To enter break point, you need to run a m68k program in Macintosh guest OS. The program
executes a new emul_op instruction 0x7138. The program will be provided
in cxmon/utils folder in a separate commit. Once emulation is suspended,
you can enter below new cxmon command to manipluate break points:
ba [address] Add a break point
br [breakpoints#] Remove a break point. If # is 0, remove all break points.
bd [breakpoints#] Disable a break point. If # is 0, disable all break points.
be [breakpoints#] Enable a break point. If # is 0, enable all break points.
bi List all break points
bs "file" Save all break points to a file
bl "file" Load break points from a file
Once emulation PC reach break point address, it automatically suspends
and traps into cxmon.

ucontext_t is what POSIX requires; glibc no longer provides struct
ucontext as of 2.26: https://sourceware.org/glibc/wiki/Release/2.26
(Most architectures were already using ucontext_t, so this also makes
things more consistent; only arm and mips change.)
This should help with debugging windowing system issues, which may reside in SDL, which SDL may not provide adequate diagnostic info, or which Basilisk may not report
This change may end up being a bit slower on some systems, as the SDL backend will now render its content to two, new, SDL_Surfaces: one of which is in the guest OS' resolution, the other of which is application defined.
SDL2's SDL_Render API is used, which exposes some rudimentary elements of GPU + texture-based programming. Basilisk II now maintains a single 'SDL_Texture' object, which is an SDL representation of a GPU texture. The 'outer' surface will be used to update this texture, as requests to redraw are made.
TODO: look into removing the 'outer' SDL surface, and see if we can just copy the 'inner' surface to the SDL_Texture.
TODO: the entire SDL_Texture is updated, any time a request is made to draw. Look into minimizing this a bit.
SDL 1.x is used for display, rather than Mac OS X specific backend. If time permits, I'll port it to SDL 2, if only to reduce Basilisk's overall code foot-print.
Lots of features are apt to be disabled, as many 'dummy' backends were used.
Video-depths other than 1-bit or 32-bit are untested, and in some cases (4-bit, at least) are currently non-functional. This is due to a partial re-write of the SDL backend's blitting code, which was non-functional when low-bit-depths were used.
The SDL backend was also rewired, on OSX, to not attempt to align the display buffer on page-boundaries. So far, this doesn't seem to cause any notice-able problems, however, that's only using limited knowledge and testing (System 7.5.x does boot and display at 640x480, though!). The original display-buffer allocation code was failing to run, in some cases.
Preferences are, on Mac, currently hardcoded to be accessed at /tmp/BasiliskII/BasiliskII_Prefs. The folder, "/tmp/BasiliskII/", may be a symbolic link to elsewhere, though.
This lets you setup an environment to cross-compile, with extended support for how things will behave.
This should let the build play nicely with bitbake, without changing the --flags, and without breaking existing behaviors.
The bug was introduced by 0daa18ab2a,
which erroneously changed some signed types to unsigned types,
breaking logic involving negative numbers (e.g. when subtracting
sizes).
2. Fixed wrong use of ipip_hdr. It is for IP tunnel. This caused serious issues in IP packet filtering. Basically, it filtered out most packets sent from outsides. The correct way to get IP header destination IP address is ip_hdr.
3. Fixed ARP spoofing from guest OS to host OS. At anytime fake MAC address should be hided.
4. Changed module init and remove as non debug message.

