Cleancache provides a place where the kernel can put pages which it can afford to lose, but which it would like to keep around if possible. A classic example is file-backed pages which are clean, so they can be recovered from disk if need be. The kernel can drop such pages with no data loss, but things will get slower if the page is needed in the near future and must be read back from disk. Like Cleancache, Frontswap can play tricks with the stored pages to stretch its memory resources. The real purpose behind this mechanism, though, appears to be to enable a hypervisor to respond quickly to memory usage spikes in virtualized guests. Dan put it this way:
Frontswap serves nicely as an emergency safety valve when a guest has given up (too) much of its memory via ballooning but unexpectedly has an urgent need that can't be serviced quickly enough by the balloon driver.
ZRAM (aka CompCache aka RAMZSwap)
ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.
Joe's RCU (Optimized for Small SMP systems)
Joe Korty has created an RCU for small SMP systems (> 32 cores). His approach is to isolate all the Garbage Collection (GC, a slow time consuming but necessary processing) to a single core, thus allowing other cores to ONLY work on real required processing. This will allow the additional cores to complete their assigned tasks as fast as possible (not bogged down by GC) then immediately go back to a suspended state (saving battery).
Fast No Hz RCU (Optimized for SMP operations)
Fast NoHz is an optimized version of the traditional Tree RCU. Many new kernels are using the Tickless NoHz design. This RCU is tailored and designed to work with the new NoHz kernel system.
SmartAssV2 Governor (Balanced)
This governor has a built-in "profile" similar to SetCPU, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).
Interactive Governor (Performance)
This governor is designed to put more priority to User Interface (UI aka Apps) tasks, therefore appears more responsive then the traditional OnDemand governor. So if you want the smoothest UI interaction, this governor is for you...
Brain F*ck Scheduler - (BFS)
This scheduler is designed to be simple and speedy tailor specifically for user interface type systems such as desktop/smart phone devices where user interaction is MORE important than serving 1 million web requests (CFS, the default scheduler) at the same time (think of nimble desktop workstations vs large corporate servers).
SLQB - (SLAB allocator with Queue)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate). Not all kernels are using SLQB including CM7 main line...
Fair Budget Queue (BFQ I/O scheduler)
This I/O scheduler is an improvement on top of Completely Fair Queue (CFQ). CFQ is fair in terms of time but not in terms of throughput / bandwidth, so BFQ make sure that both time and throughput / bandwidth are balanced across all requests.

Dead Horse Reloaded
Kernel- New Dead Horse Reloaded- 2.2 & 2.2.1 4/24 by Eugene added 05/01/12
New for Advance Users Dead Horse Reloaded:
To Flash, Download neldar zImage Flash Utility from the Market & place the zimage in the folder the App makes..
Based on edify ( Old amend update script will no longer work ) Time to Learn People!!!
Fully Based Off CwM 3.X ( With edits by me to be 100% Functional on the Vibrant )
No SD wipe issues
Formats to a true ext4 partition regardless of movinand size without errors
Default Ext4 /system /data /dbdata /cache mounts & Format with RFS Mount Support for First time User's
To Restore RFS you will need to ODIN ( Next Build will feature RFS formatting support ) or place a Voodoo zImage on /sdcard/zImage & Flash using the in recovery zImage Utility
100% Working Internal & External Mount To PC
100% Working Internal & External Mounts for flashing .zip from SD
Update zImage straight from recovery ( Must mount /sdcard first! ( This is to keep people from flashing by mistake ) Place zImage on external sd = /sdcard/zImage
Primary /sdcard is the external to avoid soft-brick issue caused by formatting with ext ( /sd-ext ) & swap Support. Swap however is not needed!
Issues & Fixes to Come:
Factory wipe from Android OS not working, Wipe / Factory reset from Recovery! ( Issue is Fixed when Flashing GCR3-Update6 )
Fix OS Wipe issue ( Issue is Fixed when Flashing GCR3-Update6 )
Implement RFS Formatting for those that wish to revert to stock /system /dbdata /data /cache file system
Unverified if flashing is 100% safe over voodoo, but shouldn't be an issue.
