[KERNEL][SENSE 9/14/11 2.9.0][AOSP 9/14/11 2.9.0] nerozehl's dreamKernel [BFS][BFQ]
- Thread starter nerozehl
- Start date
Cool gonna try this out once I drain this battery and slap a fresh one in. I tried this yesterday and got a lot of lag with lock screen and just basic functions. Also I would reboot and the battery would read like 10% higher and seemed to drain quick don't know if its just read the battery wrong or what. Any ideas and what to do I will try because when it ran smooth it was awesome thanks.

After I installed 2.0.1 GB Sense, logcat stopped functioning. Whether I call it from the shell or straight from ADB, I get:
I think I found the source of the problem. As a performance tweak, nerozehl killed the logging daemon in /etc/init.d. Reflashing imoseyon's kernel does not restore the log. (It doesn't delete the file inexplicably named "99imoseyon" that isn't present in imoseyon's kernel.)
To restore it (like I want), I think this should work:
If you have trouble getting that to work, you can also remount /system R/W in Root Explorer, edit /etc/init.d/99imoseyon to put a # at the beginning of the fourth line, save and exit, then remove execute permissions on the backup file it created!

Lol, beat me to it. I forgot to mention that before. Logging, like camera debug, is one of those speed versus ability trades.

I don't know exactly what it is but my phone is very unstable with this kernel.

Could you be more specific? What kernel version, AOSP or Sense, what ROM, what's happening, what do you have your voltages/governor set at, have you enabled logcat to capture the instability.
Your statement doesn't tell me anything, and I can't help you without information.

Sorry didn't think I would get a response as I didn't a few posts back no I didn't enable logcat my laptop took a dumb so not much good I can do with that anyways. I'm using sense 2.0.1 although I have had the same issue on 2.0. I had the issues from beginning just in safemode on ran st script to pick governor. I switched to batterysaver to see if switch voltages would do anything. Didnt change anything. Basically everything lags. Pulling ring on lockscreen the screen unlocking choosing an app to be more specific I would choose an app remove my finger then it would highlight and then open. Almost like its underclocked at 245 even had tapatalk lag to the point of bringing up a force close.

Weird... Which ROM? I would assume you tried reflashing it??

I'm on bamf preview4 and I actually didn't try reflashing it. I will try right now.

Not to much better..sorry once my laptop is up a going I'll try to get a logcat.

Just flashed this kernel on Gingeritis 1.0 beta 9. It runs great, I have it set at undervolted Max at 1.92, then I disabled the governor settings and I'm running SetCPU profiles. Very nice work, I am enjoying this kernel very much.
Edit* I'm running 2.0.1 beta

I've been running this for the last couple of days and all I can say is outstanding. Everything seems to be working great. Haven't had any issues and battery and performance is top notch. Thanks nerozehl, imoseyon, and twistedumbrella for this compilation of a great kernel

+1
I'm running this + Gingeritis IX and not a single reboot, fantastic speed overall, & battery life is outstanding. Exceptional effort by all members involved. THIS is the kernel the phone shoulda shipped with

would it be possible to create a flashable zip to add logcat functionality back in for those of us that want it? i NEED logcat to enable Chainfire's live dmesg/logcat boot animations to work. a flashable zip (instead of a manual fix) would allow easy fixing after every new kernel update.

Edit: Installs a menu system that is run in terminal using "customtweak.sh" and allows choosing what tweaks are installed. The update defaults to all tweaks, and the script allows disabling them individually.
Previous: This is just the script file with log disable commented out for those finding the manual process strenuous. My next update will just build the file through a menu.

INTRODUCTION
This kernel is a developmental fork of the CM7/AOSP and Sense kernel tree built by Imoseyon (leankernel). With his permission, I have started working on an alternative kernel that offers some extra functionality.
The goal of this project is to add things to the kernel that aren't, well, necessarily lean. As development progresses, I intend to keep to the spirit of Imoseyon's work (by being careful not to make this too fat), and any major fixes or changes to code that occurs in his source tree will be ported to this kernel.
ALREADY COOKED IN BY IMOSEYON
Since most of you already know of Imoseyon's work (if you don't, see the link to his thread above), and what his kernel is about, I won't go over all the minutiae from his kernel's development, but I will highlight:
- Linux Kernel v2.6.35.13 with back-ported code nearly identical to 2.6.39.
- speedtweak.sh (on-the-fly frequency/voltage modification).
- interactiveX, ondemandX, and smartass governors that are highly tweaked.
- ramdisk enhancements (file system speed-up, init.d)
SENSE CHANGELOG - NEROZEHL'S ADDITIONS
version 2.9.0
- Fix WiFi issues.
- TinyRCU is now used.
- Tweaks to minfree.
- Filesystems mounted as ext4.
- Bugfixes. No more boot issues!
- Latest Charging code from Imoseyon.
- Wireless charging seems to work
- Another try at call recording...
- Charging and over-clocking modifications ported from Imoseyon's kernel.
- Call Recorder has been added. It is reported to be working for someone when receiving calls. I'm tracking the issue down, but the code is there. YMMV.
- Latest charging and ramdisk tweaks from Imoseyon's 3.3.6
- Bluetooth patched up! (thanks Imoseyon!)
- After much anticipation, a new version!
- Kernel base changed to Imoseyon's latest 3.x source (as of 6/22/11), including charging and camcorder fixes!
- Call recording support coming in the next version!

- Added in some of Imoseyon's tweaks for performance. Thanks!
- All the usual refinements from my AOSP kernel, except for Sense! This kernel source has been pulled from Imoseyon's latest work (DesireHD kernel)
- Brain **** Scheduler (BFS) task scheduler

WARNING
As a general disclaimer, I do not accept responsibility for what may result from you flashing something I post. While I take every precaution and thoroughly test before I release, I cannot be to blame for catastrophic failure.

GEE PEE ELL (GPL) AND USAGE
My source-tree can be found here. I have permission from Imoseyon to use his source for this kernel. In turn, I've given permission for folks to use my kernel in their ROMs as well. Consequently, if you use this kernel in your ROM, please credit both Imoseyon and myself for the work, and--while not required--a heads up if you're using it in a ROM would be appreciated. If you intend to use my source-tree for your own kernel, then you must get permission from both Imoseyon and myself.
ADDITIONAL
I sincerely hope you find this kernel to your liking. If you find any bugs, or if you have questions or concerns, please feel free to let me know. Likewise, if there is a feature you would like to see added to this kernel, I will be happy to look into it.
