[Samsung Galaxy R i9103] ardatdat:
Well, so far, we don't have a separate forum for Galaxy R (i9103) so I need to put in here...

OK, the kernel is ready. I have tested it using Quadrant benchmark, CF-Bench and continuous playing of asphalt6 & dungeon hunter 2 for hours. Smooth and without causing much heat :)

Below are the details of the kernel:

Features

=======

- For Samsung Galaxy R (i9103) only

- Based on Samsung open source, kernel version 2.6.36.3

- Added new frequencies: 1200 & 1300Mhz

- Setting of max 1300Mhz through SetCPU

- All stock frequencies are untouched: 216-1000Mhz

- Expose the voltage settings to be set through SetCPU

- Limit the boot up frequencies to be 216-1000 to avoid unstable boot up

- Simple IO Scheduler

- 2.6.36.4 patches

- Speed up framebuffer copy

- memory copy macros and functions fine tune

- Misc. kernel fixes

- Rooted (embedded su & Superuser.apk)

Q & A

=====

Q: How to flash the kernel

A: Just flash the .tar file using Odin3 PDA (the same as flashing most of Samsung's android phone). Easily search xda forum for Odin3 and how to use it (http://xdaforums.com/showthread.php?t=1262272)

Q: Will it delete all my applications, settings or files?

A: No. (should be..) It is a kernel, not ROM, therefore, nothing would be deleted

Q: What version of ROM is supported?

A: Kernel version is 2.6.36.3, it is proved to work on 2.3.4/2.3.5/2.3.6 ROM

Q: I don't need overclock (OC), can you make a non-overclock kernel?

A: The kernel itself supports max. of 1300Mhz. It doesn't mean that you need to operate in such frequencies. You can freely set your frequencies using SetCPU (for example, you can set 216/216 when screen off, and 216/1000). In such case, no OC will occur

Q: Will I be rooted after flashing this kernel?

A: Yes. I have modified the kernel to make it embedded with su & Superuser.apk

Q: How stable is OC? Will the battery drain fast? Will the phone get hot?

A: For 1200Mhz, it is quite stable. For 1300Mhz, I have experienced 1 program FC. Apart from that, I am using 216-1300Mhz for daily use and it is quite stable. Tested with asphalt6 and dungeon hunter 2 for over an hour, no FC occurs. Also, the battery doesn't feel hot (it is the advantage of tegra2 CPU :cool:)

Q: How can I revert back to the stock kernel?

A: If you have flashed CWM, and you have backup before you flash this kernel, you can choose (advance restore) to restore only the boot.img. Alternative method is to download the rooted stock kernel here (flash through Odin3 PDA): http://www.mediafire.com/?guhb64qy3h6sang

*** I will keep updating this kernel to make it better and better ***

*** Finally, flash at your own risk ***

=====================================================================

From the Samsung Open Source web site, I have downloaded the kernel source for i9103 and made modifications to it. It is good that this phone is equipped with Tegra2 CPU such that overclocking will not cause much heat problem and I can successfully overclocked to 1.3GHz

Below are some screen shots and I will release the kernel later today as I am still testing the new kernel.

For the first version, I will add in rooting (su+superuser.apk), SIO Scheduler, 2.6.36.4 patches and some minor kernel fixes. Stay tuned :D
