- Implemented EPT A/D extensions support.
Bochs is fully aligned with the latest published revision of
Intel Architecture Manual (revision 043) now.
stack direct access optimization - 5% emu speedup to all 32-bit guests, for 64-bit guests speedup is less because they have less stack accesses
2012-03-25 15:54:32 +04:00
- Another 10% CPU emulation speedup with even more optimal lazy flags
handling and stack access optimizations

debug dump for pci2isa, i/o apic, cmos, pit, floppy and dma devices.
surprisingly, opensuse 12.1 requre alignment check support in hardware so I can't disable it by default for all configurations. but in case you want a few %% of extra emulation performance - it is still possible to disable it with configure option. most guests I saw do not use it !

- update changes
2012-03-13 23:08:40 +04:00
- Configure and compile
- Do not compile support for alignment check (#AC exception) by default for CPU emulation performance reasons, the alignment check compilation still can be enabled using configure option --enable-alignment-check. There is no software in the world which enable #AC exception checking, this x86 feature is completely legacy but its emulation support costs up to 3-5% emulation speed. The checking for #AC exception enable still will be done, if CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1 but the alignment check is not compiled in, the Bochs will PANIC with corresponding message. You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.
2012-03-25 23:07:17 +04:00
- Moved networking, sound and USB devices to subdirectories in iodev.
dump CPUID .bochsrc options only if no CPUDB profile is selected
2012-03-15 23:55:14 +04:00
- Moved MWAIT_IS_NOP .bochsrc option from CPUID to CPU so it can be set
- Do not compile support for alignment check (#AC exception) by default for CPU emulation performance reasons, the alignment check compilation still can be enabled using configure option --enable-alignment-check. There is no software in the world which enable #AC exception checking, this x86 feature is completely legacy but its emulation support costs up to 3-5% emulation speed.

2012-03-25 23:07:17 +04:00
even if cpu was configured using pre-defined CPUDB profile.
bx_instr_mem_data_access became completely obsolete with new stack optimization merged into SVN. It already had limited usability before. With stack direct access optimization the callback won't be called for stack accesses as well. See note by Brian Slechta: === Cut Hete === While using Bochs as a reference model for simulations, the simulator needs information about what loads/stores are taking place with each instruction. Presumably, that is what the BX_INSTR_MEM_DATA() instrumentation macros cover (which is the place where our simulator hooks up). The RETnear_xxx() functions call access_linear() directly, rather than call read_virtual_xxx() functions. This is a problem for code making use of the BX_INSTR_MEM_DATA() hook because it does not get called for these instructions. Should this be changed along with some other instructions that exhibit this? === Cut Hete === For Bryan's usage bx_instr_lin_access and bx_instr_phy_read/bx_instr_phy_write callbacks should be used.
2012-04-11 23:01:25 +04:00

Update CHANGES
2011-02-27 22:10:14 +03:00
Updating CHANGES for coming 2.5 release It was a real challenge to summarize all the highlights we have done in past half a year. Hopefully it looks good and I didn't miss anything important.
2011-09-26 02:15:21 +04:00
Bochs repository moved to the SVN version control !
Brief summary :
Supply real VMX capabilities together with the CPU MODEL .bochsrc option. So now the same single option will choose not only the CPUID flags but also VMX capabilities matching real HW machine. Removed cpuid of core2_extreme_x9770 from the cpudb. I don't remember its VMX capabilities anyway. There is another Penryn model in the cpudb - core2_penryn_t9600.
2011-09-26 16:31:40 +04:00
! Fully configurable CPU to emulate with a single .bochsrc option !

