+XRTV2 Linux Kernel Driver Overview
+==================================

+
+XRTV2 drivers are second generation `XRT <https://github.com/Xilinx/XRT>`_
+drivers which support `Alveo <https://www.xilinx.com/products/boards-and-kits/alveo.html>`_
+PCIe platforms from Xilinx.
+
+XRTV2 drivers support *subsystem* style data driven platforms where the driver's
+configuration and behavior are determined by the metadata provided by the
+platform (in *device tree* format). Primary management physical function (MPF)
+driver is called **xrt-mgmt**. Primary user physical function (UPF) driver is
+called **xrt-user** and is under development. xrt_driver common APIs are packaged
+into a library module called **xrt-lib**, which is shared by **xrt-mgmt** and
+**xrt-user** (under development).
+
+Driver Modules
+==============
+
+xrt-lib.ko
+----------
+
+xrt-lib is the repository of functions that can potentially be shared between
+xrt-mgmt and xrt-user.
+
+Alveo platform consists of one or more FPGA partitions. Each partition has
+multiple HW peripherals (also referred to as endpoints) and metadata to describe
+the endpoints. This metadata is in flat device tree format. xrt-lib relies on OF
+kernel APIs to un-flatten the metadata and overlay the un-flattened device tree
+nodes to the system base device tree.
+
+xrt-mgmt.ko
+------------
+
+The xrt-mgmt driver is a PCIe device driver driving MPF found on Xilinx's Alveo
+PCIe device. It reads Alveo platform partition metadata and creates one or more
+partitions based on the hardware design. xrt-lib APIs are called to overlay the
+endpoint nodes to the system base tree. Eventually, platform devices are
+generated for each endpoint defined in the partition metadata.
+
+The xrt-mgmt driver uses xrt-lib APIs to manage the life cycle of partitions,
+which, in turn, manages multiple endpoints (platform devices) generated during
+partition creation. This flexibility allows xrt-mgmt.ko and xrt-lib.ko to support
+various HW subsystems exposed by different Alveo shells. The differences among
+these Alveo shells is handled in the endpoint (platform device) drivers.
+See :ref:`alveo_platform_overview`.
+
+The instantiation of a specific endpoint driver is completely data driven based
+on the metadata (in the device tree format). The flattened device tree is stored
+in a xsabin file which is discovered through the PCIe VSEC capability.
+
+
+Driver Object Model
+===================
+
+The system device tree after overlaying Alveo partitions looks like the
+following::
+
+                            +-----------+
+                            |  of root  |
+                            +-----------+
+                                  |
+              +-------------------+-------------------+
+              |                   |                   |
+              v                   v                   v
+      +-------------+      +------------+        +---------+
+      | xrt-part0   |      | xrt-partN  |        |         |
+      |(simple-bus) |  ... |(simple-bus)|        |   ...   |
+      +-------------+      +------------+        +---------+
+              |                   |
+              |                   |
+        +-----+--------+          |
+        |              |          |
+        v              v          v
+  +-----------+  +-----------+  +------------+
+  |ep_foo@123 |..|ep_bar@456 |  | ep_foo@789 |
+  +-----------+  +-----------+  +------------+
+
+partition node
+--------------
+
+The partition node is created and added to the system device tree when the driver
+creates a new partition. It is compatible with ``simple-bus`` which is a
+transparent bus node defined by Linux kernel. The partition node is used for
+translating the address of underneath endpoint to CPU address.
+
+endpoint node
+-------------
+
+During the partition creation, xrt driver un-flattens the partition metadata and
+adds all the endpoint nodes under the partition node to the system device tree.
+Eventually, all the endpoint nodes will be populated by the existing platform
+device and OF infrastructure. This means a platform device will be created for
+each endpoint node. The platform driver will be bound based on the ``compatible``
+property defined in the endpoint node.
+
+.. _alveo_platform_overview:
+
+Alveo Platform Overview
+=======================
+
+Alveo platforms are architected as two physical FPGA partitions: *Shell* and
+*User*. The Shell provides basic infrastructure for the Alveo platform like
+PCIe connectivity, board management, Dynamic Function Exchange (DFX), sensors,
+clocking, reset, and security. DFX, partial reconfiguration, is responsible for
+loading the user compiled FPGA binary.
+
+For DFX to work properly, physical partitions require strict HW compatibility
+with each other. Every physical partition has two interface UUIDs: the *parent*
+UUID and the *child* UUID. For simple single stage platforms, Shell → User forms
+the parent child relationship.
+
+.. note::
+   Partition compatibility matching is a key design component of the Alveo platforms
+   and XRT. Partitions have child and parent relationship. A loaded partition
+   exposes child partition UUID to advertise its compatibility requirement. When
+   loading a child partition, the xrt-mgmt driver matches the parent
+   UUID of the child partition against the child UUID exported by the parent.
+   The parent and child partition UUIDs are stored in the *xclbin* (for the user)
+   and the *xsabin* (for the shell). Except for the root UUID exported by VSEC,
+   the hardware itself does not know about the UUIDs. The UUIDs are stored in
+   xsabin and xclbin. The image format has a special node called Partition UUIDs
+   which define the compatibility UUIDs.
+
+
+The physical partitions and their loading are illustrated below::
+
+           SHELL                               USER
+        +-----------+                  +-------------------+
+        |           |                  |                   |
+        | VSEC UUID | CHILD     PARENT |    LOGIC UUID     |
+        |           o------->|<--------o                   |
+        |           | UUID       UUID  |                   |
+        +-----+-----+                  +--------+----------+
+              |                                 |
+              .                                 .
+              |                                 |
+          +---+---+                      +------+--------+
+          |  POR  |                      | USER COMPILED |
+          | FLASH |                      |    XCLBIN     |
+          +-------+                      +---------------+
+
+
+Loading Sequence
+----------------
+
+The Shell partition is loaded from flash at system boot time. It establishes the
+PCIe link and exposes two physical functions to the BIOS. After the OS boots,
+the xrt-mgmt driver attaches to the PCIe physical function 0 exposed by the Shell
+and then looks for VSEC in the PCIe extended configuration space. Using VSEC, it
+determines the logic UUID of the Shell and uses the UUID to load matching *xsabin*
+file from Linux firmware directory. The xsabin file contains the metadata to
+discover the peripherals that are part of the Shell and the firmware for any
+embedded soft processors in the Shell. The xsabin file also contains Partition
+UUIDs.
+
+The Shell exports a child interface UUID which is used for the compatibility
+check when loading the user compiled xclbin over the User partition as part of DFX.
+When a user requests loading of a specific xclbin, the xrt-mgmt driver reads
+the parent interface UUID specified in the xclbin and matches it with the child
+interface UUID exported by the Shell to determine if the xclbin is compatible with
+the Shell. If the match fails, loading of xclbin is denied.
+
+xclbin loading is requested using the ICAP_DOWNLOAD_AXLF ioctl command. When loading
+a xclbin, the xrt-mgmt driver performs the following *logical* operations:
+
+1. Copy xclbin from user to kernel memory
+2. Sanity check the xclbin contents
+3. Isolate the User partition
+4. Download the bitstream using the FPGA config engine (ICAP)
+5. De-isolate the User partition
+6. Program the clocks (ClockWiz) driving the User partition
+7. Wait for the memory controller (MIG) calibration
+8. Return the loading status back to the caller
+
+`Platform Loading Overview <https://xilinx.github.io/XRT/master/html/platforms_partitions.html>`_
+provides more detailed information on platform loading.
+
+
+xsabin
+------
+
+Each Alveo platform comes packaged with its own xsabin. The xsabin is a trusted
+component of the platform. For format details refer to :ref:`xsabin_xclbin_container_format`
+below. xsabin contains basic information like UUIDs, platform name and metadata in the
+form of flat device tree.
+
+xclbin
+------
+
+xclbin is compiled by end user using
+`Vitis <https://www.xilinx.com/products/design-tools/vitis/vitis-platform.html>`_
+tool set from Xilinx. The xclbin contains sections describing user compiled
+acceleration engines/kernels, memory subsystems, clocking information etc. It also
+contains an FPGA bitstream for the user partition, UUIDs, platform name, etc.
+
+
+.. _xsabin_xclbin_container_format:
+
+xsabin/xclbin Container Format
+------------------------------
+
+xclbin/xsabin is ELF-like binary container format. It is structured as series of
+sections. There is a file header followed by several section headers which is
+followed by sections. A section header points to an actual section. There is an
+optional signature at the end. The format is defined by the header file ``xclbin.h``.
+The following figure illustrates a typical xclbin::
+
+
+           +---------------------+
+           |                     |
+           |       HEADER        |
+           +---------------------+
+           |   SECTION  HEADER   |
+           |                     |

