Sorry for disappearing guys, I wasn't in the mood for posting or working on the kernel: unfortunately it looks like I bricked my phone.
I couldn't believe it myself but as soon as I restarted it phone after CWM-flashing my usual JPO rom, going back from official JPU+803.pit, the screen went black and never came up again, no matter the key combination. No signs of life besides warming up slightly after pressing power or connecting the USB cable. No luck with a JIG cable aswell, tried all the way from 290K to 315K Ohm and nothing happens... I guess there's nothing I can do.
The problem is, I came back to Europe last month and official Samsung centers around here are refusing to offer repair services on US phones because of some kind of freak policy they have, even if I pay myself.
Update Dec 13:
I have no words to explain how thankful I am: PAulyhoffman offered to donate a spare phone he had, and promptly shipped it on the same day.
A special mention goes to Patrick Richter, Pauly's father in law, who just passed away on Saturday: a most generous man in honor of whom he would like to dedicate the donation.
I've already covered the shipping fee myself but customs will add a variable amount in taxes (most definitely 20% of original value as they usually do, although the specified value is just $100).
Hoping customs won't hold the package over the holidays, untested version versions will have to do for now.
HUGE thanks go to every single one who offered help, I really am moved by the affection demonstrated by this wonderful community.

I've compiled a Kernel based on Sztupy's ULF and xcaliburinhand's re-oriented kernels, including OC/UV support, 340Mb RAM and compiling optimizations.
Being based on the i9000 JPM source, it comes with every issue xcaliburinhand's kernel might have.
As I have absolutely no kernel programming knowledge, all credit goes to the respective coders: I've merely copied, pasted and compiled things, so I won't be able to offer much additional support or modify any of the function unless they provide source.
THIS IS A FROYO KERNEL, USE ONLY WITH A 2.2 ROM, PREFERABLY AN I9000 ONE
DO NOT USE SETCPU
Features:
- Sztupy's Ultimate Lag Fix V. pre-0.4https://github.com/sztupy
Multiple configurable Lagfix options:
Ext4 No-Journal DATA: /data converted to Ext4 with no journaling, everything else stays RFS
Ext4 No-Journal ALL: /data, /cache and /dbdata converted to Ext4 with no journaling
Ext4 DATA: /data converted to Ext4, everything else stays RFS
Ext4 ALL: /data, /cache and /dbdata converted to Ext4
Ext2 DATA: /data converted to Ext2, everything else stays RFS
Ext2 ALL: /data, /cache and /dbdata converted to Ext2
Advanced options: lets you specifically configure each partition and eventually add an Ext2 loop on top of them
Ext3/4 mount options: enables writeback journaling mode
(Using BIND_DATA_TO_DBDATA you might run out of space with many apps installed)
Suggested configuration (Ext4 ALL):
DATA_FS=ext4
CACHE_FS=ext4
DBDATA_FS=ext4
DATA_LOOP=false
CACHE_LOOP=false
DBDATA_LOOP=false
BIND_DATA_TO_DBDATA=false
Use FAST mount opts
You will get a "Configuration has changed" recovery screen at the first reboot after setting lagfix options, it's perfectly normal. If you wish to keep your current data, select the first option and wait (a separate backup is recommended).
- Modded CWM integrated
- CWM pre-installed (no more install from update.zip)
- reboot to 2e recovery
- reboot to download mode
- tweaking options
- root from recovery
- configure lagfix

If you do not want to mess with commands, use Xan's Voltage Settings app
- do note that you're subtracting voltage from the default setting, which varies with frequency:
Code:
1600MHz CPU 200MHz GPU 1400mV
1552MHz CPU 194MHz GPU 1375mV
1488MHz CPU 186MHz GPU 1350mV
1440MHz CPU 205MHz GPU 1325mV
1400MHz CPU 200MHz GPU 1300mV
1344MHz CPU 192MHz GPU 1300mV
1288MHz CPU 184MHz GPU 1300mV
1200MHz CPU 200MHz GPU 1300mV
1000MHz CPU 200MHz GPU 1275mV
800MHz CPU 200MHz GPU 1200mV
400MHz CPU 200MHz GPU 1050mV
200MHz CPU 200MHz GPU 950mV
100MHz CPU 100MHz GPU 950mV

CONFIG_UACCESS_WITH_MEMCPY=y
CONFIG_KSM=y
# CONFIG_CGROUP_DEBUG is not set
# CONFIG_PREEMPT_NONE is not set

Once again, none of it comes from me and all credit goes to the original developers, especially xcaliburinhand, raspdeep and hardcore
Nevertheless, if you're feeling particularly generous and have already provided for the developers, I'll gladly accept a token of gratitude (after all, being so ignorant I did have to invest quite a bit of time into it).
Everything comes at your own risk, I offer no support at all.
Thank you aleadam, ReedX50v, junktzu, shaolin95, Shane, krl66, Smokestack76, Henry, Xstop, lpsi200, Arffer, newter55, Lertets, txRangerXDA, id10terrordfw and Bedwa for your donations.

