+idpf Linux* Base Driver for the Intel(R) Infrastructure Data Path Function
+==========================================================================
+
+Intel idpf Linux driver.
+Copyright(C) 2023 Intel Corporation.
+
+.. contents::
+
+The idpf driver serves as both the Physical Function (PF) and Virtual Function
+(VF) driver for the Intel(R) Infrastructure Data Path Function.
+
+Driver information can be obtained using ethtool, lspci, and ip.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel adapter. All hardware requirements listed apply to use
+with Linux.
+
+
+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Additional Features and Configurations
+======================================
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. If you don't have one yet, you can
+obtain it at:
+https://kernel.org/pub/software/network/ethtool/
+
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+ # dmesg -n 8
+
+.. note::
+ This setting is not saved across reboots.
+
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ip command to increase the MTU size. For example, enter the following
+where <ethX> is the interface number::
+
+ # ip link set mtu 9000 dev <ethX>
+ # ip link set up dev <ethX>
+
+.. note::
+ The maximum MTU setting for jumbo frames is 9706. This corresponds to the
+ maximum jumbo frame size of 9728 bytes.
+
+.. note::
+ This driver will attempt to use multiple page sized buffers to receive
+ each jumbo packet. This should help to avoid buffer starvation issues when
+ allocating receive packets.
+
+.. note::
+ Packet loss may have a greater impact on throughput when you use jumbo
+ frames. If you observe a drop in performance after enabling jumbo frames,
+ enabling flow control may mitigate the issue.
+
+
+Performance Optimization
+========================
+Driver defaults are meant to fit a wide variety of workloads, but if further
+optimization is required, we recommend experimenting with the following
+settings.
+
+
+Interrupt Rate Limiting
+-----------------------
+This driver supports an adaptive interrupt throttle rate (ITR) mechanism that
+is tuned for general workloads. The user can customize the interrupt rate
+control for specific workloads, via ethtool, adjusting the number of
+microseconds between interrupts.
+
+To set the interrupt rate manually, you must disable adaptive mode::
+
+ # ethtool -C <ethX> adaptive-rx off adaptive-tx off
+
+For lower CPU utilization:
+ - Disable adaptive ITR and lower Rx and Tx interrupts. The examples below
+ affect every queue of the specified interface.
+
+ - Setting rx-usecs and tx-usecs to 80 will limit interrupts to about
+ 12,500 interrupts per second per queue::
+
+ # ethtool -C <ethX> adaptive-rx off adaptive-tx off rx-usecs 80
+ tx-usecs 80
+
+For reduced latency:
+ - Disable adaptive ITR and ITR by setting rx-usecs and tx-usecs to 0
+ using ethtool::
+
+ # ethtool -C <ethX> adaptive-rx off adaptive-tx off rx-usecs 0
+ tx-usecs 0
+
+Per-queue interrupt rate settings:
+ - The following examples are for queues 1 and 3, but you can adjust other
+ queues.
+
+ - To disable Rx adaptive ITR and set static Rx ITR to 10 microseconds or
+ about 100,000 interrupts/second, for queues 1 and 3::
+
+ # ethtool --per-queue <ethX> queue_mask 0xa --coalesce adaptive-rx off
+ rx-usecs 10
+
+ - To show the current coalesce settings for queues 1 and 3::
+
+ # ethtool --per-queue <ethX> queue_mask 0xa --show-coalesce
+
+
+
+Virtualized Environments
+------------------------
+In addition to the other suggestions in this section, the following may be
+helpful to optimize performance in VMs.
+
+ - Using the appropriate mechanism (vcpupin) in the VM, pin the CPUs to
+ individual LCPUs, making sure to use a set of CPUs included in the
+ device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
+
+ - Configure as many Rx/Tx queues in the VM as available. (See the idpf driver
+ documentation for the number of queues supported.) For example::
+
+ # ethtool -L <virt_interface> rx <max> tx <max>
+
+
+Support
+=======
+For general information, go to the Intel support website at:
+http://www.intel.com/support/
+
+If an issue is identified with the released source code on a supported kernel
+with a supported adapter, email the specific information related to the issue
+to intel-wired-lan@lists.osuosl.org.

+TDX Guest API Documentation
+===================================================================
+
+1. General description
+======================
+
+The TDX guest driver exposes IOCTL interfaces via the /dev/tdx-guest misc
+device to allow userspace to get certain TDX guest-specific details.
+
+2. API description
+==================
+
+In this section, for each supported IOCTL, the following information is
+provided along with a generic description.
+
+:Input parameters: Parameters passed to the IOCTL and related details.
+:Output: Details about output data and return value (with details about
+ the non common error values).
+
+2.1 TDX_CMD_GET_REPORT0
+-----------------------
+
+:Input parameters: struct tdx_report_req
+:Output: Upon successful execution, TDREPORT data is copied to
+ tdx_report_req.tdreport and return 0. Return -EINVAL for invalid
+ operands, -EIO on TDCALL failure or standard error number on other
+ common failures.
+
+The TDX_CMD_GET_REPORT0 IOCTL can be used by the attestation software to get
+the TDREPORT0 (a.k.a. TDREPORT subtype 0) from the TDX module using
+TDCALL[TDG.MR.REPORT].
+
+A subtype index is added at the end of this IOCTL CMD to uniquely identify the
+subtype-specific TDREPORT request. Although the subtype option is mentioned in
+the TDX Module v1.0 specification, section titled "TDG.MR.REPORT", it is not
+currently used, and it expects this value to be 0. So to keep the IOCTL
+implementation simple, the subtype option was not included as part of the input
+ABI. However, in the future, if the TDX Module supports more than one subtype,
+a new IOCTL CMD will be created to handle it. To keep the IOCTL naming
+consistent, a subtype index is added as part of the IOCTL CMD.
+
+Reference
+---------
+
+TDX reference material is collected here:
+
+https://www.intel.com/content/www/us/en/developer/articles/technical/intel-trust-domain-extensions.html
+
+The driver is based on TDX module specification v1.0 and TDX GHCI specification v1.0.

