android: Add scripts to build using meson
How to use:
- For GALLIUM drivers:
1. Add gallium drivers into your board.mk file:
board.mk:
BOARD_MESA3D_USES_MESON_BUILD := true
BOARD_MESA3D_GALLIUM_DRIVERS := lima panfrost v3d
2. Add the following packages into your device.mk file:
device.mk:
PRODUCT_PACKAGES += \
libEGL_mesa \
libGLESv1_CM_mesa \
libGLESv2_mesa \
libgallium_dri \
libglapi
- For VULKAN drivers:
1. Add single vulkan driver into your board.mk file:
board.mk:
BOARD_MESA3D_USES_MESON_BUILD := true
BOARD_MESA3D_VULKAN_DRIVERS := freedreno broadcom
2. Add the following package configuration into your device.mk file:
device.mk:
PRODUCT_PACKAGES += \
vulkan.freedreno
PRODUCT_PROPERTY_OVERRIDES += \
ro.hardware.vulkan=freedreno
- To build 'libgbm' set definition in the board.mk:
BOARD_MESA3D_BUILD_LIBGBM := true
And add a package to the device.mk:
PRODUCT_PACKAGES += libgbm
