RedPill Kernel Features | RedPill Kernel Changelog | RedPill Kernel FAAAQ​
"This is your last chance. After this, there is no turning back. You take the blue pill - the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill- you stay in Wonderland and I show you how deep the rabbit-hole goes." - Morpheus, The Matrix (Copyright belongs to the Wachowski Brothers... Larry and Andy)Features

Set Clockspeed at 1.2Ghz at Boot time to ensure all critical tasks have enough power to perform them while the governors/maxfreq isn't set yet. (Thanks to Imoseyon for this hack)
CPU Features
CPU and GPU OC/UV thanks to netarchy/Hacre
CPU Governors Included:
Final Clean up of CPU Governors available for simplicity. (all Governors are tweaked for the best possible balance of battery and performance with a slight lean towards performance) With this focus on simplicity stated earlier, the only governors available are the following:
sleepy (ondemand based cpu governor with minor edits by pongster) loves to sleep and idle at the lowest set frequency, hence the name change from "solo" to "sleepy". Its closer to ondemandx in terms of performance. This can be tweaked and tuned using init.d scripts as well.
hyper (ondemand + suspend freq setting ability with minor edits by pongster) This was formerly the original kenobi which I renamed to hyper as others may not get the Star Wars Reference. It gives a good balance between battery life and performance. Its closer to ondemand in terms of performance. also tunable using init.d scripts.
conservative (good battery savings by default due to its slow ramp up and ramp down but tunable for performance) defaults are slightly tweaked for better performance than default conservative.
ondemand (old reliable thats been tweaked by arighi to support deep_sleep and fast_start) these features try to detect if the CPU is coming from a deep sleep and is more likely to sleep again and thus limits its frequency to the lowest possible that can handle the operations needed. fast_start checks if the CPU needs more "ooomph" and jumps to the highest frequency faster to enable it to complete the operation the system needs to complete. (like during boot-up)
3rd Party Kernel Apps Support
CWM Manager 3.0 (It works well for me. Its a useful app by Chainfire that extends the features of the current recovery. No need to reinvent the wheel, so to speak)
Voodoo Louder by supercurio
Voodoo Display (for future supercurio app)
2nd Core by Tegrak
Touch Move by Tegrak
SetCPU by michaelhuang
Voltage Control by xan
Filesystem Features (loaded by default to prevent the load insmodding at boot will cause, however minor)
CIFS
FUSE
NTFS
Experimental NTFS automount for OTG devices (you'll have to do a little more work to enable sdcard as ntfs) (Thanks to gokhan for the hotplug script as base.) This script uses the native NTFS RW support available in t he kernel instead of ntfs-3g
Ext4 Tweaks from 3.x.x branch:
[PATCH] ext4: fix ext4_end_io_dio() racing against fsync() from https://lkml.org/lkml/2011/12/16/311
*Reported-by: Kent Overstreet <[email protected]>
*Signed-off-by: "Theodore Ts'o" <[email protected]>
[PATCH] ext4: avoid hangs in ext4_da_should_update_i_disksize() from https://lkml.org/lkml/2011/12/16/344
*Signed-off-by: Andrea Arcangeli <[email protected]>
*Signed-off-by: "Theodore Ts'o" <[email protected]>
I/O Schedulers
SIO (2012 0.2 version)
deadline (tweaked for Flash)
noop
V(R)
Performance Patches
Mike Galbraith's Ultimate CFS Performance Patch (CFS Autogroup)<[email protected]> as ported by faux123 <[email protected]> for 2.6.35 kernels. I (sarcastillo <[email protected]>) additionally edited some things in sched.c to make it compile properly for 2.6.35.14 Samsung Sourced kernels*More info on this here: https://lkml.org/lkml/2010/11/20/91
Added the CGroup Patch:*Added [PATCH] cgroup: Provides a way of tasks grouping by timer slack value by Kirill A. Shutemov <[email protected]> Based on patch by Jacob Pan. Introduces per cgroup timer slack value which will override the default timer slack value once a task is attached to a cgroup. It's useful in mobile devices where certain background apps are attached to a cgroup and minimum wakeups are desired.
Miscellaneous Patches
Added [PATCH] cpu-hotplug: Add the function 'cpu_hotplug_inprogress' by Maya Spivak <[email protected]>
Added [PATCH] printk: Don't allow cpu to get console lock during hotplugging by Maya Spivak <[email protected]>
Added [PATCH] rcu-tree: Check for extended quiescent state at start of gp by Maya Spivak <[email protected]>
Added [PATCH] sched: Do not block when waiting to free old root domain by Maya Spivak <[email protected]>
Enabled fsync disabled (can be disabled by doing an echo "1" > /sys/module/sync/parameters/fsync_disabled in a terminal emulator or as a script for gscript or scriptmanager)
Touchscreen fix set to "3" for more responsiveness during games, etc. (Thanks to vitalij)
Custom CWM Recovery made by af974 (Huge props to him!) based on Team Overcome Recovery (Huge props to them!)
