Dear Wander and Greg, [resend on base of email-bot of Greg Kroah-Hartman's inbox] I have noticed that you have sent enhancements to the TTY layer. I have worked on architecture of automotive LIN-bus support for Linux UARTs. The SocketCAN API was idea of Oliver Hartkopp and we have designed internals to implement actual protocol. Rostislav Lisovy was main author at our university in 2011. The code has been used and is used by more people and I have helped its integration to local Volkswagen subsidiary projects. I have helped to maintain it for years even that I have actually no use for it or contract. But is seems usable... I am not sure if it can reach quality standards for mainline but I have tried to consolidate many forks and copies from our original GIT server which can be found on GitHub and united project under https://github.com/lin-bus Kernel part - slLIN TTY discipline - can be found there https://github.com/lin-bus/linux-lin/tree/master/sllin Documentation https://github.com/lin-bus/linux-lin/wiki/ The main obstacle to have version which can be used with different UARTs seamlessly is missing internal low level kernel API which would allow to control Rx trig level. I have not checked your changes yet but I would be happy if some API is available for this control. Please see issue https://github.com/lin-bus/linux-lin/issues/13 Please suggest where to discuss the proposal/solutions or if you plan to implement something like that. I would be happy to work on that myself or with my students but I personally do not get to that probably earlier than in summer. I have to finish project for European Space Agency at PiKRON company. We have quite lot of work to switch our Computer Architectures classes and corresponding QtMips/QtRvSim simulator to RISC-V etc... Mainlining CTU CAN FD driver has higher priority than LIN for me as well. So my actual motivation is to document the need and get some feedback if some such solution is on the horizon and what should API look like if I get to it ourselves etc..
