This is my personal kernel, that I decided to release now. It is extremely lean to minimize memory footprint and optimize perfomance. It is built from HTC official GB sources, with some of bananacakes, siberes, snq-s and my own patches. I intend to keep it at 2.6.35.10, as I see more problems than advantages in upstreaming to newer revisions.
Features:
-Hybrid adaptive voltage scaling (HAVS)
-V(R) i/o scheduler
-TinyRCU
-Overclock up to 1190
-Undervolt
-Ondemand, Virtuous and SmartassV2 governors (I use Virtuous for wake and Ondemand for sleep)
-AXI
-Lowered WiFi voltage
-EXT4 support
-snq-'s Autobrightnessmod (Enable all 10 levels)
-sibere's Battfix
-USB fast charge
-Optional 2 way call recording
-Hardcoded SD Speed Patch to 2048. No need for init script anymore
-Hardcoded highly tweaked Lowmemkiller (3584,4096,8192,20992,23040,25088). Throw away Autokiller and/or init scripts.
To make it more lean, I have disabled EXT2 support. SWAP isn't supported either, as I find it completely useless.
I have added CIFS and TUN as modules. To install, download and extract the file and push it to /system/lib/modules like so:
Code:
adb remount
adb push cifs.ko /system/lib/modules/cifs.ko
adb push tun.ko /system/lib/modules/tun.ko
And add the following line to your modules init script:
Code:
insmod /system/lib/modules/cifs.ko
insmod /system/lib/modules/tun.ko
The kernel comes in 2 flavors. BFS and CFS. Differences between them are here:
BFS - Brain F**k Scheduler
The scheduler essentially handles CPU resource allocation. It controls how the CPU ramps up in frequency and down again when not needed. The BFS version is generally very snappy (possibly more so than CFS) but is an older scheduler. It is designed to minimise latency on low spec'd machines (desktops generally)
Further details here:
http://en.wikipedia.org/wiki/Brain_****_Scheduler
CFS - Completely Fair Scheduler
This particular scheduler is newer than BFS. It is designed to make the best of High end machines (desktops again). In the early days, CFS seemed much laggier than BFS but now there is not too much in it. I am quite happily running a modern CFS kernel and I don't experience any lag issues.
Further details here:
http://en.wikipedia.org/wiki/Completely_Fair_Scheduler
I am aware that the BFS version throws some errors about 'bad cgroup data' in logcat, I haven't been able to get rid of them. I have disabled everything cgroup related in the kernel, but vm still throws the errors. Don't know why. Doesn't seem to impact performance.
I personally use the BFS version, as I find it somewhat faster than the CFS one. I have absolutely no wake lag, and I get good battery time.
Thanks go out to: snq-, bananacakes, sibere, tobi01001, thalamus, eviollet. If I forgot anyone, pls inform me.
CHANGELOG:
V05:
XZ compression
Fixed Wifi sleep
Tweaked OJ settings for better responsiveness (bananacakes)
Changed ramdisk compression method to gzip.
Rebuilt tun.ko and cifs.ko
v04b:
Fixed WIFI. (My bad. Forgot to adapt install script after including new ramdisk.)
v04:
Added Lowmemkiller tweak to ramdisk (3584,4096,8192,20992,23040,25088) No need for Autokiller or init scripts anymore. Over time I will move more tweaks into the ramdisk to minimize the need for init scripts.
Updated BFS to 0.406
Reverted battery gauge polling to 60 secs.
Added Virtuous governor. Virtuous is a highly tweaked SmartassV2.
Removed Lagfree governor again, as I found OndemandX better.
v03:
Hardcoded SD Speed Tweak to 2048. No need for init script anymore
Made 2-way call recording optional. Check downloads
Reduced battery gauge polling from 60 to 5 secs. (Untested)
A few bits more, can't remember it all.
v02:
Added Lagfree governor. Gives me a wee bit better battery, but sometimes lags when listening to music. Maybe I'll remove it again. Tell me what you think.
Added a minor change from tobi01001 to the lightsensor driver. Details here
Hopefully fixed USB fast charge.