Enabled back key
Enabled Power button to select (less chance of double pressing the Home Button and format sdcard fro some users)
Reorganized, Inutitive layout and more Readable menu
No/Yes Selection Tweak (If you know how to get to Recovery, you don't need that many "No's")

"The Surgeon"
Its basically to make our lifes simpler...
as stated by pulser_g2 here the idea was born on IRC basically because of the constant updates samsung was doing before, and we all felt a little overwhelmed about doing and redoing the mods and themes for every little release, and on top of it, without a changelog.
So basically "The Surgeon" is VRTheme on steroids. What does that mean?
VrTheme based on latest by seshmaru here modified by myself in several ways.
1. It uses sdcard instead of cache, thus making it cross compatible with devices with little cache partition memory (my case the HD2=
2. It has been modified to fit our needs of modding aswell.
So We basically take any John Doe build, no offense intended.
then flash out surgeon and we can do what any flashable zip can do plus:
1. Theme thanks to vrtheme system
2. Flash custom boot logo
3. Change DPI
4. Mod any apk that would allow us (for example, here we use it to provide multidpi for dialer and calculator).
5. Makes a backup of modded apks to sdcard/vrtheme-backup which can be called with the again modified vrtheme restore backup zip file that you should find on the posts below.
to this add:
1 Remove Apks
2 Automatic wiping of dalviks cache
3 adding apks
4 settings permissions, replacing dirs, etc, what any flashable zip does.
and, the best thing of it all, is that, removing specific xmls from the flashins system, makes the surgeon truly universal. This same advanced flashable zip file we have been using since KG6 (yeah, we have been building the roms since KG6, but we did not want to release until we got it all right) with the exception of certain xmls (devs know what im talking about, samsung has been changing smalis and xmls on every darn build).
It also has been proven to work (again without specific xmls) with VillainROM or any rom.
Our main goal was to build a custom base, and, although we consider the base rom to be pretty good, it has nothing spectacular or innovative added to it, its a base rom.
Again, so you guys get this straight.
Base rom contains all the mods that cannot be flashed thru the surgeon.
Thus, the Surgeon is where the magic relies, is where multidpi, themes, mods, scripts, bootlogo changing relies.....jep, that is where the magic takes place.
The Surgeon is pretty straight forward as you can see, no hidden tricks or secrets kept for ourselves, therefore, we consider this to be an opensource project, cause we truly believe that lots of eyes on sources make things a loot better.
So if we get lucky enough with samsung, only one surgeon from now, updates for base rom only.
Surgeon should get updated when bugfixing, adding of features or removal of them.....hopefully i said..
Again, without the help of the VillainRom Team, this wouldnt be possible.
PS: The rom was first intended to be as it is AFTER flashing the surgeon scripts, but, since we can provide a base rom for guys that like ALL of samsung stock features and theme, then this makes us all happy doesnt it?
Universal Surgeons Testing phase
Lets play a bit with this one and try to make surgeon to work on any build too shall we?
Ok here we go with the first one....I just flashed it and it works fine, no bootloops or anything, rom (not androidmeda) is totally themed, dpi hcanged to 192, dialer resized to be multidpi, apps injected, some removed, etc.......This shall make almost (yeah almost) like the docs surgeon script on any build....
Removes the following if existant on build to be flashed upon to
http://pastebin.com/YNC6RPkS
Changes the Bootlogo
Changes dpi to 192
adds some tweaks to init.d
adds color tweak
removes gapps and replaces with latest that supported dpi
adds Spare parts (please uncheck compatibility mode for dpi lower than 240 display correctly)
adds CM7 calculator
Adds gb keyboard I modded to be multidpi
Replaces TWlauncher, replaces with launcerpro
Removes almost all of tw stuff
Removes Kies functionality (and its entry from settings)
And lots more.....
