From 5936c79ba0f3fd29ef2bbf41fcaddc78fcd9c75c Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Thu, 30 Mar 2006 18:06:00 -0500 Subject: Add a functional port that is used to load the original binaries in FS SE mode now has a port that goes to whatever toplevel mem object the CPU sees that does the appropriate translation for syscall emulation SConscript: translating port is a syscall emu only source arch/alpha/system.cc: base/loader/object_file.cc: base/loader/object_file.hh: Use the new functional port to write the binaries into memory cpu/cpu_exec_context.cc: cpu/cpu_exec_context.hh: cpu/simple/cpu.cc: We aren't always going to be writing straight to memory with syscalls support writing to a cache mem/port.hh: Add a simple unidirectional functional port that panics on any incoming requests mem/translating_port.hh: make translating port inherit from the simple port sim/system.cc: sim/system.hh: Add a functional port that is used to load the original binaries --HG-- extra : convert_revision : 9096866d0b23e3aceea68394abb76e63c0f8fd8d --- cpu/cpu_exec_context.cc | 4 ++-- cpu/cpu_exec_context.hh | 4 ++-- cpu/simple/cpu.cc | 2 +- 3 files changed, 5 insertions(+), 5 deletions(-) (limited to 'cpu') diff --git a/cpu/cpu_exec_context.cc b/cpu/cpu_exec_context.cc index f6edf4b13..a3e6cc432 100644 --- a/cpu/cpu_exec_context.cc +++ b/cpu/cpu_exec_context.cc @@ -80,7 +80,7 @@ CPUExecContext::CPUExecContext(BaseCPU *_cpu, int _thread_num, System *_sys, } #else CPUExecContext::CPUExecContext(BaseCPU *_cpu, int _thread_num, - Process *_process, int _asid) + Process *_process, int _asid, MemObject* memobj) : _status(ExecContext::Unallocated), cpu(_cpu), thread_num(_thread_num), cpu_id(-1), lastActivate(0), lastSuspend(0), process(_process), asid(_asid), @@ -89,7 +89,7 @@ CPUExecContext::CPUExecContext(BaseCPU *_cpu, int _thread_num, /* Use this port to for syscall emulation writes to memory. */ Port *mem_port; port = new TranslatingPort(process->pTable, false); - mem_port = process->system->physmem->getPort("functional"); + mem_port = memobj->getPort("functional"); mem_port->setPeer(port); port->setPeer(mem_port); diff --git a/cpu/cpu_exec_context.hh b/cpu/cpu_exec_context.hh index 9bf548a45..7ceb7f2d8 100644 --- a/cpu/cpu_exec_context.hh +++ b/cpu/cpu_exec_context.hh @@ -205,8 +205,8 @@ class CPUExecContext CPUExecContext(BaseCPU *_cpu, int _thread_num, System *_system, AlphaITB *_itb, AlphaDTB *_dtb); #else - CPUExecContext(BaseCPU *_cpu, int _thread_num, Process *_process, - int _asid); + CPUExecContext(BaseCPU *_cpu, int _thread_num, Process *_process, int _asid, + MemObject *memobj); // Constructor to use XC to pass reg file around.
