It was generated because a ref change was pushed to the repository containing the project "GNURadio hardware abstraction block". The branch, blade-async has been updated via e2411632119c9122716a726f682d3f2587c5f632 (commit) from bf684698e8428902ea601795796a5756df4673c0 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/gr-osmosdr/commit/?id=e2411632119c9122716a726f682d3f2587c5f632 commit e2411632119c9122716a726f682d3f2587c5f632 Author: Jon Szymaniak Date: Sat Sep 21 16:53:16 2013 -0400 bladeRF: Refactored buffering scheme in sink Removed the use of an intermediate sample FIFO in the sink implementation. Note the the FIFO has not been moved out of bladerf_common --> bladerf_source_c in this commit. work() now handles converting samples from complex to SC16_Q12, and filling "transmit-ready" buffers. The callbacks are now only responsible for marking the provided buffer free, and returning the next buffer. It appears that a small deadlock issues remains in this changest, which can be induced by: 1: Using a small sample rate (160Khz) 2: Switching back and forth between sinusoid <-> GSM burst In this case, it appears that work() is blocked waiting for a buffer to become free. More investigation here is required... ----------------------------------------------------------------------- Summary of changes: lib/bladerf/bladerf_sink_c.cc | 206 ++++++++++++++++++++++++++++-------------- lib/bladerf/bladerf_sink_c.h | 25 ++++- 2 files changed, 160 insertions(+), 71 deletions(-) hooks/post-receive -- GNURadio hardware abstraction block
