# 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.

# When enabled, allocations for display buffers will use physically contiguous memory.
GRALLOC_USE_CONTIGUOUS_DISPLAY_MEMORY?=0

# When enabled, forces format to BGRA_8888 for FB usage when HWC is in use
GRALLOC_HWC_FORCE_BGRA_8888?=0

# When enabled, disables AFBC for FB usage when HWC is in use
GRALLOC_HWC_FB_DISABLE_AFBC?=0

# When enabled, buffers will never be allocated with AFBC
GRALLOC_ARM_NO_EXTERNAL_AFBC?=0

# For hikey960 use contiguous memory for framebuffer allocations.
