Based on ACPI Spec, the memory device (PNP0C80) and nvdimm device is notified by the same interruption: Scope (\_GPE) { Method (_L00) { Notify (\_SB.NVDR, 0x80) // Notify to NVDIMM root device Notify (\_SB.MEM0, 1) // Device Check to Memory Module } } So, it is better to reuse _E03 and only notify NVDIMM device if the hotplug event is triggered on a slot with nvdimm device attached?It's only an example in spec but there isn't requirement to do it that way. So I'd use a separate handler for now (we can always chain calls in future is need arises or merge them together)
No objection. Will do it.
