[KERNEL][OC/UV][BFQ][AUFS][FTW][GPL] HCDR.Kernel v4.2 || Flash to any ROM

Announcement:
I am pleased to announce that from now on I will be working with ralle.gade too! He is a kernel dev with a lot more experience than me who can hopefully bring us some really cool stuff
Hey guys,
I've made this thread to share with you my kernel for the Wildfire. It is based on HTC's own kernel, however I have added patches specific to FroYo (to enable sd-ext support, stop screen flicker, enable touchscreen). It also features overclock to 768MHz. The kernel was built for the CM ROMs which I am working on.
You can get the source here. To build it, navigate to the source directory and run the following command:
Code:
make arch=ARM subarch=ARM cyanogen_wildfire_defconfig
You can then run
Code:
make arch=ARM subarch=ARM
to compile the kernel.
You will get a zImage which you can then add to a boot.img for a ROM, as well as a bcm4329.ko WiFi module to be added to /system/lib/modules
I recommend that only developers try this (for now anyway) and the rest of you wait for the devs to release an OC kernel for their ROM.
I have attached a prebuilt zImage (kernel) and wifi module in a zip folder. DO NOT TRY TO FLASH THIS. It is not a flashable zip, but the resources necessary for devs to make a patch of this for their ROM.
The v4 zip attached below can be flashed to ANY ROM without any negative consequences. For devs, the zImage and WLAN module can be found inside if you wish to use it as standard kernel in your ROM.
Changelog - v2:
*Added Ext4 support
Changelog - v3:
*Added BFQ Scheduler (by ralle.gade)
*Added undervolt (by ralle.gade)
*Other patches by ralle.gade (more details can be found in source)
*ralle.gade took yo' 19MHz
Changelog - v4:
*Added AUFS overlay (by ralle.gade) - adb shell or terminal emulator "aufs --enable" to activate system r/w
*Added interactive CPU scheduler. (by ralle.gade)
*ralle.gade gave back yo' 19MHz
*Added newer Wireless driver (with Wireless-N support) (by me)
*Hidden easter egg (unintentionally added by me) - Only works if your ROM has the necessary files (I'm looking at you, adeadrat )
Changelog - v4.1:
*Set default freq. to 245-518 MHz - Should fix booting problems for some people
Changelog - v4.2:
*Update WiFi driver to fix WiFi sleep bug (by zinx)
Known bugs:
*No WiFi on some roms. If it doesn't work on 4.2, use 4.1
If you'd like to donate, use the link in my signature or above my avatar. You can also donate to ralle.gade here. It would be much appreciated
Thanks to:
*adeadrat - for informing me that the OC actually works
*HTC - for releasing their kernel source
*Google & The Android Team - for developing android and making it open source
*Linus Torvalds - Starting development of the open-source linux kernel.
Have a nice day,
HCDR.Jacob

Nice!!

I will compile this myself later on and upload the zImage for developers to add into their ROMs if they want to save themselves time by not compiling it

Good work!
What is the minimum clock set at? Stock or lower? I'm running mine at minimum 122mhz at the moment, works fine. And can the overclocking be modified using SetCPU or is it locked in the kernel somehow?
BTW, have you had the time to look into some undervolting?
I'm fully aware that you're busy with CyanogenMod and other stuff, I'm just a bit curious
Will probably flash the OpenFire rom this evening to try this out
Lots of questions at the same time, I apologize for that

Good work!
It would be nice if someone could make a ROM for us newbees to install.

any try to flash this?

good work jacob. i have been wishing for an OC kernel and here it is absolute legend, and only 16? good work fella

Hey Jacob,
I have a very importen info about your kernel

Your kernel dont work with the SKN3KY_01 touch panel it seems it only works with the AMTEL panel.
The same bug is posted on OpenFire (the kernel is your source) and WildPuzzle (uses your OC kernel in v8.0.4) thread.
The kernel included in the CN RUU supports WiFi Tether and AMTEL + SKN3KY_01 Touch Panel.
Maybe there is a way to dirty hack the newer kernel until htc will release the source.

oh itś not working for me.. 0050 it is with wildpuzzle 8.0.1(i think)
edit,
sorry it was 0055 that didnt work. But you cant flash 0050 in openfire. AND I cant unpack or mount boot.img. whatś the fs-type?

Ill look into the screen issue, and for those asking about openfire, its the same kernel

[Q] suckerpunch or Firebird over Firefly ???

I'm on Firefly 2.05 and thinking about flashing with other kernel supports oc/uv. Which would be a better marriage, w/ suckerpunch or firebird? Also, I really like the GPS fix on original FF. Will I be compromise the GPS fix if I falsh with a differnt kernel?

you can try suckerpunch because it is updated so often and most of issues will be fixed within days. The kernel does not affect your GPS performance.

you can flash a kernel over an existing one (basically it will replace the existing one).

