CPU Structures and the Kernel Dispatcher

This section describes the facilities for examining the state of the CPU structures and the kernel dispatcher.

CPU and Dispatcher Dcmds

::callout

Display the callout table. The function, argument, and expiration time for each callout is displayed.

::class

Display the scheduling class table.

[ cpuid ] ::cpuinfo [-v]

Display a table of the threads currently executing on each CPU. If an optional CPU ID number or CPU structure address is specified prior to the dcmd name, only the information for the specified CPU is displayed. If the -v option is present, ::cpuinfo also displays the runnable threads waiting to execute on each CPU as well as the active interrupt threads.

CPU and Dispatcher Walkers

cpu

Iterate over the set of kernel CPU structures. The cpu_t structure is defined in <sys/cpuvar.h>.