Ondemand:
The ondemand governor is the default option used by Android. It scales the CPU speed between the minimum and maximum speeds depending on CPU load. If the system needs more speed, the kernel will rapidly scale up the CPU speed. This is available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point, ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
Smartass:
This is based on the concept of the interactive governor. This is included in some custom kernels. The smartass governor effectively gives the phone an automatic Screen Off profile, keeping speeds at a minimum when the phone is idle.
Interactive:
The 'interactive' governor has a different approach. Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle. When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down to.
This is available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.

Thanks, I'll be testing this! I've been using snq-'s kernel builds but since the OC/UV ones have freezing problems, and gingercakes won't work for me without MASSIVE lag, I look forward to seeing how this works out.

[How to] Adjust auto-brightness on GB Sense ROM
beanbean50 said:

Click to expand...
Click to collapse
You can't find it anywhere, you need to patch your own framework. The framework apk differs for each ROM, and contains each individual user's UOT kitchen mods too... So to be safe, you really shouldn't use someone else's framework.
Anyway, here's how to do it:
http://forum.xda-developers.com/showthread.php?p=17713587
It's pretty easy, as long as you know where your ROM's framework apk is (in internal /system, or in /sd-ext). Also, the thread suggest you put your framework mod in a flashable zip, but it's easier to just boot in recovery, and use adb to remove your old framework and push the new one.
This kernel no longer works with current CM10/AOKP ROMS - PLEASE DO NOT USE
PLEASE READ THIS ENTIRE POST THOROUGHLY BEFORE PROCEEDING...
This is a customized kernel built from SGH-I727 (aka Skyrocket) source code. This ROM has all the fixes from CyanogenMod & Team Chopsticks tree along with some other stuff.
It's very simple to install.
Ensure you've already installed a working ROM
Install Zip from CWM.
Wipe both caches (just to be safe)
Reboot
FSync Control - Courtesy of Ezekeel
FSync Control which can be used to disable the fsync system calls for single files and filesystems (echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled). These fsync syscalls are used by kernel modules and user space programs to flush an I/O buffer (which is in RAM) to disk to make sure that this data is actually savely stored on the disk before executing the next step. Disabling fsync can result in data loss on a crash/freeze since the data is still in the I/O buffer and has not been saved to disk as it should be and can also lead to problems due to race conditions if two or more processes access the same file. On the other hand disabling fsync reduces the number of I/O operations which potentially could reduce the battery drain and also improve I/O performance.

