Installation instructions
First Install:
Install TWRP 2.8.7.0 or newer
Wipe cache, dalvik cache, system, data
Install the ROM
Optional step:
- Install gapps
- Install SuperSU 2.52
Reboot into the ROM
The first boot will take longer than Android 4.4.4 and older ROMs. Android Runtime (ART) is slower than Dalvik at optimizing applications the first time.
Optional steps...
To enable voice calling:
Install I9103XXLQ3 modem (Thanks to Lucas Kado):
[MOD][09.09.2012] Enable Voice Call For ROMs Based ON [Stock ICS & CM9 & CM10 & AOKP]
To enable SELinux enforcing mode:
The default SELinux mode is Permissive. Flash the "Set_SELinux_enforcing" zip to enable full SELinux enforcing mode.

Update to Android 5.1.0_r1
- Install TWRP 2.8.5.0
- Do a full wipe then install the ROM.
- Default SELinux mode is Permissive. Install the "enforcing" bootimage if you want to enable SELinux.
Notes:
I did not merge Android 5.1.0 into my 5.0.x sources. The necessary changes were cherry-picked from my 5.0.x sources on to the new Android 5.1.0_r1 sources.
I've gone back to using the AOSP repositories for Bluetooth/bluedroid and frameworks_av instead of CyanogenMod. I don't know what their timeline is for moving to CM-12.1.
The 3G parts from OmniROM have been updated. I hadn't bothered to update it previously out of fear of breaking it. I only have the WIFI tablet so 3G is untested.
Most other things should be working the same as with the AOSP 5.0.x ROM.
Other Changes:
bionic: libc: tegra: Switch some parts from Generic to Cortex-A9
boringssl: Remove client-side support for ServerKeyExchange in the RSA key exchange. (CVE-2015-0204)

PowerHAL: Update for Lollipop

If there are any problems with the new audio HAL then please save a logcat of the problem and send it over! If we can get it working without many problems then we can get rid of the old ICS audio blobs forever. This will make it easier to port present and future ROMs.
To go back to the old ICS audio just install the p75xx-ICS-AudioHAL-20141222.zip package.

FAQ and common problems
* How to root the ROM
Install TWRP
Install ChainFire SuperSU zip in recovery.
Video / audio issues
* Chrome crashes when playing videos
It is a bug in newer versions of Chrome. Only Google can fix it. Use Chrome 29.x or older for HTML5 video playback.
Update - 2015-05-14 - Chrome version 42.0.2311.111: HTML5 videos are not crashing but they only work in full screen mode.
* Low sound volume with Lollipop audio HAL
Use Voodoo Sound app to increase the headphone amplification.
* Youtube video freezes but audio still playing
Set quality to 480p or less.
* Can we fix laggy video playback? Can we fix Youtube HD video?
No
* Why can't we fix video playback?
The video drivers and codecs are closed source. We cannot modify it. We cannot debug it.
There are no other video drivers or video codecs except for the ICS drivers and codecs. Video streaming technology advances but we are stuck with old drivers and codecs from ICS.
* Can we use ICS / Jellybean / Kitkat video drivers?
We have always been using ICS video drivers. There is no other driver.
Every ROM for this tablet is using the ICS video drivers.
Every single one. No exceptions.
* Youtube HD worked with ICS ROM. Why doesn't it work now?
The drivers are outdated. The video drivers are from 2011. The recent Youtube app is using 2015 streaming technology.
* Can we write new drivers? Can we update the drivers?
No. There is no open source code. There is no technical documentation. We can't do anything without both of those. There is no where to start from. There is nothing that can be modified.
* Why is there no open source code or technical documentation for video drivers?
They are closely guarded NVidia secrets. They will not release it to the public.
Misc. issues
* Can't mount USB storage. How to mount USB storage?
Use StickMount
* TRIM does not work. (fstrim : FSTRIM: Operation not supported on transport endpoint)
TRIM is disabled due to the eMMC "SuperBrick" bug
* Undervolting
Use this at your own risk!
The only app for voltage control that is officially supported by this kernel is SetCPU.
Most apps use the same kernel interface for voltage control but none of the app developers agreed on a standard interface. For that reason it is impossible to support all apps. Do not use any other app for voltage control.
* Do CyanogenMod themes work?
* Do Touchwiz themes work?
* CM-12 themes?
* CM-11 themes?
No.
* Swipe gesture not working with stock keyboard.
Swipe gestures will not work with the stock keyboard. Install the Google Keyboard.
It requires a proprietary library from Google. This closed source module does not work on this tablet.
* I have some other problem.
Send me system logs and describe in detail what the problem is. See Problem Reporting Steps below.
Problem reporting steps:
How to send system logs:
Root the device by installing ChainFires SuperSU.
Install SysLog.
Reproduce the problem.
Open Syslog app and save the Kernel Log and Main Log.
Send me the log files stored in /sdcard/Syslog.
Share the files on Dropbox or another similar site.
Then PM me a link to the files. Please describe exactly what the issue is.
Damn! I definitely wasn't expecting this so quickly since it took so long for KK to arrive for our tab. Thanks a lot for this. Hopefully we can see a p4 build since it has almost the same source tree as p4wifi. Even if we can't, I'd still be flashing this on my p4.

