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 ?
It cannot be inferred from that statement that PASID support is not
required for SVM. AIUI, SVM is a software feature enabled by numerous
"optional" hardware features, including PASID. Features that are
optional per the hardware specification may be required for specific
software features. Thanks,
Thanks for the information Alex. Suppose if an End point doesn't support
PASID, is it still possible to achieve SVM ?
Are there any such features in SMMUv3 with which we can achieve it ?
