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/cpu/ozone/lw_lsq.hh | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) (limited to 'src/cpu/ozone/lw_lsq.hh') diff --git a/src/cpu/ozone/lw_lsq.hh b/src/cpu/ozone/lw_lsq.hh index 4817622f5..1add13894 100644 --- a/src/cpu/ozone/lw_lsq.hh +++ b/src/cpu/ozone/lw_lsq.hh @@ -256,11 +256,13 @@ class OzoneLWLSQ { virtual void recvFunctional(PacketPtr pkt); - virtual void recvStatusChange(Status status); + virtual void recvRangeChange(); - virtual void getDeviceAddressRanges(AddrRangeList &resp, - bool &snoop) - { resp.clear(); snoop = true; } + /** + * Is a snooper due to LSQ maintenance + */ + virtual bool isSnooping() + { return true; } virtual bool recvTiming(PacketPtr pkt); -- cgit v1.2.3
