- Add the --prm flag to the GENFW_FLAGS - Add the --no-gc-section to the linker flags so that apparently unreferenced symbols are not prematurely removed from the .dll which is used to generate the Prm module .efi. - Force the linker to maintain the PrmModuleExportDescriptor symbol. - Force the linker to maintain the PRM handler funtion's symbol.

# Sample PRM Driver
|
|
#
|
|
# A sample PRM Module implementation. This PRM Module includes a PRM Module configuration library instance
|
|
# that applies the configuration for the PRM context data in the boot environment. A PRM handler
|
|
# is provided that accesses the context buffer resources and prints their value at OS runtime.
