From c944b91190048e370d2adc362f0860d9f58e58f2 Mon Sep 17 00:00:00 2001 From: Jose Fonseca Date: Fri, 13 Feb 2015 13:51:28 +0000 Subject: [PATCH] os,llvmpipe: Set rasterizer thread names on Linux. To help identify llvmpipe rasterizer threads -- especially when there can be so many. We can eventually generalize this to other OSes, but for that we must restrict the function to be called from the current thread.