*tested here over Villain Rom, on it and its all good so far
Now rom would be fully themed like docs theme (including custom fadings animations)
pls feedback is appreciated
Universal Surgeon V2.0

Red Pill Kernel
Changelog
RedPill_Rev1.3
Added Newest RedPill CWM Based Recovery by AF974 (Touch Enabled with Battery % and Charging in Recovery) (Huge props to AF974)
Experimental: USB Audio support for DAC devices
Change Back to SLQB for slightly better performance
Removed Net Scheduling/Traffic Shaping via Stochastic Fair Blue Scheduler as this may be causing network issues for some users
Added HFS and HFS+ Support
Added back V(R) but tweaked it to prevent aliased requests from starving other I/O as well (Thanks to franciscofranco for the idea)
Update SIO I/O scheduler to 2012 version by Miguel Boton
Tweaked CPU Freq hyper sampling rate
Added Patch ARM: improve compiler’s ability to optimize page tables by Russel King
Added Patch wakelocks: Allow independent debugging of wake_lock_destroy() (Thanks to Entropy512)
Experimental: Updated Wireless Driver from EL29 Source… (Thanks to gokhanmoral for these files that are “cherry-picked” from his repo) If users report a lot of the dreaded wlan wakelocks, I can easily revert to the stock update3 sources… This is an attempt to solve WiFi problems some are having.
RedPill_Rev1.2
Tweaked tweaks.sh file based on additional information learned and tested recently. (VM System Reading by s2d4 found <a title="Android VM System: Understanding It a Little More" href="http://goo.gl/bQgU0">here</a>)
Reduced number of available governors based on my personal testing... the 4 remaining should serve the needs of those looking for performance, battery life or anything in between.
Removed some more stuff no one used in the defconfig.
Release LA2 based initramfs version as stable (and make AOSP Support Unstable as we don't test that in GB)
Tweaked mount options for ext4 (extended Commit time to 30 and fall in line with the VM System tweaks implemented)
Change from SLQB to SLUB for a little less overhead (vs. a queued allocator) More info on SLUB here: http://lwn.net/Articles/229984/
Tweaked values in deadline and SIO I/O scheduler to give better throughput while attemting to keep a similar latency to the original (if not more aggressive) Based on my initial (indicative, not conclusive... yet) testing, having these in line with the vm dirty, expire, writeback values + ext4 commit=30 + laptop mode to "schedule" write outs to NAND based storage works quite well to balance throughput with latency expected in a mobile device. We took the big picture view instead of copy pasting random "known" good values and challenged some assumptions even we had at the start. The result is a mobile device tuned for good throughput and battery life with above average latency (not the lowest latency out there, but given the benefits of better I/O throughput and potential battery savings + extending the lifetime of NAND Based storage I think it was a compromise worth taking)
Remove V(R) and BFQv3r1 scheduler as the tweaked deadline, SIO and noop are the best we've tested for NAND filled mobile devices. (More on this later)
Added franciscofranco's deadline tweak that "Prevent aliased requests from starving other I/O"
Set deadline as default I/O scheduler
Tweaked deadline i/o fifo_batch for better throughput
Remove set_need_resched from rcutree.c based on https://github.com/drod2169/KangBang-OMAP/commit/717e7a22e42869418084701455c11e690a993fe8 which says:*"if we really are in an interrupt, the attempt to re-enter dyntick-idle mode will invoke*rcu_needs_cpu() in any case, which will force the check for RCU callbacks.*So this commit removes the check along with the set_need_resched()"
Experimental BTHID fix based on latest bthid.c from Samsung Source Releases I found on github (EK02 for Epic Touch 4G Released in December 2011... about 2 months after Update3 Sources were released for the i9100 and about the same time "BTHID broke" reports began coming in.) (Thanks to TDR for the source where I found this fix)
RedPill_Rev1.1
Adjusted Int Voltage of ARM and Busfreq to Stable Values across several devices
Added Imoseyon's suspend code to hyper and sleepy
Adjusted Touch Screen Values back to default (Thanks to Entropy for pointing this out)
Lowered Touch LED Values lower to dim the LED's a bit more.
Added Some Tweaks in the init.rc so they can be set from there and are consistent for anyone who uses the kernel.
Added some experimental compiler optimizations (Haven't noticed much difference, but we'll continue testing)
Enabled deep_sleep and fast_start by default in ondemand, hyper and sleepy
Added backported Conservative governor from 3.2
RedPillKernel_Rev1.0 (Final Rebrand to highlight the Power of Choice... formerly known as HyperKernel or HDK all older changelogs and commits since Update 3 are included)
Custom CWM Recovery made by af974 (Huge props to him!) based on Team Overcome Recovery (Huge props to them!)
