[Kernel][Linaro] Stock KK kernel for Falcon

knizmi · Jan 3, 2015

This is a near stock falcon 4.4.4 kernel built with the latest Linaro toolchain (Linaro GCC 4.9-2014.12) for all of those who prefer stock kernels and absolutely need those 10 extra points in Antutu

Differences from stock are just a few Cortex-A7 optimizations, F2FS patches from mainline 3.18 and linaro toolchain.

All credit goes to @bedalus, who started his kernel thread for Peregrine, fixed all the small bugs that made compiling with newer Linaro toolchains impossible and cherry picked all those F2FS patches.

Sources and tools used:
MotorolaMobilityLLC/kernel-msm
MotorolaMobilityLLC/vendor-qcom-opensource-wlan-prima
bedalus' patches
Christopher83's Linaro Toolchain

My repo, where all sources are merged

Changelog:
falcon_stock_4.4.4_linaro_4.9.3.zip
- stock kernel
- added necessary patches to make it compile with linaro
- some Cortex-A7 optimizations

falcon_kernel_4.4.4_v2.zip
- same as falcon_stock_4.4.4_linaro_4.9.3.zip
- filesystem patches in line with mainline linux 3.18
- removed some debug info

The zip can be flashed with TWRP or CWM. Not flashable through fastboot.

Thanks @knizmi. I think stock users will appreciate this

Anyone tested? How the battery?

This is the stock kernel, so the batttery is as good as with stock kernel (you really can´t make it much better in any way). These screenshots are taken after some 7 hours of sleep.

Works pretty good on XT1031. Nice work! Any chance you could make a build with the kexec hardboot patch to use it with multirom?

I immediately noticed a performance improvement after flashing this kernel. Thanks!

Hi @knizmi

I said wait til I push a new branch, but I figure it's easier if you pull just a patch with

Code:

wget https://github.com/bedalus/moggy/commit/ead900a02071506c267fdebd292cbb2cdb31f4bd.patch

then you can apply it with

Code:

git am ead900a02071506c267fdebd292cbb2cdb31f4bd.patch

This is my preferred way to grab commits. Did you add my repo as a remote?

Battery life is really good on this kernel thank u dev

Thanks a bunch, this should really make merging those patches easy!

I have added your repo as a remote now. I was fighting with git last week quite a bit (never used that devil's tool before), but now I think I am getting used to it. For my first build I've just "patched" those files with gedit...

Thanks for the heads up, but compiling someone else's sources doesn't make me a dev

New version uploaded.

falcon_kernel_4.4.4_v2.zip
- same as falcon_stock_4.4.4_linaro_4.9.3.zip
- filesystem patches in line with mainline linux 3.18
- removed some debug info

Thanks @bedalus.

Sorry, the aim of this is to stay as close to stock as possible and only add optimizations/update drivers.

If you've got my repo as a remote you should be able to see my commits with

Code:

git log -- bedalus/moggy

depending on what you named your remote.

Once you see what commits you want, copy their hashes (the long string of letters/numbers) then

Code:

git cherry-pick *hash*

If there's a problem with the cherry-pick you can fix it manually with

Code:

git mergetool

or abort with [git cherry-pick --abort[/code]

I've installed meld as my mergetool. I'm using a debian derivative so I did

Code:

sudo apt-get install meld

That's a pretty comprehensive quick-start guide to cherry-picking from any remotes you've fetched.

Cannot downgrade to default stock.
can you make a zip with libs to go back.

That zip doesn't have libs. I made a zip for this a while ago, but it doesn't completely put everything back to stock. The best way seems to be to reflash stock ROM zip.

You mean in the thread I've posted. I've thought that too at the beginning, but they are there separately, look for Stock Kernel Modules: [XT1032] - 4.4.2 | 4.4.3 | 4.4.4 | 4.4.4 (GPE) | 5.0.1 (GPE) | [XT1033] (Dual-SIM) - 4.4.4. You just have to flash two zips instead of one.

amarc78 · Jan 10, 2015

Ahh, I forgot that was there. I have XT1031. Are the 1032 libs the same?
Edit: never mind. They look the same.

Not sure, you can try. If there is a problem you can always reflash stock /system, backup those modules and perhaps send them to @lost101

Thank you for the info again. You are very helpful.
Do I understand it correctly that I need to fetch your repo before I can start cherry-picking? Searching around the internet , it looks like it. I may give it a try one day, but for now I will stick with git am, which seems like the perfect tool to pick single commits from many repos.
