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.
