SGS edition of the Platypus Revolutions kernel

This Project is inactive/low activity for a longer period of time






Kernel

CM7 & MIUI only


NEO series

(since May 24th '11)


(thanks to Tk for the layout idea )




before you ask for any ETAs:


The first rule of CyanogenMod [and this project]: DO NOT ASK FOR AN ETA!


---------------------------------------------------------------------------------------


First step before install & kernel switch:

Always have this cleaning script on your internal SD card ready


If you're
- switching kernels,
- have issues with auto-rotation,
- the cam,
- bootloops
- want to remove init script
- recover from a failed overclock attempt

please give either:

- lippol94's updated cleaning script (apply via CWM recovery): http://www.multiupload.com/XFH1GCK4MB

or

- WiwiPouPou's SYSTEM CLEANER SCRIPT (also apply via CWM recovery): (http://xdaforums.com/showpost.php?p=14805606&postcount=21739)

a try


the kernel already applies some cleaning steps during install but sometimes that's not enough ...

Introduction:



Hi guys,

this is my first modded kernel for the SGS (CM7/MIUI only)

I first needed to test it to make sure that it'll be stable & boot at the first place

so far it's very fast & responsive & smooth


This thread shall serve as the center for my testing kernels (stability & functionality-wise)


DISCLAIMER: the kernel (binary) and driver modules are provided as is. If problems occcur they most probably are from upstream and can be fixed with the newest version. Since I'm doing this in my free spare time as a hobby (quenching my thirst for tweaks & performance) updates will occur irregularly as time permits and I see fit (most probably when new features & bugfixes arrive). YOU are responsible for the actions that you take (such as over- or underclocking), etc. You agree that I can not be held liable for any potential damage that arises from your actions in combination with or the usage of this kernel and other related parts.

Kudos:
* Google, Andy Rubin & the whole Android crew
* Linus Torvalds & the kernel hackers for upstream Linux
* cyanogen & all the devs out there hacking on this
* Supercurio for enriching our media experience of this smartphone
* codeworkx, coolya, guiper, atinm - the whole teamhacksung|cmsgsteam crew and all other hackers working on CM7
* laststufo, hardcore, nikademus, existz and all the other kernel hackers on the SGS forum
* zen-kernel team for inspiration to create a kernel, too
* all other contributors (devs, users, etc.) who make this possible


The purpose of these kernels is extensive stability testing addressing the following sticking points:
- overall stability & functioning of the kernel and phone
- call drops, missed calls, etc.
- lags (suggestions for improvements are welcome)
- auto-rotation, sensors, etc.
- Voodoo Control Plus [any crashes ? compatibility problems ?]
- working on CM7 or MIUI ?
- scheduler, sound, video synchronisation & lags: Tap Tap Revenge 4 (especially at the beginning of songs)
- scheduler, sound, video synchronisation and any other issues: doodle dash (while shooting & sound activated)
- proper pmem memory layout & settings: proper functioning of Google Googles

current UV & OC stable values:

Recommended apps for OC/UV:

- Pimp my CPU (also available here on XDA for those who don't have a credit card, etc.)

- Xan's VoltageControl


on stability testing:

http://xdaforums.com/showpost.php?p=13255871&postcount=5

(start with "Q: I'm new in OC/OV operations so please could you explain to me how to set it in the best way?")


the following OC/UV values are only applicable for kernels with the old OC/UV implementation (max. 1.3 GHz)

my current UV (undervolt) stable Values :

old OC/UV implementation (morfic, bilboa1/kang, TheEscapist):

1300000 0 (haven't tested 1.3 GHz much yet)
1200000 -25
1000000 -50
800000 -75
600000 -100
400000 -100
200000 -125
100000 -150



edit:

1200000 -50
1000000 -75
800000 -75
600000 -225
400000 -125
200000 -150
100000 -175

thanks jetcz !


new OC/UV implementation (morfic, bilboa1/kang, TheEscapist - Tk-Glitch):

Tk-Glitch said:

Note that these UV settings will be unstable on many devices. It's only informative.

1600 MHz - 1.500v / -> That's high and many devices will fail on this frequency. Find working UV for you if any.
1500 MHz - 1.500v / -> That's high and many devices will fail on this frequency. Find working UV for you if any.
1440 MHz - 1.475v / -75mv
1400 MHz - 1.450v / -75mv
1300 MHz - 1.400v / -75mv
1200 MHz - 1.350v / -75mv
1000 MHz - 1.250v / -50mv - If you have stability issues, try to let this one by default.
800 MHz - 1.200v / -75mv
400 MHz - 1.050v / -100mv
200 MHz - 0.950v / -150mv
100 MHz - 0.950v / -200mv - (can be very different between two devices)

More volts is not always equal to more stability. Try to add more UV (less volts) if the frequency you're trying to achieve is unstable.
Considering all phones will respond differently to OC/UV, to tweak the values to suit your device will be required.

