From e8524f01b12a101381ebf072c8430e8ce49e383d Mon Sep 17 00:00:00 2001 From: Roger Pau Monne Date: Thu, 19 Jun 2014 13:05:54 +0200 Subject: [PATCH v5 05/29] xen: change quality of the MADT ACPI enumerator Lower the quality of the MADT ACPI enumerator, so on Xen Dom0 we can force the usage of the Xen mptable enumerator even when ACPI is detected. This is needed because Xen might restrict the number of vCPUs available to Dom0, but the MADT ACPI table parsed in FreeBSD is the native one (which enumerates all the CPUs available in the system).
