[Xperia Z Android Development] Windows X:
Cheers to the first Linaro fully optimized KitKat 4.4.4 ROM I officially released. It took me a few months to fix my phone and get everything working below.

Features:

-jeroenqui’s Meow Kernel

-TWRP 2.7 Recovery

-Changed audio priority level to highest possible

-Compiled using latest Linaro toolchain version 4.7 and its own NDK

-Compiled with Linaro’s customized O3 optimizations with strict aliasing for both ROM and kernel

-Most strict-aliasing fixes are actual fixes from SlimSaber and my own

-High performance compiler flags optimizations

-Added bionic/framework optimizations from Linaro commits

-Fidelity Driver optimizations having

|-Added board audio optimizations for low latency/fluence/separated audio

|-Increased kernel’s audio clock synchronization frequency

|-Removed start threshold in HAL layer

|-Default sampling rate is set to 44100Hz

|-Reduce number of periods in kernel configuration

This ROM doesn’t come with Google apps so flash it after this ROM if you intend to use them. Using Fidelity Z 6.0 with this ROM is highly recommended.
