This is caused by an ordering issue # introduced in the recent changes which skip PIT initialization when # the TSC and APIC frequencies are already known. # # - Handle malformed SRAT tables during early ACPI parsing which caused # an infinite loop anda boot hang. # # - Fix a long standing race in the affinity setting code which affects # PCI devices with non-maskable MSI interrupts. The problem is caused # by the non-atomic writes of the MSI address (destination APIC id) # and data (vector) fields which the device uses to construct the MSI # message. The non-atomic writes are mandated by PCI. # # If both fields change and the device raises an interrupt after # writing address and before writing data, then the MSI block # constructs a inconsistent message which causes interrupts to be # lost and subsequent malfunction of the device. # # The fix is to redirect the interrupt to the new vector on the # current CPU first and then switch it over to the new target CPU. # This allows to observe an eventually raised interrupt in the # transitional stage (old CPU, new vector) to be observed in the APIC # IRR and retriggered on the new target CPU and the new vector. # # The potential spurious interrupts caused by this are harmless and # can in the worst case expose a buggy driver (all handlers have to # be able to deal with spurious interrupts as they can and do happen # for various reasons). # # - Add the missing suspend/resume mechanism for the HYPERV hypercall # page which prevents resume hibernation on HYPERV guests. This # change got lost before the merge window. # # - Mask the IOAPIC before disabling the local APIC to prevent # potentially stale IOAPIC remote IRR bits which cause stale # interrupt lines after resume" #
