The number of DMA fault reasons in intel's document are from 1 to 0xD, but in dmar.c fault reason 0xD is not printed out. In this document: "Intel Virtualization Technology for Directed I/O Architecture Specification" http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf Chapter 4. Support For Device-IOTLBs Table 6. Unsuccessful Translated Requests There is fault reason for 0xD not listed in kernel: Present context-entry used to process translation request specifies blocking of Translation Requests (Translation Type (T) field value not equal to 01b). This patch adds reason 0xD as well.
