[Kernel][osprey][merlin] Squid Kernel for Moto G 2015

[squid2]

This is my "Squid Kernel" for the 2015 Moto G, codenamed osprey. It shares a common codebase with my kernels for surnia and lux. It consists of the latest Motorola MSM8916 kernel, with all the latest changes from CodeAurora and Kernel.org merged in, along with select cherry-picks and additions of my own. Flash it using TWRP. Bug reports and contributions are welcome.

Version r22b and up require ROMs with an updated ACDB (audio calibration database) loader, such as LineageOS 14.1 builds from January 2018 and newer. If your ROM has an incompatible ACDB loader, you may experience low audio volume. Stick with version r22 for Marshmallow ROMs (including stock) and older Nougat ROMs without an updated ACDB loader.

Disclaimer:
This is for the 2015 Moto G (osprey and merlin) only! Don't flash it on a previous Moto G, or surnia, or lux. This kernel is provided AS-IS, with no warranties. I am not responsible for bricking your device. Flash at your own risk.

Installation Instructions

For the stock ROM and ROMs with WiFi drivers as a separate kernel module, use the "-osprey-stock" version of the kernel. For ROMs with WiFi drivers built into the kernel (such as CM12.1 nightlies), use the "-osprey" version.

Installation is easy as 123:

1. Boot into TWRP
2. Flash the kernel zip
3. Reboot back into your ROM

You can wipe cache and dalvik if you wish, but it's not required.

More Information

The surnia thread for this kernel is the original and may have useful historical information and more background. For information about my Lionfish governor, see this post in the surnia thread. For information about the memory usage benefits of this kernel, see this post on the surnia thread.

First flash kernel and than flash the Rom....Right?

No, the other way around. ROMs come with a default kernel that you need to replace, so flash the ROM first then flash the kernel.

 

[==vj==]

Thanks a lot for extending your support to Motorola's Stock ROM. This is going to be first kernel for stock.

Going to try osprey r9e first on my current PAC ROM.
Will get back on review after few hrs of analysis
Thank you..!

Im on official cm and im not joking when i say i was about to throw the fcking phone out of the window untill i flashed your kernel... Like day and night! Im coming from Oneplus 2 so you understand im used to speeeeeed

Can this be flashed on euphoria os ? If so which one I've to download ? Thanks in advance

 

[hp420]

OMG, my wifi and hotspot work again!!!! Thank you!!! I was about ready to flash a factory image because nothing was restoring functionality right!

I used the stock kernel on build .44 of the stock rom on xt1540 2gb...everything is running great!!

Thanks for all your hard work, @squid2 !!! You need a donation button so I can buy you a cup of coffee or a beer!!

 

[vandermark]

Great! Yesterday I updated last unofficial 22-9 build to 1-10 official build and flashed this kernel. Everything works supberb, great battery time & performance System uses 360-390 RAM. Great work!

How can I donate?

There should be a donate button under my avatar if you are view XDA on a wide screen, and a donate button will also be visible on the menu that appears when you click on my user name.

Squid Kernel r10

Today's release is a pretty nice one I think. As usual, I updated to the latest 3.10 series Linux from Kernel.org (3.10.90 in this case). On the new features front, I added the MDP5 KCAL colour control by @savoca and I incorporated optimized ARM crypto routines. On the optimization front, I cleaned up the defconfig to reduce size, and changed some configuration to significantly improve the performance of the virtual memory subsystem.

If you run a benchmarking tool like Antutu, you'll notice that the "RAM Speed" value will be higher on this build than on previous builds. If you're coming from r8, you may also notice that the "Storage IO" performance is higher than before, thanks to some optimizations (brought in from the lux kernel) that I added earlier in r9c.

Thanks for the stock ospery kernel
It's great and it doesn't break my wifi

Wiping cache and dalvik is must if flashed your last kernel?

Squid Kernel r10b

This new build should fix the r10 regression regarding moving apps to the SD card. If you encounter any other bugs please let me know and I'll fix them when I can.

You can wipe cache and dalvik if you want, but it isn't required.

Thank you for your work recently bought the Moto G 2015 and my battery lasted 5 hours not right in two hours of screen now ta lasting almost two days deep sleep ta not working well for me Your kernel .

Sorry my bad english.

 

[ryude]

Thank you so much squid2. This kernel really makes my phone feel alive and smooth!

 

[felipovicc]

Using it on stock rom, phone works much better, more free ram and also battery life is better!
Thanks for your development!
