From: Kevin Lim Date: Sun, 19 Nov 2006 22:43:03 +0000 (-0500) Subject: Update Virtual and Physical ports. X-Git-Tag: m5_2.0_beta2~21 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a2113fd3dc85798c7dcc1d67691ffd29a86ef5a0;p=gem5.git Update Virtual and Physical ports. src/cpu/o3/alpha/cpu_impl.hh: Handle the PhysicalPort and VirtualPort in the ThreadState. src/cpu/o3/cpu.cc: Initialize the thread context. src/cpu/o3/thread_context.hh: Add new function to initialize thread context. src/cpu/o3/thread_context_impl.hh: Use code now put into function. src/cpu/simple_thread.cc: Move code to ThreadState and use the new helper function. src/cpu/simple_thread.hh: Remove init() in this derived class; use init() from ThreadState base class. src/cpu/thread_state.cc: Move setting up of Physical and Virtual ports here. Change getMemFuncPort() to connectToMemFunc(), which connects a port to a functional port of the memory object below the CPU. src/cpu/thread_state.hh: Update functions. --HG-- extra : convert_revision : ff254715ef0b259dc80d08f13543b63e4024ca8d --- diff --git a/src/cpu/o3/alpha/cpu_impl.hh b/src/cpu/o3/alpha/cpu_impl.hh index b2ef78360..98fd0699a 100644 --- a/src/cpu/o3/alpha/cpu_impl.hh +++ b/src/cpu/o3/alpha/cpu_impl.hh @@ -116,24 +116,6 @@ AlphaO3CPU::AlphaO3CPU(Params *params) #if FULL_SYSTEM // Setup quiesce event. this->thread[i]->quiesceEvent = new EndQuiesceEvent(tc);