- CPU
update CHANGES
2011-07-29 19:55:17 +04:00
- Now you can configure CPU to emulate using a single .bochsrc option !
The option selects CPU configuration to emulate from pre-defined list
of supported configurations. When this option is used, Bochs CPU emulation
engine is automatically configured to emulate a specific real hardware CPU,
added atom n270 cpuid + small fixes
2011-08-03 21:49:49 +04:00
including exact CPUID matching reference hardware. Check .bochsrc example
added FMA4 AMD instructions support, fixed mem access length for Intel scalar FMA instructions
2011-10-07 18:09:35 +04:00
or check user manual for list of supported configurations and more details.
added new bochs binary param to choose cpu to emulate
2011-08-17 00:30:01 +04:00
* It is also possible to choose the CPU to emulate from Bochs command line
fixed for gather VSIB calculation
2011-08-29 00:14:53 +04:00
using command line interface to .bochsrc: "cpu::model <cpu_name>"
* Query for supported CPU models using command line option: -help cpu.
- 10% emulation speedup with handlers chaining optimization implemented. The feature is enabled by default when configure with --enable-all-optimizations option, to disable handlers chaining speedups configure with --disable-handlers-chaining
2011-08-21 18:31:08 +04:00
- 10% emulation speedup with handlers chaining optimization implemented. The
feature is enabled by default when configure with --enable-all-optimizations
option, to disable handlers chaining speedups configure with
--disable-handlers-chaining
- New way of CPUs scheduling in SMP mode brings up to 50% speedup to the SMP emulation. New implementation uses dynamic CPU quantum value and takes full advantage of the trace cache. Each emulated processor will execute the whole trace before switching to the next processor. * It is also safe to use large (up to 16 instructions) quantum values for the SMP emulation now and improve performance even further. The same merge also completely fixes SF bug : [3312237] stepN command might be not working properly Handlers chaining speedups are also supported with SMP emulation now.

[3422638] large ramfile support broken on anything but Linux
- New way of CPUs scheduling in SMP mode brings up to 50% speedup to the SMP emulation. New implementation uses dynamic CPU quantum value and takes full advantage of the trace cache. Each emulated processor will execute the whole trace before switching to the next processor. * It is also safe to use large (up to 16 instructions) quantum values for the SMP emulation now and improve performance even further. The same merge also completely fixes SF bug : [3312237] stepN command might be not working properly Handlers chaining speedups are also supported with SMP emulation now.

- NMI virtualization, APIC virtualization not implemented yet
- VMENTER to not-active state not supported yet
- No advanced features like Extended Page Tables or VPID
Added ability to define user MSRs spec for emulated CPU
2008-12-28 23:30:48 +03:00
- Support for configurable MSR registers emulation, to enable configure with
--enable-configurable-msrs option
Look for configuration example in .bochsrc and msrs.def

2002-12-16 11:49:37 +03:00
- add a little summary at the top
2002-12-19 04:33:24 +03:00
Since the change log is hundreds of lines long, here is a very brief summary.
- 2x emulation speedup!!!
- added plugin devices and guis. Now you can compile with many more
options, and choose between them at runtime.
- added emulation of AMD x86-64, MMX, SSE, SSE2 instructions
- add wxWindows port (a graphical configuration interface and display lib)
and SVGAlib port (full screen display for Linux without X11)
- improvements in many I/O devices: for example up to 8 hard disks/cdroms,
TUN/TAP network interface, 360k floppies,
- improved MacOSX/Carbon interface and updated MacOS9 port
- GDB remote stub, allows symbolic debugging with Bochs simulation.
- support for up to 32gig hard disk images
Detailed change log follows.

2002-12-21 18:54:39 +03:00
docs-html (Bryce)
- doc/docbook/Makefile is now generated by configure script.
if configure detects docbook2html on your system, it will turn on
--enable-docbook and run make in the doc/docbook directory. Also
make install will install documentation into $(docdir). You can use
--disable-docbook to turn this off, if necessary. (Bryce)
- add "make bochsdoc.tar.gz" target to create a documentation tarball.
If you do "make webinst" and you have write access on SF shell server,
it updates doc/docbook/* on the website (Bryce)
- user documentation additions:
- new options (Bryce, Volker, Christophe)
- Bios tips section (Christophe)
- Tuntap section (Christophe)

- add more about plugins, bochsrc, wxWindows - merge in contents of an email from Volker
2002-12-16 23:10:58 +03:00
- Plugins are shared libraries that can be loaded on demand. Example:
the serial device is implemented as a plugin. In UNIX, the
serial plugin is called libbx_serial.so. When Bochs reads its
configuration file, if the serial device is enabled it loads
libbx_serial.so.

