from README file :
additional note :
- this patch for samsung's GT-S5360_GB_Opensource_Update2.zip kernel source
- this thread is about patch, not custom kernel. i include kernel test build only to make easy if someone need test it. so please don't request features like a2sd, cwm,etc.
- this patch is alpha quality. i already testing (>2 days) before submit here. but some of patch work on low level system and maybe effect on long term usage. until it fully tested, use only for testing purpose and remove from your device when done.
- i make small mistake in "apply kernel" part on README file inside archive. i already corrected the one in this thread. sorry.

CpuFreq Patch for Samsung Galaxy Y (S5360)
==========================================
what this patch do
------------------
1. add additional freq to cpufreq 624mhz, make it have 3 freq scaling
(312,624,832 mhz)
2. fix bug while reading
"/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies"
that bug make cpu spy not working.
Apply patch
-----------
1. copy all patch files outside kernel source dir. dir should be like this
kernel/common/
kernel/modules/
bcm_cpufreq.c.patch
clock-21553.c.patch
device.c.patch
2. goto kernel/common
$cd kernel/common
3. apply patch
$patch -p2 < ../../bcm_cpufreq.c.patch
$patch -p2 < ../../clock-21553.c.patch
$patch -p2 < ../../device.c.patch
4. build kernel
Note
----
this patch work using clock mode betwen 0xC (312mhz) and 0xF (832mhz) in
file "clock-21553.c". 0xD and 0xE working on same frequency 624mhz. don't
know yet whitch one to use (i use 0xE), so please contact me if you have
more information. right now this patch only effectife if you using
performance (or powersave) with app to control it (like setcpu). not
limitation of patch, but bcm21553 governor look like
ignore scaling_{min|max}_freq.
if you capable, please review my patch. scaling_available_frequencies
related is pretty safe. if you only interested to that part, get it from
file "bcm_cpufreq.c.patch" which call "cpufreq_frequency_table_get_attr"
and "cpufreq_frequency_table_put_attr". the other i am not sure yet. i am
still test it about 2-3 days.
i am not experiance creating patch file, so check file before apply and
tell me if i do it wrong. but patch is so small, apply it manually not
going to hurt you
i include test build (boot-sgy.tar). flash it with odin (pda) if you want
to try. it close to stock kernel only with patch and powersave governor
enable. and like usual, i am not responsible if some thing bad (or good)
happen to you device.
