Name:k_switch_to_oneshot - switch to oneshot mode

Proto:int tick_switch_to_oneshot(void (*handler)(struct clock_event_device *))

Type:int

Parameter:

TypeParameterName
void (*handler
75  td = this_cpu_ptr( & Tick devices)
76  dev = evtdev
78  If Not dev || Not (features & CLOCK_EVT_FEAT_ONESHOT) || Not tick_device_is_functional(dev) Then
81  pr_info("Clockevents: could not switch to one-shot mode:")
82  If Not dev Then
83  Like KERN_CONT, pr_cont() should only be used when continuing* a line with no newline ('\n') enclosed. Otherwise it defaults* back to KERN_DEFAULT.(" no tick device\n")
84  Else
85  If Not tick_device_is_functional(dev) Then Like KERN_CONT, pr_cont() should only be used when continuing* a line with no newline ('\n') enclosed. Otherwise it defaults* back to KERN_DEFAULT.(" %s is not functional.\n", name)
87  Else Like KERN_CONT, pr_cont() should only be used when continuing* a line with no newline ('\n') enclosed. Otherwise it defaults* back to KERN_DEFAULT.(" %s does not support one-shot mode.\n", name)
