how about the cpufreq modules? howto compile the cpufreq modules for the kernelone?
is it also possible to enable CONFIG_DEBUG_KERNEL for more detailed powertop infos?

Cpufreq is already compiled in-kernel, no need for modules

I've really thought on enabling CONFIG_DEBUG_KERNEL but I wasn't sure that it's *really* needed. I've strip down the kernel as much as I know and by doing so, leaved it behind.

What I can do is another build with it enabled so everyone can see if there's really no difference, we can switch it back on

Edit: New build with debug enabled

AFAIK you can pass any module parameter to the kernel's command line using something like this as an example:

Passing snd_hda_intel.model=acer as a kernel option fixes the sound issue when suspending/resuming.

Has anyone got any ideas on how the ath_pci should be set up, how does black/whitelisting modules work in Arch, anyway?

What does the overclocking (parts 4 and 5) sound like to you guys?

zzats, Seems interesting enough.
The I/O scheduler reflects the problems I'm having with firefox (still to use the FF tunning tips), although the usage of swap and ext3 in that tutorial is far from being the best approach.

Did you install the one with the CONFIG_DEBUG_KERNEL enabled, and notice any impact?

Link to the new kernel http://clientes.netvisao.pt/gtknight/ke … pkg.tar.gz
and the Kconfig used http://clientes.netvisao.pt/gtknight/Kconfig

I installed this version. The following problems occured:

- While booting, some errors from the Vesa FB appeared. Nevertheless the framebuffer worked fine. I use vga=789.
- The battery state info is no longer in /proc/acpi/battery. I use a script which reads this to inform me about the remaining capacity and this does not work now. I have no info about the remaining battery life.
- fuse does not work. Module not found. I think I will have to recompile it for the custom kernel, right?

The battery problem is crucial for me, so I switched back to the stock kernel.

I just looked into your Kconfig and I suspect that these values may have disabled it:

# CONFIG_ACPI_PROCFS is not set
# CONFIG_ACPI_PROCFS_POWER is not set
# CONFIG_ACPI_PROC_EVENT is not set

FUSE is compiled in-kernel, please remove the loading of the module, there's no need for it
ACPI files in /proc are deprecated you can have the same values from /sys/class/power_supply/BAT0/...
The VESA errors I've already known them, it's probably because they're trying to load after the intel framebuffer driver already been loaded, I need to check on them.

Today I'll recompile the kernel with deadline I/O scheduler support, sound drivers that are used that currently are compiled in modules will be passed to in-kernel and CONFIG_DEBUG_KERNEL enabled for powertop usage, I think that this is an important (debug?) tool.

Thanks for the info. If the Intel FB works, shouldn't it be possible to simply remove the Vesa FB from the kernel?

gothicknight · 2008-09-11 09:04:24

I'm already on it... I'll have the kernel uploaded in 30min

Please, test this with care, at first I got some panic attacks, still to figure what happened, although seems to work just fine now.
Got a reduction from 2.1s to 1.6 in udev passing sound modules to in-kernel and removing more stuff from the kernel.

Keep in mind that this kernel is severly reduced and only made for booting as fast as possible with Aspire One hardware.
If you have an external device (TV card for example) you won't have drivers for it as is, for that you must recompile the kernel to fit your needs.

thanks for this blazing fast kernel! (just tried the one from 1104 today)
most things for for me (xfce4-battery-plugin doesn't, due to /proc/acpi/power missing, but that'll be upgraded soon i hope).
one other problem is the webcam. i can't find v4l-config in arch (what package is it in??), i have /dev/video0 (as a link to /dev/v4l/video0), but neither mplayer nor luvcview show anything:

[nex@onex ~]$ luvcview
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
Unable to set format: 22.
Init v4L2 failed !! exit fatal

[nex@onex ~]$ luvcview -L
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
/dev/video0 does not support read i/o
{ pixelformat = 'YUYV', description = 'YUV 4:2:2 (YUYV)' }
{ discrete: width = 640, height = 480 }
Time interval between frame: 1/30, 1/15, 1/10,
{ discrete: width = 320, height = 240 }
Time interval between frame: 1/30, 1/15, 1/10,
{ discrete: width = 160, height = 120 }
Time interval between frame: 1/30, 1/15, 1/10,

Time interval between frame: 1/30, 1/15, 1/10,
{ discrete: width = 176, height = 144 }
Time interval between frame: 1/30, 1/15, 1/10,

"does not support read i/o"??
any suggestions?

So it seems to be a good idea to compile with procFS acpi files...

I didn't compile them because there's a bug report saying that if there's a /proc and a /sys battery info, it's possible to have gnome-power-manager think that there's 2 batteries.

Here's the answer: http://gentoo-wiki.com/HP_Pavilion_tx2000#Webcam

luvcview -d /dev/video0 -f yuv

ecraven · 2008-09-11 13:05:13

thanks, the webcam now works too!
i'd suggest leaving the procfs part in until the major DEs work without it.
another question, i have followed the wiki for the extra function keys (volume, brightness etc.), is there a way to get the OSD that linpus uses working? the nice images and "progress bars" when changing volume and brightness?
brightness works (though it seems to be hardwired, works in BIOS and everywhere), volume control does not ;(

thanks again!

gothicknight · 2008-09-11 14:42:54

Try this revision: http://clientes.netvisao.pt/gtknight/ke … pkg.tar.gz

I've only changed the ACPI /proc/acpi directory nothing else.

ecraven · 2008-09-11 21:33:32

works very well! thanks again!

it happens now and then when i reboot (been rebooting too often that the kernel hangs, caps lock blinks, and nothing is shown (quiet boot i believe). i am not sure how to get more information about this, and i'm not sure how to reproduce it ;(
another one, sound works well (with model=acer), but i can't get the microphone to work. should i set capture to mic or internal mic? does it even work with model=acer?

arch on the one rocks!

ecraven, please remove the quiet parameter from the kernel's grub line on boot (using the E key) to see where's the hang in the kernel. It shouldn't happen, although I've removed so much from the kernel that I may have broken something important :$

My mic works fine... even without model=acer. But be aware that HDA intel driver is in kernel if you want to pass the parameter to the driver it has to be done or by sysctrl or by kernel's grub line parameter.

model=auto has been reported to enable the mic, I use that and it works fine. But suspend needs model=acer. See the Ubuntu wiki.

For me the latest kernel does not work. The framebuffer does not work (empty screen, blinking caps lock). Disabling the FB shows a kernel panic, that the root fs cannot be mounted.

gothicknight · 2008-09-12 10:56:11

humm... So it has been confirmed that the latest Kconfig does create kernel panics.

I have a copy of a old config and this afternoon I'll recompile everything.

No, actually I didn't try that one, the option seems like a step backwards for me. I vote for a kernel without it, and I'd like to see the powertop-suggested optimizations listed from the people who tried it.

But I did have some trouble with ACPI and thermal monitoring, it's not a priority for me.

But for firefox optimizations, here's my acer one optimized firefox's prefs.js stripped from unneeded parts

The goal is to keep firefox running in the memory, without having to cache too much (see browser.cache.disk.enable) and have as minimal memory footprint as possible.

If you have upgraded the RAM, feel free to multiply the browser.cache.memory.capacity by at least two. config_trim_on_minimize might be the wrong setting in terms of browser stability, but I'm seriously looking for comments and additional optimizations, if anyone has them in mind.

Has anyone got the solution to the ath_pci and suspend issues?

I'm experiencing random freezes when using the hard drive. For example mkdir just took over 15 seconds to complete. I'm using even more stripped version of the gothicknight's kernel with noop scheduler. I probably should use another io scheduler or could it be something else?
