ELKS release 0.1.4



I am pleased to announce that I have released version 0.1.4 of the Embeddable Linux Kernel Subset! This is primarily a bug fix release, but other factors are at play that compelled a new version release, particularly the fact that my overzealous release of "ELKS 0.1.3" in May 2006 turned out to be a significant mistake, since the code did not compile AND even if patched to compile, it didn't carry the correct version number throughout. I fear that releasing that broken tarball may have only driven more nails into the ELKS coffin, but this release corrects the major problems in the 0.1.3 compilation process and also removes dead configuration options that likely confused and annoyed many newcomers. I would especially like to thank Juan Perez-Sanchez for contributing critical compilation and IRQ patches, as well as indirectly restarting ELKS development through those submissions.

The CVS commits (dated up until 2006) have been imported into a shiny new Git repository, and the elks, elkscmd, and elksnet repositories have been merged into one Git repository and one single release tarball. ELKS 0.1.4 contains many useful fixes. Notable to newcomers is a significant cleanup of the code base, with removal of a number of useless configuration options, "vaporware" features, and unneeded code. The full commit log has been included below. We need your help! If you're reading this message, please feel free to compile the kernel, throw it on a floppy, boot it up (even if only in an emulator), and test it out. If you can code, submit patches to the mailing list or to me directly for consideration and inclusion. If you can't code, feel free to clean up the documentation, as it could use some reorganization.

In closing, I would like to dedicate this release of ELKS to Riley Williams, an ELKS developer who died tragically many years ago, and who was responsible for almost single-handedly pushing ELKS progress for many years before his death. As a significant contributor (and a really great fellow) who is unfortunately permanently "stored in the cloud," I feel that he deserves this honorary mention in his memory.

Thanks to everyone that made this release possible!

    Removed CONFIG_NOT_YET from the kernel entirely. As of now, the
    only non-existent code should be CONFIG_MODULES, which was also
    slightly tweaked in this commit for clarity. To remove the option
    CONFIG_MODULES, tri-state menu options would also need to be taken
    out, so for now, we are leaving it in place.

    Removed expanded memory (EMS) configure options and dummy code.
    EMS support is not feasible to add, and EMS memory is extremely
    difficult to find in 2012, so there is no point in keeping it.

    Removed elksfs filesystem; it is a clone of the Minix filesystem,
    and other than changing references in the code to contain the new
    name, elksfs contains no new or useful code at all, thereby only
    bloating the code base without a purpose. Furthermore, no tools
    seem to exist to create an elksfs filesystem on disk, and no
    reference exists to outline the structure of elksfs. Since it is
    pure bloat with no value, it must be removed.

    If "make Image" is run, it seems that arch/i86/Image is never
    deleted on a "make distclean" when it should be. This patch fixes
    the (trivial) problem.

    In arch/i86/drivers/char/meta.c, a struct declaration issued a
    function call with a variable whose declaration was placed after
    the struct declaration, causing a compile error. I have moved the
    variable's declaration to be performed first, fixing the compile
    error.

    In elks/fs/romfs/inode.c, the function romfs_copyfrom() accepts
    Void *dest, but an invalid lvalue error was generated by this:

      ((char *)dest) += maxsize;

    By asking for char *dest instead, the function compiles properly.
    Since romfs is "in development," I cannot test the code, but it
    at least compiles now.
