Hi Rajagopal,

Please try the latest code, the acpi_idle driver check will be ignored if ACPI Cstate is not enabled in BIOS.

But you need to be aware that Cstate will not be supported in ACRN in this case.

Hi Rajagopal,

This most likely you didn't enable ACPI Cstate in BIOS. Please double check.

We are working on a patch that bypass acpi_idle/acpi_cpufreq driver checking soon, will keep you posted when it is ready.
