Patch Set 2: Code-Review-1 (1 comment) File src/core/soft_uart.c: https://gerrit.osmocom.org/c/libosmocore/+/35044/comment/805a3c8e_44104bba PS2, Line 209: size_t osmo_soft_uart_tx(struct osmo_soft_uart *suart, how does this reject any buffer overflows? It is difficult to manage transmission with a buffer, IMHO. I would suggest to let the user of this API manage the data and simply call a function every time the transmitter wants to pull data out of the application-side buffer. This way it's up to the application to manage the size of the buffer, any kind of prioritization of different data, the overflow/overrun semantics, etc. Yes, that would mean one function call-back for each byte the transmitter pulls out of that buffer. If that really turns out to be a performance problem (probably with hundreds of parallel uarts, if we ever need that) we might want to pull multiple bytes at the same time. But in any case, I think we hve a fixed bit-rate consumer of data (the transmitter) and it should pull data. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/35044?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: Ibcd9643227e5616efd8bbd7a1430feda6fcef45c Gerrit-Change-Number: 35044 Gerrit-PatchSet: 2 Gerrit-Owner: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Comment-Date: Thu, 16 Nov 2023 15:16:40 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment
