Hi,
This patch series adds more flexibility to u_upload_mgr. First, it adds the
ability to specify the alignment per suballocation. The idea is that several
users can use the same upload buffer, but each may need a different alignment.
Finally, it allows specifying PIPE_USAGE, which usually affects memory
placement.
Please review.
Marek

Hi Marek,
This patch series, or the commit
http://cgit.freedesktop.org/mesa/mesa/commit/?id=36c93a6fae275614b6004ec5ab085774d527e1bc
which was pushed around the same time, caused ipers framerate to drop on
llvmpipe from 12.8 to 6.8 FPS as seen in attached screenshot.
llvmpipe tends to be more more rasterization bound than most hw drivers,
which makes this even stranger.
I think there is a bug here somewhere -- maybe these changes are causing
more flushes than before.
Jose
