From mboxrd@z Thu Jan 1 00:00:00 1970 From: clemc at ccc.com (Clem Cole) Date: Thu, 10 Jan 2019 10:23:47 -0500 Subject: [COFF] Most folks here started their OS learning with Unix In-Reply-To: References: Message-ID: The architects of MIT's 6.828 course "Operating Systems Engineering") were unsatisfied with the current stable of systems for teaching, so they did a reimplementation of 6th Edition in modern ANSI C (with a couple of GNU extensions for things like assigning names to registers) targeting a multiprocessor x86. As I look it, it is a clean interesting, and accessible piece of work. As the person that mentioned it to be said: "a modern take on a classic" - the course if being offered this fall at the URL: 6.828 / Fall 2014 The latest xv6 source is available via git clone git://pdos.csail.mit.edu/xv6/xv6.git Tools are can be found at: 6.828 / Fall 2014 Using the MIT course or the Lion's text will teach how the kernel works and how a user program interacts with it. IMO: Lion's commentary is super and 100% of the source is there to read and ponder. Please remember that generations of the best kernel hackers started with this document (although some of us predate it - but when I saw it I made a copy). And as I said, I just looked at the MIT documents and they are awesome too; but I have just opened them up and have not yet gotten a chance to try the exercises. What is even cooler is if you want to try xv6 - it will just run on your system using QEMU (which the MIT folks point too - they even made some mods to QEMU to help with their project). ᐧ On Thu, Jan 10, 2019 at 10:00 AM David wrote: > Myself it was v6 (most likely the typesetter version). > > What I’d like to see discussed is how people today learn to write, > enhance, design, and otherwise get involved with an OS. > > When I was teaching at UCSD my class on Unix Internals used writing a > device driver as the class project and covered an overview of the Unix OS > using the Bach book.
