+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 driver's
+configuration and behavior are determined by 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 framework and HW subsystem
+drivers are packaged into a library module called **xrt-lib**, which is shared
+by **xrt-mgmt** and **xrt-user** (under development). The xrt_driver framework
+implements a ``bus_type`` called **xrt_bus_type** which is used to discover HW
+subsystems and facilitate inter HW subsystem interaction.
+
+Driver Modules
+==============
+
+xrt-lib.ko
+----------
+
+xrt-lib is the repository of all subsystem drivers and pure software modules that
+can potentially be shared between xrt-mgmt and xrt-user. All these drivers are
+structured as **xrt_driver** and are instantiated by xrt-mgmt (or xrt-user under
+development) based on the metadata associated with the hardware. The metadata is
+in the form of a device tree as mentioned before. Each xrt_driver statically
+defines a subsystem node array by using a node name or a string in its ``.endpoints``
+property. And this array is eventually translated to IOMEM resources in the
+instantiated **xrt_device**.
+
+The xrt-lib infrastructure provides hooks to xrt_drivers for device node
+management, user file operations and ioctl callbacks. The core infrastructure also
+provides a bus functionality called **xrt_bus_type** for xrt_driver registration,
+discovery and inter xrt_driver calls. xrt-lib does not have any dependency on PCIe
+subsystem.
+
+.. note::
+   See code in ``include/xleaf.h`` and ``include/xdevice.h``
+
+
+xrt-mgmt.ko
+------------
+
+The xrt-mgmt driver is a PCIe device driver driving MPF found on Xilinx's Alveo
+PCIe device. It consists of one *root* driver, one or more *group* drivers
+and one or more *xleaf* drivers. The group and xleaf drivers are instantiations
+of the xrt_driver but are called group and xleaf to symbolize the logical operation
+performed by them.
+
+The root driver manages the life cycle of multiple group drivers, which, in turn,
+manages multiple xleaf drivers. 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 xleaf drivers. The root and group
+drivers are part of the infrastructure which provide common services to xleaf
+drivers found on various Alveo shells. See :ref:`alveo_platform_overview`.
+
+The instantiation of specific group driver or xleaf drivers is completely data
+driven based on metadata (mostly in device tree format) found through VSEC
+capability and inside the firmware files, such as platform xsabin or user xclbin
+file.
+
+
+Driver Object Model
+===================
+
+The driver object model looks like the following::
+
+                    +-----------+

+As an example, for Xilinx Alveo U50 before user xclbin download, the tree
+looks like the following::

