From 89a4419cc384c090b1eabe610647aa4e14436a3f Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 25 Mar 2010 04:01:33 -0700 Subject: [PATCH] Add support for new clocks. Recent Linux kernels added support for the CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, and CLOCK_MONOTONIC_COARSE clocks. --- ChangeLog | 11 +++++++++++ bits/time.h | 8 +++++++- sysdeps/unix/sysv/linux/clock_getres.c | 8 +++++++- sysdeps/unix/sysv/linux/clock_gettime.c | 5 ++++- sysdeps/unix/sysv/linux/clock_settime.c | 5 +++-- 5 files changed, 32 insertions(+), 5 deletions(-) diff --git a/ChangeLog b/ChangeLog index 08db020060..6029367106 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,16 @@ +2010-03-24 Ulrich Drepper + + [BZ #11389] + * bits/time.h: Define CLOCK_MONOTONIC_RAW, CLOCK_REALTIME_COARSE, and + CLOCK_MONOTONIC_COARSE. + * sysdeps/unix/sysv/linux/clock_getres.c: Handle CLOCK_MONOTONIC_RAW, + CLOCK_REALTIME_COARSE, and CLOCK_MONOTONIC_COARSE. + * sysdeps/unix/sysv/linux/clock_gettime.c: Likewise. + * sysdeps/unix/sysv/linux/clock_settime.c: Likewise. + 2010-03-16 Chris Demetriou + [BZ #11394] * locale/programs/simple-hash.c: Include inttypes.h.