The performance is similar to Kitkat. It didn't get much better or worse.
It's that weird time of the year again where my old GT-P7510 is going to run lollypop before my Nexus receives it's ota! ?
Small question, I did my twrp backup and downloaded everything. Now, can I just restore my cm10.2 backup is I don't like how lollypop runs on my tablet?
Sent from my Nexus 7 2013
Edit : I flashed the gapps and its all good. I guess there is no way to make the tab faster though right ?
Hi
I just tried to flash this rom.
When I flash it the first time I couldn't do anything (ie open the browser, open play store etc). Every app was crashing.
I then tried to flash it twice in a row. The problem is after flashing it once, TWRP disappeared when I tried to boot the recovery. Instead I had the dead android with a read triangle with a "!" inside.
Anyone can help ?
Thank you for helping and thank you to the developer that cooked this.
Wow, thank you for your great work!

I have never used the backup and restore features. I've only tried it once just now and it worked. I wiped before restoring a backup of cm 10.2.

So TWRP was still okay for you after when you installed the zip twice? It should not have flashed over the recovery in any case. There is no recovery included in this package. Unless I've done something wrong but tested it quite a few times by now.

Sorry I realise I was not clear.
What I did:
Full Wipe
Install TWRP
Install rom
Reinstall TWRP
Reinstall Rom
Install TWRP
Flash gapps
It works very well for me =) Smooth and fast for now.
What I did :
- Install clockworkmod 6.0.6 with Odin
- Install the ROM twice
- Reboot
- Reinstall clockworkmod (don't know why it crashed)
- Install GApps
I was running the original ROM before and it seems to be faster now.
Thak you for the great job !

Same problem here, TWRP is gone... :crying:
I'll try flashing the recovery with odin..
Uhh I'm having a different problem. I can't flash the ROM zip at all. Tried with TWRP 2.7.1.0 and 2.8.0.0. In recovery it says error executing update binary. I checked the log and it said 'line 4 col 150: unknown function "block_image_update". Did I miss something? Flashed the p4 version BTW.

PLEASE POST QUESTIONS THAT ARE NOT DEVELOPMENT RELATED IN Q&A HERE. THIS WILL HELP KEEP THINGS TIDY
BEFORE POSTING, ENSURE YOU READ POSTS #1-3 AND SEARCH THREAD FOR INFO FIRST. THANK YOU FOR YOUR ASSISTANCE
BUGS
[Q] Duplicate proc/last_kmsg files
[A] Doesn't appear to affect anything, looking into it - apparently only from v0.8 and up
[Q] Synapse: AUDIO: HP equalizer does not work
[A] Toggle the control switch off > apply > on > apply >then it works
[Q] GPU Qos has this error:
[A] Don't worry, it wont hurt, and will only show if GPU freq 100 MHz is not in use. If you set 100 MHz and restart synapse, control will be available without error.

