34  * struct clocksource - hardware abstraction for a free running counter
35  *	Provides mostly state-free accessors to the underlying hardware.
38  * @read:		Returns a cycle value, passes clocksource as argument
44  * @maxadj:		Maximum adjustment value to mult (~11%)
45  * @archdata:		Optional arch-specific data
46  * @max_cycles:		Maximum safe cycle value which won't overflow on
50  * @rating:		Rating value for selection (higher is better)
54  *			1-99: Unfit for real use
56  *			100-199: Base level usability.
58  *			200-299: Good.
60  *			300-399: Desired.
62  *			400-499: Perfect
63  *				The ideal clocksource. A must-use where
75  * @cs_last:		Last clocksource value for clocksource watchdog
76  * @wd_last:		Last watchdog value corresponding to @cs_last
136 #define CLOCKSOURCE_MASK(bits) GENMASK_ULL((bits) - 1, 0)
156  * clocksource_khz2mult - calculates mult from khz and shift
158  * @shift_constant:	Clocksource shift factor
161  * multiplier, given the clocksource shift value
169  * clocksource_hz2mult - calculates mult from hz and shift
171  * @shift_constant:	Clocksource shift factor
175  * clocksource shift value
183  * clocksource_cyc2ns - converts clocksource cycles to nanoseconds
193  * XXX - This could use some mult_lxl_ll() asm optimization
