I don't think it's useful. The reason I posted this question was to check if this is a bug in silicon or intended behavior. If the latter, I'd suggest to emulate it.The spec doesn't say anything about this, I checked it. IIRC, I came across this behavior when submitted COMPLETION_WAIT command with interrupts off and spin in a while() loop waiting for the mask to be written. The loop never finished, but everything worked as intended if I removed COM_COMPLETION_INTR for the command.Is this behaviour useful in any way ?I'll try to fix this in the next version.
