From a22131a223147016041b5e5cd0ae5ab61ef4177e Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 9 Sep 2008 17:55:28 +0200 Subject: [PATCH] AMD IOMMU: allow IO page faults from devices There is a bit in the device entry to suppress all IO page faults generated by a device. This bit was set until now because there was no event logging. Now that there is event logging this patch allows IO page faults from devices to see them in the kernel log.