Governors
Wheatley Governor - Courtesy of Ezekeel
http://rootzwiki.com/topic/14685-kernel27-jul-glados-v20-for-jb/page__st__90__p__405813#entry405813
Badass (default)
Badass removes all of this "fast peaking" to the max frequency. On a typical system the cpu won't go above 1080Mhz and therefore use less power. To trigger a frequency increase, the system must run a bit @ 1080MHz with high load, then the frequency is bumped to 1350MHz. If that is still not enough the governor gives you full throttle. (this transition should not take longer than 2-5 seconds, depending on the load your system is experiencing).
You can tweak the Phase 2 (1080MHz) and Phase 3 (1350MHz) via sysfs (if you don't know, then just leave it alone).
NOTE: Due to it's nature, this is not a benchmark governor. It is meant as a governor that gives you a smooth experience while saving battery.
InteractiveX
Created by kernel developer "Imoseyon," the InteractiveX governor is based heavily on the Interactive governor, enhanced with tuned timer parameters to better balance battery vs. performance. The InteractiveX governor's defining feature, however, is that it locks the CPU frequency to the user's lowest defined speed when the screen is off.
Lazy
This governor from Ezekeel is basically an ondemand with an additional parameter min_time_state to specify the minimum time CPU stays on a frequency before scaling up/down. The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand. Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state on a step overriding sampling interval. Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always select the maximum frequency while the screen is off.
GPU Overclocking
GPU is stock clocked at [email protected] & [email protected] (default).
Example: To increase maximum GPU frequency in 3D mode to 320 MHz:
echo 320000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk
Example: To increase maximum GPU frequency in 2D mode to 266 MHz:
echo 266667000 > /sys/devices/platform/kgsl-2d0.0/kgsl/kgsl-2d0/max_gpuclk
echo 266667000 > /sys/devices/platform/kgsl-2d1.1/kgsl/kgsl-2d1/max_gpuclk
Available frequencies:
3D: 320000000, 300000000, 266667000, 228571000, 200000000, 177778000, 27000000
2D: 266667000, 228571000, 200000000
Kernel-based MPDecision
100% kernel-based multi-core decision! (should cpu1 be online or not?)
This replaces your /system/bin/mpdecision binary which is disabled by the CWM flashable.
Check /sys/kernel/msm_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (70000)
delay = time between checks (500)
pause = if something else plugs in the cpu, fall asleep for 10000
scroff_single_core = if the screen is off, don't plug in cpu1 (1)
nwns_threshold_up = runqueue threshold, if this is reached cpu1 will be hotplugged (35)
nwns_threshold_down = runqueue threshold, if this is reached cpu1 will be unplugged (5)
twts_threshold_up = time threshold, this amount of time must have passed (250)
twts_threshold_down = same as above (250)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
(all times are in ms)

Governor scripts
NOTE: Not needed for v6.0.2 or v6.2 and beyond
These scripts will set the CPU0 & CPU1 governors correctly. Using a tool like System Tuner only sets CPU0 to the selected governor, but leaves CPU1 running the default. This was the only way I found to ensure both CPUs had the correct governor set. Basically this overwrites your init.qcom.post_boot.sh script with one that sets both CPUs to the same governor.

"No-Frills CPU control/Pimp my Rom" for different speed governors and I/O schedulers
The custom Kernel for A110 is coming. But till then, you can try out some different clock settings to get you more speed when on games and experiment with speed governors and I/O schedulers with the stock kernel.
Install No-frills CPU control or use Pimp my ROM to change the Min clock(limited to 250 MHz) or Max clock (limited to 1.001 Ghz now) and 5 governors (ondemand, userspace, powersave, hybrid, performance). For optimal battery and speed use ondemand with 1Ghz/250Mhz and noop scheduler. For games, try performance governor. Those who want maximum battery life can try powersave governor....

I think you have not read the post correctly. See the heading...Its not for changing clock speeds...Its for changing governors and I/O schedulers and there is no way you can do that on stock ROM without an external application as there is no settings for that in the stock ROM. And I am not taking anything about overclocking dude And many of the end users are beginners who do not even know these things...
I have clearly mentioned that the highest freq is capped. And it is not useless. We can play with the governors and the I/O schedulers. Read before you comment pal
but all are useless in stock kernel.ask varun if u have any doubt.

You are totally wrong dude..Get your info right. I have been playing with android right from 2010 and have used a multitude of phones Am not a beginner...I do not have to ask Varun on this...Default kernels come with limited speed governors and I/O schedulers that I have listed above, and THEY DO WORK...When you modify the kernel using sources, you can add many more governors and schedulers and also add other functionalities like over-clocking. Think before you post pal
http://forum.xda-developers.com/showthread.php?t=1369817
Read this dude....
And for your knowledge. The default governor and scheduler that our A110 comes set with is hybrid/cfq. That gives the maximum quandrant score of 3000 and above. Try to change it and you will see the difference in performance. The quadrant scores will go down. The settings DO WORK and to get better battery you can compromise on the performance.
Cheers....
m also not new in android..i also used too many android phones.

