[EVO 4G Android Development] atyoung:
Introducing the Mason kernel.

​

This started as a project to bring sbc to the supersonic ICS aokp rom. However I decided to go ahead and move forward with moving over some of the fine work that is going on for the Nexus line and bring it over to our beloved evo4g. I want to stress that to my knowledge the things that will be included beyond what is in tiamat/CM9 proper are not very well tested on our platform.

The overwhelming goal is to bring performance and stability improvements to the supersonic platform. The original idea, had a little less scope. I have now broadened its scope to include ICS, GB, and even Sense soon. The project will actually breed a whole line of kernels built for the supersonic with the needs of it's community in mind. Let's breathe some new life into our platform.

Thanks to the evervolv team without which we wouldn't have ICS on the supersonic at the moment.

Kernel Features:

CPU Frequency governors: conservative, ondemand, ondemandX, interactive, interactiveX, smartass, smartassV2, intellidemand, SavagedZen, minmax, lulzactive, lazy, lagfree, userspace, powersave, Lionheart, brazillianwax

I/O Schedulers: deadline (flash optimized), vr, noop, cfq, bfq, sio

HAVS, KSM (I series), Ext2/3/4, NTFS

Variants:

nosbc - Standard kernel without sbc

sbc - Smart Battery Control

hwa - Hardware Acceleration

fso - File synchronization off

Note on FSO:

I provide this without any warranty at all (not that I do with anything else). Yes, fso makes things faster, it's for the speed hungry among you, however there is the potential, however slight that you can get corrupted data on a crash. Do not run this without a proper nand, it's just a bad idea. I haven't personally had any issues, but that doesn't mean that in theory it can't happen. It's a very strong possibility however slight it might be. The price you pay for speed I suppose.

Note on SBC:

There are some out there who find sbc and unholy abomination. Though again I have not experienced issues personally, there are some out there that claim that it can damage your battery, particularly the lifetime of the battery. There is data to support both sides of this argument, and I'm not here to go over all that. But be warned that it may cause some battery issues, and take care that you are both advised of the risks and willing to take them for some extra juice.

TODO:

* Slated for v0.15/6 sense variant. Yeah you heard me, all your kernels r belong to us.

* Slated for v0.15 Various performance optimizations relating to RCU and power consumption.

* Slated for v0.15 2 more governors.

* Slated for v0.15 Backport of cpufreq from linux 3.0.y.

* Slated for v0.2 Merging of the lines to give us one base kernel instead of 2.

* Slated for v0.3 Linux v3.x.x Lot of work to be done here. Lots of 3.x.x code already being back ported.

Instructions:

Apply with your custom recovery. Amen Ra Style Recovery 3.11 recommended (But not required).

Side note:

I will try my hardest to maintain both this and the rootzwiki thread as time allows. That said let's keep the discussion pleasant and on the topic of bugs and features supersonic users would like to see either quashed or provided respectively. I feel bad for slightly hijacking the aokp and other ICS threads so lets move the kernel relevant conversation here.
