+
+End users writing applications that use the HPI interface do not have to

+
+HPI_DSPCODE_FILE:
+DSP code is supplied as a file that is opened and read from by the driver.
+
+HPI_DSPCODE_FIRMWARE:
+DSP code is read using the hotplug firmware loader module.
+ Only valid when compiling the HPI kernel driver under Linux.
