04:22:19 <julius_01> Hey, I'm new to illumos. Which components of the kernel still contain components from the Sun era? 
06:12:46 <MelMalik> Most of them?
12:25:59 <toasterson> There was never a need for rewrite, but all of them are Open Source. Closed components have their dedicated repo and can be used if whished but no need to.
13:20:07 <julius_01> I understand. And if for example a developer develops a device driver for use with illumos then the CDDL is used? 
13:57:33 <toasterson> No, the repo is under CDDL but it's a copy left license same as the MPL v2 and out of tree drivers are possible
14:29:38 <julius_01> Thanks. I cloned the repo of illumos and it's my first time reading the source code of an OS
14:30:23 <toasterson> It's a good code. Has some nice frameworks to write drivers in
14:31:24 <julius_01> I occassionally programmed in C, but what I've seen in the source looks very different from I have done 
14:31:37 <julius_01> *what I have programmed
14:41:46 <julius_01> I'm interested in writing drivers, but that's still a long way. And right now I am not sure how to start such a project. I just imagine that a person capable of writing device drivers gets a new computer, checks its components with a device driver utility (for example on OI) and then sees that a specific device (e.g. a mouse) is not yet supported. And if there is enough documentation about that device and the developer is experienced, h
14:41:46 <julius_01> e would start such a project?   
14:54:30 <toasterson> https://illumos.org/books/wdd/bookinfo.html#bookinfo
14:54:50 <toasterson> This has all the getting started guides
14:59:42 <rmustacc> julius_01: My suggestion is to get used to the build, development, and test cycle with some small change that's not a brand new driver first.
15:00:32 <julius_01> perfect, thanks
15:00:50 <rmustacc> WDD does have a bit of background, but for a new driver the first questions are going to be things related to the device interface. What protocol does it speak, how do I communicate with it, is there documentation for it, etc.
15:06:17 <julius_01> ok, I'm going to study the details. Luckily I have an old serial mouse and a floppy disk drive; I know that there are drivers out there, but writing my own drivers for those two devices is on my to-do list and then trying it on an illumos-based os would be perfect
15:32:37 <rmustacc> If you have questions, don't hesitate to reach out in the channel.
15:51:02 <julius_01> Thanks, I'll ask if something is not clear
