Hi Tomasz,

Please find my response inline. One question, are you running Zephyr on standard VM or RT VM? Thanks, Like
-----Original Message-----[Like] LOAPIC is short for local APIC, right? In ACRN, we use LAPIC instead. When running zephyr with such timer, the timing get all bogus. 60 seconds[Like] As I know, zephyr won't do runtime timer calibration. You may need to do the calibration manually, and update the code to the correct timer frequency. [Like] HPET may use IRQ 24~31. As well, HPET calibration is needed, so we recommend you to use the LAPIC timer.
