Since savage_bci.c doesn't have it, I conclude he didn't. IIRC what Andreas said at the time, the problem is that this function depends on the actual version of the Savage chipset family, so it's not a simple cut'n'paste from the XFree86 2D driver. After that, the next step would be create a function to write a buffer to the BCI and the respective ioctl (to be called by the libGL driver or, first, a test program). > I think you already noticed but i'm not really familiar with all > these terms like: MMIO, PIO, SEARS etc. I already read the faq but i think > i didn't get the whole idea.

Have you noticed the explanations in the FAQ?: http://dri.sourceforge.net/doc/faq/glossary.html#MMIO-TERM http://dri.sourceforge.net/doc/faq/glossary.html#PIO-TERM http://dri.sourceforge.net/doc/faq/architecture.html#SAREA-DEFINITION They may not be totally clear.