-Enabled back key
-Enabled Power button to select (less chance of double pressing the Home Button and format sdcard fro some users)
-Reorganized, Inutitive layout and more Readable menu
-No/Yes Selection Tweak (If you know how to get to Recovery, you don't need that many "No's")
-Mount Internal AND Mount External from Recovery (We figured this would be quite Useful)
Tweaked NTFS automount script to support RW and use native ntfs built in the kernel instead of ntfs-3g (like stock kernel)
Adjusted Max CPU Freq to 1.5Ghz since its more stable then being at 1.6Ghz for those who like to OC
Fixed Bluetooth Devices not connecting properly because of the module not loading properly
Stripped the kernel modules used to bring the kernel size down a little more
Added Tegrak's Home Button Key Tweak (Thanks Tegrak)
Added Stochastic Fair Blue net scheduler (SFB)
Added [PATCH] lib/sha1: use the git implementation of SHA-1 by Mandeep Singh Baines <[email protected]> to improve boot performance by almost 12%
Added [PATCH] arm: remove "optimized" SHA1 routines by Linus Torvalds <[email protected]>
Added [PATCH] arm: remove stale export of 'sha_transform' Linus Torvalds <[email protected]>
Added ARM: 6941/1: cache: ensure MVA is cacheline aligned in flush_kern_dcache_area found here https://lkml.org/lkml/2011/6/16/174
Added ARM_ERRATA_754322 & ARM_ERRATA_754327
Tweaked the Tweaks File with more Tweaks so the Tweakers who like to Tweak can stop Tweaking as its Tweaked by default and No other Tweaks are needed to Tweak it even further. Any more Tweaking brings you to the law of diminishing returns... (you get the point so I'll stop there...)
Set Clockspeed at 1.2Ghz at Boot time to ensure all critical tasks have enough power to perform them while the governors/maxfreq isn't set yet. (Thanks to Imoseyon for this hack)
Add back default sampling_down_factor for Sleepy CPU Governor
Added [PATCH] mach-s5pv310: Make cpuidle AFTR entry less chatty by Entropy512 <[email protected]>
Added various clocksource patches from lkml.org (check the commit log for details)

Kernel Frequently Asked & Answered Questions (FAAAQ)
Where is the source for building this Kernel?
You can find the source HERE. I love GPL and We should all support Open Source Software and its Developers. Please Note that Open Source doesn't mean all of this magically wrote and patched itself... it takes a lot of our FREE time to do this and would appreciate if you let us know how you've improved the code.If you know what you're doing, you can easily build your own kernel too. *Please let me know if you have any improvements you feel should be included and send me a pull request. *If it tests okay, it may be included in the next release.
Does the RedPill support AOSP/MIUI/CM7 ROMs for i9100?
As of Rev1.3, I will not be working to making it work on AOSP/MIUI/CM7 as I only have enough time to test and maintain 1 build. When the ICS sources come out, I may have to make it support it again as the team may release an AOSP based ICS as well.
Why doesn’t the RedPill have high benchmarks?*
That’s done on purpose to keep YOU away. Seriously. The way the VM system is tweaked (dirty ratio’s, minfree values, etc.) + the focus on better throughput in any type of load + prioritizing data integrity by turning on fsync + a lot of other small tweaks all lead to good performance and battery drain in actual use (I like using my device and not keep it sleeping to bloat my battery stats, thank you). This may not give you the benchmark scores you want to be able to show off… which is good since it means YOU stay away from this kernel and continue to rely on benchmarks rather than actual usage.
Does the RedPill support other variants of the i9100 (like i9100g or i777)?
No. It supports only the i9100 International Version. *If you use it successfully on other i9100 variants, please let me know so I can update this page.
Is the Kernel Undervolted by default?
ARM Voltages are stock. Int Voltages and Busfreq Voltages are conservatively UV'd as seen in the source below...
CPU: L0=1500, L7=100
Code:
.index = L0,
.arm_volt = 1450000,
.int_volt = 1100000,
.index = L1,
.arm_volt = 1300000,
.int_volt = 1100000,
.index = L2,
.arm_volt = 1300000,
.int_volt = 1050000,
.index = L3,
.arm_volt = 1200000,
.int_volt = 1050000,
.index = L4,
.arm_volt = 1100000,
.int_volt = 1050000,
.index = L5,
.arm_volt = 1000000,
.int_volt = 975000,
.index = L6,
.arm_volt = 975000,
.int_volt = 950000,
.index = L7,
.arm_volt = 950000,
.int_volt = 925000,
Busfreq:
Code:
{LV_0, 400000, 1000000},
{LV_1, 267000, 975000},
{LV_2, 133000, 975000},
Why a tweaked deadline I/O scheduler?
The deadline I/O scheduler by Jens Axboe has proven itself as a low overhead, high throughput and acceptable latency I/O scheduler. *When tweaked for NAND based Mobile devices, it does even better. *While it "starves" writes by default with a 2:1 Read:Write ratio, this can easily be tuned via sysfs.
