Subject: [PATCH 0/8] Improved fault handling for AMD-IOMMU (AMD-Vi)
Date: Fri, 4 Sep 2009 11:44:34 +0200 [thread overview]
Message-ID: <1252057482-32207-1-git-send-email-joerg.roedel@amd.com> (raw)
Hi,
this series of patches implements improved fault handling in the AMD-IOMMU
(AMD-Vi) driver. The debug output is more verbose for some errors. With these
patches the driver also tries to recover from IOMMU command handling errors
instead of just do a panic.
Joerg
