added a hybrid-backing mode to membackend backing #2616

nab880 · 2025-12-18T01:34:45Z

This adds a hybrid backing the the MemHierarchy memory backing. The hybrid backing contains a malloc backing and a list of mmap backings. Upon receiving a request it first checks if the memory address is within address ranges of the mmap backings, otherwise it accesses using the malloc backing.
