[M] Change in osmo-pcu[master]: gprs_rlcmac_sched: fix condition for generating dummy blocks on idle

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-pcu/+/35096?usp=email ) Change subject: gprs_rlcmac_sched: fix condition for generating dummy blocks on idle ...................................................................... gprs_rlcmac_sched: fix condition for generating dummy blocks on idle When a PDCH is idle, then the gaps are filled with dummy blocks. OsmoPCU supports generating the dummy blocks locally, so that a continous stream of PDCH blocks is sent to L1. However, some BTS models (the OsmoTRX based models in particular) are able to generate the idle blocks locally. In this case the PCU should leave the genration of the dummy blocks to the BTS in order to save processing time and load on the PCUIF interface. In gprs_rlcmac_sched we already have a flag to skip idle frames in case we do not use the so called "direct phy access". A similar mechanism also exists in pcu_l1_if.cpp in function pcu_rx_rts_req_ptcch(). Unfortunately this check is not implemented correctly. The flag gets set when the ENABLE_DIRECT_PHY define constant is set. However, this does not say anything about whether the BTS model supports the generation of idle blocks or not. The define constant is intended to be used to disable direct phy related code in on platforms where no direct phy code is used or cannot be used. We must instead check the BTS model (bts->bts_model) in order to decide whether this particular BTS type requires the generation of dummy blocks or not.