Cygwin using dlltool. On MacOSX, you must have dlcompat installed
and in your include/library paths at configure time. (See .conf.macosx
for an example.)

critical bug fixes (Bryce Denney)
- add more about plugins, bochsrc, wxWindows - merge in contents of an email from Volker
2002-12-16 23:10:58 +03:00
- the Linux binary RPMs are built with plugin support
- to compile with plugins, configure with --enable-plugins
- finish going through Makefile.in
2002-12-17 23:09:44 +03:00
- the LTDL_LIBRARY_PATH variable tells Bochs where its plugins can be
found. Bochs has a compile-time default for this variable which is
correct if you do a make install. You would only need to set the
variable if the default is wrong.
- finish up with main directory, mark it done - add notes about dlcompat on macosx, libtool ltdl, DLL building on win32 - add x86-64 notes from Peter Tattam - add PSE,PGE,PAE in cu section - specify some of those carbon improvements based on reading logs - update to-do list
2002-12-18 01:41:52 +03:00
- for win32 plugins we added "BOCHSAPI" in front of many classes
and methods, to aid in building DLLs. This turns into __declspecs
which are used when making an export library for Bochs.
- finish going through debug/* logs - finish going through configure.in logs - update to-do list
2002-12-17 19:08:10 +03:00
- allow many display libraries to be configured and compiled at
a time. For example --with-win32 --with-sdl --with-rfb.
Also, we added an experimental option --with-all-libs which
tries to detect which --with-* options will work. If the
autodetection fails, just type the --with-* options explicitly. (Bryce)
- add a sort of framework for rel2.0 changes to fit into
2002-12-16 11:49:37 +03:00
- add #if's around all files which are conditionally compiled such
as cdrom.cc and sb16.cc. This makes it possible to compile every
source file all the time, which has the potential to simplify the
configure script and makefiles. At present we only take advantage

- finish going through debug/* logs - finish going through configure.in logs - update to-do list
2002-12-17 19:08:10 +03:00
- keep separate CFLAGS and CXXFLAGS for Bochs (usually a graphical
program) and console programs such as bximage and niclist. Some
sdl and wx compile flags were making bximage and niclist unusable.(Bryce)
- add concept of cross-configuring in the configure script. If you
use the --target option to generate makefiles to be used on another
machine, some detection of compilers and libraries is disabled. (Bryce)
- fix term compile on Cygwin, but it has to be done without -mno-cygwin,
which means that several win32 features such as networking do not work.
- add "-Wno-multichar" on beos
- test for largefile support, and add required CFLAGS (Bryce)
- add -lm when it's needed, and not when it's not (Bryce)
- add configure support for 8 processors. Bochs can support up to 15
with some work on the BIOS.
- fix nmake makefile generation (Psyon)
- improved pthread detection function from ac-archive project on SF
- add first names to first reference of each developer - fix some FIXMEs - move documentation section to the top - move wxWindows after config interface and display library sections - remove the massive list of SF bugs,features,etc. since they have (mostly) been covered above - erase to-do list since it's done

- Even though we've had them for years, the term "display library" is new in
release 2.0. In the gui directory, Bochs has a number of different C++
files which you can select to display the text and graphics on the
simulated monitor. Each of these is a display library. The display
libraries are:
x use X windows interface, cross platform
win32 use native win32 libraries
carbon use Carbon library (for MacOS X)
beos use native BeOS libraries
macintosh use MacOS pre-10
amigaos use native AmigaOS libraries
sdl use SDL library, cross platform
svga use SVGALIB library for Linux, allows graphics without X
term text only, uses curses/ncurses library, cross platform
rfb provides an interface to AT&T's VNC viewer, cross platform
wx use wxWindows library, cross platform
nogui no display at all

display libraries such as SDL which have a full screen mode can be
dangerous, if Bochs does not switch back to normal display mode at
the right time. This is fixed for SDL and the new svga.

