From 07cf9d914b292008ead7021182ec2ef8fc4671f1 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Tue, 17 Jan 2012 12:55:09 -0600 Subject: MEM: Separate queries for snooping and address ranges This patch simplifies the address-range determination mechanism and also unifies the naming across ports and devices. It further splits the queries for determining if a port is snooping and what address ranges it responds to (aiming towards a separation of cache-maintenance ports and pure memory-mapped ports). Default behaviours are such that most ports do not have to define isSnooping, and master ports need not implement getAddrRanges. --- src/sim/system.hh | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/sim') diff --git a/src/sim/system.hh b/src/sim/system.hh index eedd11e85..53f1762c7 100644 --- a/src/sim/system.hh +++ b/src/sim/system.hh @@ -102,7 +102,13 @@ class System : public MemObject { panic("SystemPort does not receive atomic!\n"); return 0; } void recvFunctional(PacketPtr pkt) { panic("SystemPort does not receive functional!\n"); } - void recvStatusChange(Status status) { } + + /** + * The system port is a master port connected to a single + * slave and thus do not care about what ranges the slave + * covers (as there is nothing to choose from). + */ + void recvRangeChange() { } }; -- cgit v1.2.3
