Hello Markus, > But changing driver architecture or implementing my own streaming interface > is not really a solution that I expected to do.... The only solution I have found for PortCls is to restrict affinity of the thread providing IOCTL_KS_READ_STREAM/IOCTL_KS_WRITE_STREAM IRPs to a single CPU (for example, CPU 0). Processing these IRPs, PortCls calls MappingAvailable so you can insert affinity restriction code into this function. Don't forget to save thread ID to an internal list/array to avoid calling affinity set functions every time.
