Cyclics

The cyclic subsystem is a low-level kernel subsystem that provides high resolution, per-CPU interval timer facilities to other kernel services and programming interfaces.

Cyclics Dcmds

::cycinfo [-vV]

Display the cyclic subsystem per-CPU state for each CPU. If the -v option is present, a more verbose display is shown. If the -V option is present, an even more verbose display than -v is shown.

address ::cyclic

Format and display the cyclic_t at the specified address.

::cyccover

Display cyclic subsystem code coverage information. This information is available only in a DEBUG kernel.

::cyctrace

Display cyclic subsystem trace information. This information is available only in a DEBUG kernel.

Cyclics Walkers

cyccpu

Iterate over the per-CPU cyc_cpu_t structures. This structure is defined in <sys/cyclic_impl.h>.

cyctrace

Iterate over the cyclic trace buffer structures. This information is only available in a DEBUG kernel.
