Hi,

with the old rtc.ko module, there was a /proc/sys/dev/rtc/max-user-freq that could be set. With rtc_cmos.ko (or the new rtc infrastructure in general), I am missing this file. Where can I set the max-user-freq now, or is this obsolete now? (mplayer prefers to have user-freq to be >= 1024.)


Qemu wants something like this too. Both of these really want something
else, which is a high-frequency userspace timer.

What is the best way to do that on modern kernels?

/proc/sys/dev/hpet/max-user-freq? But I notice that some kernels provide both values (my 2.6.15, was where I looked), so maybe the rtc went away.
