HWA Kernel for HD2
My kernel is based on Tytyung's r2.5 base
and mix the KGSL driver from Code Aurora
This is a DEV thread. the latest code may cause some problems.
HTC HD2 is still the KING!!!!
My GIT Repository
Notes:
1. this kernel can't be used in CM7 ROM
2. the current(before 27 Apr 2012) existing android4.0 ROMs can not directly use this kernel, becasue they are not using the correct libs to match the latest KGSL driver.
Update: 4 MAY 2012
Rick_1995 back port all the KGSL , MDP from 2.6.38 to tytung's 2.6.32 and the latest build can be found here: link
Update: 13 MAY 2012
Rick_1995 and tytung made some more progress : link
Update: 19 JUN 2012
Memory tweaks : link
msm: kgsl: Add support for the preamble context flag link
Update: 21 JUN 2012
backport the following items from the latest KGSL driver: link
msm: kgsl: let postmortem dump find context switch IBs
msm: kgsl: fix size checking in adreno_find_region
msm: kgsl: Set default value of wait_timeout in the adreno_dev struct
msm: kgsl: Make sure WPTR reg is updated properly
msm: kgsl: fix error handling in adreno_waittimestamp()

Important Tips : don't turn on the Settings->Developer options-> Force GPU rendering
Turn on this option will cause problem.
23 JUN 2012 update link
change back the pmem size to 32MB adsp_pmem to 41MB this is the default configuration, It seems resolved the crash problem with DesireC GPU libs.
In this version I have already include the DesireC gpu libs in the zip file.
With the new GPU libs the Chrome Browser is very smooth, the hardware H.264 decoder is working.
25 JUN 2012 update
need more people to do the new GPU libs test link
25 JULY 2012 update link
1. ignore the version check in Qdsp6 Vdec which can prevent some crash when the vdec being used.
2. msm: kgsl: Write the retired timestamp on resume
3. msm: kgsl: handle larger instruction store for adreno225
4. msm: kgsl: Add support for the A3XX family of GPUs
5. reduced the PMEM_ADSP size as the HW decoder still can't work on HD2 (now we have 420MB memory for userspace)
6. msm: kgsl: Update the GMEM and istore size for A320
7. msm: kgsl: return correct error code for unknown ioctls
8. msm: kgsl: handle all indirect buffer types in postmortem
9. msm: kgsl: Detach memory objects from a process ahead of destroy time
10. msm: kgsl: Find a mem_entry by way of a GPU address and a pagetable base
11. msm: kgsl: Cleanup header file macros
12. msm: kgsl: Add GMEM size configuration in gpu list
13. msm: kgsl: don't clear gpuaddr when unmapping global mappings
14. msm: kgsl: Do not dereference pointer before checking against NULL
add new GPU libs

I don't really get what you guys mean by "no kernel?" or "no release today?".
The code is there in a GIT repository and as far as I understood the OP the kernel is useless without a matching ICS/CM9 ROM anyways, so it makes no sense at all to release a binary and get flooded with "OMG IT DOES NOT WORK WITH CM7" replies.
If you think you know what to do with this kernel you should be able to set up GIT and a Android compile toolchain and compile it from source. If you need a flashable ZIP, this kernel is useless for you anyways.
This thread is dev/bug collection-related, not a kernel download thread. Wait for Xylograph to release his CM9.
Calm down people, none of the roms available yet use it anyway.
Xylograph in pm (removed few things)
Ok guys,
I think my beta build is amost finished and I will be leaving my workplace soon and go home..
I will be available again in about 4 hours from now to work on it again.. Will check XDA every once in a while..
Cheers !

I could post link to the alpha test rom we used, but it isn't that exciting with most stuff being buggy (some things even worse than current ics roms).
@securecrt, You have done what i was afraid of.. WHY WHY WHY overwrite git data with "first commit", if you had just used git push and git add remote, we could see what you had done without downloading the kernel.

Congratulation that you have added HWA feature to the 2.6.32 kernel.
But I suggest that you may consider re-uploading another version including all the old commits and your changes.
Edit:
Or share your changes by executing "git diff > HWA.diff" or "git format-patch -o HWA.patch".

Hey tytung
I created a diff of latest DORIMANX git and the HWA Kernel git.
Diff is available here https://www.dropbox.com/s/isv8ggyot1kzooa/DIFF-Dorimanx-HD2-2.6.32.X-SecureCRT-HD2-2.6.32.X-HWA.diff
Hi securecrt, thanks for your work here.
I am trying to port Xylograph's ROM with portadroid, as I think you tried with more success than me. Could you post your initrd.gz?
Many thanks
I have a question, can i just take the "lib" directory from the CM9 ROM and add it to the AOKP build you made xlo? would that work? since they are both based off of CM9?

