Hi all,
I'm running a single-CPU Linux VM on Hyper-V. The Linux kernel is v5.9-rc7
and I have CONFIG_NR_CPUS=256.
The Hyper-V Host (Version 17763-10.0-1-0.1457) provides a guest firmware,
which always reports 128 Local APIC entries in the ACPI MADT table. Here
only the first Local APIC entry's
6 matches
