Message-ID: <496DEB16.5060803@domain.hid> (raw)
Hi,
I run clocktest on a system here, not running NTP, using
CONFIG_GENERIC_CLOCKEVENT, with a systematic drift of 3us/s. How can
this happen? Does it come from the error due to the multiply and shift
used for tsc to/from ns conversions ?
TIA,

Gilles.
