They seem to work for my programs, but I'm trying to use rtl_fm from the osmocom group at http://sdr.osmocom.org/trac/wiki/rtl-sdr. This machine boots into OpenBSD and an old Debian Linux and the program runs fine under Linux. If I can figure out how to make it work under OpenBSD I'd like to submit some ifdefs for it.
The program is for software defined radio using a $20 dongle plugged into a USB port that tunes 24 - 1700 MHz. It works under Linux and Windows, but under OpenBSD the demodulation doesn't keep up with the incoming data. The driver uses a callback routine when it has data, which does a sem_post that should enable a demodulation thread. It works after a fashion, but by the time it starts 5 or 6 more batches of data have come along and most of them get lost (in OpenBSD). I think maybe I need to change the priority on the thread if possible. I posted this question originally to StackOverflow: http://stackoverflow.com/questions/14392158/pthread-priority-scheduling-under-openbsd Have I run into one of the shortcomings of pthreads as implemented in 5.0? I'll probably upgrade to 5.3 when it comes out, but that involves hours of sitting in a car using a public WiFi connection which I don't plan to do until warmer weather.
