[KERNEL][Mini/MiniPro/Active/LwW] Rage Kernel v2.7 / v2.8 / v2.9 for FXP CM7.2.0 ROM - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

This is Rage Kernel v2.9 for Xperia Mini / Mini Pro / Active / Live recompiled to run on FXP CM7.2.0 ROM from Freexperia Project here.
The boot image consists of kernel compiled from DuMOHsmol's Rage Kernel v2.9 source, FXP wi-fi driver and FXP ramdisk. It is tested running in FXP122 CM7.
The kernel is compiled using FXP default config, modified to enabled added features in Rage Kernel, so overall the features is similar to Rage Kernel v2.9 (see post #2 below)
Credits:
Many thanks to DuMOHsmol for Rage kernel source and DoomLord for providing the base/stock source.
Thanks for Freexperia Team for making such a great rom.
Thanks for wucinac, HUdasp, gandhar, Snoopo, & jakobxxl for initial testing and feedbacks.
This kernel will not be updated everyweek like FXP rom releases. It would only be updated if there's update in Rage Kernel or there's update in FXP ramdisk/ROM that requires changes in this kernel too.
I mainly compiled this kernel because it gives good battery life, so I haven't tested all features that Rage Kernel offer. Therefore I can't really confirm that those added features will work fine in CM7. What does work is the basic functionalities (like calls, wifi, bluetooth, camera, etc) and added cpu governors, overclocking options, and added i/o schedulers. What I haven't test: zram and swap.
And because I personally considered this kernel as some kind of a workaround for the battery drain issue in fxp kernel (see post #3 below), then if FXP team has fixed it, this kernel might be no longer needed.
As of version 2.6, changes from original Rage Kernel source are below:
4 files in Rage source replaced with files from FXP source :
- arch/arm/mach-msm/board-semc_mogami.c
- arch/arm/mach-msm/sdio_ctl.c
- drivers/mfd/marimba-codec.c
- drivers/misc/lm356x.c
Files sdio_ctl.c and marimba-codec.c is replaced to avoid compiling errors when using fxp defconfig. The file board-semc_mogami.c is replaced to fix touchscreen problem when using original file. File lm36x.c is replaced to fix force close problem in Torch app.
Another change is patch from here applied to fix the touchscreen issue.
Changes in version 2.7 are included as a patch files in the download post below.
Changes in version 2.8 & 2.9 are related only to cpufreq driver & cpu governors, so the patch from 2.7 can still be used, but the cpufreq part of the diff must be removed.
Version 2.7 / 2.8 / 2.9:
Please see all download links for Mini/Mini Pro/Active/LiveWithWalkman in this #75 post.
Flashing disclaimer applies! Use this kernel at your own risk.
How to use:
1. For the first time CM7 users: Flash the Freexperia CM7 kernel & Rom first, and make sure everything works fine, and then continue to step 2. For those that already have CM7 running, just begin at step 2.
2. Flash this kernel using fastboot.
3. Reboot to CWM and wipe cache
4. Reboot again.
Notes :
- This kernel is not supported in anyway by FXP team or original Rage maintainer DuMOHsmol. Anyone having problem, please don't ask them for support. Just ask in this thread & I'll try to figure it out.
- Battery life is not solely affected by the kernel. It can also be affected by apps/mods/tweaks used or applied in the rom. If battery drain is high, then please check what cause the wakelocks using apps like BetterBatteryStats here
- There are instances that using Google Maps or Latitude (or maybe other gps-related apps) would cause GpsLocationProvider keeping the phone awake, like the case in this post #82 and post #34. This situation can be diagnosed using that BetterBatteryStats app mentioned above. The workaround is to disable gps and reboot the phone.
- Of course, other than advantages, there are also disadvantages using this kernel in FXP cm7. Advantages including: a bit better battery life, more cpu governors, more i/o schedulers, etc. Disadvantages: I perceive sdcard i/o is somewhat slower, sometimes there's lag in video recorder, there might be broken features in future FXP releases, not supported by FXP team, and there might be other problems that haven't been encountered yet. If anyone experiencing more disadvantages than advantages using this kernel, then please consider using FXP kernel instead.

