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 |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.FreeBSD.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
