Testing under macOS Apple Silicon #137

mcuee · 2021-06-05T10:36:29Z

Sorry but I can not seem to be able to build libusbdotnet under my Mac Mini M1. Just wondering if there is any reference. I have installed Visual Studion for Mac.

My main target is actually to run the examples as I have the associated HW (Benchmark USB device) to carry out the tests. For the old 2.2.8 release (released back in 29-Oct-2010) I can only run the benchmarkcon console application but it is actually the most important app for me. The other GUI examples will just crash.

mcuee · 2021-06-06T10:42:07Z

Right now the examples seem to point to .NET Framework 4.5, and not .Net 5.0, or .NetCore 3.1/5.0.

qmfrederik · 2021-06-07T11:22:04Z

@mcuee "Modern" C#/.NET code should work just fine when compiled for arm/rpi.

This project (still) uses MSBuild.Sdk.Extras, an add-on to the build process, in an attempt to work around some issues which existed when building cross-platform .NET code in the early days of .NET Core.

Updating this has been on my backburner for quite a while (admittedly, too long). Let me see if I can free up time the coming weeks to get this done. It will make things easier for everyone.

The goal still is:

To make the .NET bindings just "tiny" wrappers around the native, C code
Be compatible with the libusb packages which exist for the various platforms
Support all platforms which .NET Core supports
Ship with a compiled version of libusb for platforms which don't ship with libusb

mcuee · 2021-06-07T12:22:27Z

@qmfrederik That will be great. I would like to use BenchmarkCon to test both libusbdotnet and libusb in Windows/Linux/Mac, I did that last time when I was able to build libusbdotnet using SharpDevelop under Windows and MonoDevelop under Linux/Mac.

mcuee · 2021-06-08T12:05:42Z

qmfrederik · 2021-06-08T14:11:11Z

@mcuee Yes, you are correct. The benchmark library uses async transfers which haven't been ported yet to the 3.0 series. That's causing the errors you are seeing.

On a related note - I'd like to add some sort of integration tests to LibUsbDotNet. Do you have any tips for that? (E.g. a QEMU VM with emulated USB devices, a Linux kernel driver which loads phony devices,...)?

mcuee · 2021-06-09T02:45:35Z

Yes from the very beginning of working with Travis Robinson on libusb-win32/libusbdotnet/libusbk back in 2009/2010 time, we were thinking about how to carry out tests, in the end he settled on using PIC MCU based USB examples as both of us were familiar with PIC USB stuff. Later Tarvis ported it to AVR32 as we need high speed USB examples as well and I got the support from Microchip/Atmel with some tools for Travis at that time. Pete Batard (original developer of libusb-1.0 Windows backend) actually ported the example to ARM as well.
https://github.com/mcuee/libusbk/tree/master/BmFW
https://code.google.com/archive/p/usb-travis/downloads (Arduino Due example from Pete)

I admit I knew very little about dotnet so I was not able to support it, but I did use the libusbdotnet benchmark example extensively over the years as a testing tool for my engagement in libusb-1.0 project as it is cross-platform. It is great that you took over libusbdotnet project from Travis.

I was also involved in pyusb and we had similar discussion as well. Right now Jonas has to disable the HW based tests as he does not have the necessary HW. Original pyusb developer adopted the same PIC MCU based approach but new developer does not have the HW. A virtual testing device mentioned by Emmanuel Blot (developer of pyftdi) is interesting.
pyusb/pyusb#235

mcuee · 2021-06-09T02:47:45Z

Using a QEMU VM to emulate the USB device may be a good idea if it is possible, I am not familiar with QEMU myself. Or maybe a Raspberry Pi running Linux USB Gadget driver.
https://github.com/torvalds/linux/blob/master/drivers/usb/gadget/function/f_loopback.c
https://www.isticktoit.net/?p=1383
https://www.kernel.org/doc/html/latest/usb/gadget-testing.html

Raspberry Pi Pico may be interesting as well.
https://github.com/raspberrypi/pico-examples/tree/master/usb

Under Windows there is this one (older version of WDK has similar stuff but was obsolete).
https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/developing-windows-drivers-for-emulated-usb-host-controllers-and-devices

OLD WDK USB Emulation sample (I tested it last time back in July 2011):

qmfrederik · 2021-06-09T08:12:41Z

Thanks, @mcuee . Both the Linux loopback driver and the QEMU approach look interesting, then. I'll explore them a bit further.

The QEMU/VirtualBox approach has the advantage that it should be trivial to set up a "standard" test environment which we can use on developer desktops and in CI systems, and we can run the test on different platforms (e.g. Windows or Linux as a guest).

The Linux USB gadget driver/USB loopback device look very interesting because they involve much less overhead. On the other hand, it may be more difficult to deploy to CI environments (we'll have to test).

qmfrederik · 2021-06-09T08:16:04Z

but I did use the libusbdotnet benchmark example extensively over the years as a testing tool for my engagement in libusb-1.0 project as it is cross-platform

As it stands, the benchmark example doesn't work on the master (v3) branch because async transfers are not implemented. .NET has a new model for async I/O and I would like to see if we can use that model. This will take some time.

I'll have a look at the v2 branch, and see if I can the v2 version to compile correctly with .NET core. It should enable you to use the benchmark tool on all platforms which .NET Core supports. I only want to make changes related to build tooling on the v2 branch, the master branch is for refactoring work.

mcuee · 2021-06-09T13:25:58Z

Please refer to #138.

Now you can use v2 branch under macOS if you need async examples. It also works under Windows and Linux.

mcuee · 2021-06-10T13:38:17Z

BTW, benchmarkcon can be very flexible and test any FW with loopback FW (interrupt transfer, bulk transfer and isochronous transfer).

Test done back in 2013.

With Cypress's cystream firmware and tested under Mac OS X
Lion 10.7.5 using a Mac Mini 2011 (lowest spec version but
upgradedto 8GB RAM).

Firmware: http://www.cypress.com/?app=forum&id=167&rID=48493
( http://www.cypress.com/?docID=35838 )

Board: An ADC demo board from ADI, just take out the
EEPROM of the Cypress EZ-USB FX2LP and download
the above firmware. The one from Cypress's original
download does not seem to work with a bare board.

Somehow this no longer works (CyStreamer FW) since I can not change to a different alternative interface. I will need to check again.

I have made some progress with Linux USB Gadget here. Still learning how to configure the usb gadget. The HW devices are really cheap (eg: Raspberry Pi Zero, Orange Pi Zero).

Thanks, @mcuee . Both the Linux loopback driver and the QEMU approach look interesting, then. I'll explore them a bit further.

The QEMU/VirtualBox approach has the advantage that it should be trivial to set up a "standard" test environment which we can use on developer desktops and in CI systems, and we can run the test on different platforms (e.g. Windows or Linux as a guest).

The Linux USB gadget driver/USB loopback device look very interesting because they involve much less overhead. On the other hand, it may be more difficult to deploy to CI environments (we'll have to test).

@qmfrederik
Maybe the dummy_hcd module will make it work. That is a software emulated device controller which works on normal Linux PC.
Please take a look at this discussion: vpelletier/python-functionfs#20