- renamed almost all references to data type "Boolean" to "bx_bool".
The Boolean data type was defined in Carbon.h headers, and conflicted
with Bochs's definition. See bug [ 618388 ] Unable to boot under MacOS X
Exceptions: When talking to the Carbon library, you must use Boolean.
Also, siminterface.h uses standard "bool" instead of bx_bool.

- wxWindows
- wxWindows is a cross-platform C++ user interface library which you can
download for free at http://wxwindows.org. wxWindows provides C++
classes for all sorts of GUI controls (buttons, menubars, etc.) and
implements all of them using the native controls on the platform.
- The new wxWindows port of Bochs provides both a graphical configuration
interface (for editing bochsrc options) and a display. It was
written by Bryce Denney, Don Becker, Dave Poirier, and Volker Ruppert.
- In release 2.0, we concentrated on making the wxWindows port as stable
and functional as the other interfaces. wxWindows provides a great
toolbox that we can use to make Bochs easier to learn and use.
- wxWindows supports charmap changes, keyboard mapping, cut and paste,
text and graphics modes, text mode cursor size, and mouse (Volker, Bryce)
- To compile Bochs with wxWindows, you should install wxWindows 2.3.3
or later. Then configure Bochs with --with-wx.
- if you have multiple versions of wxWindows installed (e.g. a debug

2002-03-28 04:20:31 +03:00
Changes in 1.4 (March 27, 2002):
- ROM BIOS
- Boot from CDROM! Christophe Bothamy added partial El Torito support in
rombios.c, which allows Bochs to boot cdroms. Booting from win2k or winXP
cdrom is not supported yet. The default BIOS includes El Torito functions.
the boot line must say "cdrom".
Example:
boot: cdrom

-------------------------------------------------------------------------
- update for 1.3
2001-12-11 00:53:21 +03:00
Changes in 1.3 (December 10, 2001):
- touch up, move things around
2001-12-06 06:51:55 +03:00
- networking works on Windows and Linux platforms
- emulated cdrom can now read from ISO image files, on any platform.
- new PIT model by Greg Alexander which is much more complete than the
whitespace cleanup for CHNAGES
2008-02-07 09:24:57 +03:00
old one. The new PIT is used by default, but you can switch back to
- touch up, move things around
2001-12-06 06:51:55 +03:00
the old one if you configure with --disable-new-pit.
(PIT = 8254 programmable interrupt timer)
- new configuration menus by Bryce Denney, which allow you to change any
bochsrc option using text menus, then save the configuration into
a new bochsrc file for later use. You can disable the new code using
configure --disable-control-panel. Also you can use the command
line arguments -nocp or -nocontrolpanel. Also, there is a new
whitespace cleanup for CHNAGES
2008-02-07 09:24:57 +03:00
"Config" button on the GUI that allows limited changes to the
- touch up, move things around
2001-12-06 06:51:55 +03:00
configuration at runtime, such as changing the floppy disk.
- add docbook documentation directory in the sources under doc/docbook.
The transition from HTML to docbook documentation is still in progress.
- Add new log action "ask", as shown in these example bochsrc lines:
- I'm working on change log for version 1.3. Not complete yet.
2001-12-05 20:37:08 +03:00
panic: action=ask
error: action=ask
When an event occurs which is set to "ask", you get a beep and message
on the text terminal that asks what you want to do. Choices are: continue,
continue and disable future messages from this device, quit immediately,
or segfault (where abort() function is available). If compiled with
--enable-debugger, you can also choose to enter the debugger.
- Parallel port emulation cleaned up by Volker Ruppert. See .bochsrc for
syntax of new parport1 line in bochsrc.
- made it through the whole cvs log, whew!
2001-12-06 01:12:59 +03:00
- PCI support improved by Volker Ruppert, including BIOS changes. Still
not complete.
- touch up, move things around
2001-12-06 06:51:55 +03:00
- floppy controller returns a proper error response if you try to write
a read-only disk image. For systems such as DOS that actually use the BIOS
services, it was also necessary to add code in int13_diskette_function to
recognize a write-protected error and return the correct error status code
(AH=3, Carry Set).
- the ROM BIOS now prints panic messages to the console. Thanks to Cliff
Hones for his console display code.
- the ROM BIOS detects nonbootable disks (Barry Allard), and prints a message
on the console. Barry Allard's patch who helped with checking the boot

