SubjectRe: [PATCH] Make Intel 8-way Xeons boot again
From
if the system can not use logical flat.

should have some bit set in FADT...

static int physflat_acpi_madt_oem_check(char *oem_id, char *oem_table_id)
{
#ifdef CONFIG_ACPI
/*
* Quirk: some x86_64 machines can only use physical APIC mode
* regardless of how many processors are present (x86_64 ES7000
* is an example).
*/
if (acpi_gbl_FADT.header.revision >= FADT2_REVISION_ID &&
(acpi_gbl_FADT.flags & ACPI_FADT_APIC_PHYSICAL)) {
printk(KERN_DEBUG "system APIC only can use physical flat");
return 1;
}
#endif
return 0;
}
