From df973abef3a70074971375cfe52c46f53528c00e Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Thu, 16 Oct 2014 05:49:43 -0400 Subject: mem: Dynamically determine page bytes in memory components This patch takes a step towards an ISA-agnostic memory system by enabling the components to establish the page size after instantiation. The swap operation in the memory is now also allowing any granularity to avoid depending on the IntReg of the ISA. --- src/mem/ruby/structures/Prefetcher.hh | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/mem/ruby/structures/Prefetcher.hh') diff --git a/src/mem/ruby/structures/Prefetcher.hh b/src/mem/ruby/structures/Prefetcher.hh index 2bc7d812e..6ed945b9e 100644 --- a/src/mem/ruby/structures/Prefetcher.hh +++ b/src/mem/ruby/structures/Prefetcher.hh @@ -41,6 +41,7 @@ #include "mem/ruby/system/System.hh" #include "params/Prefetcher.hh" #include "sim/sim_object.hh" +#include "sim/system.hh" #define MAX_PF_INFLIGHT 8 @@ -139,6 +140,9 @@ class Prefetcher : public SimObject bool accessNonunitFilter(const Address& address, int *stride, bool &alloc); + /// determine the page aligned address + Address pageAddress(const Address& addr) const; + //! number of prefetch streams available uint32_t m_num_streams; //! an array of the active prefetch streams @@ -187,6 +191,8 @@ class Prefetcher : public SimObject AbstractController *m_controller; + const Addr m_page_shift; + //!