Tytung,
Please make a note that the securecrt kernel DOES work with usb tethering via the wired-tether 1.4 apk where your kernel does not. Perhaps this might help in debugging the issue? "normal" usb tethering brings up the rndis device (your kernel returns a -1 return code at that point) but fails to send or receive data...the wired tether apk gets around the issue and works as normal usb tether should.
I have seen some of the ROM Devs are working on the HWA ICS ROMs . It is really a good start point.
Today is new life for HD2.
Cheers.

Thank you.
It's very helpful.
Edit:
Well, SecureCRT's kernel is based on Dorimanx 6.6C while DORIMANX kernel is 6.6D. So there are something unrelated to HWA.
Anyway, thanks.

If securecrt kernel makes wired-tether working, it should be that Dorimanx updated some code related to the USB driver. Or maybe the CM team updated CM9 (ICS 4.0.4) to make it compatible with old USB driver.

I think you will update your kernel and ROM soon .
how about at the end of this weekend?

Hey, is this kernel just for SD. i couldnt find a flashable zip unless i overlooked something
@securecrt:
Your kernel is awesome, but there's a small detail that jumps to the eye.
I was testing a CM9 rom based on your kernel, that as alot of banding on transparencies.
That defect was caught by Marc IIRC as a small value on the kernel that had to be changed.
Can you confirm this ?
Big Bang
Great news everybody and big thanks to securecrt, Rick_1995, Dorimanx & all the others behind the scenes.
@securecrt
The RAM management issues have been solved yet?
The KSM already enabled now

THREAD CLEANED
Please guys/gals stay ON TOPIC, development related. This is a thread about KERNEL, nor about roms. Please use the 'thanks button'. Do not ask for any ETA. Thanks for your cooperation.
I find a bug in current kernel.
I hope can fix it soon.

FAQs:
My phone sometimes lags when I unlook it. After 1-2 seconds the lag is gone. Is there a way to fix this?
Yes, just set the minimum cpu speed to 245 MHz. The snapdragon cpu is not able to scale from 128 MHz to any given frequency. From 128 MHz it can only scale to 245 MHz and then it'll scale to higher frequencies.
Can we have ZSL (= zero shutter lag) on the HD2?
No. ZSL was created for newer smartphones that have camera sensors that support ZSL.
My phone suddenly can't connect to my Wifi router after updating to this kernel.
Your phone will have a new wifi mac with this kernel. You will need to allow this new mac address if you have mac address filtering enabled on your router.
Have fun with the ICS kernel.

@marc1706
So I installed the 0.1.1 kernel it was very very smooth. So I rebooted the phone but when it restarted my apps were gone. My free space is now at 0 see attached 1st. pic. Running Smokin's MIUI-US-2.5.11-HWA. Is this a kernel problem? Cheers
Edit: My setup also included Setcpu with lagfree governor no profiles 245 min 1036 max I have also installed a2sd. I booted to recovery flashed tytungs-HWA-r2.3-uniMAC and my apps kinda returned. They are all there but not in same order as I had them set to display. Any ideas ?
Edit2:
After being satisfied that my data was ok. I re flashed your kernel and again after reboot same problem. So I'm thinking there is an issue with a2sd and your kernel. Cheers

As someone said Marc for president
I think that XDA have to enlarge number of thanks per day since I have gave only 8 thanks today and Marc, Rick, Securecrt, Rapmv78, SBbryan, Xylo, Tytung and others deserve million thanks
Brilliant kernel overall...everything is working and feels quite snappy, maybe faster than .32 kernel
One issue - I,m using amarullz a2sd script and kernel causes low sound bug ( I reflashed tytung .32 kernel and the sound bug was gone). Fix permissions does not solve the issue.
Cheers

Really? How am I supposed to put Sense into a kernel?
If you are asking if this is an ICS Sense kernel:
I think HTC stopped messing kernels up for sense. If we need something special for sense 4.0 I think I'll soon found out.
If you have issues with A2SD reboot into recovery and make sure to fix permissions and wipe the dalvik cache.
Using the kernel on Xylo's AOKP milestone 5 HWA.
Very good so far, except an FC on Settings ... Wireless & Network ... More
(i.e. APN settings, etc.)
Not a problem as my data/APNs are fine.
Email is FCing too - just re-creating my accounts now to see if that fixes it.
Cheers
EDIT: think I have tytung's 2.3-uM initrd as that was my previous kernel.
doesn't boot ics1.1 on tostidroid 1.1 magldr

Cheers Marc. Did a couple of dalvik wipes and re-created the accounts. Seems to have settled down now. APN settings page no longer FC's now too.
Will continue testing and report back.
On ICS kernel in CM9 nightly (13th May) with app and app-private symlinked to SD EXT. Just flashed the kernel- no issues, no FC, all apps area there and work fine, email accounts work. I didn't clear dalvik cache or fix permissions...

