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. Signed-off-by: Jerome Glisse <jglisse@redhat.com>
