Solaris Dynamic Tracing Guide


The cpuinfo_t structure defines a CPU. As Table 26–2 indicates, arguments to both the enqueue and dequeue probes include a pointer to a cpuinfo_t. Additionally, the cpuinfo_t corresponding to the current CPU is pointed to by the curcpu variable. The definition of the cpuinfo_t structure is as follows:

typedef struct cpuinfo {
	processorid_t cpu_id;           /* CPU identifier */
	psetid_t cpu_pset;              /* processor set identifier */
	chipid_t cpu_chip;              /* chip identifier */
	lgrp_id_t cpu_lgrp;             /* locality group identifer */
	processor_info_t cpu_info;      /* CPU information */
} cpuinfo_t;

The cpu_id member is the processor identifier, as returned by psrinfo(1M) and p_online(2).

The cpu_pset member is the processor set that contains the CPU, if any. See psrset(1M) for more details on processor sets.

The cpu_chip member is the identifier of the physical chip. Physical chips may contain several CPUs. See psrinfo(1M) for more information.

The cpu_lgrp member is the identifier of the latency group associated with the CPU. See liblgrp(3LIB) for details on latency groups.

The cpu_info member is the processor_info_t structure associated with the CPU, as returned by processor_info(2).