AUDIO: set all SP equalizer settings to zero
disable SP equalizer
apply
"SYNAPSE BOOT CANCELLED"
Wait for the kernel to stabilize and device to cool
Open synapse app
Synapse app menu > select all globally > undo > apply
Re-boot
If still issues > try again after #1
Still issues > Manually set config after boot (open synapse app > syanapse app menu > settings > disable apply on boot)
ISSUES
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLTAGE OR FREQUENCY FROM DEFAULT !!
Uninstall any CPU control apps, tweaks and scripts etc.
Install Wanam DVFS disabler for greater kernel control
Flash kernel
Boot and allow things to stabilize
Open Synapse & tap :
"understood" message about unstable boot
"select all globally"
"undo" button
"apply"
make any change
"apply"
Reboot and ensure "synapse boot completed" toast message
You should be good to go
BOOT-LOOP
Power off & let device cool
Wipe cache & dalvik-cache in recovery (if custom recovery)
Re-flash kernel
Re-boot
Let things stabilize and cool before touching anything
BETTER BATTERY LIFE
There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
This kernel is built to be balanced with a good mix of battery whilst keeping performance
Decrease screen brightness
Use dark wallpapers and app themes
Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background
Suggest:
CPU GOV: governor = ondemand (tweaked for power efficient workqueues)
CPU FREQ: 200 > 1900 MHz (-25 mV for all)
Synapse: CPU MULTICORE: Hotplug CPU UP boost = 30 %
GPU: 100 > 480 MHz (-50 mV for all) (100 MHz may induce some GUI sluggishness)
GPU: Midgard Power policy control = coarse_demand
GPU: Midgard Power policy threshold control = Battery (may induce some GUI sluggishness)
PowerSuspend Driver = Enable
MEMORY: Dynamic FSync = Enable
MEMORY: Dirty Page Writeback = Enable
CPU Multicore Power Saving = (2) Agressive
BETTER PERFORMANCE
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLATGE OR FREQUENCY FROM DEFAULT !!
Disable DVFS with [APP][Android 4.0+][DVFS Disabler]
Warmer device under heavy load, but within the safe CPU temp of 95 degC
Synapse: CPU FREQ: 500 > 2000 MHz (2100 not stable for some devices)
Synapse: CPU MULTICORE: Power Efficient WQ = disabled
Synapse: CPU GOV: use Interactve governor
Synapse: GPU: set Midgard Power policy threshold profile to Ondemand or Performance. This will scale your GPU up/down faster at the expensive of battery life compared to Battery profile.
Synapse: GPU: GPU max freq = 533 MHz (more if your device is stable)
Synapse: MEMORY: UKSM = enabled
Synapse: ADVANCED: LMK profile = aggressive
GPU THESHOLD CONTROL
Set Midgard Power policy threshold profile (This determine how your GPU freq scales up/down):
Battery = battery friendly
Ondemand = Good all-round mix
Performance = A little agressive
Method:
Ensure you apply [] any changes to MIN / MAX GPU freq or GPU GOV Threshold profile
PRESS THE "Apply GPU GOV SETTINGS" button !!
Settings will be applied immediately and auto set on every boot.
HOW TO BACKUP YOUR STOCK KERNEL BEFORE FLASHING SkyHigh KERNEL
Boot into TWRP Recovery
Select Backup
Select "[X] Boot" only (boot.img/kernel)
Select Storage > Micro SD (if external sdcard installed) > OK
Swipe to backup
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
HOW TO MONITOR LIVE CPU & GPU VALUES
CPU load & freq - available RAM - GPU freq - CPU temp - most resource intensive process
[APP][2.1+] Cool Tool
Download my personal cooltool_presets > unzip & copy folder to INTERNAL sdcard. If you have cool tool app already running, you must disable > overwrite existing folder > enable
LITTLE CORE CPU FREQUENCY
Real frequency is apparently double that reported by other apps
Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DO NOT KILL PROCESSES
This feature allows the user 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.
When a 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.
You can find the [SkyHigh/Synapse] folder on your internal sdcard and add one process name per line. Lists updated on reboot.
Max 25 processes
Example only:
Code:
com.ea.games_r3_row
com.quoord.tapatalkxdapre.activity
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
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)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

