that's the old interface
it's incompatible, deactivate it. look at my config!
( zcat config.gz | grep -i rtc )
see src/Documentation/rtc.txt for more info
# CONFIG_RTC is not set
# CONFIG_GEN_RTC is not set
# CONFIG_HPET_RTC_IRQ is not set
1024 is ok too.
for the new interface however, there doesn't seem to be a sysctl
option anymore/yet and one has to set it manually.
you should
then have a device
/dev/rtc0
I have /dev/rtc from previous
then change the max-user-frequency of rtc (default is only 64):
echo 2048 > /sys/class/rtc/rtc0/max_user_freq
I have this set to 1024 (kernel hz?) in /etc/sysctl.conf.
One caveat is that hal kicks out all the dma and
32-bit disk
accesses but they can be immediately set back so I put that in my startup
stuff as well.
how do you set it up?
can/should that be done with any drive?
any conditions?
