We already have that disabled (well, in 3.10 it depends on BROKEN, and we don't have BROKEN enabled :). However I'm curious why you suggest that. Because some of the devices we're accessing via vfio are in fact Intel DMA engines (we blacklist ioatdma and use the DMA devices directly from userspace). Is there some known interaction between the Intel DMA engines and interrupt remapping? Thanks!
