Keep in mind that we can't allocate any memory during submission or in a reset. I think we should just tell the newly mapped kernel ring to start to from the known good RPTR and process to whatever the current WPTR is. Only after that an IB test should be inserted. We could also modify the conditional code used for MCBP to skip processing for a specific VMID by applying a mask instead of always checking for 0 and 1. Christian.
