New OSKit release, 0.97
As before, go to http://www.cs.utah.edu/projects/flux/oskit/
and everything hangs off there including mailing list archives.
The significant changes in 0.97 are:
Many thread library fixes and improvements. CPU inheritance
scheduling is much more stable, as is the generic threads code.
Restructuring of the minimal C library and FreeBSD C libraries. The
syscall to COM layer was split out into a separate library (see the
'posix' directory). Both C libraries now use the posix library for the
COM layer calls. [We forgot to put this in the 'roadmap' in the doc
intro but that will happen soon.]
Patch1 to 0.96:
Fixes to the FreeBSD ISA device drivers. Now operational, and can be
used to provide a proper console TTY device that does cooked input.
See the example program console_tty.c in examples/x86/extended,
which demonstrates how to initialize a console TTY device and have
the FreeBSD C library make use of it.
Changes to how boot options are handled; OSKit programs no longer
see booting-options, such as "-h" or "-d", in argv. These are now
stored in the oskit_bootargv array. This is to make porting Unix
programs to the OSKit easier since they do not need to have special
OSKit code to tweak argv. Syntax is documented at the end of the
Intro chapter.
We provide a mini-Java-shell for the Kaffe/OSKit environment. All
the OSKit changes have been merged into Transvirtual's tree (but
shortly after they did a major change in build tools so we provide a
separate Kaffe tar file for the nonce).
The above improvements were mainly due to the good work of Leigh Stoller;
Bart Robinson did the booting/cmdline work and Godmar Back does a lot in all
Kaffe-related work.
Fixes for all the bugs/fixes you sent in (thanks!) and others, including:
-Fixed remote GDB code so function calls from GDB work correctly.
-Linux ext2fs fixes
-lmm assert fix
-fix sleep record leak in linux/dev
-mklinuximage upgraded to match other mk* scripts
-Bad linuxboot.bin.good replaced with good uuencoded linuxboot.bin.uue.
Small stuff, including:
-Changes to support Kaffe.
-Add a #define for _OSKIT_VERSION in oskit/version.h.
-Some new files in preparation for importing secure filesystem and
networking components.
-Document arg syntax for mk*image scripts, in their comments.
Keep sending in those bugs and patches, let us know what you're using
it for, and let us know what new stuff you'd like to see or are
writing yourself.
