[Project] kernel-netbook

cylverbak · 2010-12-20 16:40:04

My Bluetooth toggle (eee-control) is not surviving a re-boot if it's turned off at the time of re-booting.
I can't write into /sys/. (ie. echo 1 > /sys/devices/platform/eeepc/bt) as there is no bt file to change from 0 to 1.
Somewhere I read that /sys/ is a virtual folder set up by the kernel? I'm using the latest netbook-kernel.
Any hints on where to look to fix this before I re-install?

Thank you and have a very Merry Christmas!

When i use eee-control i get a lot of errors...His develop has stopped, and i'm recently switched to acpi-eeepc-generic and all works fine! I suggest you to give it a try

p.s. the right name is /sys/device/platform/eeepc/rfkill/rfkill1/state

cylverbak · 2010-12-20 20:29:36

Thank you again dieghen89. You've got eee-control in your signature so I'd thought you were using it with no problems. I'll switch to acpi-eeepc-generic and see how it goes . . .

The 2.6.36.2-5 version fixes all problems (shutdown kernel panic and suspension)

cylverbak · 2010-12-21 19:39:43

Ok, I'm using acpi-eeepc-generic 1.0rc3-0.1 with 2.6.36.2-5 and am having the same problem.

If I turn off bluetooth (mouse) with Fn-F7 and forget to turn it on again before shutting down or re-booting, I can't turn bluetooth on again with Fn-F7 - I have to either make sure I've pressed Fn-F7 once again so it says "bluetooth on" and re-boot or just re-boot and turn it on in BIOS. I'm reasonably sure it used to work so I'm guessing I've mucked something up that's interfering.

I'll try a re-install after the holidays.

cylverbak · 2010-12-22 13:52:48

Solved! I fouled up when configuring acpi-eeepc-generic.

dieghen89 · 2010-12-26 11:32:23

Guys, now for 2 weeks i'll work and i'll have no internet connection, so i can't update if a new versions will be released...Luckily this version seems have no problems...

admiralspark · 2011-01-10 06:13:55

I just wanted to drop in and say thank you for building this! My tiny Atom-powered netbook is booting in 14 seconds (half of what my i7 Lenovo takes on Linux Mint) and all hardware works right away!

EDIT: I was wondering, could you build the kernel with CONFIG_INOTIFY enabled for powerTOP usage? It's needed so that powerTOP can detect more devices etc. that are using up battery life...really useful to the netbook users! I'd be more than happy to do it myself if you'd like, but this is your project..

I've heard the acpi-cpufreq driver doesn't support the Atom N450 at a frequency under 1000MHz - is this true and does this kernel patch get the frequency down to 800MHz as it is in Windows?

philacorns · 2011-01-16 07:41:41

Can I use it on my core2 laptop changing CONFIG_MATOM to CONFIG_MCORE2?

dieghen89 · 2011-01-16 16:06:51

@admiralspark

diego@eeepc ~>sudo zcat /proc/config.gz | grep CONFIG_INOTIFY
Password:
CONFIG_INOTIFY_USER=y

it is already enabled, powertop says wrong things

@tjbp
mmh i've already tried to reduce the timer, but then a lot of problems appeared...Btw I'll give it a look...

@philacorns
i think yes, but you have to look if all modules that you need are enabled...This kernel is moulded on netbooks hardware...

admiralspark · 2011-01-31 21:17:28

Aye, I found that out when I was looking at the config on the AUR. It's still working faster than the mainline kernels, and if you'd like any help with the project I'd be more than happy to run tests/compile/tweak etc.

@philacorns: This kernel has netbook modules compiled into it, and little else. However, you can build your own kernel if you know what modules you need--and there are many good guides on the internet to guide you through it!

@tjbp: I have an N4xx and it doesn't go below 1GHz on this kernel (or the mainline, I believe, though I haven't tested on the newest update).

