From 5da246944a787b933a509f0b65bab466574c3339 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Mon, 15 Nov 2010 14:53:21 -0500 Subject: gallium/noop: no operation gallium driver This driver is a fake swdri driver that perform no operations beside allocation gallium structure and buffer for upper layer usage. It's purpose is to help profiling core mesa/gallium without having pipe driver overhead hidding hot spot of core code. scons file are likely inadequate i am unfamiliar with this build system. To use it simply rename is to swrast_dri.so and properly set LIBGL_DRIVERS_PATH env variable.