reorganized performance levels with a few additions
- v1.5.1
skipped, integrated in 1.5.2
- v1.5
updated raspdeep's OC/UV to v300
multiple performance levels:
100
200
400
800
1000
1200
1360 (GPU downclocked, don't worry performance improves anyway)
1400
1440 (GPU slightly overclocked)
1460 (GPU downclocked)
Default clock at 1200MHz, additional frequencies can be enabled by editing /sys/devices/system/cpu/cpu0/cpufreq/states_enabled_table
in order to update the states table it's necessary to edit to 1 /sys/devices/system/cpu/cpu0/cpufreq/update_states (echo from terminal or by manually editing the file, just like the states table)
added compatibility with Xan's voltage app v2.0 (please update, v1.9x wouldn't work correctly)
reduced 14xxMHz default voltage to 1.3v
updated CWM to include Hardcore's latest additions
slight menus reorganization
updated optimization scripts (now including battery optimizations and CIFS support)

built-in support for ext4 mount optimizations (writeback mode)
- v1.4.3
fixed 2e recovery, now completely functional
added 1350Mhz, 1400MHz and 1450MHz variants, only available as ODIN packages. The latter two have a default voltage of 1350mV. Keep using Xan's Voltage App v1.98b's 1200MHz setting to undervolt, higher frequencies replace the 1200MHz step, bear in mind the app doesn't show the updated frequency/voltage. Remember to reset said setting before upgrading and please realize how 14xxMHz will only run on few lucky devices
from now on there won't be a CWM version for 1350MHz+ and XT variants as well as a release integrating the modem, just install it on its own if necessary
- v1.4.2
implemented Tiny RCU
re-enabled Samsung's bootanimation when there's no bootanimation.zip
re-added -noatime optimization script
XT variant: 1280MHz, config optimizations: HZ=500, PREEMPT_VOLUNTARY, UACCESS_WITH_MEMCPY, KSM (possibly unstable, slightly higher performance and battery drain, might be necessary to lower UV)
- v1.4.1
fixed BLN (flashing as update.zip or re-enabling it from CWM might be necessary)
- v1.4
raspdeep's OCUV updated to v217
implemented fastscaling for 100-400MHz frequencies
added 1280MHz variant (UV setting for 1200MHz applies to 1280MHz, so reset it)
ULF updated to pre-0.4, modified to support bootanimations
fixed potential /system corruption
integrated JK3 modem in CWM flash package
kernel version updated to reflect frequency variant (#140-1280 / #140-1200)

- v1.2
increased available RAM to 343Mb
updated BLN to v2.2
- v1.1.1
enabled init.d script execution on boot (Xan's app voltage settings are now being kept)
- v1.1
added BFQ I/O scheduler
updated Voodoo color&sharpness
BLN reverted to v2.0, now working (flashing from an update.zip is required to install the Library)
- v1.0.1
fixed JFS filesystem support, added bootanimations, BLN still not working (no clue why not, waiting for xcaliburinhand's upcoming update)
- v1.0
initial release
RESET ALL UV SETTINGS (DELETE INIT.D SCRIPTS) BEFORE UPGRADING TO HIGHER VERSIONS

Modules and mem config extracted from samsung's JPU kernel: DO NOT USE THIS KERNEL ON JPU FIRST BOOT OR YOU'LL GET AN ENDLESS VIBRATING BLACK SCREEN, BOOT ON SAMSUNG STOCK AND ONLY THEN FLASH THIS KERNEL
The XT variant is slightly faster but can cause instability (which might require higher voltage) and charging death.
Voltage Control 3 supports enabling higher frequencies from the freq table, but doesn't yet let you disable selective ones.
To disable a certain frequency its corresponding value in /sys/devices/system/cpu/cpu0/cpufreq/states_enabled_table has to be set to '0'.
Changing update_states is no longer necessary. That file can either be manually edited or modified through an 'echo' command, which is much more convenient if you're in front of a PC and able to use ADB.
It's a volatile RAM file, which means changes made to it won't stick through reboots; I've included a script that reapplyies settings on boot in the CWM package (also attached to this post).
Let's say you wish to overclock to 1400MHz and disable 1288-1344:
1344MHz corresponds to the 6th value, 1288 to the 7th:
Code:
#!/system/bin/sh
#SET OC - below are GHz decimals (i.e. 1.60GHz, 1.55GHz, 1.50GHz and so on)
#60 55 48 44 40 34 28 20 00 .8 .4 .2 .1
[color=red]#[/color]echo 0 0 0 0 1 [color=blue]0[/color] [color=blue]0[/color] 1 1 1 1 1 1 > /sys/devices/system/cpu/cpu0/cpufreq/states_enabled_table

