gitosis at osmocom.org gitosis at osmocom.orgThis is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "Osmocom BTS-side code (Abis, scheduling, ...)". The branch, neels/dyn_no_pcu has been updated discards 42edba5fe67ac96d4dde6ebb5f5d84fea9124f4f (commit) discards 370a91c4eac99948376c2175ef9e352c70be2b53 (commit) via 7ea38df5378309a5eb831125dbebbec34aab107e (commit) via bf6bae2b2363a182bb1b95574c2922bf4257c4d9 (commit) via 8a148613b4c93f5a25dd2a2d9929de75882adbc5 (commit) via 4dfc3da96bbad9e6a8641233c87a05a46af7d906 (commit) via 9faaf4ecf01322189808901398e06d7e4f14560d (commit) via 3b2e5de3aea8652969e7bbd1e3c04206dce51330 (commit) via 988f634c97d070840f4ffc952f6bac32d967859b (commit) via e77bcaecb6e45b55b8e31fea7cf10c2652431c1c (commit) This update added new revisions after undoing existing revisions. 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 (42edba5fe67ac96d4dde6ebb5f5d84fea9124f4f) \ N -- N -- N (7ea38df5378309a5eb831125dbebbec34aab107e) 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-bts/commit/?id=7ea38df5378309a5eb831125dbebbec34aab107e commit 7ea38df5378309a5eb831125dbebbec34aab107e Author: Neels Hofmeyr <nhofmeyr at sysmocom.de> Date: Mon Aug 22 23:07:09 2016 +0200 dyn TS: if PCU is not connected, allow operation as TCH Before this patch, Osmocom style TCH/F_TCH/H_PDCH dyn TS were paralyzed if no PCU was running. The state of the dyn TS would lock up in the PDCH activation phase since the PCU never completed the process. Make more robust, i.e. don't concern the BSC with PDCH activation failures. This matches the way plain PDCH TS work: besides declaring the TS as PDCH, the BSC is not involved and is not told about errors. During PDCH deactivation, still wait for the PCU to tear down the PDTCH SAPIs, but in case no PCU is connected, send a rel ack right away. Thus, the BSC will happily switch Osmocom style dynamic timeslots to and from PDCH mode, using the dyn TS as voice channels as needed, and not caring about possible PDCH failures. GPRS starts working right away as soon as a PCU connects, regardless of dyn TS having been used for voice any number of times, and without another switchover needed. In detail: In rsl_rx_chan_activ(), upon receiving a PDCH activation, send an RSL chan act ack right away, unconditionally (with an explaining comment). Do not concern the Abis link with PDCH activation failures. Since we're acking right away now, drop the chan act ack that would follow after the PCU activation: as before dyn TS, only send acks and nacks for rel_act_kind == LCHAN_REL_ACT_RSL (PDCH runs as LCHAN_REL_ACT_PCU). In dyn_ts_pdch_release, indicate that the PCU is not connected by means of returning 1. In rsl_rx_rf_chan_rel(), use this indicator to send a rel ack right away if the PCU is not connected.
