Slicing and dicing the HD in a different way - NTFS, Fat32 and ZFS on B110

Hi All,

 So I thought I would  try something differnet on the AA1 10 inch, Fuse is pretty good for read and writting ntfs but it does seem to kill the netbook sometimes.

 With this new netbook I've sliced the disk this way:

40Gb - NTFS - Windows XP Home, still have to run iTunes

60Gb - Fat32 data

40Gb - ZFS - OpenSolaris Nevada (SXCE) B110

 I'm trying to setup everything so the data for my user is on the Fat32 partition even if it is Windows or OpenSolaris I'm booted into.

I can mount the Fat32 partition in OpenSolaris and I've link my user home directory to it.

So I'm building compiz 0.8.0, see if I can get the MSI to run it.

Found another bug in gnome-system-monitor, on my big Asus C90S powertop says:

 Cn            Avg    residency    P-states (frequencies)
C0 (cpu    running)        (8.4%)     1596 Mhz    100.0%
C1            3.9ms     (91.6%)     2394 Mhz    0.0%  

Wakeups-from-idle per second: 237.7     interval: 5.5s
Power usage (ACPI estimate): 0.000W

Top causes for wakeups:
67.6% (160.7)               <kernel> :    genunix`cv_wakeup
42.1% (    99.9)               <kernel> :    genunix`clock
21.4% (    50.8)                  sched :    <cross calls>
 6.5% (    15.4)               <kernel> :    uhci`uhci_handle_root_hub_status_change
 4.2% (     9.9)               <kernel> :    ata`ghd_timeout
 2.4% (     5.7)         <interrupt> :    ehci#0
 2.2% (     5.1)         <interrupt> :    ata#0
 1.9% (     4.4)               <kernel> :    uhci`uhci_cmd_timeout_hdlr
 1.7% (     4.0)               <kernel> :    genunix`schedpaging
 1.6% (     3.9)               <kernel> :    ehci`ehci_handle_root_hub_status_change


But gnome-system-monitor only shows one processor ?

So much to test, so little time :-)

How long did it take to boot SXCE 110?

Compared to what Wayne ?

It comes up faster than before maybe 45 seconds, shutdown or reboot is taking about 20 seconds.

Resume from suspend is about 10 - 15 seconds.

It's compiz and suspend / resume that's driving m crazy :-)

The output from powertop just indicates in what C-state the CPU(s) are in, not how many there are.

It's a bit strange that the C1 state has higher frequency though... On my linux-box I get this:

Cn Avg residency P-states (frequencies)
C0 (cpu running) (51.2%) 2.01 Ghz 3.5%
C0 0.0ms ( 0.0%) 2.00 Ghz 0.1%
C1 mwait 0.0ms ( 0.0%) 1.60 Ghz 0.2%
C2 mwait 0.0ms (40.6%) 1200 Mhz 0.5%
C4 mwait 0.2ms ( 8.2%) 800 Mhz 95.7%

It has a Core2 duo cpu.

When will osol get support for lower C-states and tickless kernel?

Hi, I believe it's in B110

Nice,

that will make it a more viable alternative for laptops. Now only real synaptics drivers are missing ( I really want scrolling to work ) for osol to have a partion on my hdd. Oh, and mplayer and friends of course ;)

Turns out that lower C-states are only initially available on Nehalem class of cpus, which not many laptops have...

And a powertop output shows that there are still some work to be done in the tickless department:

Wakeups-from-idle per second: 621.3 interval: 5.0s
Power usage (ACPI estimate): 25.618W (discharging: 0.8 hours)

Top causes for wakeups:
26.7% (166.0) <kernel> : genunix`cv_wakeup
16.1% (100.0) <kernel> : genunix`clock
10.1% ( 63.0) sched : <cross calls>
7.0% ( 43.5) <interrupt> : i8042#0

The genunix`clock seems a bit to regular to be tickless.
