Name:perf_event_create_kernel_counter*@attr: attributes of the counter to create*@cpu: cpu in which the counter is bound*@task: task to profile (NULL for percpu)
Proto:struct perf_event *perf_event_create_kernel_counter(struct perf_event_attr *attr, int cpu, struct task_struct *task, perf_overflow_handler_t overflow_handler, void *context)
Type:struct perf_event
Parameter:
Type | Parameter | Name |
---|---|---|
struct perf_event_attr * | attr | |
int | cpu | |
struct task_struct * | task | |
perf_overflow_handler_t | overflow_handler | |
void * | context |
11630 | If generate AUX records instead of events Then Return ERR_PTR( - EINVAL) |
11641 | owner = TASK_TOMBSTONE |
11652 | WARN_ON_ONCE(These fields let us detect when two contexts have both* been cloned (inherited) from a common ancestor.) |
11653 | mutex_lock( & Protect the list of events. Locking either mutex or lock* is sufficient to ensure the list doesn't change; to change* the list you need to lock both the mutex and the spinlock.) |
11654 | If task == TASK_TOMBSTONE Then |
11656 | Go to err_unlock |
11659 | If Not task Then |
11668 | If Not online Then |
11670 | Go to err_unlock |
11674 | If Not exclusive_event_installable(event, ctx) Then |
11676 | Go to err_unlock |
11679 | Attach a performance event to a context.* Very similar to event_function_call, see comment there. |
11680 | perf_unpin_context(ctx) |
11683 | Return event |
11685 | err_unlock : |
11687 | perf_unpin_context(ctx) |
11689 | err_free : |
