I'm trying to do this way you suggested.
I encoutnered following issues:
1. I can't find mknod. Is there any other way to create a character
device on android?
I've tried to use mknod from libc but i get "illegal instruction"
message (the same program compiled on linux works and create character
device)
2. How can I check if kernel was compiled with adding module capability?
I need to create my own fb and so device driver that will push
data from frame buffer into surface flinger.
Thanks,
