CRTC 1 success
                            Enable CRTC 0 success
                            Unblank CRTC 0 success
                            Output 66 disable success
                            Enable CRTC 0 success
                            Unblank CRTC 0 success
                            Output 66 enable success
                            Output 66 disable success
                            Blank CRTC 0 success
                            My card is a X1650Pro. Running "xrandr -q" doesn't reproduce it. And it was just fine in 6.9.0. I'd like to submit a real bug report but not sure of the URL of the tracker. I'd also like to know what other info would be useful.

                            Thanks.

                              ^ Is anyone else having this issue?