Awwww that's a deal breaker for me, need bln badly. But yes finally, sztupy ulf on the cappy.
BLN now included, untested.
Awesome. I've been trying to figure out the how to do all this as well. I edited the code this morning at work and I just thought I'd check XDA while CodeSourcery finished installing...and what do I see?
I'll be flashing this immediately. FWIW, I've actually been running raspdeep's OC/UV 2.0 since Monday. I have it set at -100UVLF, -75UVHF, and I've had absolutely no problems with it at all, but it seems to be a YMMV situation. I don't think all processors can handle the UV. Even with (I think) unhelpful's, JAC's, and kingklick's kernels for the Galaxy S, phones handle the UV fine, some don't. Battery life is amazing with this though.
Also, I've had problems with screen off settings with setCPU. You probably don't want to use them at all.

Can I get this uploaded in Shep's rom since he is "unavailable" until tomorrow Since you are so fast at making peoples dreams come true
/sarcasm
so has anyone run this yet? it seems pretty alpha and my phone just went into download mode to test it
By the way everyone - the UV is still what I think raspdeep considers alpha. You will probably want to stress your system a bit to ensure it can handle it. I found that with -100UVLF/-75UVHF flash video was a little bit choppier than with the settings at -75UVLF/-50UVHF.
That said, it has been steady for me over the last couple days, no problems at all with it. I can watch flash video and my CPU temps still stay under 100.
Also, link to xan's UV GUI seems to be missing - so here is another one.
And having alogcat installed and knowing how to use it would probably be the best practice if you want to help raspdeep make this even better.

What lagfix are you trying to install? I got that with trying to use all=jfs, switching to all=ext4 worked.
BLN doesn't seem to be working. Yes I did enable it in the custom recovery menu, and yes I'm using a version of Mms.apk that supports "led notifications."

Goo Manager Support (NEW!)
You can now download my custom kernels, tweaks, etc from Goo Manager, available on the Play Store. Goo Manager is similar to ROM Manager, except it works very well with TWRP 2.x
First time use instructions:
Set Download path to: /sdcard/goomanager/ in "Settings" (This is important as the location on Android and TWRP need to both be exact same!)
Go back to the main screen in Goo Manager and click Browse Compatible Roms
Choose 'godmachine81'
For kernels choose a500_kernel (you are welcome to look around in my other directories)
Choose the release you wish to download
Choose 'begin download'
You will see a notification for 'Download Finished' - Tap on it
It will prompt you to Select Zip(s) to flash, you may choose more than 1!
After you have selected all the zips you want to flash, go to the option 'Order and flash selected' or if you want to add a zip from a custom location, choose the 'Add zip from another location option'
Once in the Order and flash menu, it is important that you set the order to flash in the proper order, when you are sure it is right, then click Flash (First time you use Goo Manager, it will prompt you that an OpenRecovery is needed, choose that you already have one)
After You click flash, the system will reboot to TWRP, flash your .zip files, and reboot back to android without any user interaction.
ZRAM
What is it?
Zram was developed so that systems with a limited amount of physical ram may allocate a percentage of that to a system swap device using compression. By compressing the data that is in the swap space you can fit more data into the same amount of ram. For example App#1 is consuming 500mb of a total 725mb ram, this leaves you with 225mb free. If you have Zram enabled then App#1 may begin to swap to the zram device, when doing this you will have an advantage, because any amount of data from App#1 that gets swapped out to Zram will be compressed meaning it is actually using less physical ram. So instead of only 225mb free of 725mb you may now end up with something more like 400mb free because data from App#1 is compressed in Zram, in this example thanks to compression you cut the 500mb memory usage of App#1 to 325mb. Zram should have a minimal impact on performance while giving you the benefit of fitting more data into the amount of physical ram your device has.
HOWTO
This kernel includes functional ZRAM support, however to take advantage of it you must enable it from userspace (Android). Cyanogen Mod has an option in Settings > Performance > Memory to enable Zram, however it doesn't properly work - I'm not sure exactly how it is coded in the cm sources, but when you enable zram it doesn't create the zram swap device like it should. To work around this I wrote the following flashable .zip files that contain a script to automatically create the zram swap device at boot, please download and flash the size you wish to allocate to zram:
Zram - 100MB (14% ram)
Zram - 150MB (20% ram)
Zram - 200MB (28% ram)
Zram - 250MB (34% ram)
Zram - 300MB (41% ram)
Zram - 350MB (~50% ram)
To Disable/Remove Zram
In the event that you want to disable Zram then just remove the file(s) at:
/system/etc/init.d/50zram-*
After the 50zram- file has been removed, just reboot your device and you will no longer have Zram enabled. To re-enable just reflash one of the above files.
ChangeLog:
2.0
Backport several bits mainline code from Linux 3.5 - including Security, ARM Libs, MM, and Android specifics
Zcache + Cleancache added
Ability to concatenate kernel cmdline configuration to Bootloader's cmdline without breaking compatibility with any bootloaders ( needed for zcache/cleancache to work)
Zram patches and updates
Clean up dmesg logs
Deadline IO Sched tweak (1:1 ratio writes/fifo) - VR remains default IOsched
CONFIG: turn off some verbose logging/debugging to reduce overhead, enabled Load Lens Correction Data to smooth out camera operation
TweakIO init script included by default to optimize disk read/write performance
Several other small patches and tweaks to underlying sources
1.6
Minor update adds support for USB-DVB devices, provided in two separate files for convenience to users who do not wish to use DVB-USB all that is needed is the kernel package, for users who wish to use DVB please flash both the USB-DVB and the Kernel pkgs. **Warning please only install the USB-DVB package if you have the matching kernel pkg installed. This may require you download firmware for your DVB device to work, also for the modules to load automatically you will need an init script that loads the needed modules for the device - reason I didn't do this is because there are 79 different modules for universal support, it would be crazy to load them all for everyone all the time, so if you want this feature please do some research on how to get the proper modules (and firmware if needed) to load properly automatically via init script. For help join #iconia-dev on irc.freenode.net and look for godmachine81.
1.5
Add support for USB devices [USB Audio, game controllers, mice, keyboards, etc]
Adjust GPU/CPU voltages and frequencies - should have impact on GPU performance
Interactive governor default again and backported from Nexus 7 / NVidia Grouper kernel v 3.1
1.3a
Script: toggle-ag now included in zip, installs to /system/xbin/toggle-ag
Default IO Scheduler V(R)
Default CPU Governor Lulzactive
1.2b
Bug Fix release for 1.2 - BFQ randomly causing "black screen" issue immediately after boot animation, preventing full boot - reboot resolved issue in most cases, but comes back at random on boot - Setting default I/O scheduler to NOOP until BFQ issue is resolved.
1.2
Autogroup per UID instead of TTY task (huge improvement to autogroup on android)
Set BFQ as default I/O Scheduler
Allocator: Switch to SLUB from SLAB
Remove verbose debugging symbols
Set proper firmware/calibration paths for WiFi in configuration
1.1
Add userspace support for undervolting
GPU OC (400mHZ) on CPU OC > 1000mHZ
Fix "Recent Apps" bug - The glitchy behavior when loading an app cached in the "Recent Apps" menu. Pointed out by DarkNight
Tune SmartassV2 for better behavior and ideal freq set at 760mHZ
Add the following CPU Governors: Lionheart, SavagedZen, Lazy, Scary, Intellidemand, LagFree, Wheatley
Deprecated the non-autogroup release also known as (default)
various other improvements to CPU, voltage, video.
1.0.1b
Add SmartAssv2 CPU Governor
Fix LOCALVERSION
1.0.1
Patched MMC_CAP_ERASE as precautionary to avoid hard brick
1.0-pre
V(R) I/O scheduler Added

