From 26d7b5a4d1ee06ce314093facdbef6389ee1ec55 Mon Sep 17 00:00:00 2001 From: Ali Saidi Date: Tue, 28 Feb 2006 18:41:04 -0500 Subject: [PATCH] Add quiesceNs, quiesceTime, quiesceCycles, and m5panic pseudo ops. This changeset removes a check that prevents quiescing when an interrupt is pending. *** You should only call quiesce if that isn't a problem. *** arch/alpha/isa/decoder.isa: sim/pseudo_inst.cc: sim/pseudo_inst.hh: Add quiesceNs, quiesceCycles, quisceTime and m5panic pseudo ops. These quiesce for a number of ns, cycles, report how long we were quiesced for, and panic the simulator respectively. The latter is added to the panic() function in the console and linux kernel instead of executing an infinite loop until someone notices. cpu/exec_context.cc: cpu/exec_context.hh: Add a quiesce end event to the execution contexted which upon executing wakes up a CPU for quiesceCycles/quiesceNs. util/m5/Makefile: Make the makefile more reasonable util/m5/m5.c: update the m5op executable to use the files from the linux tree util/m5/m5op.S: update m5op.S from linux tree util/m5/m5op.h: update m5op.h from linux tree --HG-- rename : util/m5/m5op.s => util/m5/m5op.S extra : convert_revision : 3be18525e811405b112e33f24a8c4e772d15462d --- arch/alpha/isa/decoder.isa | 14 ++- cpu/exec_context.cc | 47 +++++++-- cpu/exec_context.hh | 22 ++++- sim/pseudo_inst.cc | 38 ++++++- sim/pseudo_inst.hh | 5 +- util/m5/Makefile | 62 ++++++++---- util/m5/m5.c | 18 ++-- util/m5/m5op.S | 196 +++++++++++++++++++++++++++++++++++++ util/m5/m5op.h | 31 +++--- util/m5/m5op.s | 121 ----------------------- 10 files changed, 383 insertions(+), 171 deletions(-) create mode 100644 util/m5/m5op.S delete mode 100644 util/m5/m5op.s diff --git a/arch/alpha/isa/decoder.isa b/arch/alpha/isa/decoder.isa index 37b15416b..b93b6575c 100644 --- a/arch/alpha/isa/decoder.isa +++ b/arch/alpha/isa/decoder.isa @@ -1,6 +1,6 @@ // -*- mode:c++ -*- -// Copyright (c) 2003-2005 The Regents of The University of Michigan +// Copyright (c) 2003-2006 The Regents of The University of Michigan // All rights reserved. // // Redistribution and use in source and binary forms, with or without @@ -758,6 +758,15 @@ decode OPCODE default Unknown::unknown() { 0x01: quiesce({{ AlphaPseudo::quiesce(xc->xcBase());
