Hello guys!
Could you tell me please, what do you think about log meggases in my
previous letter?
In previous messages you told that framebuffer driver for android must
have double buffering.
I found in the internet some articles which describe android frame
buffer.
Here they are:
http://pdk.android.com/online-pdk/guide/display_drivers.html
http://wiki.kldp.org/wiki.php/AndroidPortingOnRealTarget
Coul you tell me, is it enough functionality, which describes in those
artickes, i should implement for my android framebuffer driver?
Thanks a lot!