Hi Marc,
Just to confirm a little more testing.
Bluetooth is working perfectly in this kernel. In fact, it's the best I've tried yet for ICS. I have a Nokia BH-505 BT headset, which on tytung's and securecrt's kernels, have always "fed-back" the microphone audio into the headphones, so I can hear myself speaking and get lots of background noise in calls. Yours does not seem to do that. AVRCP stuff is working fine too, so, all in all, very very pleased with your kernel.
Thanks very much for your hard work. Fantastic.

sorry, but I meant sd/magldr boot I understand, that the kernel was not designed for the sd builds.
just for the dev info. that would be great it would be possible to use marc's kernel with sd ics builds.
at least, sense kernel we can use
I'm not sure how the whole SD boot is handled but could try going to services -> Dump dmesg to sd in Magldr after the reboot?
Hello everyone!! Want to try f2fs on your device? You are at the good place to give it a try!

INTRODUCTION
I wanted to port f2fs for our device since it gives a nice performance boost. After few months of learning how to develop and program his own custom kernel here is my first personal release.
This is an open devDB xda project. Feel free to fill in bugs reports, feature(s) requests and reviews.
To those who don't know what is f2fs
F2FS (Flash-Friendly File System) is a flash file system created by Jaegeuk Kim (Hangul: 김재극) at Samsung for the Linux operating system kernel.[2]
The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

Some benchmarks to point out the performance difference between EXT4 and F2FS
AndroGuide benchmarks : ext4 vs f2fs ( seemes to be using the most recent f2fs)
XDA's benchmark : ext4 vs f2fs
Phoronix's benchs ext4 vs btfrs vs f2fs

Compiled with linaro 4.7.4 with optimized flags : O3, etc.
Linux 3.4.67: synced with cyanogen 's manta kernel git, google's common branch, some parts of the kernel updated to 3.4.108, and many fixes from CAF,linaro, blabla.
Governors : interactive, intelliactive,intellimm,conservative, ktoonservative , performance, userspace, nigtmahre(on request)(ask for some others if you prefer them over the one I provide)
I/O schedulers : noop, cfq, deadline, bfq(tweaked for nand devices),fiops,zen,sio
f2fs updated from upstream git(08 september 2015)
UV and OC both for the GPU AND CPU supported
Control for the gpu table thresholds
touchboost driver for cpu and gpu in replacement of crappy powerHAL touch interface ( thx @franciscofranco to have adapted qcom code to ageneric one)
arm optimized crypto algorithms.(for the ones that want to crypt their data)
f2fs crypto support
kernel neon support
kernel side touch boost driver
double tap to wake
AnyKernel2 Solution: Allow users to install the kernel on different distribution. It also detects the filesystem of your partitions to produce a correct fstab. ( f2fs is supported on any partition BUT system )
and many more patches(see my github!)
installation instructions :
Wipe Data Cache System
Flash The kernel
If issues are met, delete the
Code:
/sdcard/Android/data
folder.

How To Migrate one partition from ext4 to f2fs(vice-versa):INSTRUCTIONS FOR TWRP 2.8.x.y
GunnerOnASpooky said:
1. Backup everything from your internal storage to your PC or what ever, if you are migrating /data partition,since the entire internal storage is going to get wiped out with format!!!!!!!!!!
2. Download the recovery from my gdrive
3. Flash the recovery from the bootloader (fastboot flash recovery XX.img)
4. Reboot into the newly flashed recovery
5. Choose wipe, advanced, then select the partition you want to change its filesystems
6. Choose the change file system option on the right
7. Select change file system again
8. Select f2fs(or ext4)
9. Repeat for all you wish to convert (I did system!/data/cache but /system partition should be working if you rom package flash extracts instead of flashing an image)

block:bfq:adjusted tunnables for nand devices
block:bfq v7r7 v7r7: . BUGFIX: Prevent the OOM queue from being involved in the queue cooperation mechanism. In fact, since the requests temporarily redirected to the OOM queue could be redirected again to dedicated queues at any time, the state needed to correctly handle merging with the OOM queue would be quite complex and expensive to maintain. Besides, in such a critical condition as an out of memory, the benefits of queue merging may be little relevant, or even negligible. . IMPROVEMENT: Let the OOM queue be initialized only once. Previously, the OOM queue was reinitialized, at each request enqueue, with the parameters related to the process that issued that request. Depending on the parameters of the processes doing I/O, this could easily cause the OOM queue to be moved continuously across service trees, or even across groups. It also caused the parameters of the OOM queue to be continuously reset in any case. . CODE IMPROVEMENT. Performed some minor code cleanups, and added some BUG_ON()s that, if the weight of an entity becomes inconsistent, should better help understand why.

