StockMOD is a custom kernel for Ice Cream Sandwich on the HTC EVO 4G LTE, based on the stock HTC 2.13.651.1 kernel with some memory management and performance tweaks.
Freeza last worked on development for it in July when it was updated to the 1.22.651.3 base, and since then a developer going by ca1ne has picked up the project with permission and is running with it.
StockMOD’s main performance boost comes from a tweak that forces both cores to work when the screen is on. While no significant slowdown in responsiveness is noticeable when the second core is off and has to be turned on, you can see some improvement in some games and benchmarks by forcing it to be active.
Battery life should be a little worse than the HTC kernel this is based off of due to additional core activity, but it shouldn’t be significant.
There are two flavors of this kernel you can use: a dual-core always that has dimmed capacitive buttons, and one that doesn’t.
If you’re experiencing issues with anything but stock kernels and want to try for stability with options, this would be a good kernel to try.
