I copied and modified the definition:
config RTAI_SCHED_8254_LATENCY
string "8254 tuning latency (ns)"
default 4700
from i386/Kconfig. But the problem is that in "configure.in" around the
latency value checks there is:
if test "$CONFIG_X86" = y; then
...
fi
Well, at least CONFIG_RTAI_SCHED_8254_LATENCY is useful as general timer
latency value for non-x86 archs as well because they are used indirectly
by the scheduler.
