Subject: r300g: Clear up a bit of the buffer reference stuff.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6007e2e0085d9131b22dc8a98d7500a66a0e4c97;p=mesa.git

r300g: Clear up a bit of the buffer reference stuff.

Still need to actually get reference info from winsys somehow. Doing added
buffers is easy, but knowing whether a flush has happened is a bit tricky.
