TRACE_SOFTIRQ_RAISE(9) IRQ TRACE_SOFTIRQ_RAISE(9)
NAME
trace_softirq_raise - called immediately when a softirq is raised
SYNOPSIS
void trace_softirq_raise(struct softirq_action * h,
struct softirq_action * vec);
ARGUMENTS
h
pointer to struct softirq_action
vec
pointer to first struct softirq_action in softirq_vec array
DESCRIPTION
The h parameter contains a pointer to the softirq vector number which
is raised. vec is NULL and it means h includes vector number not
softirq_action. When used in combination with the softirq_entry
tracepoint we can determine the softirq raise latency.
