Changelog:
Changes in 2.6.9 (April 9, 2017):
Brief summary :
- CPU: implemented new instructions and x86 architecture extensions.
- Bugfixes for CPU emulation correctness.
- Added Android host platform support.
- Added USB EHCI device emulation support.
- Added USB floppy (UFI/CBI) support.
- Added ethernet module 'socket', designed to interconnect Bochs instances.
- Show textconfig at runtime in the Bochs VGA window (gui console).
Detailed change log :
- General
- Added new log action "warn", designed to show a message box on error events.
- Show message box before exit if log action is set to "fatal".
- Added macro BX_FATAL for all cases when continuing is not recommended, since
it can cause an application crash or incorrect simulation behaviour.
- Configure and compile
- Added Android host platform support.
- Configure script now prints warnings for features not maintained yet.
- GUI and display libraries
- Show the runtime configuration in the Bochs VGA window (gui console) instead
of console / xterm (rfb, sdl, sdl2, vncsrv and X11 guis).
- SDL2: Added get/set clipboard text support.
- CPU / CPUDB
- Bugfixes for CPU emulation correctness (critical bugfix for x86-64 and AVX opcodes emulation,
fixed assertion failures in proc_ctrl.cc)
! VMX: Implemented Page Modification Logging (PML)
! VMX: Implemented TSC Scaling Extension
! Paging: Implemented Protection Keys
! Implemented UMIP: User Mode Instruction Prevention (don't allow execution of SLDT/SIDT/SGDT/STR/SMSW with CPL>0)
! Implemented RDPID instruction
! Implemented VPOPCNTD/VPOPCNTQ AVX512 instructions
! Implemented XSAVES/XRSTORS instructions and IA32_XSS MSR

(slirp, win32, etc.).
- Sound
- Added PCM output data resampling in a separate thread. The resampler
requires either libsamplerate or the SoX resampler library installed.

- Now creating separate plugins for each sound driver (alsa, win, etc.).
- USB
- Added USB EHCI device emulation support (EHCI core ported from Qemu).
- Added USB floppy (UFI/CBI) support (patch by Ben Lunt).
- Added asynchronus USB packet completion support (needed by disk/cdrom
seek and read/write latency emulation).

-------------------------------------------------------------------------
Changes in 2.4 (May 3, 2009):
Brief summary :
- Added graphical Bochs debugger frontend for most of the supported platforms.
- Thanks for Chourdakis Michael and Bruce Ewing.
- Many new CPU features in emulation
- Support for > 32 bit physical address space and configurable MSRs
- VMX, 1G pages in long mode, MOVBE instruction
- Bugfixes for CPU emulation correctness, debugger and CPU instrumentation.
- New config interface 'win32config' with start and runtime menu
- USB: added OHCI support, external hub and cdrom
- Added user plugin interface support.
Detailed change log :
- CPU and internal debugger
- Support for VMX hardware emulation in Bochs CPU, to enable configure with
--enable-vmx option
Nearly complete VMX implementation, with few exceptions:
- Dual-monitor treatment of SMIs and SMM not implemented yet
- NMI virtualization, APIC virtualization not implemented yet
- VMENTER to not-active state not supported yet
- No advanced features like Extended Page Tables or VPID
- Support for configurable MSR registers emulation, to enable configure with
--enable-configurable-msrs option
Look for configuration example in .bochsrc and msrs.def
- Support new Intel Atom(R) MOVBE instruction, to enable configure with
--enable-movbe option
- Support for 1G pages in long mode, to enable configure with
--enable-1g-pages option
- Support for > 32 bit physical address space in CPU. Up to 36 bit could be
seen in legacy mode (PAE) and up to 40 bit in x86-64 mode.
Still support the same amount of the physical memory in the memory object,
so system with > 4Gb of RAM yet cannot be emulated.
To enable configure with --enable-long-phy-address option.
- Implemented modern BIOSes mode limiting max reported CPUID function
to 3 using .bochsrc CPU option. The mode is required in order to
correctly install and boot WinNT.
- Added ability to configure CPUID vendor/brand strings through .bochsrc
(patch from @SF by Doug Reed).
- Many bugfixes for CPU emulation correctness (both x86 and x86-64).
- Updated CPU instrumentation callbacks.
- Fixed Bochs internal debugger breakpoints/watchpoints handling.
- Configure and compile
- Added ability to choose Bochs log file name and Bochs debugger log file
name from Bochs command line (using new -log and -dbglog options)
- Removed Peter Tattam's closed source external debugger interface from
the code.
- Removed --enable-guest2host-tlb configure option. The option is always
enabled for any Bochs configuration.
- Removed --enable-icache configure option. The option is always enabled
for any Bochs configuration. Trace cache support still remains optional
and could be configured off.
- Added configure option to compile in GUI frontend for Bochs debugger,
to enable configure with --enable-debugger-gui option.
The GUI debugger frontend is enabled by default with Bochs debugger.
- Removed --enable-port-e9-hack configure option. The feature now could be
configured at runtime through .bochsrc.
- Added configure option to enable/disable A20 pin support. Disabling the
A20 pin support slightly speeds up the emulation.
- reduced dependencies between source files for faster code generation
- BIOS
- Added S3 (suspend to RAM) ACPI state to BIOS (patch by Gleb Natapov)
- Implemented MTRR support in the bios (patches by Avi Kivity and Alex
Williamsion with additions by Sebastian Herbszt)
- Bug fixes
- I/O Devices
- Added user plugin support
- remaining devices converted to plugins: pit, ioapic, iodebug
- added 'plugin_ctrl' bochsrc option to control the presence of optional
device plugins without a separate option. By default all plugins are enabled.
- added register mechanism for removable mouse and keyboard devices
- Hard drive / cdrom
- PACKET-DMA feature now supported by all ATAPI commands
- ATAPI command 0x1A added (based on the Qemu implementation)
- sb16
- Added ALSA sound support on Linux (PCM/MIDI output)
- FM synthesizer now usable with MIDI output (simple piano only)
- Fixed OPL frequency to MIDI note translation
- Fixed MIDI output command
- keyboard
- added keyboard controller commands 0xCA and 0xCB
- USB
- USB code reorganized to support more HC types and devices
- added USB OHCI support written by Ben Lunt
- added external USB hub support (initial code ported from Qemu)
- added USB cdrom support (SCSI layer ported from Qemu)
- added status bar indicators to show data transfer
- VGA
- VBE video memory increased to 16 MB
- implemented changeable VBE LFB base address (PCI only, requires latest
BIOS and VGABIOS images)
- I/O APIC
- implemented I/O APIC device hardware reset
- Config interface
- new config interface 'win32config' with start and runtime menu is now
the default on Windows ('textconfig' is still available)
- win32 device config dialogs are now created dynamicly from a parameter list
(works like the wx ParamDialog)
- changes in textcofig and the wx ParamDialog for compatibility with the new
win32 dialog behaviour
- Bochs param tree index keys are case independent now
- some other additions / bugfixes in the simulator interface code
- Misc
- updated LGPL'd VGABIOS to version 0.6c
- Updated Bochs TESTFORM to version 0.4

