On attempt to use device (or even just try 'cat /dev/hpet'), it is said, that
device is busy. But jack has such option :/
I'm using kernel 2.6.33-rt. I can guess, that under rt kernel i should not use HPET
directly, because it is used by system,
and so, may be referred via 'system'. But even if that, such way could bring some
violations comparing to direct HPET usage.
May be indeed, HPET should be used directly only on non-rt systems?..
Btw, how i specified it: i have jack2 and ladish. Clock is specified via ladiconf. Clock
parameter type is integer; yesterday nedko showed me a patch for jack, fixing this
problem, where i saw order of variants in enumeration (hpet variant is '2').
