Thank you for your mail and thanks for reaching out! I was one of the ones responding on IRC, unfortunately you caught me at a bad time here, hence my suggestion to send an e-mail. I know the FreeBSD graphcis effort have been somewhat dormant (yeah, that's an understatement), but I'm working on getting it going again with a group of people. It's still in the early stages but hopefully something will come out of it. We had such a team about 4 or 5 years back, but people, including myself, got different priorities (you know, life happens). Currently, we have a working area and development repos on gitub, which you can find here https://github.com/FreeBSDDesktop/, amongst other things there's a fork of the FreeBSD ports repo there where most ports development happens. There's no problem getting you access to that one, and we can also add forks of upstream mesa and drm repos and so on. We also have a gitter chat that we're trying out. It can be found here: https://gitter.im/FreeBSDDesktop/Lobby, you're welcome to join there as well. It's connected to github. The IRC channel #freebsd-xorg is unfortunately somewhat dormant, because not everyone hangs out there, but I'm available there as well. As I said, we're still early in the process, so all details aren't 100% set yet, but this is what we have going for now. Now, to your questions. As far as I know, there's no automatic loading of the graphics modules, apart from the really old stuff. If memory serves me correctly. The current way of doing it is to load the module before starting X, usually as part of the boot process. There might be a hack in xf86-video-intel to load some modules, but not the latest kms graphics modules. Creating /dev nodes is handled automatically by devfs and devd. I don't know how it's done in detail, but it's automatic as far as at least I'm concerned. As for sysfs, mmacy gave a good responce on IRC. For patches and contributing, as I said, we're trying to set up shop on github (and from there merge into FreeBSD SVN repos). The kernel bits (what's called drm-next sometimes) are already there, and I've started working on a ports repo there as well. That's probably the best place to start. We don't have a CI setup currently, I use the package building system poudriere locally on my desktop. I can help you get started with both poudriere and the FreeBSD ports system, and I can also help with adding patches to the ports and build packages for testing. I hope to be able to add more automatic building and some sort of CI solution in the future, but this is where we're at today. We already have some local patches, they should be upstreamed, but I haven't had time to work through them, and since I don't know exactly how they work, it will take some time to get them upstream. Can I contact you directly to get them upstreamed once they're ready? Once again, thank you very much for reaching out, and thank you for reading to the end!
