The interfaces picked for N2 PIU performance counters are syntactically identical to those for Fire. The only difference is that the register IDs correspond to different platform-specific registers. This kind of interface means that for every new platform there will be two new fasttraps introduced. If feasible, I suggest a more generic interface with another argument to specify the platform. When this arg specifies platform X, register ID 0 would mean one thing, and if it specifies platform Y reg ID 0 would map to something else. This would save the need for new fasttraps for each platform. Comments?

I believe that we'd like the API versioning information to inform "zeus" explicitly which processor/platform/chipsets the guest is tied to at any given time via the API group#. Ash can chime in if he thinks that is important. Plus, IMHO, it's cleaner to keep the cpu/processor/platform APIs separate from each other.

Adding a cpu-id and defining the register number args still requires a case either way and will raise some other issues. For example, having them separate and in their own API group means they are extensible or changeable using the versioning API, but I'm not sure how to apply the versioning API to a matrix of cpu-specific interfaces without another versioning method specific to that type of API. There are many ways to do that, but they each have their own positive and negative points. If the project team wants to change it, that's fine by me, or they can elect to do something different for VF or ROCK, or they can continue to do what they are doing now. -David Jack Schwartz wrote: > > HI everyone. > > The interfaces picked for N2 PIU performance counters are syntactically > identical to those for Fire.
