mmm, ...

I am thinking of a user-space library to do video acceleration on the
framebuffer, for initial use with vlc, as it already has an fbdev output
option.

If i want to do dma with this library, should i need to use the drm, or is
some other possibilities available ?

How will a user-space library using the accel engine (it would clearly need a
little 'driver' for each chip) cohabit with the acceleration used with fbcon ?

Also i suppose by "graphic" mode you are speaking about X, and by "text" mode,
you are speaking about fbcon ?

Who will be responsible for setting the accel engine in a different state ? as
XFree clearly thinks it is his responsability to do such. Or are you thinking
only about the new X server ?