Why is my favorite governor (whichever it is) not available?
Simplicity is the Ultimate Sophistication, as Leonardo Da Vinci eloquently said. *Based on extensive testing and user feedback, we gathered that these 4 governors included gave the best performance and battery life on our device. Simple choice to have only the best ones available based on actual testing and feedback. *You will also note that I removed lulzactive and any interactive based governor. This was done after I realized that I was tweaking lulzactive, for example, to behave like governors that do the job perfectly already sans the sleep profile. *What I mean is setting a pump up step of 4 and tweaking other factors such as sampling rate and sample time along with cpu_load (inc and dec) made it behave like ondemand with a sleep profile... *I like it simple so I just included the tweaked and optimized ondemand with sleep profile instead. *You can also make lulz behave like conservative, so I included conservative in there. lulzactive is a tweakers dream... but those who like to keep it simple may find it takes time to configure correctly. *I included only these governors so you all have a simple choice to make in finding your favorite one. *These are all tunable via sysfs so you can skew it towards battery or performance based on what is important for you. *Don't expect uber smoothness and 6 hours screen-on time though... *there will be compromises when leaning towards any of the two factors most users consider important in a kernel.
What are the sleepy and hyper governors?**Experimental CPU Governors
(In order to keep all bugs properly attributed to my experiments and not the original author's, I have renamed it accordingly.)
sleepy (formerly know as solo) is an attempt to balance performance and battery life. Its based on the tweaked ondemand by arighi and is optimized for the SGS2. It includes imoseyon's ondemandx tweaks with some down_sampling and other features that users can set by echo'ing into sysfs. Sleepy is closer to ondemandx in behavior when in action.
It also features arighi's fast_start and deep_sleep detection features. It also suspends at 500Mhz.
hyper (formerly known as kenobi) is an aggressively smart and smooth tweaked and optimized for the SGS2 based on ondemand as tweaked by arighi with some ondemandx suspend features from imoseyon. (Added setting suspend_freq via sysfs and Imoseyon's Suspend Code) Hyper is closer to ondemand in behavior when in action.
It features arighi's fast_start and deep_sleep detection features. It also suspends at 500Mhz.
What is arighi's deep_sleep detection?
From arighi's description on the*<a title="deep_sleep commit" href="https://github.com/arighi/linux-gt-i9100/commit/719732552357f66b11f8c972575b440a8f97d64b">actual commit here:</a>
deep sleep detection via low-power idle notifier
Implement a deep sleep detection mechanism using a low-power idle*notifier introduced in 9487d11.
A new parameter is provided in the ondemand cpufreq governor and*exported in sysfs:
/sys/devices/system/cpu/cpufreq/ondemand/deep_sleep
The deep sleep detection is implemented using the following heuristic.
When deep sleep detection is enabled (deep_sleep = 1) if we detect that*the previous low-power idle state was more than 4x the sampling rate, it*means that we're probably going to enter to a deep sleep state or we're*just resuming from a deep sleep.
In both cases we completely ignore the cpu activity (considering it to*the minimum load), because probably there's a big chance to get back to*the deep sleep soon. If it happens, with this heuristic, the cpu will*enter the deep sleep state at the minimum frequency, that is good for*saving battery life.
What is arighi's fast_start detection?
From arighi's description on the <a title="fast_start commit" href="https://github.com/arighi/linux-gt-i9100/commit/df47f443192c3806277db6aed257421e33c4036f">actual commit here:</a>
fast start detection via low-power idle notifier
Implement a heuristic to detect interactive usage of the device and*boost the cpu frequency to the max.
A new parameter is provided in the ondemand cpufreq governor and*exported in sysfs:
/sys/devices/system/cpu/cpufreq/ondemand/fast_start
The fast start detection is implemented using the following heuristic.
If in the last 4 samples the cpu never entered in low-power idle state,*probably the cpu is very busy. In this case we jump to the maximum frequency immediately.
Why SLQB? (According to its author, Nick Piggin)*
”SLQB is a slab allocator that focuses on per-CPU scaling, and good performance with order-0 allocations. Fastpaths emphasis is placed on local allocaiton and freeing, but with a secondary goal of good remote freeing (freeing on another CPU from that which allocated).”
Why XZ Compression for the Kernel?
