Change subject: bts: add IMMEDIATE ASSIGNMENT via PCH transmission ...................................................................... Patch Set 18: (4 comments) Commit Message: https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/c681e679_fca4667c PS18, Line 7: bts: add IMMEDIATE ASSIGNMENT via PCH transmission The commit message contains nothing about bumping the PCUIF version. Such changes should definitely be reflected in the commit log, IMO. File include/osmocom/pcu/pcuif_proto.h: https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/76c17bd0_245e4ec4 PS18, Line 43: PCU_IF_SAPI_PCH_DT Didn't we agree that in the new PCUIF version there will be only one way to send DL blocks over PCH and the message will always contain TLLI now. I remember Pau complaining that having several ways to do the same thing is a mess. My understanding is that there should be only `PCU_IF_SAPI_PCH` in the new version and it shall always contain a TLLI. Ah, now I see comments from Pau and your response about backwards compatibility. https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/8fddec62_fdec130c PS18, Line 273: is send typo: is sent File src/bts.cpp: https://gerrit.osmocom.org/c/osmo-pcu/+/31145/comment/4ec80c15_17cafdc2 PS17, Line 1134: pcu_l1if_tx_pch(bts, immediate_assignment, plen, ms_paging_group(tbf_ms(tbf))); > ... PCU will become incompatible with osmo-bts Yes, this is expected and desired when you bump the PCUIF version. > As far as I remember we decided to add a deprecation warning and upgrade > osmo-bts later. It was discussed *before* we came to a conclusion that bumping the PCUIF version is needed after all. The point was to prevent the user from running an old version of osmo-pcu, which does not support and ignores the new E1 configuration messages. > ... lets not get blocked by the BTS part and keep compatibility for now Ok, now I see the reason why you're keeping the old messages and backwards compatibility (nothing in the commit message explains that). But what would it take to get this implemented in osmo-bts? I can quickly help you with that, so we just bump the PCUIF version and be done with it. I think 1h would be enough for me to implement this on the BTS side. -- To view, visit https://gerrit.osmocom.org/c/osmo-pcu/+/31145 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-pcu Gerrit-Branch: master Gerrit-Change-Id: I2a78651593323e8b9627c39918d949a33497b70f Gerrit-Change-Number: 31145 Gerrit-PatchSet: 18 Gerrit-Owner: dexter <[email protected]> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <[email protected]> Gerrit-Reviewer: laforge <[email protected]> Gerrit-Reviewer: pespin <[email protected]> Gerrit-CC: neels <[email protected]> Gerrit-Attention: neels <[email protected]> Gerrit-Attention: pespin <[email protected]> Gerrit-Attention: dexter <[email protected]> Gerrit-Comment-Date: Tue, 28 Feb 2023 19:10:34 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <[email protected]> Comment-In-Reply-To: dexter <[email protected]> Gerrit-MessageType: comment
