Subject: Mapping of PrpList in NvmExpressDxe
Date: Fri, 17 Feb 2017 19:24:03 +0530 [thread overview]
Message-ID: <CAPO=kN2NB6Fi1_zx+WgEaJpR_vN35qc+po12yd4mt_tbVjq2NA@mail.gmail.com> (raw)
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 ?
Regards,
Arka
