Messages that are sent to platform, also known as commands and can be: 1. Synchronous commands that block the channel until the requested work has been completed. The platform responds to these commands over the same channel and hence can't be used to send another command until the previous command has completed. 2. Asynchronous commands on the other hand, the platform schedules the requested work to complete later in time and returns almost immediately freeing the channel for new commands. The response indicates the success or failure in the ability to schedule the requested work. When the work has completed, the platform sends an additional delayed response message. Using the same transmit buffer used for sending the asynchronous command even for the delayed response corresponding to it simplifies handling of the delayed response. It's the caller of asynchronous command that is responsible for allocating the completion flag that scmi driver can complete to indicate the arrival of delayed response.
