heads up: hw acceleration for crmfb



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I just committed code to support hardware acceleration in crmfb. To use the drawing engine we have to run the framebuffer in native, tiled mode which currently breaks X but now that I know more or less how the thing works I think I'll come up with a driver for X pretty soon. There are a few more things I could do to speed things up. Right now we always wait for the engine to become completely idle before issuing another command, mainly because I haven't
found the register holding the pipeline level yet.
We use the rendering engine for everything except character drawing - crime doesn't support colour expansion so we draw them into an off- screen buffer and blit them into place, that way
we don't have to teach rasops about tiled framebuffers.

have fun
Michael
