From 8aaa39e93dfe000ad423b585e78a4c2ee7418363 Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Sun, 12 Feb 2012 16:07:38 -0600 Subject: mem: Add a master ID to each request object. This change adds a master id to each request object which can be used identify every device in the system that is capable of issuing a request. This is part of the way to removing the numCpus+1 stats in the cache and replacing them with the master ids. This is one of a series of changes that make way for the stats output to be changed to python. --- src/mem/cache/prefetch/base.hh | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/mem/cache/prefetch/base.hh') diff --git a/src/mem/cache/prefetch/base.hh b/src/mem/cache/prefetch/base.hh index ead163215..1517be50c 100644 --- a/src/mem/cache/prefetch/base.hh +++ b/src/mem/cache/prefetch/base.hh @@ -70,7 +70,7 @@ class BasePrefetcher : public SimObject unsigned degree; /** If patterns should be found per context id */ - bool useContextId; + bool useMasterId; /** Do we prefetch across page boundaries. */ bool pageStop; @@ -80,6 +80,12 @@ class BasePrefetcher : public SimObject /** Do we prefetch on only data reads, or on inst reads as well. */ bool onlyData; + /** System we belong to */ + System* system; + + /** Request id for prefetches */ + MasterID masterId; + public: Stats::Scalar pfIdentified; -- cgit v1.2.3
