From: Tim Rowley Date: Sun, 7 Aug 2016 02:10:14 +0000 (-0600) Subject: swr: [rasterizer core] split FE and BE stats X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4e8763cb0904c30d1962cf5ad52fe3a87be7b4bd;p=mesa.git swr: [rasterizer core] split FE and BE stats Separated FE stats out into its own structure. There are 17 FE vs 3 BE stat fields. Since there is only one FE thread per DC then we don't have to loop over all threads and sum up FE stats over all the worker threads. This also reduces size of DC since we only need to store one copy of the FE stats and not one per worker. Finally, we can use the new FE callback mechanism to update these.
