From 8a0bc840221cf7af4845f4ee44de11bc7271ff10 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Wed, 29 Jun 2005 01:20:41 -0400 Subject: Allow CPUs to specify their own CPU ids. Make the AlphaConsole calculate the number of CPUs instead of passing that in as a parameter. cpu/base.cc: pass the desired cpu_id into registerExecContext, offsetting it by the thread number. a cpu_id of -1 means that it should be generated for you. cpu/base.hh: Take the cpu_id as a parameter cpu/o3/alpha_cpu_builder.cc: cpu/simple/cpu.cc: Accept the cpu_id as a parameter while we're here, let's remove the multiplier since it is not used. dev/alpha_console.cc: don't take the number of CPUs as a parameter. Calculate it from the system based on the number of CPUs that have been registered. move init() code to startup() to ensure that all CPUs are registerd. dev/alpha_console.hh: python/m5/objects/AlphaConsole.py: don't take the number of CPUs as a parameter. move init() code to startup() to ensure that all CPUs are registerd. python/m5/objects/BaseCPU.py: take the cpu_id as a parameter. Default it to -1 which means that it will be generated. sim/system.cc: allow the registerExecContext functioin to take a desired cpu_id as a parameter. Check to ensure that the id isn't already used. Accept -1 as a request to have an id assigned. sim/system.hh: keep track of the number of registered exec contexts. provide a function for accessing the number of exec contexts that checks to ensure that they are all registered correctly. --HG-- extra : convert_revision : 8e12f96ff8a49fa16cdbbdb4c05c651376c35788 --- cpu/o3/alpha_cpu_builder.cc | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'cpu/o3/alpha_cpu_builder.cc') diff --git a/cpu/o3/alpha_cpu_builder.cc b/cpu/o3/alpha_cpu_builder.cc index 57061c052..57c567471 100644 --- a/cpu/o3/alpha_cpu_builder.cc +++ b/cpu/o3/alpha_cpu_builder.cc @@ -71,9 +71,9 @@ BEGIN_DECLARE_SIM_OBJECT_PARAMS(DerivAlphaFullCPU) #ifdef FULL_SYSTEM SimObjectParam system; +Param cpu_id; SimObjectParam itb; SimObjectParam dtb; -Param mult; #else SimObjectVectorParam workload; #endif // FULL_SYSTEM @@ -164,9 +164,9 @@ BEGIN_INIT_SIM_OBJECT_PARAMS(DerivAlphaFullCPU) #ifdef FULL_SYSTEM INIT_PARAM(system, "System object"), + INIT_PARAM(cpu_id, "processor ID"), INIT_PARAM(itb, "Instruction translation buffer"), INIT_PARAM(dtb, "Data translation buffer"), - INIT_PARAM(mult, "System clock multiplier"), #else INIT_PARAM(workload, "Processes to run"), #endif // FULL_SYSTEM @@ -274,9 +274,6 @@ CREATE_SIM_OBJECT(DerivAlphaFullCPU) DerivAlphaFullCPU *cpu; #ifdef FULL_SYSTEM - if (mult != 1) - panic("Processor clock multiplier must be 1?\n"); - // Full-system only supports a single thread for the moment. int actual_num_threads = 1; #else @@ -300,6 +297,7 @@ CREATE_SIM_OBJECT(DerivAlphaFullCPU) #ifdef FULL_SYSTEM params.system = system; + params.cpu_id = cpu_id; params.itb = itb; params.dtb = dtb; #else -- cgit v1.2.3
