d025574e1d m1n1.hv.HV: Run passive tracers *before* issuing the MMIO write 
E.g. this means tracers run *before* an ASC command gets sent, which
might be relevant if the same memory is used for commands and responses.

a714c74e1a m1n1.utils.Reloadable: Only reload each module once 
This avoids confusion with types changing ID when the same module is
repeatedly reloaded. Now we use the file mtime and only reload things
which have changed since last time, and dependent modules.

ba478f2de5 mini.hv.dcp: Decode common messages 
This accounts for most of the DCP traffic once macOS is booted. I used
a sophisticated side-channel hypervisor timing attack to determine the
message functions [ adding time.sleep(1) ]

6adf0c692c mini.trace.asc: Don't log handled messages 
ASC handlers now return a boolean to indicate whether they successfully
handled the message (True if so). In that case, printing the underlying
mailbox traffic is redundant, so let's hide it.

98076ef693 usb: disable tps6598x interrupts 
Restore the interrupt masks on chainload or HV guest start. The
interrupt mask is not restored on the USB-C port used by the hypervisor.
This prevents an interrupt storm in the guest when the other USB-C port
is exposed to the guest. Both tps6598x share unfortunately an interrupt
line.
