PASID is an optional feature that enables sharing of a single Endpoint device across multiple processes while providing each process a complete 64-bit virtual address space. In practice, this feature adds support for a TLP prefix that contains a 20-bit address space that can be added to memory transaction TLPs.

A Process Address Space ID (PASID) is a PCIe-defined Transaction Layer Packet (TLP) prefix. A PASID is a 20-bit number allocated and managed by the OS. PASID is included in all transactions between the platform and the device.

Sep 18, 2023 · PASID(Process Address Space ID) ，地址空间ID，是EP的本地ID，每个function都有一组不同的PASID，不同function间的PASID互不相关。带有PASID的TLP Prefix是一种End-End的TLP前缀，PASID与Requester ID一起共同作为请求TLP地址空间的唯一标识。同一PASID在同一系统中可以重复使用。

Dec 28, 2021 · With the PCIe PASID extension, untranslated addresses can also include a process address space ID (PASID). The IOMMU can take this ID into account when selecting the translation table. For example, this can be used to assign a device to process and have the process use IO virtual addresses with the device.

Sep 18, 2019 · PASID is PCIE standard. Your server chipset platfrom should support IOMMU and enable it on BIOS, also kernel code need support that. That is commen kernel feature. below is the spec of pci sig, and pasid kernel feature from kernel.org. https://pcisig.com/specifications/pciexpress/specifications/ECN-PASID-ATS-2011-03-31.pdf?speclib=pasid

Mar 31, 2011 · The PASID TLP Prefix is an End-End TLP Prefix as defined in the PCI Express Base Specification. Routing elements that support End-End TLP Prefixes (i.e. have the End-End TLP Prefix Supported bit Set in the Device Capabilities 2 register) can correctly forward TLPs containing a PASID TLP Prefix.

Mar 31, 2011 · The Process Address Space ID (PASID) ECN to the Base... view more The Process Address Space ID (PASID) ECN to the Base PCI Express Specification defines the PASID TLP Prefix. This companion ECN is optional normative and defines PASID TLP Prefix usage rules for ATS and PRI.
