Provider mapping for old Kernel groups?

I just started getting familiar with the old xperf and the new WPR/WPA toolkit,  couple of questions

1) I was interested in recording interrupt/DPC type traces similar to the older 'latency' kernel group.  I don't understand which Provider captures these same metrics (kernel interrupt, DPC timing) ?

2) When looking at Kernel Interrupts, I am interested in observing which CPU interrupts are being serviced on.  (I am playing with the affinity policy tool and fibre channel interrupts).   is there a Provider that would help me drill down Interrupts by CPU?

Thanks!
