From mboxrd@z Thu Jan 1 00:00:00 1970 From: Shanker Donthineni Subject: [PATCH] ACPI : Update platform device numa node based on _PXM method Date: Tue, 21 Mar 2017 09:54:30 -0500 Message-ID: <1490108070-24061-1-git-send-email-shankerd@codeaurora.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: "Rafael J. Wysocki" , Len Brown Cc: linux-acpi , linux-kernel , Vikram Sethi , Shanker Donthineni List-Id: linux-acpi@vger.kernel.org The optional _PXM method evaluates to an integer that identifies the proximity domain of a device object. This patch implements support for ACPI _PXM method and updates the platform device numa node id using acpi_get_node(), which provides the PXM to NUMA mapping information.