Its about 30% smaller and decompresses at just half the speed of gzip... I decided to use it as we have a lot of ram and raw cpu power that can easily handle the extra load xz compressed kernels
XZ compression is set to compress at -9 instead of the default -6 (since XZ decompresses faster when the archive is larger) delivers more performance since in kernel land you don't need to worry about compressing anything back to XZ, these gains in size were enough of a trade-off instead of using gzip by default. (Technically, gzip compressed kernels and initramfs are faster than any other compression method... but for our device we have a lot of raw CPU power and a lot of RAM) (more here http://tukaani.org/xz/)
Why ARM Topology and sched_mc?*(From linaro.org)
"The sched_mc function adds a power saving awareness to the Linux scheduler which is tuned for performance by default. When sched_mc is enabled, the scheduler tries to gather the running processes in a minimal number of cpus and clusters. This choice of the location of a process is done thanks to the cpu topology function which describes the affinity between cpus."
(more info here: https://wiki.linaro.org/WorkingGroups/PowerManagement/Specs/sched_mc)
Why RCU Fast No HZ?
"This option causes RCU to attempt to accelerate grace periods in order to allow CPUs to enter dynticks-idle state more quickly. On the other hand, this option increases the overhead of the dynticks-idle checking, particularly on systems with large numbers of CPUs." The power savings generated from using this, in my experience, outweigh the additional minimal overhead in checking dynticks-idle."
Why rename some modded CPU governors?
I chose to rename tweaked/edited governors as there may be bugs that I inadvertently add with my experiments and would like all these bugs to be properly documented as being introduced by myself. (Personally, it would be worse for me to introduce a bug in a current mainline CPU Governor with my experiments as I'm still learning about tweaking and making changes at this level... and from how I live my life, experience is the best teacher)
Ondemand, for example, is an old reliable and putting all the features I want in there will change the performance I have come to expect from it. I don't expect ondemand to have a sleep/suspend profile for example. So editing/tweaking/optimizing a governor and renaming is the way forward for me. I want to select "ondemand" and know that it will behave like it does in all my devices... reliably handling the load at the expense of battery life.(smoothness above all)
Where do I report Issues or Get Community Support?
Head over to the <a title="Official Kernel Release Thread" href="http://androidmeda.com/forum/index.php?topic=47.0">Androidmeda Forums Kernel release thread</a> or <a title="XDA Kernel Release Thread" href="http://forum.xda-developers.com/showthread.php?t=1288850">XDA Kernel release thread</a> to get support from fellow RedPill Users. *Make sure you included a dmesg or last_kmsg by following <a title="How To File Useful Bug Reports in Android" href="http://androidmeda.com/forum/index.php/topic,12.0.html">my guide on filing Bug Reports here.</a>
How do I show my appreciation? Can I donate to you?
You can show your appreciation concretely in several ways:
Pressing the "Thanks" Button on XDA
Signing Up to the Androidmeda Forums and Pressing the "Super Thanks" Button there
Report issues politely and completely
Donating any amount is completely up to you. *I look at donations as a "tip" for a job well done, rather than a "wage" or a "bounty" to get things done. *And Tipping is always up to you... the tipper. *I won't stop development if you don't donate, that's for sure, as I do this mainly for myself and my HyperDroid mates to begin with. I make more money running my own business than this hobby so “tips” are not a necessity… it just tells me how many people actually find the work useful enough to say thank you via a financial gesture.
This Kernel will ALWAYS be FREE to Download and USE, even if the time spent making it IS NOT FREE. *That's Open Source. (The time people spend on open source projects could have been used to spend more time with their families, for example. But the Devs commitment to get something done right is almost always tugging at him to Dev just a little bit more) *
*I've personally donated to Devs who've done things I would never have been able to figure out at the time they did figure stuff out. *Learning anything new takes time and time, in my book, is more important than money as I can't turn back time, while I can always earn money. SO I donate to Devs who spend their free time making Stuff better and easier for those of us who haven't figured out how to get it done.

Hello ladies and gents,
This is my surgeon for Androidmeda HyperDroid. I won't bore you with a long block of text. So here's a short layout of the features.
Features
Flashed over Androidmeda
Fully Odexed or Fully Deodexed (2 versions)
RTL patch compatible. For Jkay mod based builds you MUST use the deodexed version. For TSM both are working
Blue theme on most applications (I have drawn a line between blue being the dominant color and everything just being ... blue)
Stripped almost completely to the bone. About 90 system applications removed
Jkay or TSM mod compatible (2 separate versions)
3G/G/Wifi and Network Signals turn blue when connected to Google Servers
DPI is set at stock 240
Includes my modified TouchWiz Launcher (v2.4 Page Number 4 default Home Page)
Includes my modified Samsung Keyboard
3 very useful applications installed in /data/app (SmartRotator, AutoMountUSB, homeMYhome) and OdexMe in /system/app
Rosemary Fonts from SGS (select from Menu > Display > Screen Display)
Creates a folder in your /sdcard named Walls with SGS2 stock wallpapers and Galaxy Nexus Wallpapers
Up to 12 notifications in Jkay mod that are rearrangable. 5/6 notifications layouts (non-deluxe) come with a carbon fiber background.