By default, no overclock/undervolt is applied. You'll need to use one of the tools below to adjust the frequencies and voltages.
Note : Never ever use SetCPU with this kernel. You could encounter many stability problems like random reboots or bootloops.

hope that answers at least part of your questions


once I find some time again and/or other devs join in the tweaking of Deep Idle

there probably will be more refinements & tweaks to the implementation which was originally included by Samsung in the GB kernel source

due to lack of time & serving several devices at once:

Changelog said:

BIG FAT WARNING:

currently for some the installation seems to reset contacts & system state
(and thus deletes e.g. emails)

so make sure YOU BACKUP BEFORE YOU INSTALL this kernel !

(which is generally a good idea with installing kernels & ROMs)


Recommended INSTALLATION PROCEDURE (when switching to Neo/Platypus kernels):

1) backup your data
2) install kernel + reboot into recovery (so that you're running recovery with new kernel)
3) format /system + factory reset
4) re-flash ROM + re-flash kernel [without re-booting in between]
5) reboot - now you can restore data [if restoring a nandroid - don't forgot to re-flash the kernel
in the same session while still in cwm recovery without reboot in between]



NEO 17 (r18 - codename Butterfly) changelog [SGS/Telus, Captivate, Vibrant]

Changes (from r16 [r17 - intermediate BLN build]):

• corrected voodoo FM radio enhancements only to depend on SGS/Telus build
• usb battery drain fix (thx to farmatito)
• quiet binder error messages in dmesg - useless for productivity builds
• optimized checksum library
• added: 600 MHz step
• bumped 1000 MHz (1 GHz) by +25 mV [equals samsung kernel stock voltage]
• bumped system_tweak init-script to V63 (now similar to the one used on Neo XX)
• bumped toolchain to 4.5 09/2011
• fix memory-leak on dma-mapping (thx to existz for the idea !)
• fix data loss/corruption with bad microSD cards by raising write timeout
• optimize re-claiming: faster re-initialization of removed microSD
• put microSD before attempting to suspend
• vfs_cache_pressure up to 50 (less lags & lower battery consumption ?)
• some minor cypress (softkey) driver fixes (thanks to pawitp !)
• slightly raised readahead
• delay subsequent suspend attempts after non-successful prior attempts (save battery + reduce cpu load)
• TCP increase default initial receive window + congestion window to 10
• pm: fix enable ordering in resume
• synced with nightly #143/144

attached you'll find test-builds with deep-idle support enabled (cpu only) so Gingerbread bootloaders are imperative

please give feedback if you encounter any instabilities, SODs, etc.

if you run into any -

1) please remove system/etc/init.d/S98system_tweak first [& re-flash kernel with the init-script removed from the zip install-package]

2) then test again if it's stable afterwards


thanks & enjoy !

changelog:
- [probably] some more battery savings & speed-ups
- (complete ?) update/backport of the updated pl330 dma driver from samsung GB source [(probably) more performance, less power consumption]
- shorter kernel-package name on user demand (due to readability issues in CWM recovery)


NEW:
- bluetooth HID driver port from Samsung GB source (how to use this functionality ? probably less battery consumption - the more correct/complete drivers included - the more stuff can be sent to powersave)

- synced with upstream: 7.1.0-RC1 / nightly #40 (SGS numbering scheme)
- upstream additions: Hack a mute/unmute for Vibrant
- upstream: another variant of sleep/hang of death (probably also resolved)

- wifi + data networking issues resolved





- galaxysmtd [repo synced against ~#40 / 7.1.0 RC1] tested on 7.1.0-RC1, captivatemtd [-> #41] , vibrantmtd [-> #37]






testing/need feedback:
- stability / reboots [it uses some new optimization-flags so I need to know if those affect stability]
- any regressions with games, apps, etc. ? [none known so far]
- battery runtime


Troubleshooting and other stuff:

other governors:

hopefully the explanations in S98screenstate_scaling should be detailed enough to let you change to a different governor

if not let me know and I'll see if I can come up with a package with different script-variations to replace the scripts in the kernel-package
