##### Input Variables:
|
# LOCAL_MODULE: required. Module name for the build system.
|
# LOCAL_MODULE_CLASS: optional. Default is ETC.
|
# LOCAL_MODULE_PATH / LOCAL_MODULE_RELATIVE_PATH: required. (Relative) path of output file.
|
# If not defined, LOCAL_MODULE_RELATIVE_PATH will be "vintf".
|
# LOCAL_MODULE_STEM: optional. Name of output file. Default is $(LOCAL_MODULE).
|
# LOCAL_SRC_FILES: required. Local source files provided to assemble_vintf
|
# (command line argument -i).
|
# LOCAL_GENERATED_SOURCES: optional. Global source files provided to assemble_vintf
|
# (command line argument -i).
|
#
|
# LOCAL_ADD_VBMETA_VERSION: Use AVBTOOL to add avb version to the output matrix
|
# (corresponds to <avb><vbmeta-version> tag)
|
# LOCAL_ASSEMBLE_VINTF_ENV_VARS: Add a list of environment variable names from global variables in
|
# the build system that is lazily evaluated (e.g. PRODUCT_ENFORCE_VINTF_MANIFEST).
|
# LOCAL_ASSEMBLE_VINTF_ENV_VARS_OVERRIDE: Add a list of environment variables that is local to
|
# assemble_vintf invocation. Format is "VINTF_ENFORCE_NO_UNUSED_HALS=true".
|
# LOCAL_ASSEMBLE_VINTF_FLAGS: Add additional command line arguments to assemble_vintf invocation.
|
# LOCAL_KERNEL_CONFIG_DATA_PATHS: Paths to search for kernel config requirements. Format for each is
|
# <kernel version x.y.z>:<path that contains android-base*.config>.
|
# LOCAL_GEN_FILE_DEPENDENCIES: A list of additional dependencies for the generated file.