Edited Settings.apk to remove unused entries
Here is the LIST of the applications that have been removed. Read it, and if you need some applications that will be getting removed, follow the instructions below.
Short description of the surgeon
This surgeon uses a unique reodexing script to turn the deodexed base ROM back to odexed. This script was done using bolts and bits of reodexing scripts floating around. (Jkay and TSM versions use different odexing scripts and procedure) Many kudos to those people.
This is best suited for the users that remove most bloatware and install Titanium Backup to restore their applications at once. Should you not be one of those users, there are some suggestions below to replace stock applications with.
It is prefered you use odexed themes. But you can flash deodexed themes, as well, so long as you leave /system/framework/*.jar's untouched. Open the theme .zip, note the apks that the theme contains and once installed, remove the appropriate odexes. Then run Paul's OdexMe application (this is an edited version).
Email and Email widget are included, however Premium accounts cannot be created. The push notifications of Social Hub does eat up a lot of RAM and Battery (a lot of battery in fact) so please use Hotmail/Yahoo mail push apps.
homeMYhome app (renamed for easiness into Double Tap - many thanks to c3k!) replaces VoiceToGo double tab feature with another app of your choice. Make sure you have Double Tap enabled if using Jkay's version.
AutoMountUsb enables USB automounting once plugged in, and SmartRotator allows you to select which applications you want to rotate or not

Kernel Changelog
HyperKernel HDK: The underrated, quietly confident and remarkably smooth kernel...​Kernel Source:​https://bitbucket.org/sarcastillo/ultimate-kernel-sgs2​
Download Link:​​The Latest HyperKernel is bundled with the newest HyperDroid.
A separate thread will be introduced that will usher in the release of the kernel download separately.
v1.2 is already in testing and will be released as soon as my heavy usage with heavy UV and OC are done. (In 3-5 days)​
FYI If anyone should ask... we currently use the CodeSourcery Lite Toolchain. I was just about to play with other Toolchains but decided against it because after doing some research I found this R&D by Ezekeel. Thanks to Ezekeel for the useful information.

HyperKernel HDK v1.1
-Cleaned up choice of CPU Governors and reaaranged them so that when selecting them in CPU Control Apps such as VoltageControl by xan (which is highly recommended fo use with this kernel), its arranged by its "focus and intent" (based on extensive testing on all default Clocks and Voltages) from "battery focused to performance driven".
-With this focus on simplicity stated above, the only governors available are the following:
-lulzactive (interactive based cpu governor by Tegrak) extremely flexible... by default it has a screen off profile and can be tweaked using init.d scripts or the lulzactive app by Tegrak to be battery centric or performance oriented.
-sleepy (ondemand based cpu governor formerly called "solo" edited by Pongster) loves to sleep and idle at the lowest set frequency, hence the name change from "solo" to "sleepy". This can be tweaked and tuned using init.d scripts as well.
-conservative (good battery savings by default due to its slow ramp up and ramp down but tunable for performance) defaults are slightly tweaked for better performance than default conservative.
-lazy (ondemand based cpu governor by Ezekeel) described by Ezekeel as "maybe a better version of ondemand" and for good reason as it gives a good balance between battery life and performance. also tunable using init.d scripts.
-ondemandx (ondemand based cpu governor by Imoseyon) this features earlysuspend features and downsampling which looks for the lowest frequency which can sustain the load while keeping idle time over 30% and tries to try to decrease to this frequency.
-ondemand (old reliable thats been tweak by arighi to support deep_sleep and fast_start) these features try to detect if the CPU is coming from a deep sleep and is more likely to sleep again and thus limits its frequency to the lowest possible that can handle the operations needed. fast_start checks if the CPU needs more "ooomph" and jumps to the highest frequency faster to enable it to complete the operation the system needs to complete. (like during boot-up)
-Added sysfs interface for setting suspend frequency for sleepy CPU Governor. Default is 500Mhz. Min Frequency is 100Mhz, Max is 1.2Ghz (Why would you need to suspend beyond that right?)
-Added some tested tweaks from the past few months of testing with HyperDroid ROM.
-Removed the + sign at the end of the versioning thanks to franciscofranco.

-Removed some governors that are not as effective based on testing. (Removed skywalker, SmartAssV2) Use lulzactive if you want an interactive based governor. There are 8 governors in total available. Default is kenobi. You can tweak it by echoing into sysfs as usual.
