Subject: Support SVM without PASID
Date: Sat, 8 Jul 2017 22:33:01 +0530 [thread overview]
Message-ID: <a30962a6-2240-9263-96cc-10da1b179fcc@gmail.com> (raw)
Hi,
In SMMUv3 architecture document i see "PASIDs are optional,
configurable, and of a size determined by the minimum
of the endpoint".
So if PASID's are optional and not supported by PCIe end point, how SVM
can be achieved ?
How will the translation for a particular process virtual address is
obtained ?
Regards,
Valmiki
