A client in the SOF context is a device that needs to communicate with the DSP via IPC messages. The SOF core is responsible for serializing the IPC messages to the DSP from the different clients. One example of an SOF client would be an IPC test client that floods the DSP with test IPC messages to validate if the serialization works as expected. Multi-client support will also add the ability to split the existing audio cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated client instead of adding HDMI to all cards.
