Creator/Creator3D changes



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

Hello,

yesterday I committed a bunch of changes to the ffb driver to implement hardware acceleration for character drawing etc. so we don't have to access the framebuffer anymore. While there I noticed that the driver does an awful lot of syncing which on my ffb2+ is unnecessary. According to the documentation font drawing operations could interfere with blitter operations but I found no evidence of that. Also, the documentation says nothing about writes to the font data register being pipelined or not - so far my 450MHz US-IIs failed to make it overflow. That said, if you have an old pre-ffb2 Creator or Creator3D please check if there are any weird side effects. If you see any they should go away when you put
options FFB_SYNC
into your kernel config.

have fun
Michael
