Can we get a real help text here: Clock & Timer Selection > 1. Legacy Timer Support (LEGACY_TIMER) (NEW) 2. HPET Timer Support (HPET_TIMER) 3. High Resolution Timer Support (HIGH_RES_TIMERS) (NEW) choice[1-3?]: ? You may have either HPET, High Resolution, or Legacy timer support. This would be a great place to put some of your extensive docs about the various timer sources and issues on x86. I have always thought the HRT docs were the best source on the net for this info, and I refer people to it whenever someone has a question about timers on the linux audio lists. The docs for "High Resolution Timer clock source" are great. Can we get more docs here: HRT Softirg dynamic priority adjustment (HIGH_RES_TIMERS_DYN_PRIO) ^^^ typo [N/y/?] (NEW) ? This option enables the dynamic priority adjustment of the high resolution timer soft interrupt No point documenting this one if it's expected to go away though. Lee