Voltage Settings:
{1200000, 1275, 1100, 1} Need SetCPU or any other OC Program to use!!!!
As a learning experience, I decided to give kernel developing a try. Tigers Blood is the result. I wanted to make a kernel with some OC/UV capabilities, but yet stable enough for the everyday user. I took a minimalistic approach and by default, the kernel is at stock clocks and voltages and will clock to 1.2 Ghz.
Includes :
Voodoo Sound v7
Voodoo Color
Vodoo Lagfix with modified Clockwork Recovery
BLN (Neldar's free version of "BLN Control" is included - Please donate to Neldar or buy the full version in the Market if you like his work - Full version allows blinking backlights)
CIFS ("Mount Manager" in the Market will get your network drives mounted)
TinyRCU
339 MB Ram Hack
OC/UV capable to 1.2 Ghz (Stock clock and voltages out of the box)
The kind of kernel published here are only stock kernels, which means the exact same code build by Samsung for Vibrant phones.
Of course, there's a difference: Voodoo lagfix 5 stable has been injected in them, with its extensions and also ClockWorkMod recovery as default recovery.
Voodoo lagfix converts /system, /cache, /dbdata and /data to Ext4 with optimized parameters for speed but also guaranteeing data integrity.
Also, it configures the write behavior of Linux to prevent lag from happening, plus apply some memory management providing a better balance than stock settings.
Also supported: custom boot animation, init.d scripts and an improved adb shell (new!)
This kernel also installs the su binary for your convenience. Only activated once you download Superuser App from market. If you don't want to "root" your phone, skip this part.
How do choose the version?
The best version is the closest to the one of the ROM / system you run.
If you use a custom ROM instead of an official Samsung one, ask your ROM dealer which one is closer
update.zip you can flash with ClockWorkMod recovery (not 2e or 3e)
JK2+Voodoo
JK6+Voodoo
JL1+Voodoo
JL4+Voodoo
JL5+Voodoo
KA5+Voodoo
KA6+Voodoo
KA7+Voodoo
KB1+Voodoo
.tar you can flash with Odin or SGS Kernel Flasher
Sleep fix not in, treat it like a stock kernel for now until notified (Do not use profiles that exclude 800mhz)
Only flash this kernel from a "red recovery", do not flash it coming from any ULF kernel, flash a stock+voodoo kernel in-between, then flash this kernel.
Not sure what these other kernels do, but I'm tired of hearing my kernel breaks anything due to THEIR incompatabilities.
Included:
Voodoo Sound v4 (Thanks supercurio)
Voodoo Lagfix (Thanks supercurio)
Voodoo Color (Thanks supercurio)
BLN included (Thanks neldar)
Based on T959 froyo source.
Safeboot to 1GHz for those phones that don't like OC (But 1.4 can be used with setcpu)
TUN (Tunneling/VPN support)
CIFS (Samba support)
JFS (Advanced users only, no automated use of this FS)
DoW14-T959 359MB RAM version -> No HD Video
DoW14-T959-HD v1.4 344MB RAM version -> HD Cam working | md5sum: 743ee5f1023a571260d32bd4c0fcc7f3
Best steps:
Get off your ULF kernel first, flash Stock + Voodoo in-between
You inform yourself what "OC" is and what to expect
Install Neldar's "SGS Kernel Flasher" before flashing ANY kernel.
LIPPOL94's kernel cleaning script integrated into flash package
SetCPU's 400/100 screen off profile safe to use, but not recommended.
NOTES:
The cleaning script is integrated into the flash package, so it will clean before the kernel actually flashes, once its done and you reboot, it will take a little while longer to reboot since the dalvik-cache is wiped.
It is safe to use a screen off profile with 400/100 setting, but i do not recommend it.
The splash screen is the same skull from my froyo kernel, but it has "CM" on it. If you dont like skulls or my splash in general, plz use another kernel. And NO, i won't change or make another version of it, so plz don't ask.
My beta tester, Skitz, has reported low quad scores with this. If you are a person concerned with benchmark scores, then this isnt for you. Quads don't make the kernel, the performance does.
Running OMFGB so i know this will work on that and regular CM7, i hear that CM7 kernels also work on MIUI, but i have not personally tested it on it.
