[KERNEL] [L-preview LPX13D] [Code_Blue r1196-L]

[eng.stk]

Hi guys! Here comes the first custom kernel in xda for L-preview

I'm presenting my personal kernel Code_Blue, that started as an addon for Purity ROM, called Purified Kernel.
Some of you that know me from other Nexus devices asked me to bring back the project, so I (finally) did.
My releases are Dragon_Shield powered and I'm going to share them with you.

All I want is full smoothness, performance and battery on my hammerhead, so I build always with Linaro optimized Cortex A15 toolchains.
This time I aim for a "stockish" feel lean build and for stability purposes I will stay with GCC 4.9.2 for now.
Code is based of android-msm-hammerhead-3.4-l-preview, forked from android/kernel_msm.
Useful and powerful picks are mandatory

Be sure to join Code_Blue users G+ community
You keep the spirit alive!


Kernel features:

• Build on Ubuntu 14.04.1 x86_64 (Dragon_Shield VPS @ www.servercore.com.br - thanks @ChristianLetti)

• Full -Ofast+graphite support with device and target flags enhanced, linaro build improvements, etc
• Based on android-msm-hammerhead-3.4-l-preview + own commits & cherry-picks on demand from several top devs, code aurora, linaro...

• Removed some debug and logging options
• Enhanced performance and battery patches
• Several CPU Governors (blu_active own governor is default)
• Voltage Control UV_mV_table by @franciscofranco (UV down to 700mV possible)
• Enhanced TCP methods (westwood is default)
• Network and Wifi tweaks
• Several I/O control (FIOPS is default)
• Removed stock mpdecision and thermald
• blu_plug: Dynamic hotplug for hammerhead (based in dyn_hotplug from @stratosk), with screenoff battery saving (max_freq 1190400 @ max dual core)
• powersaver_mode available (switch usefull on light tasks, set max_freq 1728 MHz @ single core)
• L msm_thermal by @franciscofranco
• Optimized RWSEM, AES and SHA1 routines
• Vibrator Strength tunable (60% default)

• USB Fast Charge (USB mode up to 900mA with MTP, by @flar2), Increase battery charging current to use higher input current (on AC mode by @faux123), proprietary charger detection
• init.d support (busybox run-parts required)

Download latest Code_Blue Kernel zip on Test folder, flash in recovery and profit :highfive:
No mirrors allowed. Don't post hardlinks, use original links.
Changelog is available @ website also.


Builds are coded as follows:

• test only for now on tests folder, no changelog, build with Linaro Cortex-A15 4.9.2 to minimize issues in troubleshoot.

Warning: If you come from other kernel, you should dirty flash your ROM before flashing Code_Blue zip to avoid problems.
Reflash ROM -> flash SuperSU -> Boot device -> flash Code_Blue.
Also uninstall or clean data of any kernel control app you're using.

So who's going to be the brave user and try this? I'm surprised to see a custom kernel already for Preview L! Kernel source has already been released? i haven't been following

Glad there's a kernel out! So thanks! . but Max CPU is stuck at 1574400. If i change to Max it just goes back down after hitting apply?

What app are you using to control the frequencies?

What app are you using to control the frequencies?

Trickstermod.

"set on boot" is selected? Also you might have to copy some cpu.sh files if nothing else works

now it just right .sheduler row en governor ondemand and cpufrequentie is on.

Great! I think every Kernel management app isn't going to be compatible with every kernel and vice versa without messing around with a couple of options

 

[suprstar29]

I don't know if it is just me, but faux sound doesn't seem to be working. App starts up and says that the kernel is supported, but messing around with the toggles doesn't cause anything to happen. I'm assuming that the app or patch needs to be updated to work with L, or I'm just stupid and an not doing something right.

I didn't think it was.

I didn't think it was.

That's what I thought. When it comes to XDA and the developers of the Open Source world, anything is possible! .. Just flashed it and its running nice so far.