Awesome work man!
F2FS fully working on System/Data/Cache with SlimKat 5.8 weekly 4.4.3 and your F2FSall Ktoonsez kernel...
Nexus 10 is flying now!
EDIT: I'm getting a bunch of freeze-ups which result into reboots, is this happenng to anyone else?
Steps i took:
fastboot flashed kt-twrp
changed settings (including /system)
wiped what needed to be wiped
replaced Rom script( SlimKat weekly build 4.4.3)
installed rom, correct kernel, and gapps
Any advice would be appreciated!
I have some pb too. It's quite impossible for me to copy something from my usb stick to the internal memory. It freezes almost every time.
No problem in ext4 with same ROM.
Only problems I encountered were freezes/reboots for the very first hours of use, been so far in full f2fs with cyanogen M7 no probs here.
However, did you try with only cache+data partition?
Yep, I was on cm nightlies and data/cache only.
Now I'm trying omni, I will try with this ROM
Could you paste the content of the fstab please?

About the fstab: What updates the fstype for the partitions we choose to convert to F2FS? Is TWRP 'smart' enough to write the proper /fstab.manta? I thought the boot.img in the ROM zip contained this file?
Really excited to switch to F2FS, I've been running it on my Arch boxes for a while now. Anyone worked on an auto updater for the updater-script? I'm on OmniROM and flash daily so it would be nice to not have to hand edit and re-pack the zip every day. I'd look into doing it but I'm not super confident I'd go about it the proper way.

For now, TWRP can detect when you are wiping your partition what tools it would has to use. I.e : if you choose to wipe data partition, system, etc.
And use the correct tool accordingly. But official version do not mount yet however f2fs partition.
The fstab is in the ramdisk, so contained yep in the boot.img. But there are few mount options, some may need to be activated in case of unstability

Thank you for your reply. Perhaps the best thing is to create a flashable zip to be run after ROM flash to install fstab.manta?
Also, FWIW, here's some sed commands to update your updater-script per the instructions in the OP:
Code:
sed -i 's/^mount("ext4".*\/system*/run_program\("\/sbin\/busybox", "mount", "\/system"); /' updater-script
sed -i 's/^format("ext4".*\/system*/run_program("\/sbin\/mkfs.f2fs", "\/dev\/block\/platform\/dw_mmc.0\/by-name\/system"); /' updater-script

Hello I just added some executable java program that convert a rom script to be f2fs compatible.
Also, having less issues with lastest kernel build but I tried it on new roms. ROMs fully working so far and stable : liquidSmooth 3.1 & slimkat 4.9.
Before I was using CM11 M7 it was working but was encoutering some freezes/reboot- especially at the beginning - but then it was ok. I can not tell if this is still happening with cm rom.
I haven't test the pc program on windows if anyone could say it does work, thx!
EDIT : thank to @dust40; he told me the tool was working on Windows as well! Should work on mac too then i guess.
Well I successfully converted /data and cache to F2FS. I made the effort way more work than it had to be by preserving my data. WAY more work. Booted in recovery mode I tar'ed up /data to a exfat formatted usb-otg drive then ran the conversion. Ran into 'value too large for defined data type' errors from tar when extracting. I ended up extracting the tarball onto my workstation, deleting the file it crapped out on, tar'ing it all back up to the usb drive and re-running the extraction. Had to repeat this procedure a good dozen times and I ended up with messed up permissions on all my data. I don't suggest anyone try this because it would have taken much less time to just set up a fresh installation, but if you do here's some good commands to fix up permissions (TWRP's fix permissions command doesn't fix what I messed up). I found these commands at http://forum.xda-developers.com/showthread.php?t=2222297 but had to adjust them a little bit. The chown command has to be run when booted to android, the chmod commands can be run from either recovery or android. Reboot immediately after running. Best to run through adb shell than in an app on the tablet.
Code:
find /data/media/ -exec chown 1023,1023 {} \;
find /data/media/ -type d -exec chmod 775 {} \;
find /data/media/ -type f -exec chmod 664 {} \;
@Khaon, can you ask ktoonsez to compile 4.4.4 versions of the kernels? Latest OmniROM update for manta is 4.4.4 but will not boot with this kernel. And obviously I cannot run any other kernel as none others support F2FS. Thanks in advance! And thanks for putting this thread together. Without your good instructions I probably wouldn't have had the guts to convert this early.
One last thing, I can report that OmniROM works perfectly with /data and cache formatted as F2FS (once permissions are set right!). And since I preserved my data I have an apples to apples comparison of performance and it is noticeably faster and smoother!
kt-recovery stuck at splash screen
Hi,
I had originally posted this in ktmanta thread:
I have been running F2FS on cache+data for past 2 weeks and it works very well (still some strange system freezes, i will need to investigate further on that).
However, now, when i boot to recovery, screen stays stuck at splash screen showing "f2fs enabled by Ktoonsez..", and does not go anywhere else. i can still flash using adb, but clearly, it's less than convenient, and using twrp 2.7.10 is not an option, as it can't mount f2fs sdcard properly anyways.
with adb shell, i can see that all is mounted properly, f2fs or not, but obviously, it's less than ideal... i have attached /cache/recovery/log file .
Note: i connect usb cable 2 to 3 mn after waiting for splash screen to go away, and i pulled recovery log at that moment. this was also the only way to get out of this stuck mode, via 'adb reboot' command.
i also tried to re-flash recovery via fastboot, but that made no difference.
any help appreciated !
@ericp2 @b1g.p0ppa
Can you just try this recovery and tell me if you are running any issue? This is just last official twrp 2.7.1.0.
Just formated and installed a new ROM, ran into no issue, guess should be the same for you .

