Hi!
My name is James Simmons and I'm one of the new core designers for the
framebuffer devices for linux. Well I have redesigned the framebuffer
system and now it takes advantages of accels. Now the problem is that alot
of cards can't have simulanteous access to the framebuffer and the accel
engine. What I need to a way to put any process to sleep when they access
the framebuffer while the accel engine is active. This is for both read
and write access. Then once the accel engine is idle wake up the process.
MM is beyond me. Trust me I tried to find a solution. Anyone have a idea
what needs to be done? Thank you.
