When APIC IDs are sparse*, in addition to valid LAPIC entries the SRAT is also filled invalid ones for non possible APIC IDs. Fix it by asking machine for all possible APIC IDs instead of wrongly assuming that all APIC IDs in range 0..apic_id_limit are possible. * sparse lapic topology CLI: -smp x,sockets=2,cores=3,maxcpus=6 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> --- hw/i386/acpi-build.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-)