Features (quoted directly from DuMOHsmol's Rage Kernel original post here ) :
DuMOHsmol said:
This is my kernel, it's based on stock SE 4.0.2.A.0.74 kernel sources, with some things from DoomKernel by DooMLoRD (so go and say thanks to him, and other developers too).
It has:
- Overclock up to 2Ghz
- CWM Recovery 5.0.2.7
- Prerooting
- CPU Governors:
brazilianwax
smoothass
smartassV2
SavagedZen
interactiveX
lagfree
minmax
Scary
smartass
interactive
conservative
userspace
powersave
ondemand
perfomance
v2 added:
- Xperia Mini support
- Tun/tap interface enabled (VPN, ipv6)
- Swap support enabled
- Two way call recording support added
- I/O schedulers:
noop
anticipatory
deadline
cfq
bfq
vr
sio
v2.1 changed:
- disabled NFS and CIFS (battery drain fix from DoomKernel), let's see if it can really increase battery life.
v2.2 changed:
- moved to from 4.0.2.A.0.58 to 62 source, though I didn't see any changes
- added 0% battery workaround patch by Bazoocaze. I don't even know what it does but it seems to be something useful since everyone includes this in their kernels
- New cpufreq driver from DoomKernel. You can experience some problems with overclocking now (my phone becomes unstable at 1.8GHz now, instead of 2.0), but phone eats much less battery in sleep. I've also changed 1018Hz to 1024Hz and 249Hz to 245Hz because those new numbers looked wierd
v2.3 changed:
- moved back to 4.0.2.A.0.58 source (just to make sure that everything will work).
- updated version number in ramdisks to 62.
- removed 0% battery workaround patch (it's useless on our devices).
- reverted old cpufreq driver with small fix. It should be stable now and phone seems to eat less battery than in 2.1. (thanks himasura for lots of testing)
- salvaged some ram.
- enabled NTFS support.
- enabled usb-storage driver, so you don't need to manually load usb-storage.ko now.
- Version number now shows version of kernel (#23=2.3).
v2.4 changed:
- Now phone lights up blue led to show when you can enter recovery (thx to DooMLoRD).
- Minor changes in ramdisks.
- Enabled hid drivers for microsoft and a4tech.
v2.5 changed:
- Re-added CIFS
- Enabled ext4 support
- Added zram and cleancache drivers
- Added lulzactive governor
- Root fs now mounts as rw after boot.
v2.6 changed:
- removed lulzactive governor as it wasn't working properly (thx to kamarush and others for pointing that)
v2.7 changed:
- moved to sony 4.0.2.A.0.74 kernel sources (updated touchscreen driver)
- Increased GPU dedicated memory to 4MB
- Updated su binary in autoroot.
v2.8 changed:
- added new cpufreq driver at last (with CPU frequency fixup by DooMLoRD), battery drain is lower now. I left version 2.7 too for those who want higher overclock or have some problems with 2.8.
Everything else is similar to stock kernel for now.

A bit background:
I use FXP CM7 rom for my mini pro since release 049 and like it very much. One thing that made me keep switching back to stock rom was the high battery drain, because in my daily activities electric plug is not always readily available, so battery life is critical for me.
In fxp 052 I got a bit desperate and trying to use custom kernel based on stock from bbooff here, with fxp rom. The battery life is excellent, just like stock rom, but I encountered 2 problems: touchscreen sometimes become unresponsive and wifi was not working (even if I replaced wifi modules with stock).
Finally, I decide to learn how to compile android kernel, and I found that it is quite similar with compiling linux kernel, which I've frequently done to my computer and laptop.
So, I compiled kernels from 3 sources and compare the battery life in my mini pro. They are from DoomLord's official SE source, DuMOHsmol's Rage kernel source, and krizky82's X Kernel source. I also recompiled kernel from FXP kernel source using stock semc_mango_defconfig, to see if battery life is better. The conclusion is that best battery life is achieved using stock and Rage Kernel, and I've been using FXP with rage kernel since release 102 and haven't considered going back to stock rom again.
I posted in Rage Kernel thread to thank DuMOHsmol, and since then there's 3 xda members that ask me to share this kernel, so I make this thread.
I hope this could help those who want to use FXP CM7 and need a battery life that's close to what stock rom offer.
Note:
As of release 114/115, FXP kernel also has better power management and quite a good battery life. The power consumption difference between this rage kernel and fxp kernel is not as much as it used to be before. In case of broken features or any problem caused by using this kernel in FXP cm7 rom, then please consider using FXP kernel instead.

Okay, I'll check it. I might zip the wrong file. What is your device? I assume it is mini / st15? Because kernel for mini pro works fine in my mango. I'll check and if needed I will re-compile it.
Edit:
I think the problem was I incidentally used wrong ramdisk for mini kernel.
I have made a new kernel for mini, but it needs testing first. So, if anyone's willing to test it, please send me a PM. Thank you...
Edit:
Fixed. Link for mini updated.

Thank you!!
Im using cyanogen fxp 111
Only need flash the kernel?
Or need make a full wipe?

You are using mini pro, right? I'm still fixing kernel for mini.
You don't need to do a full wipe, just wipe the cache partition.

Yes im using the mini pro
Thanks!

---

thanks a lot.even i was switching back to stock because of the battery drain ..will try this on my mini pro today

---

i am using fxp111 on my st15i,thank you for your great work .

hi ,greenAlgae ,i am sorry to tell that i encountered the same problems with using your fixed kernel ,it may not the ramdisk,but the drivers,i think .
by the way ,some of us using the rage kernel have encountered the same problem,they aslo "complained" the boot-loop ,so i think the problem is kernel itself not the the ramdisk ,i am very happy if you will fix it ,thank you much .respected your work

Is there any error when you flash it using fastboot? Did you get to boot logo only or you get to cyanogen boot animation when the phone bootloop?

Thank you wucinac. It seems there's some kind of inconsistencies here. Hopefully it can be worked out, else i would have to pull out the kernel for mini altogether.

For st15i i have to use fastboot query with flag:
Code:
fastboot -i 0xfce flash boot boot.img
fastboot -i 0xfce reboot
P.S. Rage flash'ed without any problems. Kudos to developer, many thanks for merging battery save and direct call record!

---

oh great! Let's test!

So, it does work for mini after all, right?
All credits goes to original devs. It was DuMOHsmol who added the features, so your kudos goes to him

So long time ago i using stock rom, and rage kernel are the best, i think that are the best kernel
For stock neves restart the phone on overclock , i dont back to stock rom never thanks!!
Sorry for my bad inglish

Well, overclocking is the feature that I very rarely use. Because I use this kernel for better battery life, and overclocking might just negated that
But I'm glad that it works for you

I have installed your kernel on my sk17i .. with FXP 111, but overclocking is set to 1024?
