| 31 | * Definitions of terms (these definitions are for IA64 ONLY. Other architectures | ||
| 32 | * use cpuid/cpunum quite defferently): | ||
| 33 | * | ||
| 34 | * CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies | ||
| 35 | * the cpu. The value cpuid has no significance on IA64 other than | ||
| 36 | * the boot cpu is 0. | ||
| 37 | * smp_processor_id() returns the cpuid of the current cpu. | ||
| 38 | * | ||
| 39 | * CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID) | ||
| 40 | * This is the same as 31:24 of the processor LID register | ||
| 41 | * hard_smp_processor_id()- cpu_physical_id of current processor | ||
| 42 | * cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid> | ||
| 43 | * cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid> | ||
| 44 | * * not real efficient - don't use in perf critical code | ||
| 45 | * | ||
| 46 | * SLICE - a number in the range of 0 - 3 (typically) that represents the | ||
| 47 | * cpu number on a brick. | ||
| 48 | * | ||
| 49 | * SUBNODE - (almost obsolete) the number of the FSB that a cpu is | ||
| 50 | * connected to. This is also the same as the PI number. Usually 0 or 1. | ||
| 51 | * | ||
| 52 | * NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no | ||
| 53 | * significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM. | ||
| 54 | * | ||
| 55 | * | ||
| 56 | * The macros convert between cpu physical ids & slice/nasid/cnodeid. | ||
| 57 | * These terms are described below: | ||
