--- Comment #1 from John Baldwin <j...@freebsd.org> ---
It does not. It uses the flexible array of pointers per guest. However, it
defaults to being limited to the number of physical CPUs on the host the same
as on amd64. There is a tunable to configure it in sys/arm64/vmm/vmm.c:
/*
* Upper limit on vm_maxcpu. We could increase this to 28 bits, but this
* is a safe value for now.
*/
#define VM_MAXCPU MIN(0xffff - 1, CPU_SETSIZE)
...
static int
vmm_init(void)
{
int error;
vm_maxcpu = mp_ncpus;
TUNABLE_INT_FETCH("hw.vmm.maxcpu", &vm_maxcpu);
if (vm_maxcpu > VM_MAXCPU) {
printf("vmm: vm_maxcpu clamped to %u\n", VM_MAXCPU);
vm_maxcpu = VM_MAXCPU;
}
if (vm_maxcpu == 0)
vm_maxcpu = 1;
error = vmm_regs_init(&vmm_arch_regs, &vmm_arch_regs_masks);
if (error != 0)
return (error);
return (vmmops_modinit(0));
}
