[DISCONTINUED][Kernel][CM7/MIUI] Platypus (6/27) Voodoo, OC/UV

changelog (Neo 10):
- [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

Changelog (from NEO_06):


characteristics:
- conservative governor (screen: on & off)
- touchkey timeout (no led-notifcation) | led-notification (2nd kernel)
- some more battery savings & speed-ups
- OC up to 1.6 GHz (but it seems the power-saving measures don't let it scale up performance correctly - so max frequency recommended is 1.4 GHz)
- 339 MB (that's nearly 340 MB of RAM !)
- Juwe11's OOM killer settings
- tweaked memory settings & stuff (too much to remember what all was changed)
- disabled logcat & printk output [thanks to existz for ideas !] -> battery savings & less overhead

- new kernel base (teamhacksung / upstream vanilla source)
- stock toolchain (for now - all other toolchains lead to kernel panic)

(from quorra r10)

- Voodoo Sound v9
- old bluetooth settings (provided I didn't forget anything)
- less aggressive conservative governor (when screen is off - 15% steps instead of 50%)

- re-added BNEP & HIDP bluetooth support
- reverted new optimization flags
- changes in cpu scheduler settings to behave better [need feedback]

- compiled in the iptables modules INTO THE KERNEL (module loading has issues ?)
- reverted new optimization flags re-added them: need testing for call drops & any instabilities
- [upstream] gpio fixes & cleanups (potential additional battery drain fixes) [thanks codeworkx !]

- changes in cpu scheduler settings to behave better [need feedback] seems like this leads to reboots while calling again for some of you - disabling it should fix it - please test & report


- (re-added) changes in cpu scheduler settings to behave better [need feedback, no reboots here] (false positive report of reboots)
- new conservative governor thresholds & sampling rate for while screen is off [need feedback]
- mlock [pt1/2] fix from newer kernels: this should reduce some lags significantly during heavy i/o and/or wakeup
- complete optimization flags for the kernel (add them to AFLAGS, too)
- Nick Piggin inode integrity fixes (2 of those: fsync race fix, barrier fix) [data safety & hangs during write]
- undo disabling of Bluetooth power_save feature; added bt_power, fix that mode & fix a compilation issue with it (potential additional power savings during Bluetooth usage)
- [testing] support for Apple Wireless keyboard & other wireless stuff

- [upstream] migration to MTD layout & upstream CM7 handling (thanks to atinm & koush !)
- [upstream] s3cfb fix: no issues with screen output anymore before lock & unlock (thanks codeworkx !) [afaik RIL Polling still needs to be resolved]
- [upstream] headset cleanup
- [upstream] settings for stock headset, fixes skipping music
- [upstream + changes] disable PMEM for SGS, Cappy & Vibrant
- [upstream] samsung_modemctl: add aries modemctl (thanks to coolya !)
- add nofail variants of kmalloc kcalloc kzalloc (less drama & looping with filesystems - so (potentially) more battery savings & saved cpu cycles)
- add an improved memcopy & memmove implementation for more speed & performance (testing)
- much changes in screenstate_scaling script:

(from quorra r9)

- enabled support for [external] SD-card suspend (battery savings) - make sure you don't have files on external SD in use when you use it for longer periods and want to save some additional energy
- additional optimization flags for improved overall speed & NEON (multimedia) usage (tested on fascinate & Nexus S - so should be somewhat stable & proven)
- several small fixes & adjustments in the config
- re-enabled kernel error messages for better bug diagnosis & troubleshooting [practically no overhead]
- iptables - built as modules; full iptables support for ipv4 & ipv6 now
- [EXPERIMENTAL] higher charging temperatures (values from GB Samsung source + lower low recovery settings) [especially useful in warmer regions & the summer]
- [testing] add support for Apple Wireless keyboard and other wireless stuff
- enabled more BT options & settings
- CFS scheduler fix with load weight calculation (potentially fixing issues & allowing to safe more battery juice)

- [upstream] some fixes for initial installation (not applicable here since not used for initial kernel installation)

(from quorra r8)

- kernel comes pre-packaged with smartass governor
- [EXPERIMENTAL] - make an nandroid backup before testing & using: for switching to other governor (while screen is on - screen off = conservative) apply additional "screenstate_scaling switcher" script

# see attachments#, # additional scripts# <-- *Link* inside

- added interactiveX cpufreq governor from leanKernel-tbolt/imoseyon (adds sleep & wake code) - (probably) better (less) battery usage than conventional interactive governor [need feedback]
- tweaked interactive governor to scale down to lower frequencies faster (less battery usage & still very smooth)
- fixed & tweaked SavagedZen [*very* laggy - for those battery runtime fetishists ^^] [needs more testing & feedback]

- [upstream] wifi driver now supports channel 12, 13 and 14 again (thanks to atinm !)
- [upstream] added recovery 2e checks for initial update
- [upstream] accurate battery gauge display (thanks to atinm !)
- [upstream] improvements in recovery-handling with the /cache partition (thanks codeworkx !)

- [upstream] some fixes & improvements for recovery (e.g. creating missing devicenodes)

• Enable auto rotation on your old kernel before flashing.
• check if auto-rotation works - (is it enabled ?) - if not press power button 10+ seconds (ignore power menu popping up).

• Wipe cache/dalvik cache
• Reflash kernel
• See this post or this one (5/11 only). Thanks mcord11758!!

Voodoo Color settings:

Q: I don't have that nice ice-ish white color on my screen anymore - you suck !

Q: my screen looks like someone pissed on the screen - you suck !

(sorry for the language ^^)

A: I love you too ^^
download Voodoo Control or Voodoo Control Plus

Screen RGB multipliers:

- Red: 321*
- Green: 321*
- Blue: 429*

Screen v1 gamma hack:

- use Alt. settings

- or if you prefer others - use: "Reset to 2.3.3 defaults", "Punchy settings" (punchy could lead to a great screen while locking the screen and having "screen off" animation disabled)

- WIFI & stuff not working ?

lippui94 cleaning script, then wipe dalvik, then fix permissions, then kernel - eventuall governor switch - , then wipe dalvik, then wipe cache, then fix permission

- reboots during calling ?

please report ASAP !

this is supposed to be fixed & a non-issue

- Radio (phone function) not working ?

this only works with nightlys > #14 and up

- phone is not as smooth as with previous kernel releases

yeah - sorry, might be due to the fact that I'm forced to use stock toolchain (less optimizations)

Just want to say when doing the LED notification fix using root explorer, make sure to change the permissions or CM7 settings will force close on you. Should be set to rw-r--r--

Odd, can't get the LED notifications to work...hmmm. I assume this is for the bottom lights, correct? Do I need to have the BLN app installed and configured or turn it off? Tried to do the "test LED now" or whatever in the options and nothing happens.

Maybe i'm setting it up wrong or something. What are the permissions supposed to be for the APK file? I have it set to rw-r--r--, same as all the other apps in the system/app folder. I even tried setting up the text message one, sent myself a text but all it does is illuminate the keys, no flashing, no different color. Kinda stumped.

hi, i wanted to know if this kernel i working fine for you guys, im trying to find a new kernel that help me save battery, i saw that this kernel work with that issue, i wanted to ask you guys, if you are seeing better battery usage, im using the the escapist's kernel.
