It's high time we got rid of our 8 CPU limit. Unfortunately, BeOS has
left us with B_MAX_CPU_NUM as a part of the public interface, what
makes it not a trivial task.
First of all, I believe B_MAX_CPU_NUM, system_info, cpu_info and
get_system_info() should be remove from public API (obviously
application would still be able to link against get_system_info(), the
binary interface remains unchanged). get_system_info() would keep
reporting no more than 8 CPUs due to the limitations of the
system_info type.
To keep environment consistent for the legacy applications sysconf()
would report no more than 8 CPUs if __gABIVersion <
B_HAIKU_ABI_GCC_2_HAIKU.
The above, should deal with the legacy binaries. New API has to be
created to allow programs to get system information in a more future
proof way. Here is what I propose:
