This patch adds new IOMMU performance event based on
the information in table 74 of the AMD I/O Virtualization Technology
(IOMMU) Specification (Document Id: 4882, Rev 2.62, Feb 2015)
Link:
Current driver makes assumption that device with devid zero is always
included in the range of devices to be managed by IOMMU. However,
certain FW does not include devid zero in IVRS table.
This has caused IOMMU perf driver to fail to initialize.
This patch implements a workaround for this case
Hi Will,
It is ready, in internal review, will be sending it in a day.