Well I successfully converted /data and cache to F2FS. I made the effort way more work than it had to be by preserving my data. WAY more work. Booted in recovery mode I tar'ed up /data to a exfat formatted usb-otg drive then ran the conversion. Ran into 'value too large for defined data type' errors from tar when extracting. I ended up extracting the tarball onto my workstation, deleting the file it crapped out on, tar'ing it all back up to the usb drive and re-running the extraction. Had to repeat this procedure a good dozen times and I ended up with messed up permissions on all my data. I don't suggest anyone try this because it would have taken much less time to just set up a fresh installation, but if you do here's some good commands to fix up permissions (TWRP's fix permissions command doesn't fix what I messed up).

Glad you like the kernel running this, if I understood correctly, you wanted to back up the internal storage( so /data/media/0) and your apk folder to an exfat usb drive you mounted with otg? If the fs of this one was exfat that is probably the cause of your issues, I am not even sure our tablet nativly supports exfat( isn't a samsung fs that allows 32GB ++ partition size?). Lastest Omni kernel is booting I assume?

Issue fixed. this version of TWRP starts correctly, and f2fs formatted sdcard can be listed, so i can again flash CM updates.
many thanks!

[GT-I8150][ION] K^Kernel 3.4 for KK 4.4 ION+PMEM ADSP, Kernel for the Samsung Galaxy W I8150
Contributors
Christopher83
Source Code: https://github.com/Christopher83/samsung-kernel-msm7x30/tree/cm-11.0
Kernel Special Features: Customized kernel 3.4.x for KK 4.4 rom (CM 11.0 and derivatives) with ION memory allocations
Version Information
Status: Stable
Current Stable Version: v3.0
Stable Release Date: 2015-04-05
Created 2014-06-17
Last Updated 2015-06-08
Special features and sysfs settings (Part 1):
Here you can find some useful scripts that can be used with the following described features:
Scripts
CPU voltage control VDD sys interface
This feature allows to customize the voltage assumed by each cpu scaling frequency.
It could be useful if you'd like to decrease one or more voltages for battery saving purposes (undervolting), or to increase/adjust them to prevent phone freezes (overvolting).
How to customize the voltages:
1) By downloading and using Trickster MOD or IncrediControl and changing the voltages table inside the SVS tab
2) By using customized init.d scripts (the custom values will be always restored after a reboot, if you don't format the system partition)
- Download one of the script named 01vdd_levels*
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your customized voltages, where each line has this syntax
Code:
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By using Terminal Emulator (note that the values you set will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands
Code:
su
# Run a command for each cpu frequency voltage you'd like to change
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
Alternative Extreme Undervolted (ExUV) settings
If after overclocking your I8150 you noticed some freezes when on ExUV kernel builds, you may use an alternative extremely undervolted setting with the init.d script you can find here: 01vdd_levels_alt_exuv
- Download the script
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
Force Fast Charge
This feature allows you to force AC charging for any charger that is detected as USB (eg. PC USB ports, USB Car Chargers) and pull the full current the charger can support, in such a way as to speed up the time required for a complete battery recharge.
By enabling this feature, the USB / ADB data transfers will be disabled (security limitation to protect your data).
How to enable/disable the Force Fast Charge:
1) By using the related setting inside System->Advanced->Force Fast Charge (only on CM 10 Beta 3 and next releases)
2) By downloading and using Trickster MOD or IncrediControl or NsTools
2) By directly editing the file /sys/kernel/fast_charge/force_fast_charge and setting 1 to enable the force charge, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the force fast charge feature
Code:
su
echo 1 > /sys/kernel/fast_charge/force_fast_charge
- Then, when you want to restore the normal status, run this command to disable the force fast charge feature
Code:
su
echo 0 > /sys/kernel/fast_charge/force_fast_charge
4) By using a customized init.d script, but I don't recommend it because you have to remember to disable the feature every time you want to connect your device to a pc for data transfering after every reboot
Battery life extender (BLX)
This feature has been developed by Ezekeel and allows to set a customized battery charging limit (100% is the default stock value, if you want, you can set a lower value).
As Ezekeel said, it is commonly accepted that both very low and very high charge states accelerate the degradation of the battery capacity (that is why you should store Li-Ion batteries at around 40% charge).
If you set a charging limit equal to 100, this feature will be disabled.
How to activate this feature and set a customized charging limit:
1) By downloading and using Trickster MOD or NsTools by setting the customized battery life extender charging limit
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 15blx
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred charging limit (the downloaded script will set the charging limit to 95%)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/misc/batterylifeextender/charging_limit (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands (changing the charging limit = 95 with the preferred one)
Code:
su
echo 95 > /sys/class/misc/batterylifeextender/charging_limit
LowMemoryKiller
The LowMemoryKiller driver is used to kill a selected process and free the memory when it is under one of the defined thresholds.
The tuning of the driver could be achieved by means of two parameters exposed by the kernel module via sysfs interface:
- /sys/module/lowmemorykiller/parameters/minfree
This file includes a comma separated array of the threshold numbers for minfree memory size (in page units).
The parameter value set for K^Kernel is "2048,4096,6656,9216,14336,19456".
- /sys/module/lowmemorykiller/parameters/adj
This file includes the comma separated array of oomadj factors, if the corresponding minfree threshold has been reached, one of the process with an oomadj greater than this number will be killed.
The oomadj factor is a property associated to each process, its value is in a range from -17 to +15, the processes with a higher oomadj factor will be the first to be killed when a specific minfree threshold has been reached.
The parameter value set for K^Kernel is "0,20,50,100,250,500".
Frandom - Fast Random Generator
As Eli Billauer (the creator of this module) said, Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
