Thanks for reply. I already ported ASHMEM to my kernel. But what about armv6 optimization in Android? Is there a patch available somewhere? Because by default cross compiler uses armv5te optimization, and this means android will work slow on my cpu,
Did you change bionic kernel headers for 31 kernel, or just compiled Android as is, i mean just downloaded from git and compile?
