# Software behaviour defines
#

# The following defines are used to override default behaviour of which heap is selected for allocations.
# The default is to pick system heap.
# The following two defines enable either DMA heap or compound page heap for when the usage has
# GRALLOC_USAGE_HW_FB or GRALLOC_USAGE_HW_COMPOSER set and GRALLOC_USAGE_HW_VIDEO_ENCODER is not set.
# These defines should not be enabled at the same time.

# When enabled, forces format to BGRA_8888 for FB usage when HWC is in use

# When enabled, disables AFBC for FB usage when HWC is in use
