[KERNEL][ALL ROMS][SEP 14] Glitch for Flo/Deb - r574

Tk-Glitch · Sep 19, 2013

These kernels are provided as-is without warranty. I'm not responsible for any problem you may encounter with your phone or tablet or if your cat suddenly dies.
Although, don't expect support even if I will eventually help because I love cats.

Overview & features :

"With great power comes great responsibility". Don't go crazy with overclocking, only the best devices will be able to get 2.3 GHz stable or even bootable, though heat will be your main issue.

- Based on Google AOSP 3.4.0 and LineageOS's kernel sources for MSM devices

- CPU OC up to 2.3Ghz with OV/UV support / minimum frequency down to 81 MHz (configurable)
- L2/bus speed OC up to 1.49GHz / 4.8GBPS
- GPU OC up to 627 MHz with OV/UV support

- CPU governors : Faux's intellidemand, interactive, ondemand, smartmax, intelliactive, conservative, elementalx
- I/O schedulers: noop, deadline, cfq, fiops, sio, BFQ, zen

- Kernel based intelli-thermal driver by Faux123
- Kernel based msm hotplug driver by Fluxi

- tni.andro's battery life extender support
- Magnetic on/off setting
- USB fast charge support
- USB OTG charge hack support by flar2

- FauxSound support
- LineageOS's PCC color tweaking
- Fsync switch on/off
- Touchscreen patches by Showp1984
- Touchscreen wake/sleep gestures by flar2

- Kali Pwn Pad experimental support
- Optimized algorithms and libraries
- Various performance and power saving tweaks
- NTFS, NFS and exFAT support
- F2FS support up to all-F2FS with automatic ramdisk patching at flash time (reflash if you change partition format !)
- Kexec-hardboot support for Multirom compatibility

- Full package comes with Aroma installer to set core features at flash time (L2 OC level, CPU OC, etc.)
- Pure package will restore Aroma settings backup if present, or else will offer you a balanced preset for day to day usage

- Custom Synapse support with various settings and core features tweaks
- Compiled with Linaro 6.1.3 toolchain with various optimizations
- SELinux Permissive patch (Disabled by default, can be enabled in Aroma)

- Wifi firmware overrider to fix wifi on 4.4.3 & lower or on roms using old wifi firmware (up to r226 - Kitkat only)

CHANGELOGS IN #2 POST

You can tweak multiple options of this kernel with TricksterMod, FauxClock, Kernel Adiutor, Synapse(r500 and up, definitely recommended to get the most available options) or similar apps. (They are all available on the PlayStore)

Note to MultiROM users : don't use the kernel sharing feature. Flash the kernel on each rom instead. Also, it may take more time booting on secondary roms when using F2FS. Don't worry and wait for a bit

Downloads (all kernels are compatible with both flo and deb)

Mirror + older builds : Mediafire

FAQ :

What are the differences between "Full" and "Pure" builds ?
The "Full" builds are using Aroma Installer so you can tweak various options at flash time. At the end of the process, a file containing your settings will be created (/sdcard/glitch-settings.conf). The "full" builds are also able to restore your settings from Aroma after a rom flash or wipe for example.
On the other hand, "Pure" builds aren't coming with Aroma and will try to restore your settings from your SDcard, or use a default profile if none is found. Both Full and Pure builds are coming with a custom Synapse support to let you tweak all the core options on the fly once booted.
If you flash a "Pure" build without a profile, the default preset will be applied. It's been tweaked for a good balance between performance, power consumption, stability and functionality for day to day usage. The default settings applied are as follow :
- 1.7GHz max CPU freq (from 1.5GHz stock) / 1GHz max CPU freq when the screen is off / "Balanced" L2 OC
- msm_hotplug driver in place of msm_mpdecision
- 450MHz max GPU freq (inline with other Snapdragon 600 devices - from 400MHz stock)
- Safe CPU and GPU undervolting for lower heat and power consumption
- Deadline I/O sched / Interactive CPU governor
- Doubletap to wake and fastcharge enabled (Doubletap to wake will slowly drain power during suspend, so disable it if not used)
- Everything else is kept stock

What do I have to do to use F2FS on one (or more) of my partitions ?
First, BACKUP your data if needed, especially if you're planning to use F2FS on DATA partition, as changing filesystem will wipe the partition. Change partition formats as needed in your recovery. It is NOT recommended to convert system partition as F2FS as it'll be slower than EXT4 to begin with (as the partition is mostly read only) and will alter compatibility with many roms (especially CM/LineageOS based). The last thing to do is to flash any Glitch kernel with a revision number past r150. You can restore your settings from SDcard if any, the install process will detect the partitions and modify the ramdisk accordingly so you can finally boot and use your fresh FS.

