Flashing Instructions:
Flash the zip with TWRP. I recommend making a nandroid backup before flashing. This kernel will work on both the stock ROM and custom ROMs that have WiFi configured as a kernel module.

Initial Build Up
The first ever custom kernel for the Moto X Play is now available!
The kernel includes everything mentioned above. It includes notification LED support, and the notification LED will start working on the stock ROM after flashing this kernel. It does not include IntelliPlug or Lionfish, as they are incompatible with big.LITTLE systems in their present state.
I have tested the core functionality and everything appears to work. However, since this is a very early release, I would not be surprised if bugs exist. Please report any bugs or crashes you encounter.
Since everything appears to work in this kernel, we are all set for a CyanogenMod port. Tomorrow, I plan to start porting CM12.1 to this device. If you're lucky, you might be seeing a fully working CM build by tomorrow night.

---

Mate you freakin legend. That's some quick development support for our battery beast. I'm working too long hours to test this just now if I get chance on a break I'll get twrp installed etc my device is only rooted so far.
Noticed you brought cm12 to osprey as well. Do you have a donations link as I'd like to donate a little when I get paid just as a thank you.

So far haven't noticed any performance improvements (still fresh) but I am LOVING this notification light!!! I can finally at a quick glance tell if it's worth reaching for my phone. And at night, I know where it is. You're awesome! Definitely need a donate link ..

Firstly thanks for working on the X Play. Installed fine but Moto Voice now not working? Cannot switch on in Moto app, was fine prior to flashing this kernel?

I just checked and can confirm that the kernel breaks audio input for Moto Voice. The microphone works fine everywhere else though. There is probably a small change Motorola made to the audio path for always listening audio between the osprey and lux kernels, or it might have been broken by a CodeAurora change. I'll do some more investigating when I get time.

Deep sleep issues, the device stay awake 2h now after flashing the kernel.

Seeing that myself as well. Guessing something related to the Moto Voice glitch (mine Force Closes from time to time).

Nope, didn't work. I try it 3 times. TWRP says "successfully" after the zip flash but Android reboot with the original Kernel.
With your TWRP it is no problem.
The deep sleep issues: i have no, BUT i have disabled many Motorola apps with Titanium (Moto Voice too)
the kernel is going well
the system runs a little better and the CPU is clocked down faster which saves battery.
However, the read / write rates from the internal memory card have become worse. Have tested it with Androbench.
about 1000 iops fewer
I/O Scheduler: Fiops with 1024kb Read-Ahead
but that's not so bad
Thank you for your effort
if I may donate you a coffee / beer, tell me

Thank you, finally some led notifikation action

Thanks, also to note have flashed back a stock boot.img file via fastboot and can't get on WiFi? The WiFi toggle goes straight back to off? So can either go back to stock and have working Moto Voice but no WiFi, or use your Kernel and have no Moto Voice I used the boot.img here: http://forum.xda-developers.com/moto-x-play/general/recovery-boot-img-t3191436 My phone is the same version as listed, XT1562 EU any ideas please?

That's because the WiFi kernel module must match the kernel. Had you taken a system backup prior to flashing my kernel? If so, restore it. Otherwise, reflash system and boot, and then re-root your device if you want.

Did the two of you have Moto Voice set up before flashing the kernel? I'm not having any wakelock issues myself, but I had never set up Moto Voice. I'll try to reproduce the wakelock issue when I get time.

I did. Maybe I'll load wakelock detector to confirm if Moto Voice is the culprit.

Will wait until Moto Voice bug is eliminated to install it.

Moto Voice Status
After some testing, I can confirm that nothing I did broke Moto Voice. I took the osprey stock kernel and added in a minimal set of patches to get it working on lux. Unfortunately, the Moto Voice issue was still present there. It doesn't make much sense to waste many hours trying to figure out what change is needed to fix Moto Voice when Motorola has already fixed the issue and will be releasing kernel sources soon. Thus, you'll probably have to wait for Motorola to release kernel sources for me to fix Moto Voice.

How long can we expect Motorola to make us wait for it. How timely have they been in the past. This is my first Motorola since the Moto Defy!

Yes figured that and restored my boot and system from TWRP thanks, thought it best to mention in case anyone else wanted to revert back to stock Thanks for the quick feedback, will give your kernel a go again once it's all working.

Hey man, remember to not ask for ETA on XDA. As a Moto Play user, I know exactly your feelings about this first kernel [emoji106]
PS: Motorola hasn't take long about releasing it's sources.
Cheers
Moto X Play nice

This one's different lol. Not asking a dev, but rather how long the OEM takes to release on average.
I play nice!! Sometimes ... Lol