to handle this, but it is good (and simple!) enough for now. It'd be
improved by moving some more files around and trying to make it more
consistent with "regular" installs.
The problem is that the build results are completely different under OS X
than those produced in other systems.
Not bumping PKGREVISION because this was unbuildable before.

-------------------------------------------------------------------------
Changes in 1.4.1 (June 22, 2002):
- now cdrom is enabled in configure, unless you specifically disable
it with --disable-cdrom. (Christophe)
- fix compile error in main.cc when SMP or APIC is enabled (Dave)
- the runtime menu now displays 11 (continue) by default (Bryce)
- initialize DMA controller before floppy and SB16
- fix DMA panic when installing win95 (Volker)

Before, it was incorrectly coded as a '@'.
- AltGr key on European keyboards works now on win32 (Volker)
- fix problem with console/serial port on Bochs exit (Volker)
- enable serial port for GNU and GNU/Linux (Volker)
- small documentation fixes (Volker)
- remove unnecessary include statements for X11 (Volker)

that are less than 60 bytes long. (Peter Tattam)
- BIOS fixes :
- win2k cd-boot (Christophe)
- emm386 crash (Dave)
- cs=0 at boot time (Christophe)
- keyboard failure in scandisk (Dave)
- fix bug in forming the 64-bit APIC base address from two 32-bit registers.
A compiler warning in cpu/proc_ctrl.cc pointed this out.
- fix default choice in the runtime options menu

It can boot a Norton Utilities CD, but not run any of the
utilities. That may be the known problem with the Windows 98 CD.
- - Add the ability, on NetBSD, to spin up the CD-ROM. This keeps
"disklabel cd0" while booted from the NetBSD 1.5.3 rescue floppy
from panicing the emulation, but it still doesn't return a label.
- - Go ahead and enable the network driver and dummy sound driver.
The network driver almost works under the NetBSD rescue floppy
(ifconfig works, but not ping). I have no way, currently, of
verifying the (dummy, silent) sound driver.
- - Bump to 1.4nb1.

of the more visible ones.
- ROM BIOS
- Christophe Bothamy added ability to boot from El Torito CDROM.
- VGA
- vga memory read/write functions in text mode fixed
- implementation of CGA mode 320*200*4 (patch from Sebastien Bechet)
- GUI changes
- cdrom button: click this to notify Bochs when you changed the CDROM (Volker)
- snapshot button: saves the text on the Bochs screen into a file called
snapshot.txt (Volker)
- copy button: on Win32 and X windows, copy the text on the Bochs screen
to the clipboard (Volker)
- paste button: on Win32 and X windows, paste the characters on the
clipboard into the Bochs window. This requires keyboard_mapping to
be enabled. (Bryce Denney)
- keyboard
- added an optional keyboard_mapping option that enables to use your
country specific keyboard with Bochs. If enabled, the keymap file must be
specified in bochsrc. The available keymaps are US, German, Spanish and
French for PCs running X11. Contributions are welcomed. (Christophe
Bothamy)
- added Windows(tm) key definitions (Volker Ruppert)
- added paste button, which causes the emulated keyboard to type characters
from the system clipboard. This only works when keyboard_mapping is
enabled. (Bryce Denney)

stable than, version 1.1.2. Extensive changes include a new text-based
configuration menu (which starts at launch and upon pressing the config
button), LBA support for hard disks, better error handling for "hard
disk" configuration errors, and a new VGABIOS (optional). Plus, bochs
can now simulate an SMP machine! [The last is not tested on NetBSD,
and is not enabled by default in the package.]
|
|
- 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.
- fixed bug in bx_panic. If BX_PANIC_IS_FATAL==0 and a (non-fatal) panic
occurs, it used to call bx_atexit() and then return. It should never
call bx_atexit, which starts to shut down the simulator, unless it's
really going to quit!
- support 2.88 MB floppy disks
- since dataseghack is checked in as non-executable, invoke it with
"csh dataseghack"
- double fault patch from Thomas Petazzoni <thomas.petazzoni@ifrance.com>,
sourceforge patch #423726.
- removed -fno-builtin from fpu makefiles
- 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.
The remaining ones are under consideration but not applied.