For coherent DMA allocation, the DMA buffer gets converted on the
allocation. Check force_dma_unencrypted() for details.
+Attestation
+===========
+
+Attestation is used to verify the TDX guest trustworthiness to other
+entities before provisioning secrets to the guest. For example, a key
+server may want to use attestation to verify that the guest is the
+desired one before releasing the encryption keys to mount the encrypted
+rootfs or a secondary drive.
+
+The TDX module records the state of the TDX guest in various stages of
+the guest boot process using the build time measurement register (MRTD)
+and runtime measurement registers (RTMR). Measurements related to the
+guest initial configuration and firmware image are recorded in the MRTD
+register. Measurements related to initial state, kernel image, firmware
+image, command line options, initrd, ACPI tables, etc are recorded in
+RTMR registers. For more details, as an example, please refer to TDX
+Virtual Firmware design specification, section titled "TD Measurement".
+At TDX guest runtime, the attestation process is used to attest to these
+measurements.
+
+The attestation process consists of two steps: TDREPORT generation and
+Quote generation.
+
+TDX guest uses TDCALL[TDG.MR.REPORT] to get the TDREPORT (TDREPORT_STRUCT)
+from the TDX module. TDREPORT is a fixed-size data structure generated by
+the TDX module which contains guest-specific information (such as build
+and boot measurements), platform security version, and the MAC to protect
+the integrity of the TDREPORT. A user-provided 64-Byte REPORTDATA is used
+as input and included in the TDREPORT. Typically it can be some nonce
+provided by attestation service so the TDREPORT can be verified uniquely.
+More details about the TDREPORT can be found in Intel TDX Module
+specification, section titled "TDG.MR.REPORT Leaf".
+
+After getting the TDREPORT, the second step of the attestation process
+is to send it to the Quoting Enclave (QE) to generate the Quote. TDREPORT
+by design can only be verified on the local platform as the MAC key is
+bound to the platform. To support remote verification of the TDREPORT,
+TDX leverages Intel SGX Quoting Enclave to verify the TDREPORT locally
+and convert it to a remotely verifiable Quote. Method of sending TDREPORT
+to QE is implementation specific. Attestation software can choose
+whatever communication channel available (i.e. vsock or TCP/IP) to
+send the TDREPORT to QE and receive the Quote.

+ * Add that to our base aligned max_data (12K) and we have

+ * 13784 = 12K + (4096-2600)
+ *
+ * After guaranteeing the first chunk ends on a 4K boundary, we

+ * @compl_tag_gen_s: Completion tag generation bit
+ * The format of the completion tag will change based on the TXQ

+ * 15 13 12 0
+ * --------------------------------
+ * |GEN | IDX = 0-8159 |

+ * macros are designed to safely implement stopping
+ * and waking netdev queues without full lock protection.
+ *
+ * We assume that there can be no concurrent stop attempts and no concurrent
+ * wake attempts. The try-stop should happen from the xmit handler,
+ * while wake up should be triggered from NAPI poll context.
+ * The two may run concurrently (single producer, single consumer).
+ *
+ * The try-stop side is expected to run from the xmit handler and therefore
+ * it does not reschedule Tx (netif_tx_start_queue() instead of
+ * netif_tx_wake_queue()). Uses of the ``stop`` macros outside of the xmit
+ * handler may lead to xmit queue being enabled but not run.
+ * The waking side does not have similar context restrictions.
+ *
+ * The macros guarantee that rings will not remain stopped if there's
+ * space available, but they do *not* prevent false wake ups when
+ * the ring is full! Drivers should check for ring full at the start
+ * for the xmit handler.
+ *
+ * All descriptor ring indexes (and other relevant shared state) must
+ * be updated before invoking the macros.

+This document provides guidance on how to change the protos used in this directory.
+
+Any change made to a proto file require to reformat it and regenerate nanopb
+sources. It also requires the proto files to be compatible to previously released versions.
+
+To reformat any proto file run: "clang-format -style=Google -i <file.proto>"
+
+To regenerate nanopb files:
+ - Install protoc
+ - apt-get install protobuf-compiler
+ - Clone/setup nanopb for version 0.3.9.1 (or clone the internal depot)
+ - git clone --depth=1 https://github.com/nanopb/nanopb.git
+ - cd nanopb
+ - git fetch --tags
+ - git checkout tags/0.3.9.1
+ - make -C generator/proto
+ - Run protoc with the nanopb definition
+ - protoc --plugin=<path_to_nanopb>/generator/protoc-gen-nanopb --nanopb_out=<path_to_linux>/security/container/protos/ <path_to_linux>/security/container/protos/<file.proto> --proto_path=<path_to_linux>/security/container/protos
