Max gerrit-no-reply at lists.osmocom.orgHello Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/3067 to look at the new patch set (#5). trx: avoid deactivating lchan on LCHAN_REL_ACT_REACT * do not deactivate lchan when called with LCHAN_REL_ACT_REACT * add fixme comment It's unclear yet if any special steps are required for osmo-bts-trx so let's just make it compatible with setups [1] using BS_AG_BLKS_RES != 1 for now. Background: CCCH is activated very early by OsmoBTS - before we receive SI3, see 4a8582846281322e8d7dfc577b18767cf35c24d1. To accommodate for that we deactivate CCCH in common/rsl.c, which triggers BTS-model specific callback sapi_deactivate_cb() which updates parameters and activates it again. In case of osmo-bts-trx there (seems to be) no need in special interaction with hw to activate channel (no lchan_activate()) hence we can just skip entire deactivate/setup/activate again routine. [1] "channel-descrption bs-ag-blks-res N" in OpenBSC config file.
