JellyX Kernel 2.6.32.60 // 10.04

If you want to report something head over here and make a "new Issue".

I followed this community now about one year and i wanted to give something back.
Since we managed it to boot a custom kernel, i started reading into stuff and trying to learn how to make the most out of it.
The result so far is my little kernel, it's mainly based on Quarx's one but has some additional features:

  • Added more Governors (Smoothass, Brazilianwax, InteractiveX, SavagedZen, Scary, Superbad, Lagfree, MinMax)
  • Added more I/O-Schedulers (Anticipatory, Deadline, V(R), BFQ v2, ZEN)
  • zCache Support
  • Cleancache Support
  • XZ Kernel Compression
  • zRam with snappy compression
  • Undervolted: 300/24, 600/40, 800/46, 1000/54
  • Optional: Choose between CFS and BFS CPU Scheduler
  • CFS Autogrouping enabled
  • Tiny RCU
  • Updated CRC32, jHash
  • FSync Control by Ezekeel (Read more about this here!)
  • Proportional Rate Reduction for TCP
  • New and shiny Wifi drivers by Quarx
  • Dynamic page-writeback Control v1 by Blechdose
  • SLUB memory allocator (instead of SLAB)
  • Some more little changes
Click to expand...
Its mainly designed for Quarx's CM10-Rom, however if you tried another rom you can tell me the name and i add it to the compatibility list :)

You can find the downloads over here. There is one for CFS and one for BFS.

Installation:
  1. Download and put it on your SD
  2. Reboot into Recovery
  3. Make a Backup :)
  4. Wipe Caches
  5. Recommendation: Wipe Data (optional)
  6. Install my Kernel Flash at your own risk!

By the way, if you have useful patches or commits, send them to me, don't be shy :) Or provide me the source for a specific feature.

Something to read:



So far confirmed to be working with:
  • Quarx Rom 4.1.x (18.11, 28.11, 5.12, 22.12, 31.12, 10.01, 17.02, 24.03, 26.03)
  • SB 3.0, 3.1
  • PACMAN 18.0.0
  • CNA 3.6.6
Click to expand...
About the 3.0.x Kernel:

My 3.0 kernel shares the same advantages and disadvantages as Quarx one. However i started working on it in a very early stage.
So to keep it short, whats already working:
  • zCache
  • CleanCache
  • UKSM (instead of KSM)
  • FSync-Control
  • IO-Schedulers (BFQ, ZEN)
  • XZ Compression
  • Latest Linaro
  • "Ram optimizations"
I am working to get phone working (to help Quarx somehow..), but since many things changed related to this, this will be rather hard than simple... Help appreciated :D
Click to expand...


Troubleshooting;

If you encounter any problems, please post full information about your system (governers, overclocked, zRam enabled, cfs or bfs version, etc...) and if the same problem exists with Quarx Kernel or with a earlier kernel.
Furthermore run "dmesg" in terminal and post it or send me a pm :)
And don't worry if it's not working for you, try to play around with some settings.
All in all, if you want a better kernel, try to be much precisely as possible and what steps you did. It helps lot more, if you say more rather than less. :)


Thanks:
czechop, Quarx, Epsylon3, Kayant, franciscofranco, Skrilax_CZ, kabaldan, Ezekeel, the CM-Team and everyone else i forgot :)

03.04:
  • Updated modules in order to let the kernel work independent of ROM version
  • Because of module-update some random bugs got fixed (like cpu spy)
  • Wifi should be on the same stage as with a .9 Kernel

Read more about this here, should be also work with CM10.1 (not tested)

I repeat my thanks to you men. Working great on slim beam with scary governor. I'll test a little more, but it seems to have a very good life of battery. May be no recommended for games, because it work to lows frequencys almost all the time, but it scale so fast when CPU is needed. The others features enabled, are used by default or there's a way to enable them. Thanks so much...

The thanks button doesn't bite. Try it!

If there's something that I've never thought of seeing here on Defy Dev Forum, it was an thread about an custom kernel for it. :p

Keep up the good work, and if you need an guinea pig for testing, you can count on me! :good:

Guys! Morning to everybody!
Is it enough to install through cwm or have to install again the nightly and gapps?
Thx

@Blechd0se
You should include info if your kernel format E to EXT4 and which kernel does it.
Less experienced users might be warned about E: can't mount problems. Which sometimes* are not fixed by CWM - Tools - Format.

* when you have CMW ver. 5.0.6 for example.
