Probes

The SDT probes defined by the Solaris kernel are listed in Table 22-1. The name stability and data stability of these probes are both Private because their description here thus reflects the kernel's implementation and should not be inferred to be an interface commitment. For more information about the DTrace stability mechanism, see Stability.

Table 22-1 SDT Probes

Probe name

Description

arg0

callout-start

Probe that fires immediately before executing a callout (see <sys/callo.h>). Callouts are executed by periodic system clock, and represent the implementation for timeout(9F).

Pointer to the callout_t (see <sys/callo.h>) corresponding to the callout to be executed.

callout-end

Probe that fires immediately after executing a callout (see <sys/callo.h>).

Pointer to the callout_t (see <sys/callo.h>) corresponding to the callout just executed.

interrupt-start

Probe that fires immediately before calling into a device's interrupt handler.

Pointer to the dev_info structure (see <sys/ddi_impldefs.h>) corresponding to the interrupting device.

interrupt-complete

Probe that fires immediately after returning from a device's interrupt handler.

Pointer to dev_info structure (see <sys/ddi_impldefs.h>) corresponding to the interrupting device.
