[XL] Change in osmo-trx[master]: libosmo-trx/ep: add TRX endpoint module
by fixeria 04 Aug '26

04 Aug '26

Attention is currently required from: fixeria, pespin. Hello Jenkins Builder, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-trx/+/43111?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Code-Review+1 by pespin, Verified-1 by Jenkins Builder Change subject: libosmo-trx/ep: add TRX endpoint module ...................................................................... libosmo-trx/ep: add TRX endpoint module Add the osmo_trx_ep module, encapsulating the clock/ctrl/data UDP socket management of the TRX protocol on top of osmo_io. One endpoint serves an (optional) clock socket plus N channels, each channel being a ctrl + data socket pair. The module is role-neutral: struct osmo_trx_ep_cfg carries a mode (OSMO_TRX_EP_MODE_{L1,TRX}) selecting which side of the protocol the endpoint implements. The mode is needed to parse datagrams received on the data sockets, as the wire format alone does not identify the direction (BURST.ind vs BURST.req). All local and remote ports are derived from a single base port (default: 5700). To avoid indirect calls on the hot path, the decoded Rx handlers (osmo_trx_ep_rx_*) are plain function prototypes bound at link-time, not function pointers. The library provides weak default stubs to stay link-complete (-no-undefined), so applications only implement the handlers for the directions they consume, overriding the stubs. The Tx path implements TRXDv2 PDU batching for burst requests: osmo_trx_ep_send_burst_req() accumulates PDUs until it is called with br == NULL (the batching breaker), like in osmo-bts-trx. osmo-trx itself will not adopt this module: its per-channel/thread socket ownership model (dedicated blocking-read threads per socket) is incompatible with osmo_io's single-select-loop dispatch. It is meant for osmo-bts, osmocom-bb/trxcon, and the upcoming C rewrite of fake_trx.

[M] Change in osmo-trx[master]: Transceiver52M: implement TRXDv2 support

Attention is currently required from: fixeria, pespin. Hello Jenkins Builder, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-trx/+/43116?usp=email to look at the new patch set (#5). The following approvals got outdated and were removed: Code-Review+1 by pespin, Verified-1 by Jenkins Builder Change subject: Transceiver52M: implement TRXDv2 support ...................................................................... Transceiver52M: implement TRXDv2 support TRXDv2 was proposed and implemented in osmo-bts a while ago, but osmo-trx was still stuck at TRXDv1. This patch implements TRXDv2 and UL/DL burst batching using libosmo-trx API. DL: driveTxPriorityQueue() now loops over osmo_trxd_burst_req_parse() to handle datagrams potentially containing multiple batched BURST.req, dispatching each via the new handleBurstReq(). UL: accumulate BURST.ind PDUs for the same FN into one msgb per channel and flush as a single datagram once the next frame's PDU arrives or the channel stops; TRXDv0/v1 channels keep sending one PDU per datagram via sendBurstInd(). Batching is unconditional for now; making it configurable is left as a follow-up.
