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.

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. |
