Data Fields
struct cyclecounter *	cc
cycle_t	cycle_last
u64	nsec

Detailed Description

struct timecounter - layer above a struct cyclecounter which counts nanoseconds Contains the state needed by timecounter_read() to detect cycle counter wrap around. Initialize with timecounter_init(). Also used to convert cycle counts into the corresponding nanosecond counts with timecounter_cyc2time(). Users of this code are responsible for initializing the underlying cycle counter hardware, locking issues and reading the time more often than the cycle counter wraps around. The nanosecond counter will only wrap around after ~585 years.

: the cycle counter used by this instance : most recent cycle counter value seen by timecounter_read() : continuously increasing count
