Subject: [Qemu-devel] [PATCH] nvdimm acpi: fix region format interface code
Date: Wed, 7 Jun 2017 16:06:39 +0800 [thread overview]
Message-ID: <20170607080639.22120-1-haozhong.zhang@intel.com> (raw)
Per ACPI 6.2, section 5.2.25.6 and JEDEC Annex L Release 3, the
current region format interface code 0x201 indicates the block
addressed function interface 1, rather than a byte addressable
interface. Fix it by using 0x301 which indicates the byte addressable
no energy backed function interface 1.
