[KERNEL][YP-G1][MTD][3.0.101][Linaro] Impulse r7.1 (26/06/14)

Hi, I wanted to try something for the Galaxy Player 4.0. I know that the hummingbird processor inside of it had a lot of potential and I want to extract all the power it has to offer . To do so I had to use any tools that could help me achieve that objective . Now enough with the talk and more with the actual content of this kernel. Note that this kernel works for both versions (US and Intl, Korea can work but it hasn't been tested).

Disclaimer: This is a MTD kernel, it will only work with CM based ROMS (CM10.1 and up). Flashing it in a GB ROM could result in a brick, Also I'm not responsible to any bricks caused by this kernel.

Features:
Linux 3.0.101
Compiled it using Christopher83 custom Linaro 4.7.4 toolchain optimised for Cortex-A8 chipsets (4.9.1 For Android 4.4 and up)
Cranked it up with -O3 optimisations and -Ofast optimsations for GPU
LZ4 Compression for kernel and crypto
OC available up to 1.2 GHz (through 100 MHz steps)
Available governors (8): Lulzactive, SmartassV2 Intellidemand, Conservative, Ondemand, Interactive, Userspace and Powersave.
Available I/O schedulers (5): Noop, Deadline, Fiops, Row, Cfq, Sioplus, Bfq (Row is enabled by default)
Updated GPU drivers (1.8@2198402 )
Tweaked and optimised I/O schedulers
Sound improvements (ALSA, PCM)
ARM RWSEM optimisations
Optimised SLUB memory allocator
Timer slack controller support
Backported CPUidle from 3.5 kernel
Support for swap
CIFS
TUN
Zram
Ext4 optimisations
Fast Charge
Fast wifi while in standby
Support for OTG connectivity
NTFS and FAT read and write support
Undervolted the LCD panel by 20%
LMK backported from kernel 3.4
Minimum brightness lowered (Needs confirmation)
Always up-to-date with Bbelos and Cyanogenmod Aries sources
720p Video recording support

Installation:
Flash the zip with CWM. (Yes it's that simple )

Note: with the newer version of CWM, you'll need to flash the zip from the internal sdcard ONLY. If you want to use the external sdcard to flash the zip, please mount the internal one first as it will cause your device to be stuck in the samsung logo.

r6 (18/04/14)
Synced with the *regular* aries repo
Compiled with the newer 2014-01 Christopher83's toolchain
Removed 1.3 and 1.4 GHZ OC for stability purposes, however I added 1.1 GHZ if you needed it.
Added the BFQ I/O Scheduler
Added support for the 720p video recording as well as some fixes for preview
Misc optimisations.

r5 (17/01/14)
Android 4.4 support (KitKat)
Stuff synced from the dev repo as well (Front cam fix, lvm etc...)
Changed some optimisation flags
Optimised with newer 2013-12 Christopher83 toolchain

Fixed the rotation (for the camera)
Misc fixes

r4.5 (12/12/13)
Updated to Linux 3.0.101

Included the fix for newer CM and Pac-Man Roms
Updated to the 11/13 toolchain from Christopher89

r4 (14/10/13):
Upstream changes from bbelos and aries tree (resized the /system and /cache partition)
Added 1.1 and 1.3 GHZ OC steps
Backported Cpuidle from 3.5 (not deep idle as it's been reported that it causes stability issues)
Updated the GPU drivers to 1.8@2198402

Digital FM radio works, which does sound better than the salsa method.

Bottom speaker still sounds quieter.

How fast is fast charge?

I don't know how much time it takes for fast charge. Actually fast charge is only something that makes your device think that you're using AC when you charge with your computer. And I still yet implemented it.

as a future feature could you force enable adb? otherwise porting roms is impossible because I can't get a bootloop logcat

I don't know well as far as the 4.2.2 kernel related, adb needs to be enabled from the dev section (because of security reasons) except for the first boot where it is doing an initial logcat than lock itself. I can try to do something though.

Awesome work! I will flash it this weekend
I'm still in 4.1 though can i just flash it or do i need to do it from the start?
And what are features like CIFS and TUN?

Click to expand...

Click to collapse

It can work but I'm not giving support for it. Also cifs is known for mostly remote file access and tun for vps servers.

Great work on this! I have one suggestion though. Can the amount of available ram be increased? I know the kernels on the 5.0 have done it, so I don't see why it would not be possible on the 4.0 (and everyone loves more ram!).

I would need to find the right amount of ram that the camera needs (which could take some time).

Base on others sources

I can't use the same amount of ram as the 5.0 because it will crash the camera, I will try to put 10000 instead of 14000.

I ment sources of kernels for different devices using same soc as yours

Hmm well I checked venturi and derteufel sources, no good. I'll check p1 and Crespo later.


Hey guys I'm considering this, would you like to get TWRP instead of CWM as far as the recovery solution goes?

Ok I put up the pool in OP, as for aroma FM, I don't want to mess with including touchscreen drivers (I feel sometime too lazy I know )
