bx_shadow_num_c able to handle pointers to 64 bit values. This
allows x86-64 and wxWindows to coexist.
- I had a number of duplicate constructors for bx_shadow_num_c,
with an without the description arg. I eliminated the ones
that had no description, and also removed the min/max arg from
all. I still need a bunch of constructors though, for
Bit64u*, Bit64s*, Bit32u*, Bit32s*, Bit16u*, Bit16s*, Bit8u*, Bit8s*.
Having all these constructors allows us to write
new bx_shadow_num (bxid, name, description, &value)
for basically any integer variable. They are all handled by the same class.
- these changes led to minor touchups in cpu/init.cc and iodev/keyboard.cc
- modified:
configure main.cc cpu/init.cc iodev/keyboard.cc
gui/siminterface.cc gui/siminterface.h
X11 keymap files. This okay since the keysym values are identical. The "AltGr"
key on European keyboards doesn't work with wxGTK 2.3.3 because the keysym
GDK_Mode_switch is not handled in wxGTK.
- German keymap table for wx and wxgtkkeys.h are no longer needed
There was a POTENTIAL RISK for your HARDDISKS with the previous
patch because it updated the concat_image_t object (BX_SPLIT_HD is on
by default). The behaviour of BX_SPLIT_HD is to open all filenames
incrementing the last letter. Guess what follows /dev/hda ?
You may now access block devices from within bochs, only
if --disable-split-hd is configured.
It has only been tested on linux and a WinNT guest.
There are issues with the current bios CHS translating scheme and
the guest OS translating scheme. For example my compaq system translates
a physical 38792/16/63 20GiB harddrive to
a logical 2586/240/63, which does not follow the bitshift algorithm.
I had to find a different PCHS that would translate in a compatible LCHS
I still have to investigate further, but I'm afraid everything I can do
will break some systems or the others.
Those issues should be explained in the documentation.
created in the first rev. When you're talking to Carbon libraries,
of course you should use Boolean instead of bx_bool. My global
search and replace missed such subtleties.
This avoids naming conflicts, since no other library is likely to
use bx_bool.
- I will apply this before release 2.0, but not until the feature freeze
has begun, because it will break almost every patch.
different versions of the code for wxWindows and non-wxWindows and the GDB
stub did not accept any command line options at all.
- IMPORTANT CHANGE: the quick start option used to cause two things:
1) read the bochsrc immediately, 2) start simulation immediately without
going into the config interface. This has changed in a subtle way.
Now, we always try to read the bochsrc immediately. Then if the quick
start option is on, we start the simulation immediately.
- add "Restore Factory Default Configuration" in text config menu. It was
already there in wx. Now the default choice is always "5. Begin simulation"
and because the bochsrc is always read now, this works.
- When the user chooses "Read configuration file" from either text mode
or wx interfaces, reset all bochs parameters first, then read in the
new file. This means that every time you read a configuration file
you are starting from a consistent "blank slate".
- move much of the code from bx_do_text_config_interface into bx_init_main
so that wxWindows and non-wxWindows code uses the same logic. There was
only a tiny bit left in bx_do_text_config_interface so I eliminated it.
- move the "help" message into a separate function print_usage()
- detect all flags (cmdline args that start with -) in a loop, instead of
a big if/else. This makes it easy to add others.
- fix problem with Carbon gui, so that -psn arg gets ignored
- print usage if you type -h, --help, or if flags are not recognized
- code that called io->set_log_action (that sets the log action for all
devices) was only called if the configuration interface was on; I'm not
sure why. Now it is called all the time.
- the wxWindows equivalent of main() is called MyApp::OnInit. Now OnInit
and main() are very similar. They both call bx_init_siminterface, then
bx_init_main (and quit if it fails), then show the config interface if
quickstart is off, and then simulate.
- modified: main.cc gui/control.cc gui/wxmain.cc
- default value of the sequencer reset bits is 1 (no reset)
- sequencer reset flag 1 resets the charmap select register when cleared
- skip the screen update when the sequencer is in reset mode (h/v sync and
video ram refresh are disabled in that case)
- don't clear the memory update flag before the update is done
- skip the text screen update when the character height is set to 1 (MSL = 0)
- sequencer debug messages updated
SSE/SSE2 for Stanislav. Also, some method prototypes and
skeletal functions in access.cc for read/write double quadword
features.
Also cleaned up one warning in protect_ctrl.cc for non-64 bit compiles.
There was an unused variable, only used for 64-bit.
This card has 2 ata channels, so this would be better
than the promise DC2300. It also has drivers for win95,
available on tekram website.
Many thanks to Volker for fixing the interrupt bug!
It solved the problem I had with this patch...