signature.
- I'm working on change log for version 1.3. Not complete yet.
2001-12-05 20:37:08 +03:00
- LBA support added for hard disks. (Not tested very much.)
- add dependencies to makefiles
- logging code moved into a separate file, logio.cc
- new option --enable-slowdown-timer, by Greg Alexander, which kicks in if
Bochs simulation time starts to run faster than real time. This helps to
keep the Bochs clock in sync with the real clock when the CPU is mostly
idle.
- new option --enable-iodebug, by Dave Poirier, which creates an I/O
interface to the debugger. This lets you write software to be emulated
in Bochs which can turn on instruction, register, or memory tracing
using I/O accesses.
- improved detection of readline in configure script
- configure substitutes the version number into many files, instead of
using sed in the makefile. There are still a few uses of sed remaining.
- you can now use environment variables in bochsrc values. For example,
diskd: file="$BOCHS_IMG/diskd.img", cyl=615, heads=6, spt=17
- configure with --prefix=PATH works now

a patch from Edouard G. Parmelan
- I'm working on change log for version 1.3. Not complete yet.
2001-12-05 20:37:08 +03:00
- fix [ #433759 ] virtual address checks can overflow.
> Bochs has been crashing in some cases when you try to access data which
> overlaps the segment limit, when the segment limit is near the 32-bit
> boundary. The example that came up a few times is reading/writing 4 bytes
> starting at 0xffffffff when the segment limit was 0xffffffff. The
> condition used to compare offset+length-1 with the limit, but
> offset+length-1 was overflowing so the comparison went wrong.
- cmpxchg8b patch from Michael Hohmuth <hohmuth@innocent.com>
- apply patch from Thomas Fitzsimmons <fitzsim@cygnus.com> to fix compile
problems when BX_SUPPORT_PAGING and BX_USE_TLB are turned off
- fix bug introduced in 1.2.1 which caused spurious exceptions.
See patch #439314, Exception 1 (debug) on HALT, from
thomas.petazzoni@meridon.com.
- add panic in ctrl_xfer32.cc where the IRET32 implementation is broken.
This only happens if you are NOT in vm8086 mode or protected mode.
The intent is to warn people when they are getting bad emulation, and
encourage people to report how they got to that point.
- touch up, move things around
2001-12-06 06:51:55 +03:00
- apply patch from Santiago Bazerque. See this bug report:

