    I wonder where Michael looked for PowerTOP git...
    probably in the wrong place ;-)

    while Auke has been on baby leave for 2 months, we've done quite a few things before then and for example MeeGo...

    fixed already

    The regression got introduced in git commit a7cf4145bb86aaf85d4d4d29a69b50b688e2e49d on May 21st, and has the effect of causing udev to go into an infinite loop consuming tons of CPU. This was...

    Getting more statistically correct is always a good thing of course.
    My personal experience is that PTS runs most tests at least three to five times and THEN looks at std dev. Also, from using some...

    really.. it's the power button.

    hit the power button, and you'll get a popup dialog like usual.
    Our UI designers feel that since the device has a real button for this, adding a software button...

    there is thing on your computer called "power button", it's the same button you use to turn the machine on....... try it ;-)
  6. Moblin wasn't "based on" Fedora (in the sense...

    Moblin wasn't "based on" Fedora (in the sense that Ubuntu is based on Debian), it borrowed some packages from Fedora, others from OpenSUSE etc.

    Adding Fedora repos to either Moblin or MeeGo is a...

    So in MeeGo 1.0 we've worked quite a bit on performance and power optimizations (and it seems it pays off ...):
    * We are using a gcc with Atom optimizations (backport from gcc 4.5 basically)
    *...
  8. Suggestion for a benchmark article....

    Window managers, and especially compositors, have a real impact on graphics performance... I wonder if Michael is up for doing a Phoronix Benchmark suite run for various WM/compositors...

    another thing to look at is the value in
    /sys/block/sda/queue/max_sectors_kb

    lower values hurt throughput a bit, but increase interactivity a lot.

    64Kb is often a sweetspot
  10. yeah I missed it ;) thanks looks like there...

    yeah I missed it ;) thanks

    looks like there are 2 things going on;
    the VM is really busy, as well as the disk writeback threads. Based on the SVG it looks like the VM indeed swaps some stuff out...

    the png is not very detailed (yay zoomable svg) but it is really looking like you have the VM system working hard, and various things then...
  12. BFS being better than the kernel is currently an...

    BFS being better than the kernel is currently an assumption more than a hard fact.
    BFS did show that the scheduler in 2.6.30 and early had issues, great, but 2.6.33 has a vastly improved...

    if you can get timechart set up (part of the perf program), you can do

    perf timechart record sleep 10
    perf timechart

    the first command will do a 10 second recording of the activity in your...

    That's likely neither the process scheduler or the disk scheduler, but the VM subsystem.... it threw out the code pages for the mouse X code.. and now it needs to be read back from disk.
  15. 10.000Hz ? HZ is no longer really user visible

    Until a few kernels ago, HZ was very user visible, because the select() and poll() system calls rounded internally to HZ values. That was the one place where HZ was really visible, esp HZ=100 and to...

    isolinux cannot reliably (isolinux is the cd booting part of syslinux, and this is an artifact of how "magic" cd booting is), but extlinux (the harddisk boot edition) can boot windows and anything...
  17. grub2 vs syslinux

    Interesting to see what various distributions will pick in the next year or so; grub2 or syslinux.

    Well, they already use syslinux for all their CD and live images, just wonder if they will extend...
  18. bit misguided

    Disabling C states? Why? The kernel has a perfectly fine API to control the latency via a file in /dev, and with that you only disable the C states that are needed, and only for the duration you care...
  19. what IEGD is

    IEGD is a driver set made by the Embedded group in Intel for various Intel embedded boards and platforms (including boards designed for in-car use, eg IVI); one of the key things is long (7 years or...
  20. what IVI is

    IVI stands for "In Vehicle Infotainment"; so "stuff for in cars" in english.
    The Moblin IVI builds and releases aren't for netbooks, but for in-car computers.

    Car manufacturers normally put their...
