    I spoke too soon. Two out of three boots hung before lightdm appeared. Reverting to 3.2 kernel again.

    Re: Linux 3.4.0 rc7

    No joy here. My main system (i980x CPU, Intel DX58SO MB) hates both 3.4 kernels so far.

    Code:
    May 13 08:31:43 saturn kernel: [    7.740175] Installing knfsd (copyright (C) 1996 okir@monad.swb.de).

    and later...

    Code:

    and more...

    Code:
    May 13 08:33:08 saturn kernel: [   96.178270] BUG: soft lockup - CPU#3 stuck for 22s! [mount.nfs:1410]
    and the fun keeps coming...

    Code:
    May 13 08:33:42 saturn kernel: [  130.356610] INFO: rcu_sched self-detected stall on CPU { 0}  (t=15000 jiffies)
    May 13 08:33:42 saturn kernel: [  130.356613] sending NMI to all CPUs:
    May 13 08:33:42 saturn kernel: [  130.356660] NMI backtrace for cpu 0
    Oddly, it seems to work fine on another system with NFS shares. :\ So, I'm not sure of the real culprit yet.

    Re: Linux 3.4.0 rc7

    Quantal is moving along quickly. I'm up to kernel 3.4.0-1 on my Dell mini-10n (gma500):

    Code:
    frank@sweetie:~$ echo && echo -n "Date/Time: " && date && echo -n "Release: " && lsb_release -sd && echo -n "Kernel: " || cat /etc/*release && uname -s -r && echo -n "Unity: " && unity --version && echo && /usr/lib/nux/unity_support_test -p -f && echo || echo &&  dpkg -s mesa-utils && echo || echo && echo "Xserver xorg core:" && apt-cache policy xserver-xorg-core | grep Installed && echo

    Interestingly, Unity 2, but using:

    Code:
    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
    Even this early there's a way for limited systems to use Unity. Don't understand where VMware fits into the picture? VMware into the kernel but using LLVM as compiler instead of GCC?

    (Keep in mind I'm not a specialist and actually need to find the time to study more). As far as I could understand: LLVM is capable of creating architecture-optimized code in run-time (not from source code, but from an intermediary state object code). So while it will look like a standard module, from the kernel perspective, it is somewhat more dynamic in the way it will execute the calls.

    About VMware: Gallium3D was a project of Tungsten Graphics. VMware acquired Tungsten planning to turn Gallium3D into a solution for 3D acceleration in its Virtual Machines (VMs can't can't have hardware accelerated graphics*). Later it transferred it to the Mesa project, but apparently is still a contributor.

    So, we know software rendering of GL is not new: mesa can do it if you set dri to off in X config. But it can be done better and reach a superior performance with Gallium3D and llvmpipe. So the thing stops being interesting only in the Virtualization scenario and also becomes a viable alternative to render OpenGL in PCs with weak GPUs but reasonably powerful CPUs.

    (*) Except for Xen and (probably soon) KVM, which are not working on improved 3D graphics for VMs but instead on VGA PCI-Passthrough. Xen already did it and, in this case, the VGA performs very close to 100% in a virtualized environment (little overhead - it gets dedicated to the guest OS).

    If you want it to clear the screen faster, you can always turn it upside down and shake it . Drawing the screen never was easy...

    Massive packet loss, here...




    All other web sites are working fine.

    Maybe it's the "radiation orange" theme. LoL!
