what the acronyms sa and bo stand for?

thanks

sa = sub-allocator
bo = buffer object

thanks a lot, everything is a bit clearer now.
It will be great if somebody adds this explanation as a comment to the appropriate places in source code.

In the drm source code for radeon, the acronyms sa and bo are very frequently used (for example, in radeon_sa.c) , but nowhere explained. my guesses are

sa = standalone allocator???
bo = buffer object????

does anybody know what these acronyms represent??

from my reading of the source code, I deduce that they relate to memory allocation for ring buffer, but I am not sure.

sa = sub-allocator
bo = buffer object