2001-12-05 20:37:08 +03:00
[ #463018 ] retf not removing parameters sometimes
- fix bug [ #461730 ] IRETD causes problems if NT-flag is set
reported by Peter Lammich.
- apply patch [ #455014 ] CR0 bug in 80486, described as:
> In the register CR0, when the bit PM is enabled, the bit 4 is 0
> when should be 1.
- apply patch from Mike Rieker <mrieker@o3one.org> associated with this bug
report: [ #480422 ] gdt 'accessed' bit
- in task_switch when it tried to ensure that the old TSS was paged in,
it actually used the new TSS address, fixed.
- made it through the whole cvs log, whew!
2001-12-06 01:12:59 +03:00
- updated the instrumentation code, and added a working example. To try
it, configure --enable-instrumentation=instrument/example1. Then when
you run bochs, you will get one line for each instruction PC and for
each I/O access in a new file called bxevent.txt.
- set a bit in the CMOS that says the processor has an FPU. This is
from patch [ #455006 ] Device byte is not initialized aptly.
Author did not leave their name.
- add logging code to the "null ethernet" which does not require host OS
support. All this does is print the outgoing packets from the guest OS.
- cleanup of log functions (Todd Fries)
- add BX_ERROR for every command in ATAPI-6 that bochs does not support.
I still need to do add some commands from older specs that are obsolete
(and not listed) in ATAPI-6. Commands that aren't in the spec will still
panic.
- only put 0xf into the 2nd hard disk field when the cdrom is not present.
This is a patch from Volker Ruppert <Volker.Ruppert@t-online.de>, who
comments: "The fdisk command reports an unusable second harddisk if the cdrom
is enabled. This patch helps, but I don't know if it is the right way."
- make hard disk code return error codes when data is not available instead
of just panicing. In particular, if the logical sector is out of bounds
or the disk image cannot be read/written at the desired offset, we now
abort the ATA command and return an error code. Many of the old BX_PANIC
messages are turned to BX_ERROR, so they will still appear in the
log, but now the device model will try to communicate this fact to
the OS instead of simply giving up.
- don't blindly reject odd length atapi commands. There are cases when
it's really ok according to ATA-4.
- for big endian machines, reversed the bit fields in interrupt_reason.
This was pointed out by Nicholai Benalal.
- extended keyboard improvements by Dave Poirier

- now Windows 95/98/ME can read the physical cdrom (Don Becker)
- The default configuration for Win32 VC++, given in .conf.win32-vcpp,
now enables the NE2000 and renames all .cc files to .cpp. This keeps VC++
happy but may make it hard to use CVS.
- The default configuration for Cygwin, given in .conf.win32-cygwin, now
enables cdrom and SB16.
- See "new docs" on the web site for compile instructions for VC++ and Cygwin.
- The sources include a VC++ workspace, in addition to the old "nmake"
makefile.
- ethernet support (emulated NE2000 card), coded by Don Becker. This

- new utility called niclist.exe which lists the ID number of all your network
cards (well probably you just have one). The ID be used when setting up your
.bochsrc.
- patch [ #466403 ] make text colors more accurate. The author did not leave
his/her name.
- fix GUI bug [ #452159 ] win32: mouse stuck if bochs win partly off screen
Now we center the mouse periodically, whether or not the mouse has
wandered outside of the window or not.

2001-12-05 20:37:08 +03:00
- The default configuration for Linux, given in .conf.linux, now enables
the NE2000 model.
- RPM build process configures with --prefix=/usr so that everything is
installed in /usr/bochs instead of /usr/local/bochs.
- DLX Linux disk image is now installed so that only root can write it, to
avoid security problems. When you run the bochs-dlx script, it creates a
local copy in your home directory and then runs it.

> The Linux 2.4.5 CD-ROM driver sends a READ_DISC_INFO command which caused
> an "unrecognized ATAPI command" panic. Looks like READ_DISC_INFO is only

do "info all" you get cpu and fpu registers.
- added debugger command "info ne2k" which prints all the registers
of the NE2000 model
- add ability to do register tracing and flag tracing (Dave Poirier).

2001-06-13 01:56:59 +04:00
Changes in 1.2.1 (June 12, 2001):
- more work on makefile for building RPMs
- [ #432382 ] build debian packages patch
add build/debian directory from Rob Lemley <rjlemley@calypsoblue.org>
which allows us to make Debian packages!
- optimize for speed when simulating one processor. Now 1-processor
performance should be equivalent to 1.1.2.
- [ #425640 ] sb16 assumes fpos_t is long int
This fixes compiles of iodev/sb16.cc on linux systems with newer libraries
in which fpos_t is not an integer.
- [ #432488 ] SMP:assert "n_logfn < MAX_LOGFNS" fails
increase MAX_LOGFNS since we ran out of them on an SMP simulation with
4 processors
- changes to compile clean on cygwin:
- don't use the WIN32 snprintf define for cygwin
- add ssize_t definition for cygwin
- only compile "struct timeval tval" if select is available
on that platform.
- [ #432491 ] SMP: CPUID says no APIC feature
clean up inconsistent use of BX_SUPPORT_APIC and BX_APIC_SUPPORT, which
caused the CPUID to report no APIC was present
- [ #431025 ] --enable-external-device-models broken
whitespace cleanup for CHNAGES
2008-02-07 09:24:57 +03:00
removed configure options for external-device-models and

