Dpci-endpoint.txt4 This document is a guide to use the PCI Endpoint Framework in order to create
6 interface to bind the function driver to the controller driver.
10 Linux has a comprehensive PCI subsystem to support PCI controllers that
11 operates in Root Complex mode. The subsystem has capability to scan PCI bus,
18 add endpoint mode support in Linux. This will help to run Linux in an
25 library, the Endpoint Function library, and the configfs layer to bind the
30 The EPC library provides APIs to be used by the controller that can operate
31 in endpoint mode. It also provides APIs to be used by function driver/library
32 in order to implement a particular endpoint function.

6 When clearing a pte/pmd we are given a choice to notify the event through
11 thing like ATS/PASID to get the IOMMU to walk the CPU page table to access a
12 process virtual address space). There is only 2 cases when you need to notify
16 B) a page table entry is updated to point to a new page (COW, write fault
19 Case A is obvious you do not want to take the risk for the device to write to
22 Case B is more subtle. For correctness it requires the following sequence to
