  "message": "cbdma: overhauled #cbdma\n\nThis uses the dma engine API, and the Linux IOAT driver beneath that.\n\nFor whatever reason, we auto-assign 0:4.3 to the kernel, and that is the\nonly device used by #cbdma/ktest.\n\n\tcat cbdma/ktest \t\t# tests 0:4.3 in the kernel\n\techo 00:04.3 0 \u003e iommu/detach \t# detaches from the kernel\n        echo 00:04.4 PID \u003e iommu/detach # attaches to PID\n        ucbdma 0:4.3 \t\t\t# attach, test, detach\n        ucbdma 0:4.4\n\nucbdma spits out all of the iommu mappings when it runs.  It\u0027s basically\nthe ktest \"do a single memcpy and don\u0027t break anything\" type of test.\ni.e. it doesn\u0027t test stuff like \"can i do a ucbdma without assigning\" or\nwhatnot.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
