    Phoronix: Will The Linux 2.6.39 Kernel Bring Graphics Magic?

    While the Linux 2.6.38 kernel isn't even released yet, it's likely to be released in the next day or two. After that and a few days of downtime, the merge window for the Linux 2.6.39 kernel will be opened. What features can one expect for the open-source Linux graphics support? As is usual these days, there's lots of expected changes...

    anything fancy for intel users?
    I see unrecoverable GPU lockups since 2.6.38-rc*

      pff, there's never "magic" revolutionary changes in graphics. Go away for a year, come back, millions of lines of code change, and you'll notice maybe 1 or 2 things that kinda work which didn't before. It's always slow and steady.

        You mean apart from whole families of devices being added?

        And of course you won't be including page-flipping which drastically speeded things up too

          Well, .39 will introduce support for a lot of new network (LAN/WLAN) chips, like the Realtek RTL8105E and Ralink RT5390 (along with very important fixes for Ralink RT3090). Quite a lot of the new AMD Fusion subnotebooks use those. So there's important stuff happening outside the graphics department.

            I hope for

            - even better R600 support (and the others, too)
            - especially power savings (there is, it works but still did not reach the consumption values I had with fglrx or catalyst (on W32 then).
            - and introduction of missing feeatures
            - aaand: something good for the VIA chipsets
            - aaand: something good for the ImgTec PowerVR chips

            Okay, it's not christmas but ... maybe ...

            But a nice and flawless 2.6.38 with responsiveness patches would be a nice birthday gift for me.

              Do you happen to know if the drm-radeon-testing branch is as good as drm-next?
              Because in Archlinux there is a good repository with mesa, xf86-video-ati and the kernel26-drm-radeon-testing updated to most recent git version every few days and I'd like to know if it is worth compiling another branch..

                There is so much tech jargon in this that the avarage Slashdot guru would have killed himself after reader only a quarter of all the Wikpedia entries about it.

                Anyway what I noticed most was that if you zoom out for a little and notice a bigger picture you are actually baffeled by what people do in a very short time. Sick.

                It is always the same with Linux; if you sort the advances on a year-after-year basis you can help but wonder how many awesomeness still need to be performed to actually gain some respectable desktop marketshare

                  I thought GraphicsMagick was a userspace component

                    The drm already has support for acceleration (2D/3D/Xv, etc.) on cayman. Barring possible drm bugs, the only missing bits are finishing up the userspace side. As noted previously, there is work in progress EXA/Xv code available in the cayman_accel branch of xf86-video-ati.

                        In regards to the Linux 2.6.39 kernel, I received a note over the weekend from a reader that said, "pls report about the changes in drm-next. i tested it with several mesa and libdrm git versions. with the drm-next kernel instead of stock 2.6.38 kernel fps in heroes of newerth with full details went from 10 to 30 on and hd4850. on windows with latest drivers and opengl renderer 37 fps. thats almost over 75 percent performance. even lightsmark 2008 went from 50 to 97 fps.i did not bisect the commits in drm-next cause i dont wanna compile so many kernels. im using colortiling pageflipping swapbuffers off and metacity." This Phoronix reader, Julius Von Kohout, additionally mentioned "and fyi everything rendered correctly. in general i reach about 70% of fglrx...awesome nexuiz went from 20-50 to 100-200 fps."

                        I did run a few quick tests last night on an AMD RV730 graphics card with Mesa/DDX Git and the latest from the drm-next tree. However, at least when Compiz is enabled and not disabling the SwapBuffersWait option, there wasn't any major change when going from the Linux 2.6.38 Git to the drm-next kernel.
                        Has someone else confirmed that this guy is not under drug effects?

                          Well that's exactly what Michael is going to test, isn't he?

                            Not to turn this thread into market share bafflegab but I really think Unity (maybe Gnome 3 too) makes the Linux desktop modern and shine compared to osx/win7. I mean Unity the one a year from now - not the one released this spring which is mainly a stopgap solution (but still cool). A good office suit and Wayland would push it even further, not to mention full GL3.3 support - these are coming too - but too slowly.

                              Hmm, yeah...hard to confirm what a user said without doing what he said he did.
