to describe the format of the log prefix. This option can be any string
with special tokens being replaced at run time :
# %t : 11 decimal digits timer tick
# %i : 8 hexadecimal digits of cpu0 current eip
# %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
# %d : 5 characters string of the device, between brackets
the default is "%t%i%d", so the logprefix is the same as before.
New tokens can be easily added or changed if needed.

floppy_bootsig_check: disabled=[0|1]. It is not disabled by default.
Sorry for any inconvenience it could cause
- changed the default (if cmos reg is 0) behavior for the floppy boot signature
check, so the new bios is compatible with older bochs binaries (useful if we
want to use the new bios when we release 1.4.1) :
1 : disabled
0 : enabled
- added info at launch time about the boot device and the floppy boot signature
check
- added a "LBA capable" flag in the ata controller
- fixed opened netdevice name (/dev/net/tun...)
- fixed test on iface name (tun instead of tap)
- cosmetic changes
- added example in .bochsrc
Much of these fixes have been contributed by Frederic Bothamy
Here are the patches (without the serial name fix). Let me know if you want
me to change that. Oh, FYI, my changes also open up the com1 terminal in raw
mode, which makes the emulation much more accurate. You'll also notice that
I added infrastructure for com2->4 in the option parsing. I didn't add it to
the serial code, as I think a bunch of things need to be untangled before
that can work.
interface menus. Parallel port #1 is implemented, and I left stubs for
parallel port #2 in case we want to ever add it. If the parallel port
is enabled, the init method of parallel.cc does an fopen() on the output
file. If disabled, or if the fopen fails, the file handler remains
NULL and no characters are printed. There is no attempt to enable/disable
the operation of the parallel port, only the output to a file.
BX_SUPPORT_APIC were used. To follow the pattern used by other
names like this, I changed them all to BX_SUPPORT_APIC.
Thanks to Tom Lindström for chasing this down!

- 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.
what action to take on panic, error, info, and debug. The lines don't
have any effect quite yet because of an initialization order problem
with the logfunctions.
