MovidiusのPCIeドライバ

@Vengineerの戯言 : Twitter
SystemVerilogの世界へようこそ、すべては、SystemC v0.9公開から始まった

OpenVINOのソースコードを覗いてみた(その1)

で出てきた Intel Movidiusの PCIe ドライバも公開されています。

PCIeHostDriver : contains PCIe host drivers (linux based) which are GPLv2.

以下引用するが、Ubuntu 16.04 LTS (Linux Kernel v4.15)でのみビルドテストを行ったと。

NOTE: These drivers have only been tested on Ubuntu 16.04 LTS and only build
      when using Linux kernels v4.15 or above.

For host applications to communicate with the Myriad X PCIe endpoint, the host
requires a Linux PCIe based driver. Under the host/ folder, two Linux kernel
drivers exist:
  - The Myriad X Vision Processor (MXVP) driver exposes the interprocessor
    communication protocol between the host and Myriad X and well as helper
    functions to aid in the creation/sending of commands and accesses to
    PCIe MMIO regions. This driver is not a standalone driver and is intended
    to be built into other drivers.
  - The Myriad X Test Framework (MXTF) driver shows example usages of the MXVP
    driver's functionality. Users execute basic functionality tests from the
    command line and see the results displayed in dmesg.

Myaid X Vision Processor ということは、NCS 2の方ですね。。。

こちらのディレクトリは、serialですね。

Overview
========

This is the PCIe Serial driver for Linux hosts. This driver implements the
protocol needed to communicate with Myriad X devices using the PCIe Serial
driver as well.

The PCIe Serial driver is the one used in the XLink stack when using PCIe as the
the communication channel. In this case, this driver must be loaded before
starting any XLink host application.

MovidiusのXLink用のPCIe Serialドライバ ですね。。。

mxbl - Linux host PCIe Boot driverもありますね。

引用します。
Overview
========

This is the PCIe Boot driver for Linux hosts. This driver allows the host
platform to communicate with the Myriad X device using the protocol designed to
transfer Myriad X application binaries over PCIe before booting.

このPCIe ドライバと OpenVINOの中のMovidiusのコード、なんか、微妙に違うような気がします。