This is useful for keeping the volume of SS/B2 separate from that of the host machine. For example, you can mute a game in SS, while still playing music on your host.
MSVC-compatible use of #pragma pack.
Fixed potential crash in Sys_open.
Use MSVC intrinsics for byte swapping.
Ensure use of winsock2 (instead of winsock).
Set appropriate architecture #defines.
Fixed various other compile warnings/errors.
* The code was hardwired for 8-bit mode, unplug that and set it up for
32bit mode (much simpler).
* You need a ROM that supports 32bit mode for now
* Mode switching not supported yet.
* Look for CPU named "amd64" as well as "x86_64"
* Don't use /dev/ptmx on FreeBSD
* On amd64 FreeBSD uses SIGSEGV, not SIGBUS
* Use MAP_FIXED to force allocations within 32-bits, it's the only way
* Need <sys/param.h> for SHMLBA
* The old offsetof() fix is no longer needed
* Preliminary work on instruction skipping
15-bit color mode is now removed on all platforms.
The removal of 15-bit color mode now happens before the sort.
Updated a variable name.
Changed list length calculation to use C++'s clever pointer
subtraction.
We want to have just one base driver that can handle both fullscreen and
windowed mode, so that we can easily switch between modes.
Create a virtual init() method to do construction, so we can move common code
from the derived classes into the base init().
Issue: https://github.com/cebix/macemu/issues/26
On non-Mac platforms, driver_fullscreen constructor sets up software cursor,
but switch_to_current_mode() ask for a hardware cursor, possibly due to a typo.
Neither one ends up being drawn, so the cursor goes invisible.
This change makes them agree to use a software cursor. We should eventually
move to just one place deciding which cursor to use, so they don't have to be
kept in sync.
Port forwarding allows the emulator to host servers that can be
accessed from outside the virtual network.
The code for parsing the preference option "redir" is adapted from
qemu code. The rest was already implemented.
This patch introduces a few changes:
1. Data of arbitrary Mac OS types which aren't handled (i.e. non text/picture types) will now be passed through to the host pasteboard, just like in the 32-bit code.
2. Reorganization of a few things.
3. Fixed a memory leak (whoops).
I'm basically submitting this patch now because I have a few other changes I'm going to try, but since I'm not sure that they're going to work, I thought it better to flush out the changes I've already made at this point first.
Thanks,
Charles
This patch fixes one lingering problem with the 64-bit clipboard code; the way it was designed, the Mac clipboard was being cleared every time a single item was being requested by GetScrap, causing clipboards with multiple items to be unceremoniously whittled down to one. On the other hand, a similar issue was causing some items to get duplicated on the host pasteboard. This patch fixes the issue by making conversion between the host pasteboard and the Mac clipboard a singular operation; when the pasteboard data changes on the host side, it is all converted and sent to the Mac pasteboard at once, and similarly, all Mac clipboard data is sent to the host pasteboard in one operation. Also, data from the host side is copied to the Mac clipboard only if it has changed since the last check, which should improve performance as conversions will not be done over and over every time the Mac side checks whether the scrap has changed.
In addition, I've added a rudimentary PICT converter. It's rudimentary at the moment, only going in one direction, converting to PICT and not from PICT, and currently it always rasterizes the source image and creates a PICT containing bitmap data. However, it's a start, and it should solve Ronald's issue with copying images from OS X to Mac OS. In the future, more could possibly be added. I've put the new PICT code in the main source directory instead of in the MacOSX subdirectory, so that it can be used by other platforms if needed.
I would like to leave the license on the new PICT code as "Public Domain" if that is okay.
Thanks,
Charles
This patch adds support for international text to Basilisk II / SheepShaver's clipboard support. Text copied on the host side is converted from Unicode to the format that the classic Mac OS Script Manager expects, with localized font variants used if they are available on the emulated system (unfortunately, if a localized font is not available, the text will render incorrectly due to the nature of the Script Manager). When text is copied on the emulated system, the script of the current font is used to determine the encoding of the text, and it is converted to Unicode to be pasted on the host side.
This patch supports copying and pasting text containing multiple scripts; for example, "EnglishČeský日本語", where ranges (0, 7) and (8, 3) are Roman, (7, 1) and (11, 1) are Central European, and (12, 3) is Japanese, can be freely copied and pasted back and forth between the host and emulated platforms, provided that the emulated platform has localized Central European and Japanese fonts installed.
In order to get this to work, I rewrote pretty much all of clip_macosx64.mm. The code now completely uses the Cocoa framework rather than CoreFoundation and Pasteboard Manager. Because this API now uses the Mac OS X 10.6+ version of the pasteboard API, the minimum version of OS X supported by clip_macosx64.mm is now 10.6. I think this shouldn't be a problem, since the 32-bit version still exists, but if this version needs to support older releases, let me know and I can add version-check code to do so. One of the benefits of using the modern API, however, is that our rich-text format is no longer hard-coded to the RTF format, which means we have automatic support for any other format used by the OS X pasteboard system, which as of Lion seems to include RTF, UTF-16 text, UTF-8 text, 'ut16'/'ustl', and others, and which may be supplemented by other formats in future releases of OS X.
I hope you find this patch useful.

./configure --enable-macosx-gui
The goal is to get rid of the build files under src/MacOSX by
allowing the ones under src/Unix to produce the same outputs.
Note: This currently has video problems, but this is consistent
with what you get when building out of src/MacOSX.
Added code to parse the Classic Mac OS 'styl' resources, allowing formatted text to be copied and pasted out of SheepShaver, not just plain text. In order to do this, I made some changes to the emul_op mechanism, patching ZeroScrap() in addition to the scrap methods that were already being patched. The reason for this is that since we need to read data from multiple items that are on the clipboard at once, we cannot simply assume a zero at the beginning of each PutScrap() operation.
This patch uses RTF to store styled text on the host side; unfortunately, since the APIs to convert to and from RTF data are in Cocoa but not in CoreFoundation, I had to write the new portions in Objective-C rather than C, and changed the extension from .cpp to .mm accordingly. In the future, if we are confident that this file will only be used on Mac OS X 10.6 and up, we can rewrite the Pasteboard Manager code to use NSPasteboardReading/Writing instead. This would allow us to read and write NSAttributedString objects directly to and from the pasteboard, which would make sure we were always using the OS's preferred rich text format internally instead of hard-coding it specifically to RTF as in the current implementation.
I believe that this patch should also fix the problem Ronald reported with copying accented characters.
Since I am new to 68k assembly and the emul_op mechanism, I would appreciate if someone could double-check all my changes to make sure that I have done everything correctly.
Thanks,
Charles
Note: Checks for __LP64__ explicitly because build/host/target
all get reported as i686-apple-darwin10.8.0 (not x86_64).
Also fixes a compile warning in clip_macosx64.cpp.
thread is currently only used to poll for CDROM devices and is not useful
when "nocdrom" is set. This change also fixes the problem of the emulator
preventing the CD to be ejected at the host level despite "nocdrom" being
set in prefs.
