When configured, certain system 2620730Smckusickstatistics and, optionally, system profiling work 2720730Smckusickwill be collected each time the clock interrupts. For 2847674Scaeloptimum accuracy in profiling, the 2947674Scael.Tn DL-11W 3047674Scaelshould be 3120730Smckusickconfigured to interrupt at the highest possible priority 3220730Smckusicklevel. The 3347674Scael.Nm kg 3420730Smckusickdevice driver automatically calibrates itself to the 3520730Smckusickline clock frequency. 3647674Scael.Sh SEE ALSO 3747674Scael.Xr kgmon 8 , 3847674Scael.Xr config 8 3947674Scael.Sh HISTORY 4047674ScaelThe 4147674Scael.Nm 4247674Scaeldriver appeared in 4347674Scael.Bx 4.2 . 44
