[Xen-devel] [PATCH 0/4] AMD IOMMU: misc adjustments


  • To: "xen-devel" <xen-devel@xxxxxxxxxxxxx>
  • From: "Jan Beulich" <JBeulich@xxxxxxxx>
  • Date: Fri, 15 Feb 2013 16:13:17 +0000
  • Delivery-date: Fri, 15 Feb 2013 16:15:53 +0000
  • List-id: Xen developer discussion <xen-devel.lists.xen.org>

This is to improve dealing with systems that have incorrect ACPI
tables, an erratum workaround ported over from Linux, and a
little bit of cleanup.

1: don't BUG() when we don't have to
2: cover all functions of a device even if ACPI only tells us of func 0
3: Family15h Model10-1Fh erratum 746 Workaround
4: use __ioapic_read_entry() instead of open coding it
