Last week I've spotted volume 1 of a multivolume series dealing with the innards
and design issues of operating systems, specifically a BSD port (386BSD) to the
Intel architecture. I perused it a little and found its attack of the issue very similar
to 'literate programming' -- a detailed discussion of actual source code and the
trade-offs involved in choosing presented solution.
I'm currently experimenting with FreeBSD at home (switched from LinuX just to try
a 'real' UNIX and, as application programmer, found still no incentive to switch back
-- praise to contributors & core team ), therefore these questions:
How relevant is a detailed discussion of 386BSD for FreeBSD ? Are the differences
minor ('mov ax, offset foo' instead of 'lea ax, foo' in locore.s) or significant
(what is locore.s ?). Are the differences confined to the machine-dependent parts
or have the kernel architectures (VM system, file-systems, ...) significantly departed ?
The bibliographic data is:
Operating System Source Code Secrets
Vol I: The Basic Kernel
Peer-to-Peer Communications, Inc.,
San Jose, California
ISBN 1-57398-026-9
The preface mentions other volumes in print or in progress (I hope this doesn't
become a venture like Knuth's 'unfinished' :-)
Vol II: The Virtual Memory Subsystem (ISBN 1-57398-027-7)
Vol III: The Filesystem
Vol IV: POSIX and Windows Sockets
Vol V: The Internet Protocol Suite
Vol VI: The UFS Filesystem
The (numerous) footnotes refer to just another book, '386BSD From the Inside-Out'
and to the article series in Dr. Dobbs Journal. A WWW site is also mentioned
(http://www.386bsd.org) but this leads to a GO game site (another practical
Jolitz joke ?)
