| 35 * 36 * Each architecture determines the mapping of logical CPU IDs to physical 37 * CPUs. The requirements of this mapping are as follows: 38 * - Logical CPU IDs must reside in the range 0 ... MAXCPU - 1. 39 * - The mapping is not required to be dense. That is, there may be 40 * gaps in the mappings. 41 * - The platform sets the value of MAXCPU in <machine/param.h>. 42 * - It is suggested, but not required, that in the non-SMP case, the 43 * platform define MAXCPU to be 1 and define the logical ID of the 44 * sole CPU as 0. |
