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 asked if "wait for idle" was finished because i found this function on savage_bci.c "
int savage_do_bci_idle( drm_savage_private_t *dev_priv )" and i thought it was the wait for idle thing. Am I wrong?

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. (*) Tell me if you'r still not completely enlightened about them or what other terms are confusing.

I already read the glossary but what i wanted to know is how the interact with each other and what kind of information do they deal with. I don't really understand them and I may saying stupid things :).
Max.
(*) I'm flagging all my answers to you to add/update the FAQ aftewards.
