From 31e09b18c863718939e3e9c30eee55f9011d85ee Mon Sep 17 00:00:00 2001 From: Linda Knippers Date: Tue, 1 Sep 2015 15:41:55 -0400 Subject: [PATCH] x86/mm/srat: Print non-volatile flag in SRAT With the addition of NVDIMM support, a question came up as to whether NVDIMM ranges should be in the SRAT with this bit set. I think the consensus was no because the ranges are in the NFIT with proximity domain information there. ACPI is not clear on the meaning of this bit in the SRAT. If someone is setting it, we might want to ask them what they expect to happen with it. Right now this bit is only printed if all the ACPI debug information is turned on.