How to test if frandom builtin module is correctly working:
- Download the script named frandom_test.sh
- Using your preferred file explorer, copy the file inside the folder /data/local of your device
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Open Terminal Emulator
- Run this command
Code:
/data/local/frandom_test.sh
You should see a result similar to this one:
If the urandom tests take more than 1 or 2 seconds and are more different than related frandom tests, then the random number generation is not fully optimized for your currently used kernel...
How to disable / re-enable the redirection to frandom module during boot process:
By using Terminal Emulator:
- Run these commands to create the flag file and disable Frandom redirection:
Code:
su
touch /data/frandom_disabled
- Or run these commands to delete the flag file and re-enable Frandom redirection:
Code:
su
rm /data/frandom_disabled
The change will take effect after a reboot.
RAM Console
This feature is useful expecially for development and debugging purposes, when occurs kernel panic / unexpected shutdowns or reboots. Pratically, the kernel messages are also stored inside a little RAM portion and restored during reboot after a kernel panic, inside the file /proc/last_kmsg.
Dynamic FSync
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Dynamic dirty page writebacks
This feature has been developed by me and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss), I preferred to use a customizable higher dirty page writebacks interval (15 seconds) than the default one (5 seconds) while the screen is on and a customizable default interval (5 seconds) when the screen is off.
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default enabled):
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
In my kernel builds, during boot, I set other customized values:
- an interval of 30 seconds while the screen is on
- an interval of 10 seconds when the screen is off
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
su
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
su
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
su
echo "3000" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_suspend_centisecs
Special features and sysfs settings (Part 2):
Timer slack controller and dynamic management of the minimal timer slack value
The timer slack controller is a feature developed by Kirill Shutemov and it allows to set the minimal timer slack value for every process contained within a control group (cgroup).
A timer slack allows the kernel to manage processes wakeup requests at some future time.
Thanks to this feature, the kernel can set a specific timer slack for the involved processes, minimizing the number of wakeups and allowing a lower system's power consumption.
For further info: Timer slack for slacker developers
I also implemented a new feature in addition to the above one that allows the dynamic management of the minimal timer slack value.
So, it's possible to use different minimal timer slack value when the system is active and when has been suspended.
How to customize the dynamic timer slack controller feature:
Three new cgroup parameters are exposed inside each processes hierarchy contained in /dev/cpuctl path:
- timer_slack.min_slack_ns is the timer slack used when the system is active for the current processes hierarchy
- timer_slack.min_slack_suspend_ns is the timer slack used when the system is suspended for the current processes hierarchy
- timer_slack.effective_slack_suspend_ns is the timer slack currently used
At the moment, the values chosen and used by K^Kernel are the following:
- core processes (/dev/cpuctl), 0 ns when the system is active, 50000 ns when the system is suspended
- foreground apps/processes (/dev/cpuctl/apps), 0 ns when the system is active, 250000 ns when the system is suspended
- background non interactive apps/processes (/dev/cpuctl/apps/bg_non_interactive), 100000000 ns when the system is active, 250000000 ns when the system is suspended
1) By directly editing one of the file written above inside /dev/cpuctl and inside each hierarchy subfolder, by setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands to set the minimal timer slack for generic and core apps/processes
Code:
su
echo 0 > /dev/cpuctl/timer_slack.min_slack_ns
echo 50000 > /dev/cpuctl/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in foreground
Code:
su
echo 0 > /dev/cpuctl/apps/timer_slack.min_slack_ns
echo 100000 > /dev/cpuctl/apps/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in background and non interactive
Code:
su
echo 100000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_ns
echo 250000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_suspend_ns
LowMemoryKiller management of not killable processes
This feature allows to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
This feature exposes four new lowmemorykiller parameters:
- donotkill_proc, is the flag to enable / disable this feature for the processes chosen by the user
- donotkill_sysproc, is the flag to enable / disable this feature for the system processes chosen by the user
- donotkill_proc_names, is the list of process names (comma separated) chosen by the user to be preserved from killing
- donotkill_sysproc_names, is the list of user system process names (comma separated) chosen by the user to be preserved from killing
When the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
How to customize the white lists of processes to preserve from killing:
On K^Kernel the feature is enabled by default and the provided processes white lists are the following:
- donotkill_proc_names = "com.cyanogenmod.trebuchet,com.anddoes.launcher,com.teslacoilsw.launcher,org.adwfreak.launcher,gtp.nextlauncher,android.inputmethod.latin,com.touchtype.swiftkey"
this means that Trebuchet Launcher, Apex Launcher, Nova Launcher, ADW Launcher, Next Launcher, stock keyboard and SwiftKey keyboard will be preserved from killing
- donotkill_sysproc_names = "android.process.acore,com.android.phone,com.bel.android.dspmanager"
this means that the system process, the phone process and DSP Manager will be preserved from killing
1) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 80dnkp
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred status and processes list
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
2) By directly editing the files inside /sys/module/lowmemorykiller/parameters (note that set values will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands if you want to enable the feature
Code:
# To enable this feature for the processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To enable this feature for the system processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run these commands if you want to disable the feature
Code:
# To disable this feature for the processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To disable this feature for the system processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run this command if you want to add, for example, Trebuchet Launcher (CM default launcher) and the default keyboard to the processes white list
Code:
echo "com.cyanogenmod.trebuchet,android.inputmethod.latin" > /sys/module/lowmemorykiller/parameters/donotkill_proc_names
- Run this command if you want to add, for example, the system process, the phone process and DSP Manager to the system processes white list
Code:
echo "android.process.acore,com.android.phone,com.bel.android.dspmanager" > /sys/module/lowmemorykiller/parameters/donotkill_sysproc_names
ZRAM module
As explained on Wikipedia, this feature, provided in this kernel as a standalone loadable module, increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive.
In few words, the memory pages no more used and so to be swapped are sent to zRam device blocks, compressed and stored in memory instead of disk allowing better performance and also lower memory usage, on the other hand, a little higher amount of cpu is needed to perform compression and decompression of memory pages.
Since we have a device with a low amount of free memory, this feature could be useful to have more free ram.
How to change the size of zRam or to disable it (thanks to @ktulu84 for sharing these scripts):
To change the size of zRam (the custom value will be always restored after a reboot, if you don't format the system partition):
- Download the script named 60zram
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred zRam size (change SIZE value, default is 100 MB)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
If you want to use default zRam size, simply remove the file placed inside /etc/init.d and reboot.
To disable zRam (the custom value will be always restored after a reboot, if you don't format the system partition):
- Download the script named 60disable_zram
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
If you want to re-enable zRam, simply remove the file placed inside /etc/init.d and reboot.
FAQ - Frequently asked questions:
Q: What are the differences between EXUV and UV kernel versions?
A: The EXUV kernel versions have extremely undervolted settings for the cpu frequencies, they allows to have a very low battery drain, instead the UV kernel versions have undervolted settings a bit higher than EXUV versions, but always lower than stock kernel settings.
The EXUV kernel versions could give some problems (freezes, shutdowns, huge lags) on some devices because the cpu doesn't support too low voltage settings.
For a lower battery consumption, I suggest you to try EXUV versions first and to switch to UV versions only if you encounter one of the above mentioned problems.
Q: What are the differences between 396MB, 406MB and 416MB versions?
A: 396MB, 406MB and 416MB kernel versions have different free ram available for user space, with a higher free ram your device will work better with heavy apps, many concurrently used apps, heavy games, etc.
- 396MB versions are more stable, everything is fully working, but you could have some slowdowns with apps that require a high amount of free memory.
- 406MB versions have additional 10 MB of free ram, they are suitable for the users that use the device primarly for calls, messages, simple apps and simple games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
- 416MB versions have additional 20 MB of free ram, they are suitable for the users that use the device also with heavy apps, various concurrently used apps and games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
Q: Why should I deactivate KSM (Kernel Samepage Merge)?
A: KSM (Kernel Samepage Merge), let us save a bit of RAM space used by kernel (max 10MB during my analysis) by merging duplicated memory pages used by different processes, but it has also some performance impacts, since it uses CPU time to perform those memory scanning and merging operations.
So, in few words, it could free up a bit of RAM, but sometimes keeps the CPU busy to complete its work.
After introducing the dynamic allocation of MM ION and PMEM ADSP heaps, KSM could cause issues while trying to use camera or camcorder and playing HW/HW+ videos.
This is due to the impossibility to allocate one or more memory pages that have been merged by KSM inside the memory area reserved for dynamic allocations for MM ION or PMEM ADSP heaps through CMA (Contiguous Memory Allocator).
I'm looking for a solution for this "incompatibility", but at the moment the tried changes didn't work.
So, as a workaround, don't activate KSM until we find a fully working solution, since the RAM freed by dynamic allocation is surely higher than KSM freed RAM without any performance impact during normal usage.
The option can be deactivated inside Settings -> Performance -> Memory management -> Kernel samepage merging.
Q: How can I get the Performance and Developer Options entries inside Settings menu?
A: Go inside Settings -> About Phone -> Scroll down and tap 7 times on Build number (it's an Easter Egg).
Q: How can I get the log after an unexpected shutdown / reboot?
A: After an unexpected shutdown / reboot of the device, if the problem may be kernel related, you should have the /proc/last_kmsg, if so, send me that log and I'll check it to find the possible cause of the problem.
Q: How can I get the logs when I encounter strange system issues while it's running?
A: Check first if the problems could be related to an app you're using and if you changed something in the last days before facing those issues.
If the problem started after installing the kernel, then let me have you logcat and dmesg:
- Open Terminal Emulator and execute these commands:
Code:
su
dmesg > /sdcard/dmesg.txt
locat -v time -d > /sdcard/logcat.txt
- Open you preferred file manager and go inside the internal sd card partition /sdcard
- Send me the dmesg.txt and logcat.txt files, if you want zip them first
Q: How can I mount a shared Windows folder with CIFS module?
1) By using Terminal Emulator
Code:
mount -o unc=\\\\[COLOR="DarkGreen"][I]ip[/I][/COLOR]\\[COLOR="Blue"][I]share[/I][/COLOR],noserverino,username=[I][COLOR="DarkOrange"]user[/COLOR][/I],password=[I][COLOR="Lime"]password[/COLOR][/I] -t cifs //[COLOR="DarkGreen"]ip[/COLOR]/[COLOR="Blue"]share[/COLOR] [I][COLOR="DarkSlateGray"]/mnt/cifs[/COLOR][/I]
2) Downloading and using CifsManager and configuring the new share as follow:
- Share Path = ip/share
- Mount Point = /mnt/cifs/share
- Username = username
- Password = password
- Options = unc=\\\\ip\\share,noserverino
Where:
ip is the ip address of your pc where the folder is shared
share is the shared folder name
user is the user name that can access the shared folder
password is the user password
/mnt/cifs is the mount point (must be created if you'd like to use the command approach with Terminal Emulator)