BACKUP & RESTORE
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
Reboot after applying your new settings
Read "ISSUES" & "SYNAPSE BOOT CANCELLED" above
TCP/IP NETWORK SECURITY
* Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

SEGMENTATION FAULT
I don't believe it's kernel related, but rather busybox
Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/details?id=stericson.busybox and reboot.
Re-flash kernel
Use the busybox that comes with the kernel located in /sbin
Also try to update your SuperSu and su binary if it asks and reboot.
USB KEYBOARD / MOUSE
Base project: https://github.com/pelya/android-keyboard-gadget
Required app: USB KEYBOARD
For best results, enable & use Hacker's Keyboard
Steps:
Ensure device USB debugging
Connect device to system via USB cable
Enable in Synapse > USB > USB Keyboard / Mouse >> Enable & apply
Start USB KEYBOARD app
BATTERY SCALING CALIBRATION - FUEL GAUGE RESET
Tap [Fuel-Gauge reset] in synapse BATTERY section
Reboot device
Battery % "reporting" calibration (digital)
a) Deplete battery to 5-10% (NOT ZERO)
b) Charge UNINTERUPTED until FULL (don't touch)
c) Unplug and then use normally. Device should then re-calibrate itself

Hi @UpInTheAir
I just had a small question you firmware is based on the ANG2. (CHN) right I had the ANFB. On a T800 wifi with stock rom I didn't like the other roms so far but I want to try your firmware not sure if flashing yours can break my tab . Do you had any subjections?
Thanks for sharing your work

No, source is Japan.
The ramdisk is ANG2 from China.
I don't have a 10.5" device so can't really comment except try for yourself. If you're worried, just back up your data (titanium backup app) before hand along with boot.img for your device (TWRP) to exSdCard. The kernel may or may not work properly on older firmware such as FB etc. Up to user to try for yourself.

Thanks mate I will try tomorrow morning thanks
Hi
I tried it, and to be honest, I don't feel any improvement currently, I guess I need to use it some days to check.
I tried Antutu Benchmark, just to see... No matter settings I try in Synapse, default, or boosted CPU/GPU, results are lower with SkyHigh kernel.
~34500 with Stock Kernel
~33000/33500 with SkyHigh Kernel
Thank you

You might need to read Post #3 again, and the last few pages of the 8.4" kernel thread regarding heat and throttling.
I have said before that we might need newer source and I can't do magic with that. My older firmware + SkyHigh kernel (older source) scored 36200 standard AnTuTu (edit: just with GPU OC) but I don't really care. I don't live for the benchmark, and I certainly don't see any negative impact on general use
There are other features to the kernel, and if they don't suit user needs, I've included the stock kernel for download
Other than that, we just need to wait to better firmware and source.
I did read the #3 post, don't worry I was not trashtalking
Of course I see there is other interesting features
Again, thank you for your work

I realize that, no worries Just edited previous post.....
This newer firmware just runs hotter with older & newer kernel source. Throttling is induced earlier > decreased benchmark performance. Maybe a newer ROM or kernel source will help, time will tell.

I don't have the time or desire to expand on the commitments I have already (particularly for yet another device I don't use). There is no "porting", but would need complete build and patch from source for your own hardware .......

ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
NO - I will not build for any device that I can not compile using same source, personally test method or debug
Otherwise, please do not bother asking
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Two choices:
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox ( v1.23-1-Stericson works for me on stock ROM)
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.
If you wish to restore to a working system, just restore your boot.img backup made previously with recovery (ref: Installation Instructions)
CONFIRMED WORKING STOCK BASE FIRMWARE
T700: XXU1BOE3 or XXU1BOE4 (T700XXU1BOE5 which has a lower change-list does not boot ) or newer
T705: XXU1BOE6 or newer
T800: XXU1BOE2 KXU1BOF2 or newer
T805: XXU1BOE3 or newer
CM SUPPORT
Read Post #12
"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
HOW TO BACKUP YOUR STOCK KERNEL BEFORE FLASHING SkyHigh KERNEL
Boot into TWRP Recovery
Select Backup
Select "[X] Boot" only (boot.img/kernel)
Select Storage > Micro SD (if external sdcard installed) > OK
Swipe to backup
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
BATTERY TIPS
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLTAGE OR FREQUENCY FROM DEFAULT !!
There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
The kernel defaults are balanced with a good mix of battery whilst keeping performance
Decrease screen brightness
Use dark wallpapers and app themes
Check your wakelocks with better battery stats or wakelock detector apps & use Greenify app to stop unwanted apps self starting and running in the background
Synapse:
- CPU GOV: governor = ondemand (tweaked for power efficient work-queues)
- CORTEX: PEQW = Enabled
- CPU FREQ: 200 > 1900 MHz (-25 mV for all 200 > 1900 MHz freqs - depending on asv_group)
- CPU MULTICORE: Hotplug CPU up load = Balance (with Hotplug CPU UP boost >0%)
- CPU MULTICORE: Hotplug CPU UP boost = 60 % (to 90%)
- CPU MULTICORE: CPU Multicore Power Saving = Aggressive
- GPU: Midgard Power policy control = coarse_demand
- GPU: Midgard Power policy threshold control = Battery (may induce some GUI sluggishness with 100 MHz min.)
- GPU: 100 > 480 MHz (-50 mV for all 100 > 480 MHz freqs - depending on asv_group) (Min 100 MHz may induce some GUI sluggishness)
- PowerSuspend Driver = Enable
- MEMORY: Dynamic FSync = Enable
- MEMORY: Dirty Page Writeback = Enable
- IO: RQ Affinity = Enable
PERFORMANCE TIPS
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLTAGE OR FREQUENCY FROM DEFAULT !!
Disable DVFS with [APP][Android 4.0+][DVFS Disabler] - Warmer device under heavy load, but within the safe CPU temp of 95 degC (NOTE: Xposed for Lollipop is still experimental, so results may vary)
Synapse:
- CPU FREQ: 500 > 2000 MHz (2100 not stable for some devices)
- CPU MULTICORE: Power Savings = Performance
- CPU GOV: use Interactve governor
- GPU: Midgard Power policy threshold profile = On-demand or Performance. (This will scale your GPU up/down faster at the expensive of battery life compared to Battery profile)
- GPU: GPU max freq = 533 MHz (more if your device is stable)
- MEMORY: UKSM = Enabled
- ADVANCED: LMK profile = Aggressive
LITTLE CORE CPU FREQUENCY
Real frequency is apparently double that reported by other apps
Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use stock ROM base that's confirmed working

CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
WHAT IS F2FS & HOW CAN IT BENEFIT
Info
Improved performance
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable TW DVFS with wanam xposed. You will need his xposed for Samsung Lollipop.
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
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)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

BACKUP & RESTORE
DO NOT restore profiles from different kernel version
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
Reboot after applying your new settings

thanks for your plans to include the Tab into your work. Really appreciated.
Just to ask (I am not sure if this is the right time to ask) if you can include some good sound system (Viper, Wolfson, etc).
Thanks in advance.

