Volume II - Status Update and call for requests

[morpheus]

At the usual page - http://newosxbook.com/2ndUpdate.html - also previews cover

If you have any particular requests - it's not too late to submit. ARM64 will naturally be covered now that it's open source, as will EFI, iBoot (with detailed explanation but no source), and even SEP OS. Also aiming to provide a primer on hardware, and show detailed kernel memory management internals and IOKit in unprecedented detail (which were two notable omissions from the 1st ed due to page count restrictions).

And - there will be a hardcover, color edition. But not before early 2019.

Thanks for the update. It would be great to have some details of xcpm and AWDL.

Thanks! I would love some details on the inner workings and boot architecture of the iBridge (T1 and T2).

I would like details on how the iPhone disables JTAG if the device is production

From http://newosxbook.com/articles/12-10.14.html:

Turnstiles are from Solaris not BSD.

[morpheus]

Nice to know there are people who still remember the world's best operating system! And thanks for the note. It just seems that AAPL took the BSD turnstile code (https://github.com/freebsd/freebsd/blob ... urnstile.h) and adopted it. But your comment just made it into Volume II - I was crediting BSD there, too. I'm seeing now the original implementation in http://www.hpdc.syr.edu/~chapin/cis657/ ... ource.html and yeah - Solaris. Damn, that was a great Operating System
