Subject2.6.18 and tsc clocksource on SMP
Hello,

I have just upgraded kernel (2.6.16.x->2.6.18.1) on on of my servers (Dell
PowerEdge1425SC with 2 CPUs with HT - total 4 CPUs) and noticed that
system no longer uses HPET as a clocksource.

# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
acpi_pm jiffies hpet tsc pit

# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
tsc

AFAIK TSC should not be used on SMP systems, shouldn't it?

Best regards,


Krzysztof Olędzki