Just walked in the door after 2 days of international flights (jet lag big time), please give me some time.
I'm not sure if you realize, but I am the builder of previous SkyHigh kernels for Tab S KitKat, just haven't the time to build for LL until now
Intend to have most features from older SkyHigh KK builds. BTW, Viper is not a kernel feature ..........
But one step at a time
Good stuff been waiting for this. Sky high was always one of the better stable kernels.
Just one request though. Could you build an F2FS compatible one aswell or at least release your source code on your repo so I can build it myself.

I might take a look at some point. I have never tested it, but a 800/805 user did say had it working on KK with SkyHigh + recovery ..........
I just spent 2 hours trying to sort out a compile error, if only I'd checked the GPU code. It has changed in LL and now uses midgard sources :cyclops: Just tired and not thinking straight and cherry-picking without actually looking !!. Continue tomorrow

I read that and he was actually wrong. I could see how he thought it had worked, but the script he used would never have worked on any of our roms, it actually did nothing.
All that happened was that the partition that he formatted to f2fs automatically got formatted back to ext 4 upon first boot.
Your kernel didn't work with an f2fs partition as it needed some modifications to the actual source code to make it work.
It was the same story with iron kernel, but Tkkg managed to get it to work by pulling in some changes from Nvertigo's repo.
I managed to get it to boot after making the required modifications to the ramdisk.
Unfortunately the kernel had other issues which caused the tablet to freeze. This was seemingly caused by adding hotplugging to the kernel.
I was then looking for a good t805 lollipop source to build from until iron kernel was fixed.
Unfortunately your repo didn't have the lollipop kernel source, so just left it alone until I could be bothered again.
For touchwiz LP and CM12.1?
Great news!
Good to be able to OC LP Rom.

Only TW.
Firstly, no disrespect to those Devs, I just find CM boring visually and tacky. It's just my personal opinion, not a criticism of one's choice to build or use There is no "right" or "wrong". Secondly, I don't have time for it other than what I can/want to spare.
Editing OP.
Delete...... Good to see Skyhigh back! Was great in KitKat! Can't wait to see what's in for lollipop

Sure, no problem.
Hi, upintheair, glad to see you come back! a few days ago, I compiled a custom LL kernel, using your gpu hooks. LL kernel uses a different graphic driver, but the code are more or less the same, just modify the corresponding files in midgard then gpu hooks are going to work.! I planned to share my kernel source on github but now you are going to develop a more advanced one, it seems that I can stop doing this and wait for your kernel, once it was out, I will flash it to replace my own.

I woke up early this morning, (body is still in another time zone), and have Synapse up and running.
Have already implemented: CPU voltage control, GPU OC/UC, GPU voltage control, GPU clock & governor control for new sources (not yet committed to github). Could give screen shot, but busy testing before Son goes to school
Just have an issue to sort out (not sure if ROM or kernel yet) for some apps FC on boot. Might be to do with Selinux
Welcome back!! I am glad to see you making kernel for LL. I chose to stay on KitKat as I am getting way too good battery life from your kernel to switch. No lie, I get about a weeks worth of use before I have to charge it. Granted I am not a heavy use, average about 6 - 8 hours of total screen time, but it is truly a join to not have to charge each night. Previously the best I got was a day and half with the same use patterns. Again, welcome back and look forward to your LL kernel. This will now motivate me to upgrade. :good:
I'll probably release v1.0 for T700 & T705 today. Still a bit of work to do yet with Synapse.
T800 & T805 will be a while away yet as first beta reported failed to boot using same source. So I will build for my device first until I'm happy with it's progress, then take a look at 10.5" again.
EDIT: Changed my mind, I wish to continue instead of release. I don't want to hurry. Why stop when I'm on a roll

