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 (d764240ef5da4d81e4cbf53e334e52af86c02728) \ N -- N -- N (9b980f4a78606652dff1523abb633bfc666ef8a0) 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=9b980f4a78606652dff1523abb633bfc666ef8a0 commit 9b980f4a78606652dff1523abb633bfc666ef8a0 Author: Thomas Tsou Date: Fri Nov 15 16:32:54 2013 -0500 Transceiver52M: Enable all warnings and resolve Mainly basic signed vs unsigned comparisons and intializer ordering.

Only channel zero can set this value. Other channels can attempt to set the TSC value, but will error if the TSC does not match the existing value. In either case, non-zero channels do not manipulate the gloabl TSC setting.

If we find a burst like this coming into the transceiver, then drop it immediately.

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.

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.

Currently device support is limited to UmTRX. Vectorize transceiver variables to allow multiple asynchronous threads on the upper layer with single downlink and uplink threads driving the UHD I/O interface synchronously.