You mallu?
same here, expand what you are trying to say?
o/c not possible in stock kernel, but yes we can set clock values depending on the stock clock values between 0 - 1ghz (min 250mhz / maxx 1ghz), and even set governers, we need root for doing such actions na? but not possible without root!!!

so can you give me a clean explanation of everything u said on the 1st post?
Yup..plz explain dude.:angel:
in the stock rom/kernel , what settings in "no frills cpu control" is the best for performance and battery respectively ?
the options seen are governors ( userspace , ondemand,hybrid, powersave , performance ) and I/O scedulers (cfq , deadline, noop) ..
will changing these options be effective in the stock kernel ?

FAQ
Q. My phone is running hot!
A. This is usually related to the voltage being too high. Try lower voltage, and try to determine which frequencies are running hot for you. You may need to also restrict your max CPU frequency with SetCPU, System Tuner, Kernel Tuner, etc, if the frequency won't run stably on your phone.
Q. CPU-intensive apps (particularly games) terminate abnormally after a bit of use.
A. This usually means the voltage is a little too low for that frequency. Try to raise the voltage (only 12.5mv at a time) until you find a stable voltage, and let the rest of us know what value is best for you.
Q. My phone won't even boot with this kernel.
A. Sounds like the voltages are too low for you. Try the "STD" version, which uses voltages only slightly lesser than stock.
Q. I want GPU overclocking, but I don't want CPU overclocking.
A. Use the "OC" version, and use SetCPU, System Tuner, Kernel Tuner, etc, to set the max CPU freq you want.
Q. Proximity sensor doesn't work during a call
A. Fixed in version 0.4
How stable is it?
And also, if I read/understood the "main features" right, you limited the CPU to only use 2 cores instead of 4?
I read that you did it for more stability when overclocked, but if this only uses 2 cores out of it's 4, I will be very hesitant to flashing it...
Either way though, this is great progress! We are finally getting a handfull of developers for the Padfone 2! Hopefully we can get Cyanogenmod ported soon aswell!
Great job!

I've been using it for a few weeks, and when I had 4 cores enabled, I found it a bit unstable. With 2 cores enabled only, it flies along due to the higher frequency, and is rock-solid.
Unless you're using the MSM_DCVS Governor (which isn't default even on stock kernel), not all the cores are used except for under high load. Using Interactive, Performance, and other Governors, it usually keeps 3 cores off, and just powers the second one up when doing things. Only when running very CPU-intensive tasks will all 4 cores be used, and the phone will run very hot. If using the MSM_DCVS Governor, it'll continually lower the CPU frequency anyway. These factors are why I've limited the CPU cores - the end-result is a faster, cooler, and less power-hungry kernel.
Nevertheless, I'll upload another one in the next couple of days with all 4 cores enabled, so people can test it out.
First of all nice work here ! Good to see people progressing. As im still bit of a noob and my question maybe quite noobish.
I have NOS installed on my padfone 2 atm and its working flawlessly. Just before I try this I wanted to ask you if this will some way interfere with NOS ?
I would happily be our test monkey if needed
One more time,
Thank you !
Hey first of all this is very nice that you develop kernel to padfone and its nice to see some progress , but i would like that if you make the kernel with 4 cores and little bit smaller clocks ex 1.5 or 1.6 and if you set low freg to somewhere near 100mhz. That would be nice to see

Quad core
I've recompiled the kernel with all 4 cores enabled, and will update after I've done some stress testing. (I won't upload it if it's not stable for me.)
When I tested it a few weeks ago, quad core was too hot, but I've tweaked the voltages quite a bit since then, so hopefully it'll be upload-worthy.
How to download link using phone?
Quad core version uploaded
I've uploaded the Quad core version too.
Curious to here other people's experiences on that - I personally find that my PF2 barely uses the 3rd & 4th cores (even on stock kernel), so I prefer the dual core kernel version (faster, more stable, less heat, less voltage requirements), but CPUs differ a little from phone to phone.
Keen to here people's tests from the dual core kernel vs the quad core kernel.
Me currently testing dual core version
Just downloaded and installed the QuadCore version. Will be back here in a couple of days!
Can you say thank you too many times ? NOT!
Thank you once more !
Thank you for quadcore version wil try it out!

