    Phoronix: Linux 2.6.34-rc1 Kernel Is Out w/ New Features

    Following a two week merge window following the release of the Linux 2.6.33 kernel, Linus Torvalds has announced the first release candidate for the next kernel, to be known as the Linux 2.6.34 kernel.Of a lot of interest to us (and likely you too) are all of the GPU DRM updates in the Linux 2.6.34 kernel that includes GPU hybrid switching, initial ATI Radeon HD 5000 series KMS support (a.k.a. "Evergreen"), controversial Nouveau changes, ATI Radeon KMS power management support, Intel Sandy Bridge support, and much more.Outside of the graphics fun in this kernel to be officially released next quarter is a new filesystem (Logfs), a hardware driver for Apple's Magic Mouse, virtualization improvements, and other updates particularly to the Linux drivers and architectures.The Linux 2.6.34-rc1 kernel release announcement can be read at LKML.org...

    I have:
    Code:
    state: PM_STATE_MINIMUM
    What does it mean? The new kernel dropped about 20C (from 80C to 60C) which is already very good result but I still have a hairdryer instead of fan (it's sooooooo annoying). Maybe with ACTIVE instead of MINIMUM it'll be better? Is there any way to change it?

    Manufacturers do this already - isn't the issue that you want them to do it with *your* Linux distro rather than just with Windows ?

    The phoronix baseline test

    PHORONIX BASELINE TEST

    Have a series of test to check basic functionality.
    Suspend / Resume, Hibernate Same test really.<br>
    Acceleration<br>
    Sound<br>
    etc.<br>

    Manufacturers could begin testing before they release new hardware.

    hm, with this I have
    Code:
    state: PM_STATE_ACTIVE
    , but engine clock is always on default value...

    From the grub2 menu, I just added:

    Code:
    radeon.dynpm=1
    ... to the kernel parameter line. It works on both my HD4850 and my laptop's integrated 200M.

    Melcar: how did you enable PM ? I tried everything but I'm still on default clocks...

    I have integrated 3200 HD, may this be the problem? Is PM supposed to work with integrated cards?

    On my laptop (200M) it works a bit better, in that it's not unbearably slow. Thing is that when the core downclocks, response becomes "jumpy"; the mouse cursor seems to get "stuck" as I move it across the screen, and window animations sometimes leave a noticeable trace behind them. This again, is due to KMS making things slow and the slower frequencies only worsening the problem. Should be better once I move to a newer xserver.

    Mobility 3470 here. The first DRM power management patches did just that, slowing 2D to unacceptable levels. Since 2.6.33 + patches, it's become very good, with no noticeable slowness at all. Now, it seems to change core and memory frequencies very fast.

    And my notebook stopped hanging with a black screen due to overheating, as well.

    Now, I'm just hoping the current power management, or the future advancements, will be enough to cope with the summer's heat.

    Thank you developers.