Well,
I'm always looking to flash things. I suppose it doesn't include 3g and GPS for the 501?
Should be a simple merge to use ICS 501 source from Acer.
However, I'll throw in a flash just to check install. Will report back later. Supermarket trip first.
MD
EDIT: I am to assume this is for ICS. Also, I noticed in your install script, there is no provision to delete current module files. I would suspect this would cause an issue if you already have an OC/UV kernel with modified ko files?
Probably is best to modify the IS to delete current lib/module files, and replace them with the required ones.
Hi,
I flashed the kernel over cm10 preview with TWPR and it boots up fine.
I found one bug yet:
when selecting lagfree governor the tablet freezes and reboots.

PSensor3G the appropriate driver for what you are wanting? It isn't a default in the A500 config, but I can definitely recompile it with it turned on.
**Edit - I had already merged in the A501 code drop, so if those things are not working it should be as simple as altering the config. I build simdetect in static instead of a module - it was a new feature in the 501 code drop, if it has issues being built in statically please let me know, as far as gps goes, it is included and *should* work, however I have no way of testing these things first to make sure.
GPS should work, don't see why it wouldn't.

Interesting as that isn't happening with the A100. I'll check into it or maybe remove lagfree, it's kind of misleading anyway, because imho it produces more lag than any of the other governors..

The script will remove modules from system/lib/modules and replace them with 1 module which is the wifi module, everything else is built into this kernel, it WILL NOT cause an issue at all, when you reflash a different kernel it should overwrite the modules installed by mine. Aside from that nothing in the ramdisk will be touched. And this is for HC/ICS/JB, it should run on any of roms you have as this entire kernel is built static, except for the wifi module.

I would like to see extreme edition and yes lagfree makes it freeze, also smartassV2 made it freeze ones , I use SavagedZen and it is very smooth.
So cif and other are build in kernel.

