[KERNEL] 32a GBO kernel. More designed to ROM cookers [07/09/2009]

gboddina · Aug 21, 2009

Here come our custom 32A kernel

Updated, see changelog

Sorry for the delay, I was taking some sun

and some work

.

http://www.mediafire.com/?mjgm5gcgmya

README:

Code:

HTC Magic Sapphire PVT32A kernel build.

This kernel build is only for 32A (HTC branded) version of the HTC magic.

It's designed to run FAST. (much more than the stock kernel).
I made some improvement in the config, removed uneeded things (all of this debuging message, hooks, ... is not needed for everyday use,
and use precious CPU cycle for nothing :).

You can use this kernel in your current ROM but you need to known what you're doing. (Boot image and ramdisk knownledge are required).
If you don't have those skills, you can wait a ROM cooker to build a ROM with this kernel for you. (It's not a subliminal message :p).

Hope you'll enjoy it.

In this archive you'll find:

README		-> this file :)
CHANGELOG	-> Errr... oh yes, got it! It's the changelog!
boot-gbo-v4.img	-> An boot image. You can try to boot it but you'll be more lucky if you ask your ROM builder :).
zImage		-> for ROM builders. You can include it in your boot.img file
config.gz	-> The config used to compile the kernel.
wlan.ko		-> Wlan driver for the kernel in this archive.
modules/	-> Extra modules you can include in you ROM (or not). IPV6, ReiserFS, NTFS, Tun, ...
modules/ipv6.ko			-> IPv6 support
modules/xfrm6_mode_beet.ko	-> Needed by IPv6 support
modules/sit.ko			-> Needed by IPv6 support
modules/xfrm6_mode_transport.ko	-> Needed by IPv6 support
modules/xt_TCPMSS.ko		-> Needed by IPv6 support
modules/xfrm6_mode_tunnel.ko	-> IPv6 over IPv4 support
modules/tun.ko			-> TUN/TAP Interface support
modules/tunnel4.ko		-> IPv4 Tunnel support
modules/ipip.ko			-> Needed by TUN/TAP Interface support
modules/ip_gre.ko		-> IP GRE security support
modules/ntfs.ko			-> NTFS support
modules/reiserfs.ko		-> ReiserFS support
modules/as-iosched.ko		-> AS scheduler
modules/cfq-iosched.ko		-> CFQ scheduler



Current version: 2.6.27-6

Excellent job.

Any chance you wanna talk me through building a kernel!?

gboddina · Aug 21, 2009

I think someone need to make a goot tutorial about this! (getting sources, applying the patch, building kernel, builder wlan module...)

I'm not a fan of making documentation but if nobody do it, I will, because the knownledge must be shared

Well, even if you could do something quick and basic it would be awesome

a good resource here..

Works on JACxHEROski-v1.4 for 32A.
(it's a fast HERO rom btw)
Thanks a bunch! I have multi-touch now!

Instructions
For the strong hearted only!

Testing the boot.img: (gboddina's instruction from original thread)

adb push wlan.ko /system/lib/modules/wlan.ko
adb shell sync
[Shutdown device, adb rebooting can cause wifi to not work]
[Fastboot device]
fastboot boot boot-gbo.img

Flashing the boot.img:

[Normal Phone Mode]
adb push boot-gbo.img /sdcard
adb shell cat /dev/zero > /dev/mtd/mtd2
adb shell flash_image boot /sdcard/boot-gbo.img
[Reboot Phone]

It's a nice basic kernel. But just wondering, in the original thread, it's stated that LED is working. But my Rogers Magic still doesn't show red LED during charging. Any explanations?

k4r1m · Aug 21, 2009

Thanks, 2.6.29 with compcache and the common g1 kernel modules would be nice =]

briggs81 · Aug 21, 2009

Any dangers with trying to use this, or things to watch out for?

hotweiss · Aug 21, 2009

This boot.img does not work with the Rogers ROM for me

It gets stuck at the Rogers logo...

There is another bootimage with another ramdisk , it will work just gå back to the orginal thread from the first post here and look!

it works! ...., waiting for the tutorial

Does your kernel allow changing the CPU freq? The previous one you made would not allow the CPU frequency to be set (By apps, etc)

at314 · Aug 21, 2009

is it permission problem... you cant write the frequencies?!

k4r1m · Aug 21, 2009

Just grabbed setcpu and it seems to halt after the intial page so it just freezes up after hiting the "always allow" page from the superuser app just after hiting "android cupcake 1.5" from the intial page of the app it self... what im trying to say that i dont think its a permission problem...

L10nH34Rt · Aug 21, 2009

So I just unpack boot-gbo.img and put the kernel in any rom?

at314 · Aug 21, 2009

/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

i cant find anything beyond cpu0.

Since this is active:

Code:

CONFIG_MSM_CPU_FREQ_SCREEN=y
CONFIG_MSM_CPU_FREQ_SCREEN_OFF=245760
CONFIG_MSM_CPU_FREQ_SCREEN_ON=528000

Manual cpu scaling cannot be done.

Seems that many people doesn't like this behavior. I am currently reviewing the config to made some performance improvement and will release 2.6.27-gbo-3 during this day.

Small poll so:
CONFIG_MSM_CPU_FREQ_SCREEN or CONFIG_MSM_CPU_FREQ ?

Well, I definitely like to set my CPU and this is pretty common in the stock kernels and other 32B kernels, so I would stick with this. Of course, this is -your- kernel, so you can do it exactly how you want to. :3

gboddina · Aug 21, 2009

It's not "mine"

. It's your kernel and my build

Better, it's a community kernel

I'll revert back to stock configuration for this part

.

Hey i don't wanna sound annoying lol since i already said this but any chance of compcache, squashfs, and cgroup? i'm pretty sure non of them are on the current build since there is lines in the ramdisk im using that try to use these features but it's failing and ofcourse just by looking at "mount"....

thanks for the hard work,