-Added some tweaks in Kernel thanks to Erasmux and everyone involved in the discussions HERE: http://forum.xda-developers.com/showthread.php?t=786919
-Enabled Kernel Debugging and Schedule Debugging for the tweaks from Erasmux et. al.
-Fixed LOUDER App Compatibility thanks to @supercurio and @gokhanmoral
-Integrated gokhanmoral's implementation of Tegrak's updated lulzactiveV2 (Huge props to Tegrak and gokhanmoral)
-Tuned lulzactive for HyperDroid defaults. (Can be changed using tegrak's lulzactive app from the market)

v2.1 Ultimate
-Enabled AFTR by default and tweaked scheduling a little bit for performance.
-Patched to Add v5 ARM cpu topology definition by "Vincent Guittot"
-Enabled sched_mc_power_savings
Add ARM cpu topology definition
The affinity between ARM processors is defined in the MPIDR register.
We can identify which processors are in the same cluster,
and which ones have performance interdependency. We can define the
cpu topology of ARM platform, that is then used by sched_mc and sched_smt.
The default state of sched_mc and sched_smt config is disable.
When enabled, the behavior of the scheduler can be modified with
sched_mc_power_savings and sched_smt_power_savings sysfs interfaces.

v1.6 SynergySeries
- Added XZ decompression support for kernel headers and initramfs... (Thanks to faux123)
- Added some XZ related fixes thanks to the original contributors.
- Tweaked XZ compression to compress at -9 instead of the default -6 (since XZ decompresses faster when the archive is larger)
and since in kernel land you don't need to worry about compressing anything back to XZ, these gains in size were enough of a trade-off instead of using gzip by default.
(Technically, gzip compressed kernels and initramfs are faster than any other compression method...
but for our device we have a lot of raw CPU power and a lot of RAM) If you don't trust me, trust the smoothness of the kernel at its current setup.

Code:
Why XZ? Some XZ Decompression details: (more here [url]http://tukaani.org/xz/[/url])
- Its about 30% smaller and decompresses at just half the speed of gzip...
I decided to use it as we have a lot of ram and raw cpu power that can easily handle the extra load xz compressed kernels and initramfs bring...
based on my current understanding, it decompresses really fast so the boot time and other processes that depend on these are still fast while keeping the kernel lean and mean
- Huge props to Lasse Collin and Igor Pavlov for XZ... quite an amazing piece of work there.
- Our kernel with initramfs and complete features (nothing made as modules or removed) is only 5.8MB yup... you read that right...
v1.5
- BFQv3r1 included (backported from 2.6.38)
- Enable Net Scheduling and Queueing for a more stable and faster loading of pages and apps that depend on a network connection (e.g. Market)
HTB by default http://luxik.cdi.cz/~devik/qos/htb/
Why HTB? See here: http://luxik.cdi.cz/~devik/qos/htb
- Experimental Support for Non-Samsung ROM's thanks to gokhanmoral's siyah_feature_set which I ported from his kernel tree and used his initramfs as a base
- Experimental NTFS automount for OTG devices (you'll have to do a little more work to enable sdcard as ntfs) (Thanks to gokhan for the hotplug script)
Note: fuse.ko is built in statically into the kernel, as is cifs.ko and usbserial.ko
- Enabled fsync disabled (can be disabled by doing an echo "1" > /sys/module/sync/parameters/fsync_disabled in a terminal emulator or as a script for gscript or scriptmanager)
- Enabled fast_start and deep_sleep for 2 other ondemand based governors: solo and kenobi
- Turned Off CFS bandwidth for a small performance gain

Experimental CPU Governors:​
*Experimental CPU Governors:
Added 3 modded CPU Governors tweaked and optimized for the SGS2
*skywalker is a smart and smooth tweaked and optimized for the SGS2 based on SavagedZen. (Right now I just tweaked the numbers, but I plan to try and add more mini features. In order to keep all bugs properly attributed to my experiments and not the original author's, I have renamed it accordingly.)
It suspends at a freq of 500Mhz. It wakes up at 800Mhz.
*kenobi is an aggressively smart and smooth tweaked and optimized for the SGS2 based on ondemand as tweaked by arighi. I also ported the features of Ezekeel's lazy governor. (which is based on ondemand as well) (In order to keep all bugs properly attributed to my experiments and not the original author's, I have renamed it accordingly.)
*solo is an attempt to balance performance and battery life. Its based on the tweaked ondemand by arighi and is optimized for the SGS2. It includes imoseyon's ondemandx tweaks with some down_sampling and other features that users can set by echo'ing into sysfs.
It also features arighi's fast_start and deep_sleep detection features. It also suspends at a freq of 500Mhz.
