function to return the total number of CPUs and not the highest CPU id. o Define mp_maxid based on the minimum of the actual number of CPUs in the system and MAXCPU. o In cpu_mp_add, when the CPU id of the CPU we're trying to add is larger than mp_maxid, don't add the CPU. Formerly this was based on MAXCPU. Don't count CPUs when we add them. We already know how many CPUs exist. o Replace MAXCPU with mp_maxid when used in loops that iterate over the id space. This avoids a couple of useless iterations. o In cpu_mp_unleash, use the number of CPUs to determine if we need to launch the CPUs. o Remove mp_hardware as it's not used anymore. o Move the IPI vector array from mp_machdep.c to sal.c. We use the array as a centralized place to collect vector assignments. Note that we still assign vectors to SMP specific IPIs in non-SMP configurations. Rename the array from mp_ipi_vector to ipi_vector. o Add IPI_MCA_RENDEZ and IPI_MCA_CMCV. These are used by MCA. Note that IPI_MCA_CMCV is not SMP specific. o Initialize the ipi_vector array so that we place the IPIs in sensible priority classes. The classes are relative to where the AP wake-up vector is located to guarantee that it's the highest priority (external) interrupt. Class assignment is as follows: class IPI notes x AP wake-up (normally x=15) x-1 MCA rendezvous x-2 AST, Rendezvous, stop x-3 CMCV, test |
