From f5da73b6881991a28844ed59e8dcc1d154ddae7e Mon Sep 17 00:00:00 2001 From: Steve Reinhardt Date: Thu, 23 Oct 2003 19:07:52 -0700 Subject: Initial support for CPU switching. New SamplingCPU object encompasses a set of CPUs that get switched round-robin (though currently we're only shooting for two CPUs and one switch event, and even that doesn't quite work yet). Registration of ExecContexts with System/Process object factored out so we can create two CPUs but only register one of them at a time. Also worked at making behavior and naming in System and Process objects more consistent. arch/alpha/ev5.cc: Rename ipr_init to initIPRs and get rid of unused mem arg. arch/alpha/fake_syscall.cc: Process:numCpus is now a function (not a data member). base/remote_gdb.hh: Support for ExecContext switching. cpu/base_cpu.cc: cpu/base_cpu.hh: cpu/exec_context.cc: cpu/exec_context.hh: cpu/simple_cpu/simple_cpu.hh: Support for ExecContext switching. Renamed contexts array to execContexts to be consistent with Process. CPU ID now auto-assigned by system object. cpu/simple_cpu/simple_cpu.cc: Support for ExecContext switching. Renamed contexts array to execContexts to be consistent with Process. CPU ID now auto-assigned by system object. Cleaned up MP full-system initialization a bit. dev/alpha_console.cc: Renamed xcvec array to execContexts to be consistent with Process. kern/tru64/tru64_system.cc: kern/tru64/tru64_system.hh: Support for ExecContext switching. CPU ID now auto-assigned by system object. sim/prog.cc: sim/prog.hh: Support for ExecContext switching. Process:numCpus is now a function (not a data member). sim/system.cc: sim/system.hh: Support for ExecContext switching. Renamed xcvec array to execContexts to be consistent with Process. --HG-- extra : convert_revision : 79649cffad5bf3e83de8df44236941907926d791 --- dev/alpha_console.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'dev') diff --git a/dev/alpha_console.cc b/dev/alpha_console.cc index b917d7a96..cd03b3656 100644 --- a/dev/alpha_console.cc +++ b/dev/alpha_console.cc @@ -153,7 +153,7 @@ AlphaConsole::write(MemReqPtr req, const uint8_t *data) int cpu = val; assert(cpu > 0 && "Must not access primary cpu"); - ExecContext *other_xc = req->xc->system->xcvec[cpu]; + ExecContext *other_xc = req->xc->system->execContexts[cpu]; other_xc->regs.intRegFile[16] = cpu; other_xc->regs.ipr[TheISA::IPR_PALtemp16] = cpu; other_xc->regs.intRegFile[0] = cpu; -- cgit v1.2.3
