[Project] kernel-netbook

Meyithi · 2010-04-04 21:53:22

Looking @ april screenshot thread seems there are lots of Arch users with netbooks, myself included

This project is extremely relevant to my interests! Many thanks!

Curious why you have reverted back to x86_32 only ?

dieghen89 · 2010-04-05 11:37:30

Because the broadcom-wl driver are different 32 and 64...So I should compile it for both arch and now I haven't time....I've 2 choice, or modify the pkgbuild allowing the 64 bit edition -not tested!- and put in google code only the 32bit precompiled package, or ask someone if would come in the project as 64bit maintainer (someone with a pine-trail, so he can do also some test)....

Today I leave home for 11 days, and I'll be w/o internet connection...so I'll read all your replies when I'm back...

I currently use 2.6.34-rc3 and wonder how much you'd benefit from this kernel.
When I saw an Ubuntu user trying a netbook optimized kernel vs the stock kernel I was amazed about the HUGE speedup it gave in boot time. How big is the improvement here?

Also "Light, the package size is about 4,5 MB" makes me wonder if there are all drivers as modules included. I don't want to end up connecting a USB device and not having the appropriate driver.

barzam · 2010-04-08 11:05:09

2.6.33-2 compiled just fine, I have had no issues whatsoever using this kernel. Just edit the kernel config to your liking if something is missing.

Btw, nice to see the Arch logo return, although Tux in 2.26-33-1 was fun.

The muting issue reported above is still present. No big deal, and I haven't bothered to try resolving it yet.

Hey, just to let you know that the module you added fixed the right-hand card reader as expected.
"sudo modprobe pciehp" works now.

I can't mount my LUKS encrypted partition:
Kernel panic - not syncing VFS: Unable to mount root fs on unknown-block(0,0)

My grub2 linux line:
linux /vmlinuz-netbook cryptdevice=/dev/sda3:root root=/dev/mapper/root resume=/dev/mapper/swap acpi_osi=Linux noapic ro

I suppose I need the initrd to decrypt the goddamn luks partition?

pielgrzym · 2010-04-15 18:54:28

I guess some of the important stuff is still a module:

CONFIG_CRYPTO_MANAGER=y
CONFIG_CRYPTO_CRYPTD=y
CONFIG_CRYPTO_CBC=y
CONFIG_CRYPTO_SHA256=y
CONFIG_CRYPTO_AES=y

Just made those tweaks and I'm recompiling again I'll report if it helped

pielgrzym · 2010-04-15 20:21:03

Still kernel panic.

pielgrzym · 2010-04-16 08:11:55

Compiling nvidia sata module inside kernel does not help either. Any ideas what could produce such error?

pielgrzym · 2010-04-16 08:59:28

I'm totally out of ideas. Perhaps someone will see what I miss in my config the netbook is asus eeepc 1201nl
here is the config: http://pliki.kmicica.net/kconfig-netbook
here is the lsmod (on a working kernel): http://pliki.kmicica.net/lsmod
here is lspci: http://pliki.kmicica.net/lspci

pielgrzym · 2010-04-16 09:08:09

Someone just told me the device-mapper needs to operate in userspace, so I can't decrypt the root partition without intrd

dieghen89 · 2010-04-18 11:45:10

Here me back!

@pielgrzym
yes for the encrypted partition the initrd image is needed...With other guys in italian forum we can't use that partition with this kernel....

The only solution is to recompile the kernel with initd support but in this case I don't know how many benefits you can gain compared with the stock one...

bandito · 2010-04-18 12:14:21

Just installed the kernel-netbook on Samsung N110 and it works perfectly. Even speakers get muted when I plug in the headphones, so far so good, love the package and your contribution, keep up the good work.

Best regards,

bandito

If only it was patched not to wait for each encrypted device 10 seconds (the stock waits 10 sec for MMC card with the key, 10 sec. for root and 10 sec for swap - this makes 30s extra waiting before the actual boot begins) than it would benefit a lot!

Thanks for the reply

dieghen89 · 2010-04-22 09:11:59

@bandido
thank you for the feedback!

@pielgrzym
You can try to use my config and enable the initrd image, than add the modules for the encrypted partition and you should solve so....

knedlyk · 2010-04-25 21:31:07

What netbook models this kernel support? Does it support Samsung n120 hardware?
I think it would be good to post the list of supported/tested netbooks somewhere...

dieghen89 · 2010-04-25 21:35:28

In google code there is a list of the supported models...

All n-series should be supported....

knedlyk · 2010-04-25 22:03:03

Oh, I see. One more question: Do I need to make some specific changes in config file? Can I just exit from menuconfig and pray that my n120 sammy be able to boot?

dieghen89 · 2010-04-25 22:07:09

You can found some precompiled package in the Download section always in google code (is written here in the first post)

p.s. in google code in the wiki there are also an install guide...

Is there a specific reason you removed JFS support? I think it's a pretty good filesystem for netbooks because it's low on resources.

Also this kernel doesn't support rtl8192e wireless chip that I have in my Samsung N310.

Thank you for the report Aakko...With the next release I'll include that modules!

You are the first that needs JFS

dieghen89 · 2010-05-31 18:36:17

I've just updated the package both AUR and google code!

2.6.34-2 add JFS and rtl8192e support, and fixes the rt2860 problem (firmware missed)

katafrakt · 2010-06-08 08:58:35

I tried this kernel yesterday/today, looks great but it lacks my rtl8187se wifi card support (r8187se module) in binary version downloaded from google code. I think if you like to support MSI Wind you should add this

dieghen89 · 2010-06-08 09:06:01

With 2.6.34.1 i'll add that module

Arch Linux
