From 0c2c7171a83f772b297016aa7382157f070b3466 Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Thu, 2 Mar 2006 01:01:03 -0500 Subject: More progress... run a few instructions now, but die on the second memory access (I think because we're deallocating our one and only CpuRequest object). base/loader/aout_object.cc: base/loader/ecoff_object.cc: base/loader/elf_object.cc: Add flag to force allocation of new pages on data writes. cpu/simple/cpu.cc: Several minor fixes. Switch to atomic mode for now. mem/physical.hh: Don't copy the packet to the response event, just keep a reference to the original. mem/translating_port.cc: mem/translating_port.hh: Add parameter to writeBlobFunctional() to force allocation of unallocated pages on writes. --HG-- extra : convert_revision : 05cb31c7b0047b492dcfa0d12ddee690ef762b44 --- cpu/simple/cpu.cc | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'cpu') diff --git a/cpu/simple/cpu.cc b/cpu/simple/cpu.cc index 7da000a35..41acd2456 100644 --- a/cpu/simple/cpu.cc +++ b/cpu/simple/cpu.cc @@ -659,7 +659,7 @@ SimpleCPU::dbg_vtophys(Addr addr) void SimpleCPU::sendIcacheRequest() { -#if 1 +#if 0 bool success = icachePort.sendTiming(*pkt); unscheduleTickEvent(); @@ -674,7 +674,7 @@ SimpleCPU::sendIcacheRequest() _status = IcacheWaitResponse; } #else - Tick latency = icachePort.sendAtomic(pkt); + Tick latency = icachePort.sendAtomic(*pkt); unscheduleTickEvent(); scheduleTickEvent(latency); @@ -695,7 +695,7 @@ SimpleCPU::sendDcacheRequest() { unscheduleTickEvent(); -#if 1 +#if 0 bool success = dcachePort.sendTiming(*pkt); lastDcacheStall = curTick; @@ -706,7 +706,7 @@ SimpleCPU::sendDcacheRequest() _status = DcacheWaitResponse; } #else - Tick latency = dcachePort.sendAtomic(pkt); + Tick latency = dcachePort.sendAtomic(*pkt); scheduleTickEvent(latency); @@ -891,7 +891,7 @@ SimpleCPU::tick() /* memReq->reset(xc->regs.pc & ~3, sizeof(uint32_t), IFETCH_FLAGS(xc->regs.pc)); */ -//NEED NEW TRANSLATION HERE + fault = xc->translateInstReq(req); if (fault == No_Fault) { @@ -900,8 +900,10 @@ SimpleCPU::tick() pkt->addr = req->paddr; pkt->size = sizeof(MachInst); pkt->req = req; + pkt->data = (uint8_t *)&inst; sendIcacheRequest(); + return; /* fault = xc->mem->read(memReq, inst); if (icacheInterface && fault == No_Fault) { -- cgit v1.2.3