Introduction
In this thread you may find the stock CM kernel 3.4 for MM-6.0 rom (CM 13.0 and derivatives) which include unmerged CAF Patches for testing purposes.
Of course, your feedback, as always, are welcome and certainly valuable.
- When reporting bugs please mention which CM/Kernel version you're running. (About Phone -> kernel version [Should begin with [email protected]])
- Also make sure to mention which device you test it on: d802, d800 etc.
- If you notice improved behavior also be sure to write a review as well, this helps me in figuring out the exact improvements done by the patches.
Unsupported Roms:
- Resurrection Remix
- Blisspop
- Broken OS/Rom
What NOT to expect:
Don't expect this kernel to fix anything related to RIL (Invalid Number/Preferred network selection etc.) these are problems which reside in the LG binary/library blobs and not the kernel. Whenever the kernel fixes something major I'll make sure to mention it in this post. Builds get tested by me first so I'll try to make sure it doesn't brick your device.
What to expect:
- Currently it appears that there seems some improvement with screen rotation, it seems to fix the pixels showing on rotation bug [Please verify this yourself as well and report back]
- CM Team warned me about one of the patches which might cause your headset buttons not to function with this kernel [If you have a headset please test if it functions correctly with this kernel, make sure all the buttons work!]

Installation instructions
Back-up your current kernel so you can always go back
- Boot to Recovery
- Choose backup and untick System and Data (if you only want to backup kernel otherwise just leave it as it is)
- Swipe to Backup and you're done
Return to main menu by pressing the back button and proceed with installation steps below:
1) Download the preferred kernel zip file to sdcard or external sdcard
2) Reboot to recovery mode
3) Flash the kernel zip file
4) Reboot the system
Important: As long as you'll participate in testing when, updating CM OTA you'll have to reapply the kernel zip file. (CM OTA overwrites boot partition)!

Booted OK i think this fixed small pixels when phone is rotated. Anything to test?
Sent from my LG-D802 using Tapatalk
Just to add my own experience. I've been running the d800 20160111 kernel for many hours now and it has been very stable. I'm not sure what the small pixels problem was, but considering how many of the fixes are for the video subsystem, I wanted to mention that I've been successfully playing Badlands through parts of the day, quite successfully.
Except for the part where I can't make it through the game level without dying. That kinda sucks, but I'm working on it.

If you have a headset for you're phone please test if all the buttons work okay.
In this kernel there's a patch included in which CM-Team encountered problems with it in the past.
Other then that there's nothing specific to test atm. just run the kernel for a few days and report if you encounter any strange things or notice any improvements to the kernel which CM is shipping with their OTA.
I tested buttons in youtube app all working. I think kernel is a bit smoother. On balanced profile in battery settings phone achieved 51k in antutu.
Sent from my LG-D802 using Tapatalk
Currently I'm also benchmarking CM-13 build 12/01/2016 for D802 with Antutu and GFXBench.
It's very difficult to base any conclusions on these scores because it's very difficult to always have the phone in exactly the same condition as the previous test.
But I'll also run multiple tests with Antutu to check if there's a steady improvement or regression.
I think GFXBench will have most impact given the fact there are multiple vidc and mdss patches inside.
I'll report back with my findings after a few tests so anybody can compare their findings to mine.
Update 1:
After finishing extensive benchmarking in almost the same conditions (Airplane Mode), Balanced battery profile, reboot after each benchmark I come to the following conclusion:
There seems a small, almost neglect-able improvement in performance. Of course every improvement is good because that's what we're aiming for of course. Benchmarking results with patched kernel seem to be a little bit less jumpy in score though. At least stress testing through multiple runs doesn't result in any strange kernel behavior so that's nice to notice as well.
I'm not sure if this has any place here...
First off thanks @PsychoGame for this! We are well on our way to a great C13 experience!

