Default [FW 402][UB][6502/6503]YadliKernel, almost stock, slight undervolt, notification light mod

This kernel is based on Sony .402 source.
The goal is to create an almost stock kernel with recovery, battery saving modules, and eye-candies.

Attention: Users with locked boot loader should NOT flash this, even you have recovery!
The image will be written to the correct partition, but the BL will refuse to load it!


Credits goes to @DoomLord for his wonderful guide, toolchain and various tools for kernel building.

Features:
  • -75mv undervolt. No sysfs interface. Taking effect from powering on.
  • Notification light mod. Discussion thread [v2]
  • A new patch to correctly cap all cores. Compatible with all frequency setting apps. [v3]

TODOs:
  • Nothing TODO. Any suggestions?

YadliKernelV3 pre-built image download
YadliKernelV2 pre-built image download

Hey mate, very nice to have another developer for Z2.
It is just my opinion, but isn't -75mv will create unstable system?

I'm testing this all the time. Seems no problem so far.
I do experience random reboots one or two times a day with -100mv for my phone.
If you find it unstable, please post it here and I'll modify the parameters.
(Well in that case I think I'd better plug the undervolt interface back in )

If you are talking about .438 (is it 438 or 437? I'm not sure ), then perhaps no.
Please wait until the source code for that firmware to be released by Sony.

I have a locked bootloader, but rooted (stock. 402) and using XZDualRecovery. Can I simply flash this kernel?

In that thread, some user experience crashes beyond -12mv.

Just for your consideration

I'm guessing this won't work on a locked bootloader (when has it ever?)
If I've ever been of any assistance, just press the THANKS button

Thanks! I'll consider changing the initial values, or bring in the interface in the next version.
Meanwhile, a lot of people are testing this in a Chinese forum (I guess they're going for the LED mod not the unstable undervolt). If any of them report crashes I'll update at once.

Also, in the next version I'll write a patch similar to "snake charmer" but works without FauxClock.
Thus you can cap the freqs with things like SetCPU.

I personally purchased both but FauxClock refuses to work without Google stuff.
And now I'm on a Chinese FW... Well
