bus tag is to allow bus space accesses prior to having newbus fully initialized, such as would be the case for console drivers. Since barriers are a fundamental part of bus space accesses, not allowing them on fake tags would defeat the purpose of these tags. We use the barrier function normally associated with nexus. This is the barrier used when subordinates haven't defined a barrier themselves. |
