# Overview:
# Hexagon/QuRT apps are built in 2 parts, the part that runs on the
# application (apps) processor, and the library that is invoked on the DSP.
#
# PREREQUISITES:
#
# Environment variables:
# HEXAGON_TOOLS_ROOT
# HEXAGON_SDK_ROOT
#
# USAGE:
#
# For simple DSP apps that use a simple apps processor app to invoke the
# DSP lib, the QURT_BUNDLE function can be used.
#
# When the apps proc app requires its own cmake build, the RPC stub functions
# can be generated with FASTRPC_STUB_GEN. The DSP lib can be built with the
# QURT_LIB function and the apps proc app can be built with the help of the
# the FASTRPC_ARM_APP_DEPS_GEN function.
#
# Build targets to load the apps proc app and DSP libs are created from the
# rules below. Look for resulting make targets ending in -load.
include(fastrpc)
include(qurt_lib)
include(linux_app)
#
# Hexagon apps are started from an app running on the apps processor
# of the SoC. An RPC mechanism is used to load the app on the DSP and
# the RPC stubs are generated from a IDL complier (qaic). The RTOS on
# the DSP is QuRT but is often abstraced by the DSPAL APIs.
#
# The default idl file is <APP_NAME>.idl
#
# QURT_BUNDLE is used to specify the files and libraries to build
# in the DSP lib and in the apps application. The generated stubs are
# automatically build into the appropriate target.
#
# For an app named testapp, the result will be:
# testapp_app - Run on apps processor
# testapp.so - copy to target at /usr/share/date/adsp/
# testapp_skel.so - copy to target at /usr/share/date/adsp/
#
