Linux kernel source tree

After a PCIe device has established a secure link and session between a TEE Security Manager (TSM) and its local Device Security Manager (DSM), the device or its subfunctions are candidates to be bound to a private memory context, a TVM. A PCIe device function interface assigned to a TVM is a TEE Device Interface (TDI). The pci_tsm_bind() requests the low-level TSM driver to associate the device with private MMIO and private IOMMU context resources of a given TVM represented by a @kvm argument. A device in the bound state corresponds to the TDISP protocol LOCKED state and awaits validation by the TVM. It is a 'struct pci_tsm_link_ops' operation because, similar to IDE establishment, it involves host side resource establishment and context setup on behalf of the guest. It is also expected to be performed lazily to allow for operation of the device in non-confidential "shared" context for pre-lock configuration.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
