Hi. I am working with a platform that has a problem with the RTC alarm interrupt - tested with rtctest from /Documentation/rtc.txt. So I thought that I could use the HPET emulation. As far as I understand in the HPET emulation mode no RTC irq will be used --> RTC alarm interrupt is done via HPET. Is this a correct assumption?