[Q] intersectRaven's Kernel for CM6.1.1

Hi everybody,
I'm still on CM6, mostly because i want 720p recording, and i have to say that IR kernel give me about 30% more battery life compared to stock CM6 kernel.
Unfortunately I'm not able to use any of the last IR kernels.
If I try to install any of the 2.6.38 based kernel i get a bootloop, so I'm using the last based on 2.6.37 (31 march). With this kernel my battery life is very good, but I can't connect my N1 via USB... the notification does not appear... I think it's a bug.
The kernel I'd like to use actually is the last one at the time of this writing: 2.6.38.4_AVS-CM6_CFS_20110424_1137.ZIP
But even if it is marked as for CM6, i get a bootloop...
Anyone have the same problem? What is the best/last IR kernel for CM6?
Thank you very much and... sorry for my English
Zener79

Use 2.6.35 kernels, they're the last for Froyo, if I remember right. Look at the kernel version explanations in iR's thread, you'll see.

I'm using IR Kernel based on 2.6.37 and it's working fine, except for the USB problem.
What I don't understand it's why for each kernel release the developer still upload kernels for CM6 even if we can't use with Froyo...
I mean...
2.6.38.4_AVS-CM6_CFS_20110424_1137.ZIP it's supposed to be for CM6 and
2.6.38.4_AVS-CM7_CFS_20110424_1139.ZIP it's supposed to be for CM7
but the one for CM6 doesn't work with CM6...
Unfortunately I cannot post on development section, otherwise I would have asked him on the right thread http://forum.xda-developers.com/showthread.php?t=653598

[Q] Intersectraven's kernel??

I would like to know if config_tun is set to Y or M?
thanks in advanced

For most kernels (including IR's), you can extract the .config file from /proc/config.gz

Thanks man. BTW yesterday i switch back from CM 7.0.2.1 to CM 6.1.1 coz of wonk issues and i really want the vpnc app to work. i'm looking for a good battery life kernel currently i'm using WM last kernel version for CM6, if someone can give me a link for IR kernel (latest) that works with CM6.1.1 coz on IR's download page i tried all the kernel's for CM6 eventually i got boot loops and on RS kernel i got FC's & i can't find those with OC/UV. for now i don't have any issues with WM but i really want IR for comparison Thanks

Request tun.ko for Lg Optimus 2X v20l

Hi everyone,
I need tun/tap driver to get openvpn working. I know some kernel/rom have that, like CM, neoblaze, djdroid etc. But I want to keep stock kernel with stock rom because I have tried every roms and the stock one satisfies me the best! But it only lacks tun driver !
Can somebody compile a tun.ko file working with the stock rom and kernel? Thank you.

I've tried and I don't think it's possible. tun.ko requires the kernel to export the symbol "outer_cache" which it does not. (only tegra kernel seems to be missing this as default...). It's an easy fix, but to use the generated module you would have to replace the kernel as well (to one that exports the required symbol)

Thank you for you answer.
I have tried to do that too and wasted 2 hours. I wonder if I do it right. I downloaded not the aosp kernel but the v20l kernel source from http://www.lg.com/global/support/opensource/opensource-detail.jsp?detailCustomerModelCode=LGP990. I used this tutorial http://stevechui.blogspot.com/2011/10/compiling-kernel-modules-tunko-for.html. But the Lg sources doesn't include the tegra folder.
ergoen, you seem to say that you managed to create a tun.ko file with a slightly modified stock kernel ? That would be what I search for.

just flash spica HP kernel SR2 and if you want flash the PP7. it does support tun.ko and cifs.ko already tried. good luck if you want to try (in his kernel it's not module but it's on built in driver)
i use vpn to my office with vpnc connection and it good to go
here is the link if you want to download vpnc connection
Code:
http://code.google.com/p/get-a-robot-vpnc/downloads/list
just download the vpnc connection.apk don't download anything else in there

Or try the Modaco custom kernel r26 with GR5. You can get a nearly stock phone with that.

I can build a kernel based on stock source with tun enabled and provide a cwm flashable.

It's not possible to keep stock kernel and just add the modules as if... You have to recompile the whole kernel and flash it... So why doing this as other kernel based in stock sources are available? Install SR2 kernel from spica and it will be perfect. A you perhaps... Know if you change only kernel it won't affect your /system, so you ROM will be stock like...
Don't waste time trying to make things that have already been made and working.

Because I tested other kernels and even if there are lots of improvement authors do, there are some bugs they introduce (ex: neoblaze => tethering not working, thanatos 4.2 => mybackuppro not working, cm7 => hdmi partialy working, djdroid => changements I don't like, etc) or changements I don't like. That's why I like the principle of using the stock rom/kernel as long as everything works.
I don't know about spica kernel, it's the only one I've not tried with swiftextreme. I will try it maybe later because restoring apps takes some time.

Flashing kernel doesn't touch /data you don't need to restore apps.
NeoBlaze seems not working with 20L. swiftextreme works only with CM7.

Hey there,
i've just built tun.ko vor v20l stock kernel.
Added a "struct outer_cache_fds outer_cache" in tun.c to replace a missing symbol in the stock kernel.
Greetings

Thank you so much tantalus! Although today I just installed Django with spica kernel (so with tun), that file should be usefull to other people!
