Heh, looks like you ran into some of the same missing instructions @asahilina ran into... can you rebase the HV stuff and see if any of your changes are still needed there? (FWIW for them to be correct you'd have had to expand the Python side too, but that's done now). |

There was a problem hiding this comment.
What codepath is this used in? I'd prefer to keep the alignment fault '(at least by default) since this is usually a mistake when accessing registers, though I know Apple loves using unaligned 64-bit fields in some protocols. Can we make it a separate wrapper in ProxyUtils, a subclass, or something like that?

TL;DR this can successfully capture Bluetooth HCI commands being transported across the (seemingly) Apple-custom PCIe pipe interface
