an fpos_t, use ftell which returns an int. Without the patch,
Bochs gets an fpos_t and assumes it is an integer type, but
on some systems (like linux with newer glibc libraries) this
assumption is wrong. Malte Cornils <malte@cornils.net> first
reported this bug, and he warned me that ftell may not be portable
to some platforms which treat binary and ascii streams differently.
I haven't found any alternative yet.
gui/control.cc and the simulator. Now all communication between
the control panel and the rest of bochs goes through an object
called bx_simulator_interface_c.
[ #430472 ] DOS HIMEM "A20 line" error
All I've done is moved the call to print_bios_banner later in the
boot process, and the A20 problem goes away. I wanted it early so
that it would get printed before any panic or halt could happen.
Oh well.
- remove --enable-external-cpu-memory
- Neither of these options were compiling anymore, and Kevin suggested:

<tom@debet.shh.fi>, and I took his suggestion of moving the MP structures
to the end of the file.
I don't have to list them, and also apparantly fixes a mysterious problem
which occurred when Anders Nielsen was trying to build the RPM for
PPC: his rpm appears to gzip the man pages automatically, and then
complains that /usr/man/man1/bochs.1 is not found!
- 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
BX_CPU_C bx_cpu;
BX_MEM_C bx_mem;
and when more than one processor, use
BX_CPU_C *bx_cpu_array[BX_SMP_PROCESSORS];
BX_MEM_C *bx_mem_array[BX_ADDRESS_SPACES];
The changeover is controlled by BX_SMP_PROCESSORS, but there are only
a few code changes since nearly all code uses the BX_CPU(n) and BX_MEM(n)
macros.
- This turns out to make a 10% speed difference! With this revision,
the CVS version now gets 95% of the performance of the 3/25/2000
snapshot, which I've been using as my baseline.
is the first attempt to regain the performance of pre-SMP bochs
(1.1.2). When simulating only one processor, stay in cpu_loop forever
as pre-SMP versions did. The overhead of returning from cpu_loop over
and over was slowing us down.
