^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		(RO) Size of a write request to a DIMM that will not incur a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		read-modify-write cycle at the memory controller.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		When the nfit driver initializes it runs an ARS (Address Range
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		Scrub) operation across every pmem range. Part of that process
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		involves determining the ARS capabilities of a given address
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		range. One of the capabilities that is reported is the 'Clear
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		Uncorrectable Error Range Length Unit Size' (see: ACPI 6.2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		section 9.20.7.4 Function Index 1 - Query ARS Capabilities).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		This property indicates the boundary at which the NVDIMM may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		need to perform read-modify-write cycles to maintain ECC (Error
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		Correcting Code) blocks.
