CHANGELOG
CM 10.1 - v2.6 (14 OCT)
Ondemand and dynamic hotplug patches by stratosk
More RAM(790-791MB) (Experimental)
Remove some governors and IO schedulers (lean kernel)
Disable some debugging functions (lean kernel)
Linux 3.0.100

JB - v2.5 (27 JUL)
remove mpdecision
backport stratosk 's nexus 4 ondemand and dynamic hotplug
ondemand: touch_load increased to 1134Mhz for 1.3sec duration
ondemand: touch_load is applied only to CPUs the load is above 35%. So, CPUs with low load (and most probably unused) are not boosted.
These ondemand governor parameters are tunable in TricksterMod
Few patches to improve video overlay
Linux 3.0.87

JB - v2.4 (26 JUN)
"simple" GPU governor by faux123 + patch by franco
"simple" GPU governor set by default ( Currently only fauxclock shows/supports the correct option of simple governor )
Backport ondemand from CAF 3.4 kernel
Set SIO IO Scheduler by default (I did some benchmark tests and found out this is the fastest)
Update latest CM10.1 kernel source
Linux 3.0.83

ICS - v3.7 (15 JUN)
Smoothing voltage table (+12.5/25.0mV if get reboots)
Proper ROW for 3.0.y Linux
Intelliplug by faux123 (experimental) to replace mpdecision
Linux 3.0.82

JB - v2.3 (13 JUN)
Smoothing voltage table (+12.5/25.0mV if get reboots)

Set tweaked ROW from franco.kernel by default
Logger driver update by stratosk
turn on KSM by default
Linux 3.0.80
many misc changes, check github for detail

JB - v2.2 (30 MAY)
update latest CM10.1 kernel source
Linux 3.0.80

JB - v2.1 (20 MAY)
tune some values(e.g. LCD voltage 3V->2.8V) according to leak 4.1 sourcecode
lower the max overclock freq to 1.83ghz
use original fix of stopping the bootanimation
Linux 3.0.79
Some patches & fixes ,check GITHUB for detail

JB - v2.0RC1 (9 MAY)
update latest CM10.1 kernel source
fix bluetooth wakelock [dczz]
update latest mpdecision [showp-1984]
Add max screen off freq to userspace - echo "702000" > /sys/module/cpufreq/parameters/suspend_freq
update mach-msm/cpufreq.c from CAF
Linux 3.0.77

Re: [KERNEL][27 JAN] [P93x|SU640] Wind_Kernel-v3.0 for STOCK/MIUI ICS

I created script to oc gpu, put it in etc/init.d & set right permission but it didn't auto run at startup, the max_gpuclk files still unchanged untill I run the script manually

Honestly, I dunno how init.d scripts execute automatically.
But you may use Smanager, select the script, click the "su" and "boot" and then "run"

Hi lyfkevin!
Have some question. What utils do you using for repack boot.img?
I tried different mkbootimg, unpackbootimg, mkbootfs, split_bootimg.pl but it not working. Using stock cmdline and base 0x40200000 but it not loading. I never have this problem before on my old phone. P930 have some specific?

I forgot where did i get this mkbootimg pack.
I followed this thread from HO!NO!
http://forum.xda-developers.com/showthread.php?t=1566202
And I use command to make boot.img

Code:

./mkbootimg --kernel zImage --ramdisk boot.img-ramdisk.gz --cmdline "vmalloc=450M,console=ttyDCC0,115200,n8 androidboot.hardware=i_skt" --base 0x40200000 --pagesize 2048 --ramdiskaddr 0x41a00000 -o testboot.img

Oh! Thanks! I never before not using --ramdiskaddr 0x41a00000

miroslav_mm · Jan 27, 2013

Made stuff for easy life. :fingers-crossed:
Just use extract.bat for extract and pack.bat for packing. Everything working automatic. If need change cmdline, edit make_boot

ancifil · Feb 5, 2013

After installing it on last Miui 3.2.1 i have only 768 Mb RAM, why?

chatnever · Feb 5, 2013

Thanks, I'm testing it now

cm10.1 wind kernel v1.0 released
not compatible to cm10, dun mess up

Currently CPU1 status is a bit weird, but defintely wont affect daily use. IT CAUSES LESS BATTERY DRAIN
I guess there is interference between kernel based mutlicore decision(msm_mpdecision) by show-p1984 and governor Intellidemand by faux123.

Test required.
My approaches:
1. switching cpu0 cpu1 governor
2. disable msm_mpdecision by "echo 0 > /sys/kernel/msm_mpdecision/conf/enabled"
3. try different mpdecision/intellidemand configurations by kernel tunner
4. terminal "su" "start mpdecision"
PLX dun hestitate to report ur feedback as it helps me to improve the kernel

REFER:
WHAT IS MSM_MPDECISION
WHAT IS INTELLIDEMAND

Man this is awesome 10.1 is crazy fast with this kernel. Will be testing over the next week. Thanks for all your work and contributions to our device.

tried it on my su640. so far so good. I just can't seem to clock it to 1900. oh well its the hardware 1836mhz it more than enough. thanks for kernel. keep up the good work

question. Noob here. I have no idea how to OC my gpu. Any link to a guide?

Check second post :]
U may use faux123 's kernel tool to OC 3D clock

---------------------------------
Anyway, the kernel still under test and far from perfect. give me some time to improve(as I learnt linux and kernel compile in late DEC christmas)

hmm, i don't know if it bug or not, but i stay my phone on idle on night, and after 8 hour i have 31 percent of battery. i hope it's not bug

Sounds like classic CM10.x

kkruglov · Feb 7, 2013

I want to say that after 8 hours as it remained 31 percent.

classic cm 10.x? (i don't understand)

I assumed you said it drained to 31% after 8 hours idle... if that's the case, classic battery hogging CM10.

If you meant it stayed at or near 31% after being idle for 8 hours, then Wow... That's pretty impressive.

kkruglov · Feb 7, 2013

yes, i mean it stayed at 31 for 8 hours (just idle, without wifi or internet connection).
