Question about STOR_PERF_DPC_REDIRECTION

Hi All,
I am going through a driver code that clears the STOR_PERF_DPC_REDIRECTION flag in PERF_CONFIGURATION_DATA of storport. Does it mean that the DPC routines will only run on one (assigned) CPU? What if I have 3 different DPCs? Will they run on the same CPU or each can run concurrently on other CPUs?

Is there some documentation about this.
Any information is highly appreciated.

Thanks
Ajitabh

If you set STOR_PERF_DPC_REDIRECTION you get one DPC per-processor. If you
don’t set this flag, you get one DPC per-adapter.