Do these filesystems actually function? I added these to my own kernel in testing and could get none of these working. I also added NTFS with write support and that did actually function correctly. I'd love to see CIFS or NFS working, along with F2FS and/or EXT2.

missed NTFS support adding that now, they should mount but selinux probably needs to be disabled because it blocks it

Here is v3 with NTFS support added in:

try and mount a NTFS drive and report back, also do setenforce 0 to disable selinux

Confirmed, NTFS works with my 4TB western digital mybook.
Kernel Update
Unleashed V4:
Zram set to 512MB as default on boot in fstab, was 90mb before which was pointless, now less redraws and better memory performance.

I just compiled the kernel for external usb webcam support:
Code:
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L2_COMMON=y
CONFIG_USB_VIDEO_CLASS=y
CONFIG_VIDEO_MEDIA=y
CONFIG_V4L_USB_DRIVERS=y
CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y
but it would seem there is something missing in android tv that doesnt allow it
Excuse the noobness here, but with NTFS support, does this mean we can plug in an ntfs usb drive and it will be seen as system drive and install apps to it?

This would require some fstab editing on your part, just use stickmount and there may be an apps2sd app that could do it, or possibly a symlink, selinux will be need to set permissive as well
Kernel has been running great so far. Your efforts are appreciated. How is the kernel looking for overclocking?

I probably won't add overclocking for a while, the CPU is more powerful than anything ATM, for now I'm focusing on io/memory tweaks, since that seems to be the bottleneck, I will be adding as much as possible, and will keep this updated with the latest kernel code available.
