Subject: do_gettimeofday( ) precision?
Date: Wed, 23 Jun 2004 20:53:29 +0530 [thread overview]
Message-ID: <7c07cd69040623082311234157@mail.gmail.com> (raw)
hello,
the comment on top of do_gettimeofday( ) [arch/i386/kernel/time.c] says:
/*
* This version of gettimeofday has microsecond resolution
* and better than microsecond precision on fast x86 machines with TSC.
*/
void do_gettimeofday(struct timeval *tv)
{
...
but the code below limits usec to <= 1000000. so isn't the resolution
not limited to microsec even on TSC capable boxes?
if one wants higher resolution (for timestamping etc.) whats the preferred
way?
thanks
abhijit
