Subject: [PATCH] pps: kc: fix non-tickless system config dependency
Date: Sat, 05 Mar 2016 18:37:39 +0100 [thread overview]
Message-ID: <56DB1963.60808@maciej.szmigiero.name> (raw)
CONFIG_NO_HZ currently only sets the default value
of dynticks config so if PPS kernel consumer needs
periodic timer ticks it should depend on
!CONFIG_NO_HZ_COMMON instead of !CONFIG_NO_HZ.
Otherwise it is possible to enable it even on
tickless system which has CONFIG_NO_HZ not set and
CONFIG_NO_HZ_IDLE (or CONFIG_NO_HZ_FULL) set.

This option adds support for direct in-kernel time
synchronization using an external PPS signal.
