bummer, that bandwidth thing again

I did some profiling by clearing the framebuffer directly from the epiphany.

Short summary:

My screen is 1280x1024, 24-bit - don't know if that can be configured to fewer bits as i have no serial console and that's just how it starts up (at least it's not widescreen).

I know it's not the case but it appears as if the memory transfers are somehow synchronised with the framebuffer DMA. It's only getting about 60 fps. At any rate, they're running at the same speed.

Tagged hacking, parallella.
On my god, it's full of local binary patterns! | that sucked a bit
