From 0eca353e7ae75a56d5a10cd1c0ff1f06d89e60e3 Mon Sep 17 00:00:00 2001 From: "Bryant G. Ly" Date: Wed, 25 Apr 2018 16:32:57 -0500 Subject: misc: IBM Virtual Management Channel Driver (VMC) This driver is a logical device which provides an interface between the hypervisor and a management partition. This interface is like a message passing interface. This management partition is intended to provide an alternative to HMC-based system management. VMC enables the Management LPAR to provide basic logical partition functions: - Logical Partition Configuration - Boot, start, and stop actions for individual partitions - Display of partition status - Management of virtual Ethernet - Management of virtual Storage - Basic system management This driver is to be used for the POWER Virtual Management Channel Virtual Adapter on the PowerPC platform. It provides a character device which allows for both request/response and async message support through the /dev/ibmvmc node. Signed-off-by: Bryant G.
