2016-11-29dev: Fix buffer length when unserializing an eth pktMichael LeBeane
Changeset 11701 only serialized the useful portion of of an ethernet packets' payload. However, the device models expect each ethernet packet to contain a 16KB buffer, even if there is no data in it. This patch adds a 'bufLength' field to EthPacketData so the original size of the packet buffer can always be unserialized. Reported-by: Gabor Dozsa <Gabor.Dozsa@arm.com>
2016-10-26dev: Add 'simLength' parameter in EthPacketDatamlebeane
Currently, all the network devices create a 16K buffer for the 'data' field in EthPacketData, and use 'length' to keep track of the size of the packet in the buffer. This patch introduces the 'simLength' parameter to EthPacketData, which is used to hold the effective length of the packet used for all timing calulations in the simulator. Serialization is performed using only the useful data in the packet ('length') and not necessarily the entire original buffer.
2016-01-07dev: Distributed Ethernet link for distributed gem5 simulationsGabor Dozsa
Distributed gem5 (abbreviated dist-gem5) is the result of the convergence effort between multi-gem5 and pd-gem5 (from Univ. of Wisconsin). It relies on the base multi-gem5 infrastructure for packet forwarding, synchronisation and checkpointing but combines those with the elaborated network switch model from pd-gem5. --HG-- rename : src/dev/net/multi_etherlink.cc => src/dev/net/dist_etherlink.cc rename : src/dev/net/multi_etherlink.hh => src/dev/net/dist_etherlink.hh rename : src/dev/net/multi_iface.cc => src/dev/net/dist_iface.cc rename : src/dev/net/multi_iface.hh => src/dev/net/dist_iface.hh rename : src/dev/net/multi_packet.hh => src/dev/net/dist_packet.hh
