From 12d4777ac103e14a93328776ec05172931fb7e14 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Tue, 2 Jul 2019 15:12:24 +0100 Subject: [PATCH] usertools: support IOAT device binding In order to allow binding/unbinding of devices for use by the ioat_rawdev, we need to update the devbind script to add a new class of device, and add device ids for the specific HW instances.
