[PATCH] rtl-sdr/lib: take 2 manually releasing async buffers
by Karl Semich 21 Sep '18

21 Sep '18

New rtl-sdr manual buffer resubmission patch after discussion on IRC. This implementation uses the existing rtlsdr_read_async API and is more compartmentalized.

[PATCH} gr-osmosdr/rtl: overflow fixes
by Karl Semich 19 Sep '18

19 Sep '18

RTLSDR driver is amended to handle overflows in a robust way. Previous code appeared to have many issues: overflows were happening more than needed and could result in data corruption. Handling is changed to stop the stream when buffers are exhausted, and restart it when they have drained. I apologize that my patches are sent as attachments; I only have access to webmail at this time.

Hi, I've modified gr-osmosdr such that all devices respond to message commands ala USRP. I feel this is a really valuable addition, and I am happy to continue to work with it to meet any needs or desires. Please let me know that this e-mail was received. Thanks so much, Karl

[PATCH] Add API for releasing zero-copy USB buffers
by Karl Semich 19 Sep '18

19 Sep '18

Hi, I was trying to take advantage of the async zero-copy buffer feature in librtlsdr, but I found that the automatic resubmission of them made it hard to make use of them safely. This patch adds a couple function to manage buffers in a more advanced manner, so that latency and reuse can be tracked precisely. I also added some documentation. I can occasionally make a lot of mistakes, so if anybody has time to take a brief glance through, it would be really great. Karl
