which were generated with gcc -MM to the end of each Makefile.in
so that make understands which files depend on which. Basically,
everything depends on bochs.h, which depends on everything, which
is not ideal.
to run the conf script in order to even have a Makefile. Instead, I just
added some instructions that tell you to run the .conf.win32-vcpp script
yourself and then do "make win32_snap" to unzip the workspace files and
zip up the whole source package.
--with-amigaos is allowed and sets up the makefiles correctly. It
defines a symbol called BX_WITH_AMIGAOS, which should be used in
#if..#endif constructs that are specific to amigaos.
- if --enable-cdrom is used with --with-amigaos, the cdrom_amigaos.o
object file will be added to CDROM_OBJS in the iodev makefile.
- start using autoconf/configure's standard of prefix, exec_prefix, bindir,
mandir to control where make install puts things
- added script install-x11-fonts
- make install no longer tries to install DLXlinux (since not everyone will
want it). Now you must do make install_dlx if you want it.
- renamed erase_install to uninstall
- in RPM spec file:
- run .conf.linux instead of .conf.linux-x86. This is just a name change.
- build directory hierarchy in the buildroot
- patch up broken symbolic links in buildroot (ugly)
- run font install script in %post
- clean up dlxlinux directory in %preun to avoid warning about not
removing /usr/local/bochs/dlxlinux/bochsout.txt
- remove /usr/local/bochs if nothing left in it
in BRANCH-smp-bochs revisions.
- The general task was to make multiple CPU's which communicate
through their APICs. So instead of BX_CPU and BX_MEM, we now have
BX_CPU(x) and BX_MEM(y). For an SMP simulation you have several
processors in a shared memory space, so there might be processors
BX_CPU(0..3) but only one memory space BX_MEM(0). For cosimulation,
you could have BX_CPU(0) with BX_MEM(0), then BX_CPU(1) with
BX_MEM(1). WARNING: Cosimulation is almost certainly broken by the
SMP changes.
- to simulate multiple CPUs, you have to give each CPU time to execute
in turn. This is currently implemented using debugger guards. The
cpu loop steps one CPU for a few instructions, then steps the
next CPU for a few instructions, etc.
- there is some limited support in the debugger for two CPUs, for
example printing information from each CPU when single stepping.
- change Makefile.in to "cvs-snapshot" information rather than printing
the release number, since in fact it's not the same as the release anymore
- use #defines to give the actions names (ACT_IGNORE, ACT_REPORT, ACT_FATAL)
- register all logfunctions as they call setio, and keep a list so that
we can change their settings more easily. I admit I used a static-sized
array to store them. Sorry.
- instead of printing a prefix [GEN ] for generic messages, just leave the
prefix blank [ ]. Otherwise you start wondering what does gen stand
for.
- avoid reentry into fatal, since fatal can call BX_INFO and friends.
This avoids a potential infinite recursion.
- now that files other than .bochsrc can be the rc file, print the
actual name of the file in error messages.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.
In general this provides a generic interface for logging.
logfunctions:: is a class that is inherited by some classes, and also
. allocated as a standalone global called 'genlog'. All logging uses
. one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
. class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
. respectively.
.
. An example usage:
. BX_INFO(("Hello, World!\n"));
iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance. It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf(). At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.
More cleanup is coming, but this works for now. If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.