Reboots in Padfone Station
I tried to use the dual core version today during some meetings and it was fine when in phone mode, but after using it in the station for a while it would get very hot and then reboot. I was overclocking it to 1.7. Anybody else have similar experience?

Usually "very hot" means that the voltage needs to be lowered. Can you try using System Tuner to lower the voltage slightly for 1.7ghz frequency, and advise whether that helps?
i have flash the dual core ver.
But when i boot and at the asus loading logo, it keep shining white screen and some color line.
After booted into system it soft reboot again and again. then i revert to stock kernel it fine.
i already wipe cache/dalvik
i am using TWRP 2.5 and stock rom
Undervolting 1.7
I have not tried it in the padstation yet, but the 4 core version undervolted 1 step down (1125 I think?) was stable when I just played Final Fantasy 3 for about 20 mins. CPU spy shows that it was running at 1.7 during that time. No apparent heat issues and no reboots or anything like that. I will try it in the padstation and report back later.
---------- Post added at 03:49 AM ---------- Previous post was at 03:40 AM ----------
Just to be clear I only further undervolted the highest frequency (1.7). Other parts of the table were default for your 4c kernel.
Which app is recommended to overclocking and undervolting?
faZevoLv.kernel
This is a new kernel based off the more stable Hashcodes kernel rather than the previous kernel named thomasin kernel which was based off MWisbest's kernel source which was unstable and caused many random reboots for me and a few other users. This is why this kernel was created, fast, feature packed, updated and most importantly STABLE. no random reboots.

Yeah deep sleep is fixed, in the other kernel it did not go into deep sleep which was where the battery drained.
So when will it be completed? (And if it is completed, when can we download?) I'm itching to test it out.

So how high does the GPU overclock to? And where can I go to change the frequency? Can I use trickstermod app?
BTW, its a pretty good kernel. Nice and smooth. Ever better when I use Seeder. Only thing I noticed was that it reboots every time I try to overclock it to 1747Mhz. 1500Mhz is the most stable for me so I'm sticking with it for now. Keep up the good work!!

ive not added the option to set your own gpu overclock yet, but it will be implemented in a future release thankyou!
Thanks a lot. Very stable and fast so far. I couldn't install double tap to wake. Your old kernel supports this right? Or did I use it elsewhere? Sorry been flashing lots of ROMs lately.
**seems my kindle can't handle a high oc for even short bursts. I set it to 1747 and 10 seconds later it went to bootloop. Shutting it down manually then restarting didn't work. Had to reboot in recovery. But I don't pretend to know precisely what I'm doing.
Have you or anyone else tested above 1500? And if it's working could you share the exact settings? Thanks.

**seems my kindle can't handle a high oc for even short bursts. I set it to 1747 and 10 seconds later it went to bootloop. Shutting it down manually then restarting didn't work. Had to reboot in recovery. But I don't pretend to know precisely what I'm doing.
Have you or anyone else tested above 1500? And if it's working could you share the exact settings? Thanks.

Highest I can go to is 1632. No hiccups so far. Using Interactive Governer with Min Frequency set at 1200Mhz. At the moment I am testing out the new I/O Scheduler that was added, sioplus.

That's what I was doing except with a lower min value and it crashed. Not the system just the browser this time. I'm thinking not all kfhds are created equally.
Overall this has been pretty stable though when I keep it at or below 1500

This doesn't support double tap to wake as it stopped the device from going into deep sleep which caused the huge battery drain, sorry about that.
And yeah I usually stay at 1500, but the option is there for kindles that can handle higher
Not sure if this is related to kernel or ROM (beanstalk) but I'm getting incompatible a lot in play store. I tried market helper but apparently its not ready for lollipop yet. Is there a workaround or like I just considered now--lots of the apps aren't compatible with 5?

Yeah its because a lot of apps don't support lollipop, however most of them can be downloaded from your browser with a quick google search
I know this is way out there a year later, but any plan on updating to 5.1.1 CM based?