Thanks for reporting, I will check into what the differences would be between how the A500 and A100 boards handle the cpufreq transistions between gov. Not sure why they are causing issues with A500 and not with A100/A200 since they are all tegra2 and the cpufreq drivers are all tuned for the same processor, that's a bit weird, but thanks for reporting they are having issues, I will take note of that with A500 and may remove them or may patch whatever is necessary causing the lockup on gov change. Thanks again
**edit: yes all the FS supports are built in - if you have need for them being modules due to problems being built in statically let me know and I can just rebuild them as .ko instead of static. - Not had issues with any of the SMB/CIFS connections with A100 and static CIFS. Also NTFS is built in for whoever might have a weird sd card that is formatted with ntfs instead of fat32, or if they need to mount NTFS partition in any other manor
**edit2: haven't built A500 Xtreme edition yet, A100/A200 are working with xtreme until 100% load is reached for a duration of around 2-3 minutes and then freq nose dives to 216-456 and never raises back, has to do with the voltages clocks in dvfs / tegra2_clocks It's on my todo list of things to fix, and if I get it fixed I'll compile for A500. Kinda doing the A500 work in the blind, but doing the best I can to not have the device present.
Gotta clear something, not smartass V2 made it freeze it is caused by switching from interacriveX to SavageZen.

Thanks, that makes more sense now, as I just added interactiveX into my sources today and I haven't fully tested it. That's why there isn't a new release to the A100/A200 guys yet and I have done a few more things also as tests. If interactiveX is an issue it can be removed, I can just build again out of a 1.3 / 1.4 tag and eliminate that issue. I will be testing on my a100 to try to reproduce the problem. appreciate the info
**Edit and yes I can reproduce that bug on my A100 - I greatly appreciate the info civato! It isn't just switching to smartassv2 from interactiveX it is when switching to any other governor from interactiveX - I will check the sources for how interactiveX is handling the handoff right now
**Here is what I have concluded on: interactiveX has a serious bug when switching to another governor, I have looked at the sources and tried to debug dmesg/logcat info while the switch occurs and can't come up with any relevant information needed to pin point what the exact cause is with interactiveX - I made a few modifications on how the governor gets disabled when switching to another governor - didn't help... Still happens. Good news is: The regular 'interactive' driver that we have is backported from the nv grouper 3.1 kernel and should be much better at powersave/performance ratio than the older 2.6.3x interactive governors we have been using. So what I am going to do for you guys is the same thing I'll do for the A100/A200 guys (which never had this problem because interactiveX was never released to their devices - A500 kernel got compiled before I have pushed anything upstream to github or made other flashables.) I am going to take out interactiveX completely, keep the backported interactive assuming that you guys aren't experiencing any issues with 'interactive', and we'll make the release 1.5. Hopefully that will clear up any bugs you may have with this alpha test and people can begin to use this as a daily driver on their tabs. I appreciate all the help you guys have given me with this alpha release, not only have you helped me to find a bug with the A500 but also with A200/A100 before I released the downloads of 1.5. Thanks guys!

Of course that wouldn't work since the ntfs module is built in (would conflict). I will make it module and recompile, need to see what is in the user land that depends on ntfs being a module and not static.

No , no luck , ntfs is not working , I did 2 tests . One without modding the ramdisk and one where I added the following line "insmod system/lib/modules/ntfs.ko" .
Did you try with the ufsd.ko module that comes with the acer A500 stock kernel?
If you download the kernel from my flexreaper thread , see my sig you can find it there.

if you have that handy can u stick it in /system/lib/modules and reboot to see if it loads, not sure why there is a problem as i have module support for other versions enabled.
Civato: not exactly sure why this would be any different if you have the same .ko file and have already placed it in system/lib/modules/ and rebooted, but here is a download that contains the ntfs.ko and ufsd.ko in the modules if you don't mind testing it:
https://github.com/downloads/godmac...Custom-Kernel/gm-a500-v1.5-alpha-3-signed.zip
Just an initial look see. 3g and GPS work for the 501.
A little sluggish on first boot for a minute, but settled down. Will take a couple days to do battery rundown, and to check on 3g screen freeze and SOD. These issues haunted the 501 when it came to UV kernels. It's a lot less tolerant to UV than the 500 due to the 3g.

Here's a custom kernel for you all to try out. It should work with any CM10.1 (some nightlies, but not all), CM10 or CM9 ROM that loads from moboot with uImage.CyanogenMod (if you don't understand what this means, don't use it). Pick your specific ROM. Not tested with all ROM's, so YMMV.
Here's a few facts:
Compiled with Linaro 4.7 toolchain
Complete with jcsullins patches for low power demand, wifi sleep, etc.
Complete with _Dorregaray's_ camera hooks
Improved entropy depletion routines speed file reads
Optimized AES and SHA1 encryption routines speed boot up and file decryption
Overclockable to 2157MHz if your ROM allows frequency settings
Level 2 frequency OC to 1914MHz
Stepped 2D & 3D GPU up to 320Mhz
Additional governors and schedulers
Use Kernel Tuner for tuneable parameters in the kernel
READ HERE FOR INFORMATION ABOUT GOVERNORS AND SCHEDULERS: Guide Link
Instructions: Download and flash the ROM version you currently have installed. No system/full wipes or cache clearing required.

