# Automatically converted from Mesa-17.2.4-intel-2017b.eb
# Original message:
# the purpose of the easyconfig is to build a Mesa for software rendering,
# not hardware rendering. This means you want at least SSE4.2. We build:
# - llvmpipe: the high-performance Gallium LLVM driver
# - swr: Intel's OpenSWR
# it will try to use the llvmpipe by default. It you want swr, do:
# GALLIUM_DRIVER=swr