CWM 2.5 (the regular red Voodoo recovery we all have come love)
339MB of memory
Smartass and Interactive CPU governors (Conservative still default at boot)
Volume keys mapped to i9000 so no changes needed in the ROM and the keys work correctly in recovery
OC with safe boot to 1ghz use SetCPU to set clock speed
GPS init.rc
Proper headphone jack routing for T959
USB dock audio should be properly routed as well
Based on xcaliberinhand's reoriented i897 JVB Kernel and supercurio's voodoo lagfix initramfs
Notes * Make sure to match the kernel version to the ROM version. You want to use the JVB kernel on JVB based ROMs and the JVH kernel on JVH based ROMs.
Bullet GB JVP 1.2ghz
Bullet GB JVP 1.42ghz
Bullet GB JVP 1.54ghz - This one is for you speed freaks with special phones.
Changes in LED handling. (Possibly fixes most remaining issues.)
You need this to control the LEDs CMParts see here to install properly (Doesn't install like a regular apk, the reason is its not really an app, it's part of CM7 with modified setting panel for LEDs)
LED on on resume has been disabled for now (keyboard woes - I think.)
Touch key: Enforce recovery routine during r/w failures (Fixes: Touch keys flash and stay off when missing a call - Possibly other weird situations.)
LED stay on when screen off as long as notifications are not deleted. (Due to popular request.)
Fixed liblight for quiet hours/LED issue.
Touch keys light up at resume for a short time. (Like Samsung ROMs)
LED notification respects CyanogenMod's 'Quiet hours' (Settings -> Cyanogen -> Sound -> Quiet hours) Setting LEDs to dim during quiet hours will disable led notifcations during those hours (So it's like BLN schedule except its using the CM feature.) - Thanks for that suggestion.
Fixed keys light time out. (I was being dumb with calls during interrupts, sorry.)
DELETE ALL VOLTAGE CONTROL SETTINGS, AND REMOVE BOOT SETTINGS FROM CM SETTINGS AND VOLTAGE CONTROL AND DISABLE SETCPU PROFILES BEFORE FLASHING THE LATEST UPDATE. THIS GOES FOR ALL UPDATES, INCLUDING UPDATING CM.
This is a CM7 based kernel with a 1.6 Ghz overclock, Voodoo sound and color fixes, uv support, and BLN. See the changelog for all the updates and features.
Informations (THESE CHANGE ON A REGULAR BASIS):
Max clock is set to 1GHz on the first boot, set the max clock in CM settings or voltage control or setCPU.
I cannot possibly stress this enough. IF YOU EXPERIENCE BUGS WHILE ON THIS KERNEL, POST HERE. Do NOT submit bug reports to the CM team, until you have flashed back to stock CM, and can verify the bug exists there too.
Use Xan's UV app to undervolt.It's in that market, search "Voltage Control".
Want to go back to stock? First, if there's any particular reason, please let me know. I love to feedback, good or bad. Then, just flash the latest official update.

Alt Source & Downloads Here
Added audio dock support
Made revisions to smartass2
Voice audio through dock
Fixed BLN
Adjusted wifi for stability
OC to 1500 (Many devices will not run this high, but it's there for the adventurous. apps could close unexpectadly and your phone may freeze and rebbot. Be sure to uncheck set on boot in NSTools before trying. Use at own risk)
"Thus it would be nice to have some way for the user to individually adjust the bus speed to match the overclocking capabilities of their device. Unfortunately with TEUV the bus speed has to be defined on compilation time thus the only way would be to release different versions with different bus speeds which, frankly, would be a pain in the ass. So I implemented a way to change the bus speed on-the-fly while the device is running. In contrast to TEUV not only the bus speed for the maximum frequency but for all states is increased by the same percentage (might change this later, especially for the minimum state)."
Voodoo Color ( By Default this setting is Used, Once I have source posted you can compile without & using the color tuning that is built-in on Vibrant Passion Rom )
BLN ( Working as well on missed calls )
BLD ( Due to the Codec I Kanged to make BLN works, I also had to include this as well to Turn Off back light buttons like the Nexus S. the NS is the Kanged Codec here ).