external-cpu-memory. These don't work and aren't going to be fixed.
- [ #429448 ] configure: -lreadline when not there
Now configure allows you to choose not to use readline, even if it's found
on your system.
- [ #428915 ] apply extended keyboard patch
extended keyboard patch by Dave Poirier <eks@void-core.2y.net>
- [ #428626 ] if no X11 found, configure&make fails
Now configure halts if X windows is selected but no X libraries are found.
- updated rombios to version 1.13. This fixes several problems:
- [ #430472 ] DOS HIMEM "A20 line" error
This problem was apparantly caused when Bryce added a function that prints

preventing SMP operating systems from detecting that other processors
were available.
- [ #431016 ] bios: SMP struct has wrong entry count
SMP structure had the wrong entry counts
- very minor doc updates (typos, replace broken link to mtools info)
- quit when the user clicks the power button, even if they have disabled
panics.
- win32 now defaults to having mouse capture mode turned off. For new users,
it would be distressing for their mouse cursor to disappear until they
pressed F12.
- [ #428222 ] vga font not installed
added script called "install-x11-fonts" which should help people install
the VGA font on X windows systems, if it isn't already there.

Changes in 1.2 (June 3, 2001):
- move to CHANGES, to be consistent with README, COPYING
2001-06-02 12:20:55 +04:00
- [ #427259 ] rombios HALT calls don't print
Fixed bios/rombios.c HALT macro so that it writes the line number of the
whitespace cleanup for CHNAGES
2008-02-07 09:24:57 +03:00
panic to the PANIC_PORT (port 0x400) and then does NOT do a halt
- move to CHANGES, to be consistent with README, COPYING
2001-06-02 12:20:55 +04:00
instruction. Also changed iodev/unmapped.cc so that the line number written
to PANIC_PORT is displayed as a BX_PANIC message. Because the HALT
macro now triggers the normal panic behavior, it can be controlled by
the bochsrc.
- [ #429016 ] crash if no hard drive
rombios used to call HALT macro if no hard drive was found. Now it only
calls HALT if a hard drive has an illegal geometry.
- [ #425388 ] include source for simple disk img tool
[ #428478 ] mkimg tool creates image 1 byte too big
Added bximage tool, which makes empty floppy and hard disk images.
It is now included in the top level Makefile, so it will get built
by default on all platforms.
- [ #426036 ] eth_fbsd.cc compile problem on solaris26
added configure test so that "configure --enable-ne2000" only
includes the Berkeley Packet Filter code (eth_fbsd) if the header
file <net/bpf.h> can be found. If you don't have BPF the ne2000
will not actually move packets, but at least it will compile clean now.
- [ #428214 ] 1.2.pre1 need documentation for binaries
Write windows and linux specific documentation to be installed in
binary releases.
- [ #429258 ] disable RESET for version 1.2
Since soft reset was not completely working, I reverted the reset patch.
Now it does panics on reset instead of trying to reboot, as the old
bochs versions did.
- [ #428222 ] Should the linux RPM install vga font?
now font/vga.pcf will be installed in the RPM package
- [ #429020 ] stop renaming the BIOS!!!

