# This hardware composer implements version 2.0. It is to be used as a reference
# guide for writing HWC 2.0 implementations. To enable, add
# "TARGET_USES_HWC2 := true" to flounder's BoardConfig.mk.
# It is a 2D HAL (no GL acceleration). Enabling it will degrade performance.
# To disable, remove "TARGET_USES_HWC2 := true" and run "make installclean"