What L2/cache OC setting should I use ?
This setting will overclock bus speed and RAM so it's a bit delicate to tweak, yet it can give a nice "free" global performance boost. A simple test to check for stability is to run the camera app 3 or 4 times in a row while waiting for 10 seconds between each launch. If your device freezes, it's unstable ! It's also the only setting you can't change on the fly once booted, either from Synapse or sysfs, and requiring a reflash (using Aroma or changing the value in /sdcard/glitch-settings.conf).
Let me give you some details about the available settings so you can choose wisely :

Stock (1.13GHz-4.26GBps) is the regular, out of the box, non OC setting.
Improved (1.19GHz-4.26GBps) is the same as "ElementalX" setting in Flar2's kernel.
Balanced (1.22GHz-4.66GBps) is the same as "Ultra" setting in Flar2's kernel.
Fast (1.35GHz-4.66GBps) is a nice jump over "Balanced", yet stable for most devices. A kind of sweet spot.
Extreme (1.43GHz-4.80GBps) is were most users will start to get issues. Provides a great boost if stable.
Glitchy (1.49GHz-4.80GBps) pushes your hardware to the limits. Will be unstable for most devices.

Thanks to everyone helping me to debug and find new useful things to integrate !

Without all of you, this kernel wouldn't be !

Looks like a nice kernel that will really show what this device can do

Thanks.

That's what I'm trying to make. And I *think* (may be wrong though) I'm the only one yet using a fully working GPU OC implementation on flo kernel. It's an adaptation of Galaxy S IV's (i9505) GPU OC code from Team Hydra.
It seems 627 MHz is around the max possible with stock voltage, probably even 600 MHz for many. I'll see what it can do with a bit more juice.

Other things to do : add more frequency steps for the CPU, lock the default freq, and make the L2/bus speed configurable.

After that I think we'll be able to push the thing to the limits if we want to.

Thanks for your hard work I'm going to try it on pacman ROM I'll let you know how it goes

I wanna show u my settings, I use trickster, so sound and faux kernel app to get the results I need was going to show you pictures but all the sudden XDA premium has no picture button I'm a little lost their. Touch responses phenomenal and just like faux kernel the sound is this did really well I can finally listened stock sound sucks on this product even know what has supposedly way better speakers, thanks to people like you I can actually hear the videos I watch without headphones now. Thank you very much I've been using it for about 5 minutes swimming around on everything and everything smooth as hell

The problem exists on the free app as well ^^
Try scrolling up and down away from the images and back on them, it'll eventually show up at some point.

thunderger · Sep 19, 2013

Thanks for your work. I'll give this kernel a try.

Coming from N4 motley kernel I'll love to use init.d scripts to set up color "calibration", sleep states, etc. What do you think about implementing / documenting such features for your kernel?

Otherwise, let me see if I need something. Hm, what about USB OTG and ntfs/f2fs support?

Tk-Glitch · Sep 19, 2013

USB OTG is working out of the box. NTFS/F2FS support isn't. I'll look into adding them =)

Your idea is nice, I'll think about it.

Thanks =)

cyberprodigy · Sep 19, 2013

Do you plan on adding Faux's color mod? I will give this kernel a shot and report back.

When there will be some source, yeah why not =)

I am running the kernel right now. All I can say is "wow".

You did a fantastic job cherry-picking the best features from various kernels. I notice a slight increase in smoothness compared to Faux's kernel plus D2W and all the other great features you added so I think this may be my new main kernel.

I will use it over the next few days and report any issues I find and how the stability is. Thanks a lot for your work.

Edit: Also, I am running CleanROM and everything seems fine.

Tk-Glitch · Sep 19, 2013

Thank you, so it may work with any rom then ! Good to know CM didn't break too much stuff leaving AOSP base.

L-ViZ · Sep 19, 2013

sleep to wake, doubletap to wake disabled by default? don´t need it xD

need a fast stable kernel and especially want to disable fsynch. if u run a stable rom it justs takes useless power xD

i´m pretty new to the nexus7 like the most of us . is that kernel stable?

atm i´m using faux´s, also used franco. i dunno, but on franco´s i couldnt change gpu govenor and the 3dmark benchmark was about 3000points, stock is about 6000-7000. pretty strange.

i am a pretty minimalistic user, want best batterylife/performance ratio. only using psx, best rom for me

i think i´ll try that kernel

edit: what does "Snake Charmer" do?

edit2: read s2w stuff enabled by default, can it be disabled via trickster?

thunderger · Sep 19, 2013

My N7 is running great with your kernel. Let's see what about perfomance and stability in two or three days. After checking and playing with trickster I miss a kind of dynamic fsync and a color calibration interface - compared to N4 m+ (motley) kernel.

Perhaps you can implement some upstream changes / patches directly from CAF or newer kernels.

It would be nice if you post some information about L2 speed hack, etc. So that everyone can see what this hacks do.

Which file are we supposed to use, they are all dated 20130919. I'm guessing the. 904.

Year/Month/Day/time

dunno if latest point is time in this case when you compare it to upload date. but yes it seems to be latest. upload time and build date can be different, so i think it´s the time.

Probably when it was compiled.

Just a heads up for those who want to disable swipe2wake or doubletap2wake, you can turn them off with the Trickster app but I did not find a setting in the FauxClock app.
