Re: Using %stick where available



If this Sun Fire v240 is any example:

mainbus0 (root): SUNW,Sun-Fire-V240 (Sun Fire V240): hostid XXXXXXXX
cpu0 at mainbus0: SUNW,UltraSPARC-IIIi @ 1280 MHz, UPA id 0
cpu0: system tick frequency 12 MHz
cpu0: 32K instruction (32 b/l), 64K data (32 b/l), 1024K external (64 b/l)
cpu1 at mainbus0: SUNW,UltraSPARC-IIIi @ 1280 MHz, UPA id 1
cpu1: system tick frequency 12 MHz
cpu1: 32K instruction (32 b/l), 64K data (32 b/l), 1024K external (64 b/l)

which after this amount of time running a patched kernel:

12:55AM  up  5:40, 2 users, load averages: 0.04, 0.01, 0.00

yielded this kind of time keeping:

ntp_gettime() returns code 0 (OK)
  time d444a096.f17e777c  Wed, Nov  7 2012  0:55:50.943, (.943336451),
  maximum error 82652 us, estimated error 922 us, TAI offset 0
ntp_adjtime() returns code 0 (OK)
  modes 0x0 (),
  offset 2568.456 us, frequency 10.600 ppm, interval 4 s,
  maximum error 82652 us, estimated error 922 us,
  status 0x2001 (PLL,NANO),
  time constant 9, precision 0.001 us, tolerance 496 ppm,
  pps frequency 7.359 ppm, stability 0.000 ppm, jitter 0.000 us,
  intervals 0, jitter exceeded 0, stability exceeded 0, errors 0.

(frequency < 10!!)

Commit those patches NOW! Pull them up to netbsd-6 and netbsd-5!
