I am wondering what is the reason for mapping the PrpList buffer with EfiPciIoOperationBusMasterCommonBuffer, as host will fill the Prp entries and after updating the submission queue doorbell device will start processing the command and fetch the Prp entries. So I am thinking the Prplist buffer could have been mapped as EfiPciIoOperationBusMasterRead. Is there any reason for mapping it as CommonBuffer that I am not able to figure out ?
