From 0b2deb2a8897fa857d2b3e1936401c6666fdc728 Mon Sep 17 00:00:00 2001 From: Kevin Lim Date: Thu, 30 Mar 2006 10:42:55 -0500 Subject: [PATCH] Fixes for full system compiling. arch/alpha/arguments.cc: There will not be a phys mem ptr in the XC in the newmem. This read will have to go through something else. arch/alpha/ev5.cc: Remove instantiations of these functions for the FastCPU, as the FastCPU is not really used. Also this messed up the ability to specify which CPU models are being built. cpu/exec_context.hh: Remove getPhysMemPtr() function. cpu/exetrace.cc: Include sim/system.hh, and sort the includes. cpu/simple/cpu.cc: Fixes for full system compilation. kern/system_events.cc: Remove include of encumbered FullCPU. The branch prediction will need to be fixed up in a more generic way in the future. --HG-- extra : convert_revision : a8bbf562a277aa80e8f40112570c0a825298a05c --- arch/alpha/arguments.cc | 4 +++- arch/alpha/ev5.cc | 9 --------- cpu/cpu_exec_context.cc | 9 ++++----- cpu/cpu_exec_context.hh | 17 ++++++++--------- cpu/exec_context.hh | 14 ++++---------- cpu/exetrace.cc | 5 +++-- cpu/simple/cpu.cc | 13 +++++++++---- kern/system_events.cc | 8 ++++++-- 8 files changed, 37 insertions(+), 42 deletions(-) diff --git a/arch/alpha/arguments.cc b/arch/alpha/arguments.cc index a782ea330..338581e32 100644 --- a/arch/alpha/arguments.cc +++ b/arch/alpha/arguments.cc @@ -60,7 +60,9 @@ AlphaArguments::getArg(bool fp) } else { Addr sp = xc->readIntReg(30); Addr paddr = vtophys(xc, sp + (number-6) * sizeof(uint64_t)); - return xc->getPhysMemPtr()->phys_read_qword(paddr); + // @todo: This read must go through the system or something else. +// return xc->getPhysMemPtr()->phys_read_qword(paddr); + return 0; } } diff --git a/arch/alpha/ev5.cc b/arch/alpha/ev5.cc index a5a8851c2..12f7659e6 100644 --- a/arch/alpha/ev5.cc +++ b/arch/alpha/ev5.cc @@ -36,7 +36,6 @@ #include "cpu/base.hh" #include "cpu/cpu_exec_context.hh" #include "cpu/exec_context.hh" -#include "cpu/fast/cpu.hh" #include "kern/kernel_stats.hh" #include "sim/debug.hh" #include "sim/sim_events.hh" @@ -575,12 +574,4 @@ CPUExecContext::simPalCheck(int palFunc) return true; } -//Forward instantiation for FastCPU object -template -void AlphaISA::processInterrupts(FastCPU *xc); - -//Forward instantiation for FastCPU object -template -void AlphaISA::zeroRegisters(FastCPU *xc); - #endif // FULL_SYSTEM diff --git a/cpu/cpu_exec_context.cc b/cpu/cpu_exec_context.cc index 0a3dc5675..4ada24068 100644 --- a/cpu/cpu_exec_context.cc +++ b/cpu/cpu_exec_context.cc @@ -54,12 +54,11 @@ using namespace std; // constructor #if FULL_SYSTEM CPUExecContext::CPUExecContext(BaseCPU *_cpu, int _thread_num, System *_sys, - AlphaITB *_itb, AlphaDTB *_dtb, - Memory *_mem) + AlphaITB *_itb, AlphaDTB *_dtb) : _status(ExecContext::Unallocated), cpu(_cpu), thread_num(_thread_num), - cpu_id(-1), lastActivate(0), lastSuspend(0), mem(_mem), itb(_itb), - dtb(_dtb), system(_sys), memctrl(_sys->memctrl), physmem(_sys->physmem), - profile(NULL), quiesceEvent(this), func_exe_inst(0), storeCondFailures(0) + cpu_id(-1), lastActivate(0), lastSuspend(0), system(_sys), itb(_itb), + dtb(_dtb), memctrl(_sys->memctrl), profile(NULL), + quiesceEvent(this), func_exe_inst(0), storeCondFailures(0) { proxy = new ProxyExecContext(this); diff --git a/cpu/cpu_exec_context.hh b/cpu/cpu_exec_context.hh index 236619752..83afb3b85 100644 --- a/cpu/cpu_exec_context.hh +++ b/cpu/cpu_exec_context.hh @@ -121,9 +121,6 @@ class CPUExecContext System *system; - /// Port that syscalls can use to access memory (provides translation step). - TranslatingPort *port; -// Memory *mem; #if FULL_SYSTEM AlphaITB *itb; @@ -167,6 +164,9 @@ class CPUExecContext void profileSample(); #else + /// Port that syscalls can use to access memory (provides translation step). + TranslatingPort *port; + Process *process; // Address space ID.
