in my quest to make FreeBSD fully operational in my laptop, I would like to know whether anyone is working on porting the OpenBSD rtsx to FreeBSD.
I have asked to Robert (https://lists.freebsd.org/pipermail/freebsd-questions/2015-February/264014.html) about its working on the module but he has not yet got the chance to start it.
If not, I'd try to develop it personally, but I have to be sure the better workflow: is it better to integrate it with sdhci/mmc modules or start it brand new?
the request to port this driver came up again on freebsd-hackers again. Warner Losh gave some insight about what needs to be done to port rtsx.
