I had an off-list discussion about concurrent access to SCMI shared memory regions with the Arm SCMI spec[1] maintainer yesterday. An upcoming new version of the Arm SCMI spec will provide a generic, more powerful way to handle concurrent access to shared memory. Therefore, I plan to again drop the requirements introduced in v4 in the upcoming virtio SCMI spec patch v5.