Thanks for the heads up.

admiralspark · 2011-02-01 19:50:18

One thing I want to point out for those upgrading to the newest version: kernel 2.6.37 broke support for software using the deprecated /proc/acpi reports for temperature etc. Expect new updates to fix it, but the current version of acpi will not report the temperature from the same place as previous versions, so things like conky and temperature monitors for gnome and lxde will report 0*.

To fix in conky: replace

$acpitemp

with

${hwmon 0 temp 1}

dieghen89 · 2011-02-04 12:47:28

Ok thank you admiralspark, if i need help i'll ask you

About the sensors, i don't know...I use KDE and the temp plasmoid works as before...In this days (untill the second half of march) i'm a lot busy (uni and work) and i haven't a lot of time to deepen the question...If you have some news i am very inclined to change something

p.s. i'm thinking to add Tux On Ice patch for the hibernation, somebody is against of the idea?

p.s.#2 with the next release i'll put BFQ as optional, i haven't notices any changes, only an higher usage of the cpu...

p.s.#3 i've just bought a 1015pem and sold the old 1005HAH

Congrats to your 1015pem its a great device, I own a very similar 1015pn.

Could you set CONFIG_NR_CPUS to 4 since the current Atom processors do have two physical cores + hyperthreading
Furthermore I noticed that Linux only scales down the processors to 1000mhz (Win7 around 700mhz) but I haven't looked more into this yet.

dieghen89 · 2011-02-06 17:17:46

Thank you raph! In my testing release i have already enabled the 4 cpu with the 2.6.37.1 i'll update the config in google code and aur

About the frequency, i don't know...The atom n550 has only 1000MHz or 1500MHz, no middle way....If you have some news please tell me

Zom · 2011-02-08 08:16:32

I'd agree with just dropping BFQ altogether. Thing has caused me really unreliable performance. Then again, I'm on the A110L model of the aspire ones, so I just thought I was a special case.

But yeah, CFQ is good enough on regular harddrives, and apparently noop (which I'm currently using) is better for SSDs.

Personally, I never hibernate my netbook, just suspend it, so I don't care either way for tux-on-ice. I don't see any harm in including it though.

cylverbak · 2011-03-05 02:56:09

I'd like to ask a really dumb question . . .
What do I put in /etc/rc.conf to start acpi-eeepc-generic? I can't seem to get it working. This is on a re-install. I did have it working just fine first time around but that was months ago. I have no idea what I'm missing this time around. EeePC 1000.
Thanks folks.

Edit: (Solved) 1 letter, 1 lousy letter . . . I'd been using acpi instead of acpid. Thank you for having that info dieghen89. Just posting here reminded me of your website. And google translate did an awesome job of explaining it to me in english Gads the internet is wonderful!

Just tried to switch to kernel-netbook. Installation works fine but I can't get broadcom-wl to compile. It stops at asm/io.h and complayins about that the xen.h is missing.
Is it even necessary to install the broadcom-wl module with this kernel? Or should I remove the old wl package that was compiled for the standard kernel first?
I hope this Question is not to stupid but I don't know where to look next.

Zom · 2011-03-10 12:49:58

Personally, I don't use broadcom-wl. While I did, my computer just froze randomly.

But why not just use the precompiled kernel on the google-code page?

Manji · 2011-03-10 13:24:29

I'll give that a try today. But there shouldn't be any differences between the yaourt build kernel and the pre build kernel.

Edit:
Got it. The wl module is already shipped with the kernel. I just removed the old aur broadcom-wl module and it loaded the module properly.
Now I have to get wlan working with the wl driver.. still no scanning possible.....

Well, true, except you don't have to spend time building the package on your netbook with no real benefits.

For the wl module, make sure you put wl in your MODULES section in rc.conf, and add !b43 to disable the other driver.

Manji · 2011-03-10 19:07:46

I've done this already. Just as described on the wiki page. I also disabled ssb and b43legacy.
I just don't know what do do now. Is it a kernel related problem (tried the same on standard kernel: same thing) or is it a driver problem?
There are no Bugs regarding to this kind of problem so I seem to be the only one having this problem.

Strange.

What netbook are you using by the way?

Arch Linux
