Userspace code for the Microsemi PCIe switch

Switchtec Management CLI and Library

Summary

The code hosted here provides an easy to use CLI and C library for communicating with Microsemi's Switchtec management interface. It utilizes the switchtec kernel module which, with luck, will be upstream for 4.11. Otherwise it can be obtained from the switchtec-kernel github repository and compiled for other supported kernels.

Currently the following features are supported:

• Show status for each port on all partitions
• Measure bandwidth and latency for each port
• Display and wait on event occurrances
• Setup and show event counters for various types of events
• Dump firmware logs
• Send a hard reset command to the switch
• Update and readback firmware as well as display image version and CRC info
• A simple ncurses GUI that shows salient information for the switch
• Display and configure manufacturing settings

Detailed documentation for the project can be found on the Github Pages site.

Dependencies

This program has an optional build dependencies on the following libraries:

• libncurses5-dev (without it, 'switchtec gui' will not work)
• libssl-dev (without it, some of the commands in 'switchtec mfg' will not work)

Installation

Installation is simple, with:

./configure
make
sudo make install

Building on Windows

MSYS2 should be used to build switchtec-user on windows seeing it provides a reasonably compatible compiler. (Visual C++ still is missing full support of C99.) To setup an environment:

1. Install MSYS2 by following the instructions at: http://www.msys2.org/
2. In an MSYS2 shell, run the following:

pacman -S --needed base-devel mingw-w64-i686-toolchain mingw-w64-x86_64-toolchain git

3. Close the MSYS2 shell, open an MINGW64 shell, checkout the project and follow the above installation instructions as usual.
