That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (946db998291c0da1b8d5428965b222a75738fcb4) \ N -- N -- N (a87441c114a4425166aca776671f7d53bad95dee) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. 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/osmo-trx/commit/?id=a87441c114a4425166aca776671f7d53bad95dee commit a87441c114a4425166aca776671f7d53bad95dee Author: Thomas Tsou Date: Fri Nov 15 23:00:28 2013 -0500 Transceiver52M: UHD: Check running status before stopping stream On startup errors we get a segfault if we stop and shutdown.

This allows two antennas two shared antennas to be used for each ARFCN handling channel in the receiver. This configuration may improvde performance in multi-path fading environments, however, noise andpotential interference levels are increased due to the higher bandwidth used. The receive path is oversampled by a factor of four for a rate of 1.083333 Msps. If the receive paths are tuned within a maximum channel spacing (currently set at 600 kHz), then both ARFCN frequencies are processed by each channel of the receiver. Otherwise, the frequency shifted diversity path is disabled and standard non-diversity operation takes place. Diversity processing is handled by selecting the path with the higheset energy level and discarding the burst on the second path. Selection occurs on a burst-by-burst basis.

This is unnecessary because the latter is a derived class making the first allocation unnecessary. Modify the radioVector constructor to allow direct use in the case above.

Avoid both cases by dynamically allocating with preloaded head room. The latter provides enough memory before the first sample in the burst to cover the length of the filter taps.

This adds additional stability primarily on ARM platforms.

In this case, use ARM assembly directly as the NEON intrinsics do not generate preferential code output. Currently support NEON vectorized convolution and floating point integer conversions.