I flashed it a couple hours ago over SGA's latest JB ROM. And I can't get the clock to steady step over ~1.89GHz on any governor. And the performance at 1.89GHz is worse than 1.78 as per my Antutu scores. I tried using the built in CM CPU settings, SetCPU and System Tuner and the situation is about the same.
There are times when it looks like I got the CPU to step up to 2.1GHz but when it's actually stuck at 1.188GHz.
So the setting are there but they're unusable. Any suggestions?

FWIW, I'm running the latest CM9 nightly and after I flash this kernel my Touchpad gets stuck on a black screen after the second boot splash image. The bootanimation would never start. I would have to hard reboot into moboot then flash a different kernel to get the TP to boot.

1. Have you tried setting to the performance governor? I had the same problem when I set to 2.157 GHz it didn't actually go above 1.836 GHz.
2. Also try rebooting and then try to set it again. Try using No Frills CPU Control.
3. Overclocking above 1.782 GHz doesn't seem to present any HUGE benefits right now. It will drastically lower your battery life.
4. Benchmarks don't really equate to real life performance.

1. I've tried every CPU speed above 1.782GHz in performance. And tried multiple of different speeds on interactive and ondemand. If I set it to anything over 1.782GHz it would get stuck 1.188GHz. Basically, CPU stepping is broken above 1.782GHz.
2. I've rebooted between all runs with different CPU apps. I don't know about No Frill CPU Control, but how would it be any different from the apps I've already used or the built in CM CPU control settings. I will try it out in a bit but I'm pretty sure it wouldn't really change anything.
3. Attempting to overclock over 1.782GHz seems to make the device slower in general.
4. Sure, benchmarks don't equal real world performance, but we're talking about less than half the score. Also, the entire device was just less responsive in general.
I set mine to 1.512 (which is the tp's true capacity), and 384, to deal with sod. I use the unofficial cm10, 03/08.Works well, so far.....

1.5GHz is the TouchPad's true 'factory maximum CPU clock speed'. Who knows what its "true capacity" is. Many devices with very good SoCs have an overclock threshold of about 30-50% and it may get even higher and more stable with proper voltage controls. Right now we only have about a 20% overclock at 1.78GHz so the device should be able to handle a little more stress than we're giving it.

Thanks so much for all your work, and for thinking of those of us still on CM9.
Is there an easy flashable (or pushable) implementation for the lower power draw, that could be applied by us to the nightly builds? Last I heard, the fix was not yet added to the nightlies.

Extract the boot.img from jcsullins zip. Take the latest nightly and unzip (when it asks to replace the terminfo stuff, select "no" or "no to all"). Delete the boot.img file in the unzipped nightly. Copy the jcsullins boot.img in its place (you can try copying mine if you want, but it may not boot). Rezip the files and flash.

Ahh, so essentially a kernel swap? I was unaware the power fixes were solely located here.
Thanks, will try.

1.5GHz is the TouchPad's true 'factory maximum CPU clock speed'. Who knows what its "true capacity" is. Many devices with very good SoCs have an overclock threshold of about 30-50% and it may get even higher and more stable with proper voltage controls. Right now we only have about a 20% overclock at 1.78GHz so the device should be able to handle a little more stress than we're giving it.

