Subject: [RFC][PATCH v2 02/21] acpi/numa: memorize NUMA node type from SRAT table
Date: Wed, 26 Dec 2018 21:14:48 +0800 [thread overview]
Message-ID: <20181226133351.164047705@intel.com> (raw)
In-Reply-To: 20181226131446.330864849@intel.com
[-- Attachment #1: 0002-acpi-Memorize-numa-node-type-from-SRAT-table.patch --]
[-- Type: text/plain, Size: 1920 bytes --]
From: Fan Du <fan.du@intel.com>
Mark NUMA node as DRAM or PMEM.
This could happen in boot up state (see the e820 pmem type
override patch), or on fly when bind devdax device with kmem
driver.
It depends on BIOS supplying PMEM NUMA proximity in SRAT table,
that's current production BIOS does.
