[Xenomai-help] Advice needed: Xenomai / USB access from kernel task

One of our trainees has written a LKM that accesses the standard Linux kernel's usb_core facilities from a Xenomai real-time thread running in kernel space. I am doing some follow up on his work and run into problems. I would appreciate some help/advise. 1) The main question to start with: is it

[Xenomai-help] Advice on running Xenosim/MVM

[Xenomai-help] Non RT PCI device driver vs interrupts (go with rtdm...)

Finally, I got the precision I expected. The problem was on the way the results were reported. However, more the frequency of the pulse generator is raised, less the results are good. I think it is time to go with rtdm... Thanks Hubert ___ Xenoma

[Xenomai-help] gpioirqbench: measuring external interrupt latencies

Hello, I'm proud to announce "gpioirqbench", a benchmark tool to measure external interrupt latencies. It is derived from Jan's irqbench [1] for the PC. Instead of using the serial or parallel port, it uses GPIO pins on embedded systems. It measures the time between the generation of an interrupt
