[KERNEL][AOSP][EXT4] Kang Bang! 7/12/2011 [BFS/CFS][OC/UV][BFQ]
Here we go guys, new version of my BFS AOSP kernel (sense to come)
Been working hard on this kernel for quite some time, and Birdman helped out drastically (even though he broke stuff )
Big thanks to: Birdman, Slayher, Captainkrtek, Imoseyon (for the 2.6.35 port), Jake Day, Pershoot, and plenty of others I can't remember right now.
Kanged workqueue 18.104.22.168 backport from Imoseyon
Kanged 3.0rc6 cpufreq/cpuidle backport from Imoseyon
Couple other adjustments
Added new CPU governor: LagFree. This new governor is based on conservative, and tweaked to lower the cpu frequency on suspend, and keep it over a minium value
during phone operation. This governor added some nice tweaks to be added to other governors, looking in to that.
Swap cache dropped more agressively via ck1 patch
More compiler optimizations
Decrease default dirty ratio via ck3 patch
Enable swaptoken only when swap is full via ck3 patch
Wifi voltage lowered
2.6.39 Conservative governor backported
Call Recording support added
2.6.39 bcm4329 (wifi) driver backported
Mecha: Add gan sound device.
Mecha: Allow varying of button backlight levels.
Mecha: Allow disabling of the back mic.
Mecha: Add gan sound device
Mecha: wifi: Improve BT-coex in A2DP mode
Added SmartAss back
Ondemand and interactive have sleep profiles again
Sound fix from birdman included
SLQB Memory Allocator re-added
Re-based to Ace kernel source, so I lost some of my changes for now (until i'm not so lazy and fix them)
There are a LOT of changes/additions.
Theres a new RCU boost, which is proving to be nice so far.
Changed the memory allocator to SLUB until I get SLQB ported in
As of right now, theres no auto sleep profile in ondemand/interactive. Both of these governors still need adjustments.
The clock frequencies are the default CM frequencies. Their table is populated correctly, and currently, I'm adding frequencies back in one at a time to make sure it will boot. This will take a while... bare with me guys
Lowered RR_Interval to 6 to increase latency. Might drop it to 4
Neon and VFP optimizations
OnDemand governor Threshold adjustments
CONFIG_HZ=300 instead of 100
Add Tiny Preempt RCU
RCU Boost Prio set to 50, Delay set to 300 (still playing with these)
Sound tweaks credit to CodeAurora/Birdman
GPU Memory allocation raised
Numerous fixes from CM kernel source
Reverted the GPU/Camera memory allocation adjustment, as it screwed up the camera.
Reverted to my old config file, as the extra slim one broke certain apps
Full wifi/settings/MMS/etc. fix credit to beavis9k!!
Added V/R I/O Scheduler (still using BFQ as default for now)
BT Audio volume raised (Credit to Slayher)
Prevent memory leak on hotplug (thx Pershoot)
GPU/Camera memory allocations raised
Cleaned up my defconfig even more. This kernel is tiny, tinier than ever before. The actual kernel zImage is 1.9mb as opposed to the 2.2 it was before. This will allow a performance increase, as there is less the kernel is trying to crank out.
Initial release, 0.3:
Feature packed for the first release.
22.214.171.124 (latest upstream linux kernel)
System/Data/Cache mounted EXT4
Numerous EXT4 file system tweaks
Overclock up to 1.8 Ghz
Undervolted for battery life/stability
BFS v404 (HUGE performance increase from the v3xx BFS series)
SLQB Memory Allocator
BFQ v2rc1 I/O Scheduler (much nicer than the original BFQ)
Kernel speed defaulted to 1024, stock tbolt speed
OnDemand governor backported from 2.6.39, with sleep/wake code (kanged from Imoseyon's OnDemandX, thanks Imoseyon!)
Wifi driver updated to latest AOSP driver
AOSP-style BT driver (kanged from Slayher's kernel source, thanks Slayher!)
MULTIPLE fixes pulled in from CyanogenMod MSM7x30 kernel source (time compensation, ashmem flush, wifi n support, CPU-supported unaligned access, compensation for rounding on odd-frequency clocksources, etc.)
Interactive governor with sleep/wake code (kanged from interactiveX, thanks Imoseyon!)
Numerous BFS tweaks for better performance, and better support for android.
SD Card read-ahead buffer increased
FS read-ahead buffer increased
Some other things I probably can't remember right now (I should take better notes, I'll add more as I remember)
Whew. Pretty hefty initial release.
Secondly, I comply with GPL. Here is my source code. Feel free to kang away, just credit me, at least in your source if not anywhere else http://bit.ly/lSXnZx
