| H A D | packet_access.hh | diff 11013:7e31bd5968c0 Fri Aug 07 04:59:00 EDT 2015 Andreas Sandberg <andreas.sandberg@arm.com> mem: Cleanup packet accessor methods The Packet::get() and Packet::set() methods both have very strange semantics. Currently, they automatically convert between the guest system's endianness and the host system's endianness. This behavior is usually undesired and unexpected. This patch introduces three new method pairs to access data: * getLE() / setLE() - Get data stored as little endian. * getBE() / setBE() - Get data stored as big endian. * get(ByteOrder) / set(v, ByteOrder) - Configurable endianness For example, a little endian device that is receiving a write request will use teh getLE() method to get the data from the packet. The old interface will be deprecated once all existing devices have been ported to the new interface. |
