The command ID is in cmd[0], not cmd[1].
pls add a reference to the spec,

Figure 43 "Generic Command Buffer Entry Format" in
https://docs.amd.com/v/u/en-US/48882_3.10_PUB
But the switch() above also uses cmd[0]:
switch (extract64(cmd[0], 60, 4)) {
case AMDVI_CMD_COMPLETION_WAIT:
amdvi_completion_wait(s, cmd);
break;
It has no effect on the guest, only on the -trace option. It may be
confusing to developers if the actual command ID doesn't match what is
shown by -trace.
