    Anyone try this patch yet ?

    Nudge, perhaps we could contribute to the mainline kernel =)
    There are two mistakes one can make along the road to truth...not going all the way, and not starting.

    AIUI it's not usable yet, it's not sufficiently complete to run the psb driver on top of.

    Looks like good old Alan got a new toy he wants to play with, a DELL mini 10 !

    OK, so kernel-part of our beloved gma500 has been started. Now we need some more PowerVR power and we have a 100% supported piece of equipment! .

    Hi, Yves.

    It sounds NICE !!
    I hope I could backport this backlight module into current EMGD.. until the time when powerVR driver officially released. and if you could find any useful functions/pointers in pixmaps put surface for drm, please let me know !! I wanna also backport them into emgd_drm and/or emgd_fb.

    I feel honored to talk to you.
    Thanks.

    My apologies to all, it seems that after kwin detects a broken driver it just won't ever test again the driver capabilities. I had to edit kwinrc to get it to test again, and it works now both with or without EXANoComposite. Now I can even enable openGL rendering (instead of XRender), but it is too slow, even if it enables a lot of the effects that don't work using XRender. It also slows down everything openGl a lot (in particular glblur goes down to 6-7 fps instead of 15.5).

    that means we gain speed with EXANoComposite=false ? It would make sense, the option disables mmx/sse in EXA-code for compositing. It also means ubuntu ships xorg now with the option=true because the option should by default be false...

    I seem to gain some speed here with that option, so we could try it. My fumblings aside, it doesn't seem to break anything.

    What I had problems is that if I start X without xorg.conf it will try to use the fbdev driver and will lock. Could be because of what I have in grub.conf, enabling the 1366x768 framebuffer.

    Thanks to the link posted by Yves and to a bit of google searching I managed to compile the psb kernel module against kernel 2.6.38, but as soon as I try to test it I get in trouble with the issue described here http://code.google.com/p/gma500/issues/detail?id=26. I hope that the problem is related to a misconfiguration of my netbook, but at the moment I cant investigate further.

    The problems I fixed were:
    * function agp_flush_chipset() removed from kernel code;
    * functions (acquire|release)_console_sem() renamed to console_(lock|unlock)();
    * member fops->ioctl of structure drm_driver renamed to fops->unlocked_ioctl.

    The patch is available at https://gist.github.com/840787.

    Ciao,
    Nico

    Hi, fanum.

    did you join it ?
    if so, is there anything about remarkable topics ?

    Cheers.
