Hi! I still haven't put up a new NFS server so I'd like you to give this a test run. I noticed that printk() (with timestamps enabled) only prints timestamps with a resolution of 10msec. This is obviously HZ-related and indeed, sched_clock() is used, which just returns jiffies (converted to nsec resolution). This patch adds the Intervall Counter Register value (after subtracting NICR and multiplying the result with 1000 because we're "only" running at 1usec, not 1nsec...) On my KA43, this doesn't make much of a difference because ICR always reads as zero... Could somebody test that on a different box (KA42, KA46, SIMH...)? diff --git a/arch/vax/kernel/time.c b/arch/vax/kernel/time.c index 4204fe0..df3f400 100644 --- a/arch/vax/kernel/time.c +++ b/arch/vax/kernel/time.c @@ -32,7 +32,8 @@ spinlock_t rtc_lock = SPIN_LOCK_UNLOCKED; extern unsigned long wall_jiffies; /* kernel/timer.c */ -#define TICK_SIZE (tick_nsec / 1000) +#define TICK_SIZE (tick_nsec / 1000) +#define NICR_START (0xffffffff - 1000000/HZ) /* last time the cmos clock got updated */ static long last_rtc_update; @@ -73,7 +74,7 @@ void __init time_init(void) * to get more than one interrupt per hour:-) */ if (mv->nicr_required) - __mtpr(0xffffffff - 1000000/HZ, PR_NICR); + __mtpr(NICR_START, PR_NICR); /* Set the clock ticking and enable clock interrupts */ __mtpr(ICCS_ERROR | ICCS_INTERRUPT | /* clear error and interrupt bits */ @@ -334,6 +335,7 @@ unsigned long get_cmos_time(void) */ unsigned long long sched_clock(void) { - return (unsigned long long)jiffies * (1000000000 / HZ); + return (unsigned long long)jiffies * (1000000000 / HZ) + + (__mfpr (PR_ICR) - NICR_START) * 1000; } MfG, JBG -- Jan-Benedict Glaw jbglaw@lug-owl.de . +49-172-7608481 _ O _ "Eine Freie Meinung in einem Freien Kopf | Gegen Zensur | Gegen Krieg _ _ O für einen Freien Staat voll Freier Bürger" | im Internet! | im Irak!