+           |         ...         |
+           |                     |
+           +---------------------+
+           |   SECTION  HEADER   |
+           |                     |
+           +---------------------+
+           |       SECTION       |
+           |                     |
+           +---------------------+
+           |         ...         |
+           |                     |
+           +---------------------+
+           |       SECTION       |
+           |                     |
+           +---------------------+
+           |      SIGNATURE      |
+           |      (OPTIONAL)     |
+           +---------------------+
+
+
+xclbin/xsabin files can be packaged, un-packaged and inspected using an XRT
+utility called **xclbinutil**. xclbinutil is part of the XRT open source
+software stack. The source code for xclbinutil can be found at
+https://github.com/Xilinx/XRT/tree/master/src/runtime_src/tools/xclbinutil
+
+For example, to enumerate the contents of a xclbin/xsabin use the *--info* switch
+as shown below::
+
+
+  xclbinutil --info --input /opt/xilinx/firmware/u50/gen3x16-xdma/blp/test/bandwidth.xclbin
+  xclbinutil --info --input /lib/firmware/xilinx/862c7020a250293e32036f19956669e5/partition.xsabin
+
+Deployment Models
+=================
+
+Baremetal
+---------
+
+In bare-metal deployments, both MPF and UPF are visible and accessible. The
+xrt-mgmt driver binds to MPF. The xrt-mgmt driver operations are privileged and
+available to system administrator. The full stack is illustrated below::
+
+                            HOST

+                 +------------------------+
+
+
+
+Virtualized
+-----------
+
+In virtualized deployments, the privileged MPF is assigned to the host but the
+unprivileged UPF is assigned to a guest VM via PCIe pass-through. The xrt-mgmt
+driver in host binds to MPF. The xrt-mgmt driver operations are privileged and
+only accessible to the MPF. The full stack is illustrated below::
+
+
+                                 ..............
+                  HOST           .    VM      .
