[RFC PATCH 0/2] drm/mgag200: Use 24bit format in VRAM

[Jocelyn Falempe]

The bandwidth between system memory and VRAM is very limited
on G200.
So when using a 32bit framebuffer on system memory, convert it to 24bit
when copying the frame to the VRAM, this allows to go 33% faster.
Converting the format on the fly is negligible, even on low end CPU.

[PATCH 1/2] drm/mgag200: simplify offset and scale computation.
