From 8703d6e0fcfdcc9323d5316a443882e790efc1a6 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 30 Mar 2012 16:21:17 -0400 Subject: [PATCH] arch/tile: allow querying cpu module information from the hypervisor This just adds a few more attributes to the information Linux can query from the hypervisor for the /sys/hypervisor/board/ directory, providing part, serial#, revision#, and description for cpu modules (as opposed to the board itself, or any mezzanine boards).
