The KeIpiGenericCall routine causes the specified routine to run on all processors simultaneously.
BroadcastFunction [in]Pointer to an IpiGenericCall routine. This routine is run on every processor simultaneously.
Context [in]Specifies the value to pass to IpiGenericCall when it is called.
KeIpiGenericCall returns the value that IpiGenericCall returns on the source processor (the processor that called KeIpiGenericCall).
When a driver calls KeIpiGenericCall, the system interrupts every processor and raises the IRQL to IPI_LEVEL (interprocessor interrupt level). Each processor spins on a barrier until all processors have reached the barrier; then, all processors begin calling IpiGenericCall. KeIpiGenericCall waits for all calls to IpiGenericCall to complete before returning.