+
+root
+----
+
+The root driver is a PCIe device driver attached to MPF. It's part of the
+infrastructure of the MPF driver and resides in xrt-mgmt.ko. This driver
+
+* manages one or more group drivers
+* provides access to functionalities that requires pci_dev, such as PCIE config
+  space access, to other xleaf drivers through root calls
+* facilities inter xleaf driver calls for other xleaf drivers
+* facilities event callbacks for other xleaf drivers
+
+When the root driver starts, it will explicitly create an initial group instance,
+which contains xleaf drivers that will trigger the creation of other group
+instances. The root driver will wait for all group and xleaf drivers to be
+created before it returns from its probe routine and claim success of the
+initialization of the entire xrt-mgmt driver. If any xleaf fails to initialize
+the xrt-mgmt driver will still come online but with limited functionality.
+
+.. note::
+   See code in ``lib/xroot.c`` and ``mgmt/root.c``
+
+
+group
+-----
+
+The group driver represents a pseudo device whose life cycle is managed by
+root and does not have real IO mem or IRQ resources. It's part of the
+infrastructure of the MPF driver and resides in xrt-lib.ko. This driver
+
+* manages one or more xleaf drivers
+* provides access to root from xleaf drivers, so that root calls, event
+  notifications and inter xleaf calls can happen
+
+In xrt-mgmt, an initial group driver instance will be created by the root. This
+instance contains xleaf drivers that will trigger group instances to be created
+to manage groups of xleaf drivers found on different partitions of hardware,
+such as VSEC, Shell, and User.
+
+Every *fpga_region* has a group driver associated with it. The group driver is
+created when a xclbin image is loaded on the fpga_region. The existing group
+is destroyed when a new xclbin image is loaded. The fpga_region persists
+across xclbin downloads.
+
+.. note::
+   See code in ``lib/group.c``
+
+
+xleaf
+-----
+
+The xleaf driver is a xrt_driver whose life cycle is managed by
+a group driver and may or may not have real IO mem or IRQ resources. They
+manage HW subsystems they are attached to.
+
+A xleaf driver without real hardware resources manages in-memory states for
+xrt-mgmt. These states are shareable by other xleaf drivers.
+
+Xleaf drivers assigned to specific hardware resources drive a specific subsystem
+in the device. To manipulate the subsystem or carry out a task, a xleaf driver
+may ask for help from the root via root calls and/or from other leaves via
+inter xleaf calls.
+
+A xleaf can also broadcast events through infrastructure code for other leaves
+to process. It can also receive event notification from infrastructure about
+certain events, such as post-creation or pre-exit of a particular xleaf.
+
+.. note::
+   See code in ``lib/xleaf/*.c``
+
+
+xrt_bus_type
+------------
+
+xrt_bus_type defines a virtual bus which handles xrt_driver probe, remove and match
+operations. All xrt_drivers register with xrt_bus_type as part of xrt-lib driver
+``module_init`` and un-register as part of xrt-lib driver ``module_exit``.
+
+.. note::
+   See code in ``lib/lib-drv.c``
+
+FPGA Manager Interaction
+========================
+
+fpga_manager
+------------
+
+An instance of fpga_manager is created by xmgmt_main and is used for xclbin
+image download. fpga_manager requires the full xclbin image before it can
+start programming the FPGA configuration engine via Internal Configuration
+Access Port (ICAP) xrt_driver.
+
+fpga_region
+-----------
+
+For every interface exposed by the currently loaded xclbin/xsabin in the
+*parent* fpga_region a new instance of fpga_region is created like a *child*
+fpga_region. The device tree of the *parent* fpga_region defines the
+resources for a new instance of fpga_bridge which isolates the parent from
+child fpga_region. This new instance of fpga_bridge will be used when a
+xclbin image is loaded on the child fpga_region. After the xclbin image is
+downloaded to the fpga_region, an instance of a group is created for the
+fpga_region using the device tree obtained as part of the xclbin. If this
+device tree defines any child interfaces, it can trigger the creation of
+fpga_bridge and fpga_region for the next region in the chain.
+
+fpga_bridge
+-----------
+
+Like the fpga_region, an fpga_bridge is created by walking the device tree
+of the parent group. The bridge is used for isolation between a parent and
+its child.
+
+Driver Interfaces
+=================
+
+xrt-mgmt Driver Ioctls
+----------------------
+
+Ioctls exposed by the xrt-mgmt driver to user space are enumerated in the
+following table:
+
+== ===================== ============================ ==========================
+#  Functionality         ioctl request code            data format
+== ===================== ============================ ==========================
+1  FPGA image download   XMGMT_IOCICAPDOWNLOAD_AXLF    xmgmt_ioc_bitstream_axlf
+== ===================== ============================ ==========================
+
+A user xclbin can be downloaded by using the xbmgmt tool from the XRT open source
+suite. See example usage below::
+
+  xbmgmt partition --program --path /lib/firmware/xilinx/862c7020a250293e32036f19956669e5/test/verify.xclbin --force
+
+xrt-mgmt Driver Sysfs
+----------------------
+
+The xrt-mgmt driver exposes a rich set of sysfs interfaces. Subsystem xrt
+drivers export sysfs node for every platform instance.
+
+Every partition also exports its UUIDs. See below for examples::
+
+  /sys/bus/pci/devices/0000:06:00.0/xmgmt_main.0/interface_uuids
+  /sys/bus/pci/devices/0000:06:00.0/xmgmt_main.0/logic_uuids
+
+
+hwmon
+-----
+
+The xrt-mgmt driver exposes standard hwmon interface to report voltage, current,
+temperature, power, etc. These can easily be viewed using *sensors* command line
+utility.
+
+.. _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. See :ref:`partition_uuids`.
+
+
+The physical partitions and their loading are illustrated below::
+
+           SHELL                               USER
+        +-----------+                  +-------------------+

+          |  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 as described here :ref:`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.