2008-02-07 09:24:57 +03:00
new BIOS changes are now in BIOS-bochs-latest, instead of a BIOS

2001-06-02 12:20:55 +04:00
whose name changes every time we change anything! To help distinguish
different BIOS versions, the BIOS now prints its RCS Id into the
log file.
- [ #428625 ] compile problem if SHOW_IPS is on
removed extra paren that broke SHOW_IPS
- [ #428219 ] PCI doesn't compile with SMF=1
- [ #429375 ] pthreads detection broken
- [ #429073 ] configure: if no X11, makes bad config
- [ #429229 ] install current .bochsrc in binary rels

2001-06-04 08:23:39 +04:00

- move to CHANGES, to be consistent with README, COPYING
2001-06-02 12:20:55 +04:00
- BIOS prints messages in log in case of boot failure
- rewrote instructions for compiling in win32 (win32.txt)
- fixed link in HTML changelog.html to point to the real sources on SF.
- added missing LOG_THIS definition to gui/nogui.cc and gui/rfb.cc
- added additional check for null pointer in debugger exit routine
- added diskd to .bochsrc

- update for version 1.2-pre1
2001-05-25 17:53:06 +04:00
- major cleanup of .bochsrc
- major cleanup of stderr output: prints bochs version information when

hard drives and a cdrom at the same time, because there is only
one IDE controller with two channels.
- split hard disk support allows different partitions to be stored in
different image files
- two new GUI choices: term mode and RFB mode. Term is a text-only
interface, and RFB creates a server that can be accessed using
the AT&T VNC viewer.
- now Bochs can simulate an SMP machine, if you configure with
--enable-processors=N. Configuring more than one processor has
a major performance impact, so the default is 1 processor.
See SMP documentation for more details.
- to make SMP work, bx_mem and bx_cpu have been replaced with
bx_mem_array[] and bx_cpu_array[]. The cpus are referenced through
the BX_CPU(n) macro and memories through the BX_MEM(n). Normal

- update for version 1.2-pre1
2001-05-25 17:53:06 +04:00
one memory, cosimulation mode has multiple cpus and multiple memories.
- use --enable-cpu-level=6 to make Bochs claim to be a Pentium Pro.
The only feature that requires CPU level 6 is apic support.
- new logging system by Todd Fries, which has 4 levels of event
severity (panic, error, info, debug). There are new .bochsrc
whitespace cleanup for CHNAGES
2008-02-07 09:24:57 +03:00
options that control what action to take when a

- now searches for .bochsrc, bochsrc, bochsrc.txt, and (on unix only)
$HOME/.bochsrc.
- use GNU readline library if --enable-debugger is on, as long as readline
can be found on the machine

- applied patches from Cliff Hones <cliff@aonix.co.uk> to fix up the
rombios. This includes many improvements, which you can list by
doing "cvs log -r 1.6 bios/rombios.c" or looking at cvsweb.
- added suggested geometries of larger disks to the documentation
- this is the first release to have official binary packages for win32
and Linux. There is a new "make rpm" in the top-level Makefile which
will create an RPM of the current bochs directory. To use this,
become root and type "configure; make rpm".
- applied some FreeBSD patches from Maxim Sobolev (cdrom and serial).

- brought in from 1.1 branch
2001-05-18 01:55:42 +04:00
- updated Elpin VGA BIOS to version 2.40, and changed pointer in .bochsrc
- fixed .conf.x86 script so that it uses c++ instead of egcs for C++ files
- now Makefile targets that recurse into subdirectories use double colons,
so that it will always recurse into subdirectories. Now a single make
command should notice a modified source file in a subdir.

- redefine u_char, u_short, etc. in order to not conflict with system
definitions of these same types.
- in cdrom.cc, remove the extern "C" { } structure around some of the
header files. This is no longer necessary.
- do not panic on hard disk command 0x1f2 (read sector count)
- in keyboard.cc:
- apply Todd Fries' reset patch
- recognize most of the "Grey" insert/delete/home/end/etc. keys the
same as keypad keys.
- removed panic on "kbd_ctrl_to_kbd(): got value of 0x??"
- implement mouse command 0xf6 (set defaults)
- apply Suboner@aol.com's Xwindows timing patch from
http://sourceforge.net/tracker/index.php?func=detail&aid=418730&group_id=12580&atid=312580
- remove all patches from patches subdir which have already been applied.
