From: Rob Clark Date: Sat, 21 Dec 2013 01:48:18 +0000 (-0500) Subject: freedreno: prepare for hw binning X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=be01d7a905d827c3c0c222cab2430c6d4575429a;p=mesa.git freedreno: prepare for hw binning Actually assign VSC_PIPE's properly, which will be needed for tiling. And introduce fd_tile for per-tile state (including the assignment of tile to VSC_PIPE). This gives us the proper pipe setup that we'll need for hw binning pass, and also cleans things up a bit by not having to pass so many parameters around. And will also make it easier to introduce different tiling patterns (since we may no longer render tiles in a simple left-to-right top-to-bottom pattern).
