Re: Kernel Display and Video API Consolidation mini-summit at ELC 2012 - Notes

Ensuring that nothing prevents the switch to fbcon and displaying the
panic message is the reason why we haven't felt inclined to accelerate
fbcon - it just gets messy for no real gain.

and when doing 2d accel on a 3d core..  it basically amounts to
putting a shader compiler in the kernel.   Wheeee!

Yikes. I'm not suggesting that. In fact I doubt accelerating the imageblit
would be worthy it due to the small size of the images being pushed. The 
real cost is the copyarea which is used for scrolling when no panning is 
available.

For example: https://bugs.freedesktop.org/attachment.cgi?idH933
which doesn't handle flushing of pending updates via the GPU when
writing with the CPU during interrupts (i.e. a panic).
