Patch Set 2: -Code-Review (1 comment) File src/gprs_rlcmac_sched.cpp: https://gerrit.osmocom.org/c/osmo-pcu/+/35151/comment/37d05e16_c8ed98a1 PS1, Line 486: * way we help BTS energy saving (on TRX!=C0) by sending nothing

Oh, I overlooked the `skip_idle && trx != 0` part in the old code (left side). […] @vyanitskiy@sysmocom.de bear in mind the "skip_idle && trx != 0" was only applied inside the #ifdef DIRECT_PHY, so it was only really applied for sysmobts,lc15,oc2g. And that was done in order to make it send stuff on C0 because those osmo-bts lowerlayers are not filling the block otherwise. For trx!=0 it's fine sending empty block to those osmo-bts flavours, because it's fine if they end up transmitting nothing on those TRX.

I realize now though, that when proposing the cleanup in this patch, I assumed those were 1 TRX only, but lc15 has several of them right? With the current version of the patch, it will still transmit dummy blocks on trx!=0, and that's not what we want. We want to transmit nothing on trx!=0. So the could should be left as it was and this patch dropped? Maybe we can reuse this patch to rename bts->gen_idle_blocks to be "gen_idle_block_C0". -- To view, visit https://gerrit.osmocom.org/c/osmo-pcu/+/35151?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-pcu Gerrit-Branch: master Gerrit-Change-Id: Iadb62748b18605bf158169b317f880352bc0a5a6 Gerrit-Change-Number: 35151 Gerrit-PatchSet: 2 Gerrit-Owner: dexter <pmaier@sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy@sysmocom.de> Gerrit-Reviewer: laforge <laforge@osmocom.org> Gerrit-Reviewer: pespin <pespin@sysmocom.de> Gerrit-Attention: fixeria <vyanitskiy@sysmocom.de> Gerrit-Attention: dexter <pmaier@sysmocom.de> Gerrit-Comment-Date: Wed, 29 Nov 2023 12:32:47 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Comment-In-Reply-To: fixeria <vyanitskiy@sysmocom.de> Comment-In-Reply-To: pespin <pespin@sysmocom.de> Comment-In-Reply-To: dexter <pmaier@sysmocom.de> Gerrit-MessageType: comment