+------
+
+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 device tree. See :ref:`device_tree_usage` below for details and example.
+
+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
+------------------------------
+
+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::

+
+
+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
+
+
+.. _device_tree_usage:
+
+Device Tree Usage
+-----------------
+
+The xsabin file stores metadata which advertise HW subsystems present in a
+partition. The metadata is stored in device tree format with a well defined
+schema. XRT management driver uses this information to bind *xrt_drivers* to
+the subsystem instantiations. The xrt_drivers are found in **xrt-lib.ko** kernel
+module.
+
+Logic UUID
+^^^^^^^^^^
+A partition is identified uniquely through ``logic_uuid`` property::
+
+  /dts-v1/;
+  / {
+      logic_uuid = "0123456789abcdef0123456789abcdef";
+      ...
+    }
+
+Schema Version
+^^^^^^^^^^^^^^
+Schema version is defined through the ``schema_version`` node. It contains
+``major`` and ``minor`` properties as below::
+
+  /dts-v1/;
+  / {
+       schema_version {
+           major = <0x01>;
+           minor = <0x00>;
+       };
+       ...
+    }
+
+.. _partition_uuids:
+
+Partition UUIDs
+^^^^^^^^^^^^^^^
+Each partition may have parent and child UUIDs. These UUIDs are
+defined by ``interfaces`` node and ``interface_uuid`` property::
+
+  /dts-v1/;
+  / {
+       interfaces {
+           @0 {
+                  interface_uuid = "0123456789abcdef0123456789abcdef";
+           };
+           @1 {
+                  interface_uuid = "fedcba9876543210fedcba9876543210";
+           };
+           ...
+        };
+       ...
+    }
+
+
+Subsystem Instantiations
+^^^^^^^^^^^^^^^^^^^^^^^^
+Subsystem instantiations are captured as children of ``addressable_endpoints``
+node::
+
+  /dts-v1/;
+  / {
+       addressable_endpoints {
+           abc {
+               ...
+           };
+           def {
+               ...
+           };
+           ...
+       }
+  }
+
+Subnode 'abc' and 'def' are the name of subsystem nodes
+
+Subsystem Node
+^^^^^^^^^^^^^^
+Each subsystem node and its properties define a hardware instance::
+
+
+  addressable_endpoints {
+      abc {
+          reg = <0x00 0x1f05000 0x00 0x1000>>
+          pcie_physical_function = <0x0>;
+          pcie_bar_mapping = <0x2>;
+          compatible = "abc def";
+          interrupts = <0x09 0x0c>;
+          firmware {
+              firmware_product_name = "abc"
+              firmware_branch_name = "def"
+              firmware_version_major = <1>
+              firmware_version_minor = <2>
+          };
+      }
+      ...
+  }
+
+:reg:
+ Property defines an address range. `<0x00 0x1f05000 0x00 0x1000>` indicates
+ *0x00 0x1f05000* as BAR offset and *0x00 0x1000* as address length.
+:pcie_physical_function:
+ Property specifies which PCIe physical function the subsystem node resides.
+ `<0x0>` implies physical function 0.
+:pcie_bar_mapping:
+ Property specifies which PCIe BAR the subsystem node resides. `<0x2>` implies
+ BAR 2. A value of 0 means the property is not defined.
+:compatible:
+ Property is a list of strings. The first string in the list specifies the exact
+ subsystem node. The following strings represent other devices that the device
+ is compatible with.
+:interrupts:
+ Property specifies start and end interrupts for this subsystem node.
+ `<0x09 0x0c>` implies interrupts 9 to 13 are used by this subsystem.
+:firmware:
+ Subnode defines the firmware required by this subsystem node.

+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
+
+               [XRT-MGMT]         [XRT-USER]
+                    |                  |
+                    |                  |
+                 +-----+            +-----+
+                 | MPF |            | UPF |
+                 |     |            |     |
+                 | PF0 |            | PF1 |
+                 +--+--+            +--+--+
+          ......... ^................. ^..........
+                    |                  |
+                    |   PCIe DEVICE    |
+                    |                  |
+                 +--+------------------+--+
+                 |         SHELL          |
+                 |                        |
+                 +------------------------+
+                 |         USER           |

+                 |                        |
+                 +------------------------+
+
+
+
+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      .
+                                 .            .
+               [XRT-MGMT]        . [XRT-USER] .
+                    |            .     |      .
+                    |            .     |      .
