https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212782 --- Comment #6 from commit-hook@freebsd.org --- A commit references this bug: Author: rgrimes Date: Sat May 4 13:43:49 UTC 2019 New revision: 347124 URL: https://svnweb.freebsd.org/changeset/base/347124 Log: MFC: r346715: Acpi MADT table correction for VM_MAXCPU > 21 The bhyve acpi MADT table was given a static space of 256 (0x100) bytes, this is enough space to allow VM_MAXCPU to be 21, this patch changes that so VM_MAXCPU can be of arbitrary value and not overflow the space by actually calculating the space needed for the table.
