Questions

Questions I have.

• If we added PIs to PAG, do we need another bit somewhere to clear the interrupt condition?

• Does IBP clear FPD?

• When invalidating the page table cache, why not write entries you read into the cache?

• Which memory reference class is the the byte pointer itself?

• What memory reference class should XCT(RI) use to read the instruction it’s going to execute?

• Does the quantum timer in PAG really only increment when the APR is in PI 0?
