rohan.kernel alpha builds
for the HTC One XL

Meant for AOSP JB 4.1.X ROMs ONLY
THIS WILL NOT WORK ON 4.2.X ROMS!!!

Features:

Code:

-Overclock-able to 2.0ghz
-Undervolted
-Loads of CPU Governors (recommended: intellidemand)
-Loads of I/O Schedulers (recommended: simple i/o)
-User controllable voltage table based off of sysfs
-XZ Compression
-sweep2wake
-Linux 3.0.57 (latest release from 3.0.x branch)
-GCC 4.7.2 Linaro Toolchain Compilation
-lowmemorykiller fixes
-Tweaked I/O Schedulers
-zRAM enabled
-Tweaked KSM
-Disabled fsync
-Increased readahead buffer
-self-powered OTG support
-NTFS read/write support
-decreased cache pressure for faster fs
-camera app flash till 5%
-various other tweaks for stability and performance

HOW TO INSTALL:
If you are on the older HBoot:
1) Flash the kernel zip in recovery
2) Wipe dalvik cache
3) Reboot and configure it to your liking

If you are on the newer HBoot:
1) Flash the kernel boot.img from the zip using fastboot
2) Reboot into recovery
3) Flash the kernel zip to install the modules
4) Wipe your dalvik cache
5) Reboot and configure it to your liking

Thanks to XsMagical and Team Nocturnal for the video!

What is coming soon:

Code:

-Fast Charge for ROMs that support it (such as AOKP JB)

What I hope to add but no promises:

Code:

-MSM DCVS governor
-GPU control
-Gamma/Color control (tightly integrated... there is loose integration with current 3rd party apps)

What is never coming so don't ask:

Code:

-BS patches and features

Download: http://code.google.com/p/rohan-kernel-evita/downloads/list
b6 and onwards include two versions: a NORMAL version and a NOVC version. First try the NORMAL version. If that does not work correctly, then try the NOVC version, which includes all features except voltage control.

Recommended values:
192mhz Minimum
1.98ghz Max
I/O: sio
CPU Gov: intellidemand

Use an app like No Frills CPU Control and set the values you want at boot.

These are extremely alpha builds. They are not fully tested and may brick your device. If something does happen to your device, you are not to blame myself or any others involved in this kernel. Flashing this is solely your responsibility and if something happens, blame yourself. Always make a backup before flashing. Making a nandroid of your boot partition takes a few seconds but could help you save your device from bricking.

--------------------------------------------------------------------------------------------------

My goal for this kernel is to make it simply an enhanced stock JB kernel.

If you enjoy my work or would like to encourage further development, then please consider donating. All of my money comes from donations as I am currently in high school. They are never required but always appreciated. My link is under my name on the left.

Can I ask why only for AOSP?

Because I do not want to manage 2 kernels at the same time, on top of my three ROMs. I will be including some ramdisk tweaks in the future, and the ramdisks vary between AOSP and Sense.

Because who uses Sense when you have AOSP

Rohan, you gonna implement the kernel into your ROMs once its more stable... and OTG would be great! Awesome work :thumbup:

Nope, I'll be keeping this kernel separate. If a user wants this kernel, then they can flash it on top of my builds

I don't want to force the user to use anything they don't want.

Silellak · Sep 17, 2012

Wow Rohan, you have been busy lately!

:highfive:

Any chance we'll see the additional free RAM from the Android 4.0.4 Sense ROMs, or is that not a kernel thing?

Most probably not, its not worth the effort IMO. Unless its something easy, that is.

Running great on build 2 of AOKP. Got a good solid base here to work with. I would like to say thanks to u and h8 for all the hard work.

XsMagical · Sep 17, 2012

oh hell yea, going to give it a try now

austinsnyc · Sep 18, 2012

Yes if OTG could be made to work that would be amazing, imagien being able to hook up a USB stick to transfer files or be able to use apps that make use of OTG yummy

Getting a lot of reboots... Restored to backup

I must say that I am thoroughly impressed with you rohan!! You are putting in so much blood, sweat and tears into this community, and I (and I know others) are immensely grateful! Keep up the great work! Will try the kernel again beta 2!!!

Yeah I got like 2 or 3 initially but it seems fine. I think it happens right after you tweak the CPU settings. I'll be looking into it.

Nice work thanks. A few reboots for me too.