I heard that a touchpad with a good SoC could OC to 2.4 Ghz if we had a proper kernel.
[UPDATE]New Upload
I've uploaded a kernel with CPU overclock to 2157MHz and GPU overclocked at 320MHz. Enjoy.
this was many months ago but i seem to recall that -sga- mentioned he saw no performance gains past a certain point. i think it was 1.7ghz but since it was a while back i don't really recall the exact number. or maybe he said diminishing returns past a certain point.
edit: i found his post about it http://forum.xda-developers.com/showpost.php?p=33883333&postcount=53
maybe he was talking about the ability to o/c past 1.7 was more difficult and not in regards to the performance gains?
HAH!
Flashed this!
in a fraction second by one after one the processes SystemUI And com.process.android.phone is Stopping.
I can't even use a single app.
using SCHIZOID 2.00 JB 4.2.2
plz help
This is a very simple guide to increase performance in Oxygen os (any version) for those of you who are sick of the lagfest sometimes experienced in OOS (i know i am). Many people just flash a custom kernel, which is a good way to fix performance. For those of you who dont want to mess around with flashing kernels (and are rooted), just download kernel adiutor (https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=pt_PT) from play store and edit the values to these ones:
- Open kernel adiutor, give it root access, and go into cpu section and do the following changes:
Change MAX cpu freq to 1958Mhz.
Scroll down to the end and change input boost from 960Mhz to 1497Mhz.
Make sure interactive governor is selected and go into governor settings.
Change the following parameters:
Above_hispeed_delay: 20000 1400000:40000 1700000:20000
Hispeed_freq: 1190400
min_sample_time: 80000
sampling_down_factor: 0
target_loads: 85 300000:40 700000:45 900000:55 1200000:65 1500000:75
Dont forget to hit apply at boot on the cpu section of kernel adiutor, otherwise once you reboot it will revert back all the changes you made
Changed first post based on experimentation and better results with the above settings
Dear xda community
Following on from the work done to date in the active community in the head-fi.org forum, I have decided to post this work on xda to share the work done so far and, well, also elicit help from the best technical community I've spoken to in the past. This thread will solely focus on the RK3188-based FiiO X5iii player, and will thus contain any and all software modifications to the FiiO X5iii. The custom kernel contains the largest amount of new code, extra features and performance improvements for the X5, and really pushes the limits of the hardware to its fullest potential. The benchmarks alone are outstanding - using Geekbench and Antutu the performance is more than 400% that of the current vanilla firmware, and it will similarly feel more intuitive and responsive, as can be attested by the numerous users to date.
As of Version 3.x, audio tuning is also taken one step further. A new custom AK4490 driver has been implemented, and a significant portion of the redundant and/or unnecessary code has been removed from the sound drivers. Therefore, if not better, the sound should at least feel ‘cleaner’ when compared with previous or vanilla versions. We still have a long way to go to enhance the audio on these DACs, but this driver is a start.
Installation instructions are outlined further below; ie flash via TWRP, but first-time users can also find a more detailed set of instructions in the zip file.
There are three versions - the 2GHz version for faster CPUs, the 1.7GHz for most players, and the 1.4GHz version for anyone experiencing random lockups or reboots.
Unique Features
- Custom AK4490 DAC driver (faster, better oversampling)
- Support for DSD256
- Increased clock speed from 1416MHz to 2016MHz
- Increased GPU speed from 133MHz to 600MHz
- Increased DDR speed from 200MHz to 800MHz
- Better voltage regulation using all possible pwm and clocks on the board
- Increased available RAM by 20%
- LZ4 compression for better, faster swap and virtual memory usage
- ZRAM usage for additional system memory
- Fsync_disable for much faster system processing
- UKSM for faster Kernel operations
- Adaptive-LMK for better memory management
- Undervolting for lower heat dissipation and battery consumption
- New Faster CPU Governors: interactiveX, PegasusQ,
- New Faster I/O Schedulers: zen, bfq, sio, vr, maple
- New Faster Westwood TCP/IP congestion handler for faster wifi and internet access
- CPUBoost algorithm for faster on-demand processing
- CPU SMP feature for powering down unused cores on screen off
- RQ Affinity for faster I/O scheduling
- Linaro gcc toolkit for faster, leaner code
- RK3188 neon vfp3 code optimisation for faster fixed-point and floating DSP operation
- Full init.d support for script runtime loading
- Frandom genrator (23x faster than standard random function)

Installation instructions
1) Windows and/or first-time users
If you already have TWRP or a previous version of my kernel, go to step 2.
a) If you don't yet have TWRP and/or any previous version of my kernel yet, download the Windows-based loader here and unzip to a folder
https://www.androidfilehost.com/?fid=1395089523397899882
(note: you need to have the FiiO USB Windows drivers correctly installed)
b) Run the AndroidTool.exe program and connect the FiiO via USB.
c) Put the player in bootloader mode (just as if you were going to upgrade the player the traditional FiiO way with the Windows based loader), by pressing power+pause+back.
d) If all goes well you should see the green light with 'Found One Loader Device'. Make sure 'boot' and 'recovery_twrp' are selected and press Run. Once done, click the 'Advanced Function' tab and click Reset Device. You should have the new kernel and TWRP installed!
2) TWRP users
a) Download the latest version of the kernel (with new optimisation scripts) above and push to sdcard
b) Reboot to TWRP recovery
c) Install -> FiiO-X5iii-jkbuha-V3.1-TWRP.zip
d) Wipe kernel and dalvik cache
e) Reboot
f) IMPORTANT: leave running for new scripts to do their magic (you will be prompted to reboot)
g) Reboot
h) Enjoy

Version 3.11 released, containing miscellaneous bugfixes
hello
thanks for this release. very useful
Version 3.31 released, containing new performance-enhancing features, bug fixes and new improvements.
Thanks a lot for your work, jkbuha. Some friends also have the Fiio X5 iii and they all use your Kernel now. The Player is much smoother and faster.
I use the 1704 MHz version. For me its the best compromise of speed and battery lifetime.
With the 2016 MHz version my player gets very hot. Does your player also generate so much heat with this version?