Hello @jl10101,
I'm aware some people have problems with wifi losing it's signal while phone is in deep sleep.
On my phone (d802) in my case I don't encounter this issue to be honest so I'm not able to debug this myself.
My first focus is to get kernel up-to-date with latest msm8974 drop from CAF.
After this, if some patch didn't magically fix it already , I'll try to look into any known bugs.
Tried your kernel on Jan 12 build. The pixel problem is solved . I tested the headset buttons with Poweramp its working fine.

latsest RR didnt booted with this kenel
Bliss did not boot with this kernel either but aicp mm did
Hello @syrkles and @vrwmiaris1
I'm not familiar with RR or Bliss at all.
Are these Roms directly based/build from CM kernel and device source tree?
If not this kernel is not meant for the rom in question.
Also can you tell me which devices you have?
Nice to hear AICP MM is booting, I'm guessing this rom source is directly based of CM sourcetree
Greetings PsychoGame
Before using this kernel, i am facing some extreme lag from time to time even after clean install, but this kernel seems to solve this issue, great work!
Sent from my LG-D802 using Tapatalk
@PsychoGame
Both are based on cm. Probably some issues in their ramdisk
Hello @Lawlrus,
Thank you for your explanation, I'm not familiar with these roms but indeed if something in ramdisk is different from CM ramdisk indeed it's giving problems booting.
Good point and didn't think of it yet, al least I'll post it in the OP that RR and Bliss do not work with this kernel to make sure that's clear to everybody who wants to try the kernel.
Greetings PsychoGame
It seems that those change in your kernel will be included in the next nighty?

Hello @ansontyl96,
Indeed, the next nightly includes a big part of the changes included in this kernel.
I have used this kernel for over a week and so far haven't encountered any negative side effects.
Based on the fact the kernel had been downloaded multiple times for different device models (d800, d802, vs980 and l01f) but I haven't received much to nothing at all negative comments so we went ahead and merged it.
Next kernel beta release is in the pipeline at the moment and will probably be posted tomorrow.
Greetings PsychoGame

Cheers mate, I can't wait to test it as the kernal I am using now already solved many lag issues for some reasons,before this kernal i always face some extreme lag from time to time probably because of cpu, but just wanna ask will there be any chance that we can fix the speaker's low volume issues?
Anyway great jobs

Let's me see about that one, But that feature is available in GSI ROMs.
https://forum.xda-developers.com/project-treble/trebleenabled-device-development
Try RR or Havoc ROM.
I'm using stock with arter kernel. Gsi have too many bugs for me. I hope you can do it. Thanks.

well i (with friends) found out how to fix Bluetooth audio and there's no bug left if you are using latest phh gsi or pixel experience. (Expressluke broke his havoc on latest versions)
Couple of questions.
1. I see this is a zip, so do you have to already have the arter kernel installed with TWRP to install this?
2. If that is the case, can this then be installed over the arter kernel?
3. Will it keep TWRP?
Also, thanks for the development, Razer Phone 2 development is quite scarce.

1. You can directly flash this via Arters Kernel using TWRP..
2. This will overwrite your current kernel which is Arter's Kernel.
3. Yes.
As for the next version I'm already implementing new features from other devices like blue_schedutil, KLapse, and other more optimization and patches.. This might take 1-2 weeks.

Is incoming SMS working now? Is the fingerprint scanner reliable? Play Store device certification? Those three things have kept me from using any GSI I've tried.

Both always worked for me.
also fingerprint got fixed on 10
I've already KLapse, USB2 Fastcharge, KCal and other more goodies :" .. Hope you enjoy my next version of my Kernel.. Ofcourse F2FS is supported since my Kernel Source is from Arter's Kernel Source.

Fixed it sorry!! The kernel works well if it's flashed via TWRP... Here's the fix if it's flashed via fastboot.. Kindly download the img and flash it.
If there's any problem kindly provide kernel log.
But everything works well now.

Alright I'll look into it at a Kernel Level Perspective.. I'll be creating A module for that one. No promises yet but I'll add it to my To Do list.
Thank you for the time and effort .
Can SELinux be flipped to permissive on this kernel on GSI? With arter97's kernel SELinux cannot be changed to Permissive, though it might be due to GSI.
I need SELinux permissive so I can make use of Tincore for gamepad accessories like FeiZhiWee2T. Without SELinux permissive Tincore will not be able to see my controller.
EDIT: Just flashed and the answer is no. I think most likely both the kernel and GSI need to be able to support permissive in order to do so.
