Pcie physical function virtual function
SpletSVA is what PCIe calls Shared Virtual Memory (SVM). In addition to the convenience of using application virtual addresses by the device, it also doesn’t require pinning pages for DMA. PCIe Address Translation Services (ATS) along with Page Request Interface (PRI) allow devices to function much the same way as the CPU handling application page ... SpletAs shown in the figure above, the SSD acts as an Endpoint for PCIe, implements a physical function (PF), and has four virtual functions (VF) associated with the PF. Each VF has its own exclusive NS, and the public NS (NS E). This feature allows virtual functions to share physical devices and perform I/O without CPU and hypervisor software overhead.