Thanks for the feedback. The 2016 version uses slightly higher voltages than the default FiiO kernel at 1416MHz, but it's never generated any noticeable heat; at least in my case. Just to be safe, if you continue to experience heating, I'd use the 1704Mhz; other than benchmark scores the daily usage experience is the same as 2016MHz.
Dear jkbuha,
Although using XDA forum a long time, just signed up because I really needed to say thanks. While I was satsified with sound quality on my X5, the performance of the device and general bugs left A LOT to desire.
Just flashed your kernel onto a stock 1.2.5 rom and the performance so far is outstanding. The X5 never worked THAT snappy. This is extraordinary work, sir, hats off. FIIO should buy this from you and put in their next release. Seriously.
I'll be spending the next days testing the battery performance with the hopes of getting better idle battery life, which bother the bejesus out of me.
Anyway, thanks again, your work is very appreciated!

Hi I just order my fiio x5iii generation and im looking into TWRP, Root, and I want to install viper4android into the latest firmware if possible because I heard they got rid of it. I see your program to install TWRP and the kernel but what about rooting do you know if Magisk or Supersu will root and is viper4android able to be installed? I would really appreciate any help. Thank You I look forward to using your Kernel and TWRP. Should I stay on the first firmware also. My main goal is viper4android 2.3.4 with high quality driver and magisk if possible.

Hi, Im new to fiio x5iii player but ive rooted and flashed tons of android phones. Im getting lost in all the directions online. If I have a brand new never updated fiio x5 player how would you recommend going about things? Should I flash TWRP and the kernel without updating the firmware? Im trying to get Twrp, Root, Kernel, and Viper4android 2.3.4 installed I know the fiio music has some viper options you have to pay for but id rather get all of them with 2.3.4 installed.
I would really appreciate some help. I've never used a high resolution player. I've rooted a dozen Androids and I know they can all have differences so that's why I'm curious.
Here's my plan
Install twrp from the 2.6 windows zip on stock firmware that's on it when I get it.
Make a backup
Flash SuperSU
Make another backup with root.
Install viper4 Android apk not zip
Install BusyBox
If there's some specific firmware I should be on for twrp to flash properly I would like to know.
If I want to upgrade firmware do I need to reinstall stock recovery or can I just update it using the update tool?

Sounds like the /system partition didn't mount properly or you're out of free space. Try and mount it manually in TWRP and see if you can free some space and/or run the installer again

Yes that approach is correct (the custom kernel also includes busybox so that last step is redundant). However V4A doesn't work system-wide on any FiiO firmware; you'd need to play around with the audio_policy.conf to make it work, and if you do I'd be happy to integrate your work into the latest kernel as an option install. Just be mindful of the loss in audio fidelity; you'd probably be better off using Neutron as I've explained on the head-fi forum.
TWRP works on all FiiO firmwares. For audiophiles, the recommended firmware is 1.2.3 (latest is 1.2.5) as the audio libraries seem to be the best though you can select which library you want in the custom kernel installer.
To upgrade firmware you need to install stock recovery. FiiO's update tool doesn't work with TWRP, which is understandable.

Awesome I cant wait to get started. Its sounds like the fiio is pretty good for rooting and modding. If I can just install twrp and then if I want to update later use your tool to reinstall stock recovery to update it sounds pretty good.
If I can get viper to work ill let everyone know. Its fine if I lose fidelity a little for one backup then ill keep one with stock to go back to if I want.

How does viper effects sound in the fiio music app? I've installed it on my phone and it's weird no music will play on it. I see that it has every setting I like except for headphone surround sound. My favorite settings are gain , clarity, dynamic system or bass but usually dynamic system, and headphone surround sound is all I need anyway. Wonder why they didn't include that. I also don't understand how it'll know you paid for the settings if you uninstall it or flash a new firmware. I paid for 2 day shipping and it hasn't even shipped yet cause of the holidays I can't wait.

FiiO Music is hard wired to play only on FiiO Players. Which of course is understandable. I'm sure someone could figure out to hack it if it's really worthwhile...
Viper on FiiO Music sounds the same as you'd expect on other players

Thats what i thought that the fiio app is probably hackable and if someone could do so its possible it would play on all androids without root maybe. Do you have a copy of the stock kernel by itself unrooted? I like to have a clean copy of everything. Also after flashing twrp and kernel what does "reset device" do does it go into twrp or reboot and wipe device?
I found a stock firmware 1.1.0 and got the boot img out of that. I cant find a firmware for 1.0.9 on fiios firmware its just a pdf manual and it says 1.0.9 but it isnt or purist rom 1.0.9 has been removed from all the links.

I dont know if you guys know it but poweramp and neutron play DSD files on android. Matter of fact they play the top 256 no problem. This is new to me so im not sure if its the same. 512 is only on 5 songs so thats not necessary and 1024 doesn't exist yet.
