I am currently trying to fix an issue with Zephyr running as UOS.
The default configuration of Zephyr for acrn enables the LOAPIC timer,
but there does not seem to be any mention of such timer in acrn. Unless
I am missing something.
When running zephyr with such timer, the timing get all bogus. 60
seconds looks like 5 seconds, etc... Timings are all off.
As HPET is supported by acrn, I switched the timer to HPET. But now I
have a new issue, acrn-dm displays:
hpet t0 configured invalid irq 2, allowed_irqs 0xff000000
And nothing proceeds, since acrn defaults to 0, zephyr isr for hpet is
Indeed Zephyr sets HPET IRQ to 2, which seems to be wrong then for acrn
Which IRQ should HPET timer be configured to use on UOS side then?
