Are there any source that I can download ACPI table 2.0+ for QEMU?

503 Views Asked by At

After using SeaBIOS for a while, I realized that it's too old. I want to use ACPI 2.0+ for finding and using HPET instead of PIT and APIC timer. I have searched on Google and I know that I can add additional ACPI table to QEMU, but the problem here is I can't find any source for downloading ACPI. Can anyone suggest me?

qemu-system-x86_64 -M hpet=on should do the trick.

HPET emulation is off by default because of the virtualization overhead. qemu generates acpi tables matching the emulated hardware, so when the HPET is enabled it will also show up in the ACPI tables.
