Hi all,
I am confused about what this command should be when a master issue this command to a 2 master system. In this system, there are master 1 and master 2, and both masters have its own caches. Now Master 2 is issuing WriteUnique command to the platform and as defined, master 2 will issue a write command and the data and address will be routed to cache of master 1. What will also need to be completed after the data was written to cache of master 1? Should this data in cache of master 1 need to write back to system memory?
Sincerely,
Terry
