* It seems that NetBSD/i386 and amd64 do not boot on this version of bochs...
Changelog:
Changes in 2.6 (September 2, 2012):
Brief summary :
- More than 10% CPU emulation speedup !
- Support for AMD's SVM hardware emulation (including extended XAPIC support).
- Implemented support for new x86 ISA extensions.
Bochs is fully aligned with rev043 of Intel(R) Architecture Manual.
- Improved emulation accuracy (critical fixes for APIC, VMX and AVX/XOP emulation).
- Bochs internal debugger: new command to show state of a device from the debugger.
- ROM BIOS: improved PCI boot ROM support (for VGA and other devices)
- Networking:
- Ported Intel(R) 82540EM Gigabit Ethernet adapter emulation from Qemu.
- Added PCI network boot ROM support to all network adapters.
- Added TFTP support to the 'slirp' networking module.
- Harddrive: added support for VirtualPC disk images, fixed sparse disk images.
- Sound:
- implemented PC speaker beep using the lowlevel sound interface.
- SDL audio output support.
- Added ability to set log action per device from .bochsrc.
- Moved disk imaging, networking, sound and USB devices to subdirectories
in the iodev folder.
Detailed change log :
- CPU
- Implemented EPT A/D extensions support.
Bochs is fully aligned with rev043 of the of Intel(R) Architecture Manual.
- Implemented ADX (ADCX/ADOX) instructions support, the feature can
be enabled using .bochsrc CPUID option.
- More than 10% CPU emulation speedup with even more optimal lazy flags
handling, stack access optimizations and cross branch trace linking.
- Support for AMD's SVM hardware emulation in Bochs CPU, to enable
configure with --enable-svm option
- Implemented AMD Extended XAPIC support, to enable set .bochsrc CPU
APIC option to 'xapic_ext'
! Added Corei5 750 (Lynnfield) configuration to the CPUDB
! Added Turion64 (Tyler) configuration to the CPUDB
! Added AMD Phenom X3 8650 (Toliman) configuration to the CPUDB
! Added Corei7 3770K (Ivy Bridge) configuration to the CPUDB
- Bugfixes for CPU emulation correctness and stability
(critical fixes for APIC/X2APIC, VMX and AVX/XOP emulation)
- Bochs Debugger and Instrumentation
- Implemented new debugger command 'info device [string]' that shows the
state of the device specified in 'string'
- Improved debug dump for ne2k, pci, pic and vga/cirrus devices. Added
debug dump for pci2isa, i/o apic, cmos, pit, floppy and dma devices.
- Added TLB to CPU param tree - now it can be browsed from Bochs internal
debugger and Bochs debugger GUI through param tree interfaces
- Implemented 'writemem' debugger command to dump virtual memory block
starting from selected linear address into a file
- Updated definition of instrumentation callbacks, see description in
instrumentation.txt / Fixed instrumentation examples
- Configure and compile
- Moved disk imaging, networking, sound and USB devices to subdirectories
in the iodev folder.
- pcidev: enable support for Linux kernel 3.x (Debian patch by Guillem Jover)
- debugger: generate parser / lexer files only if all required tools are present
- Config interface
- Added support for direct device plugin loading with bochsrc directive for
devices which have the same name for the plugin and config option.
- The bochsrc option 'plugin_ctrl' can now be used to load/unload optional
plugins directly when parsing the config file or command line. See the bochsrc
sample for supported devices.
- Moved bochsrc parsing / writing and config parameter handling for networking,
sound and USB devices to the plugin device code. The options are only
available when the corresponding plugin device is loaded.
- Added ability to set log action per device from .bochsrc.
- Added new command line option '-noconsole' to disable the console
window on Windows host.
- Renamed PCI Pseudo NIC option to "pcipnic" (for direct plugin loading)
- Moved several related options to the new "keyboard" bochsrc option.
- Added new parameter 'rtc_sync' for the 'clock' option. If this option
is enabled together with the realtime synchronization, the RTC runs
at realtime speed.
- Moved MWAIT_IS_NOP bochsrc option from CPUID to CPU so it can be set
even if cpu was configured using pre-defined CPUDB profile.
- Allow larger CPU 'quantum' values when emulating SMP systems for speed
(quantum values up to 32 are allowed now).
- I/O Devices
- Networking
- Ported Intel(R) 82540EM Gigabit Ethernet adapter emulation from Qemu,
to enable configure with option --enable-e1000
- Added PCI network boot ROM support to all network adapters
- Added TFTP support to the 'slirp' networking module
- PCI
- added "auto-assign to PCI slot" feature for PCI-only devices
- DMA
- Added the capability to transfer more then one byte / word per ISA DMA cycle
- VGA
- Major rewrite of the vga / cirrus code:
- vgacore (shared standard VGA emulation code)
- vga (Bochs VBE and PCI VGA)
- cirrus (CL-GD 5430 ISA / CL-GD 5446 PCI)
- Added VGA graphics blinking support
- More accurate vertical and horizontal retrace emulation
(based on the DOSBox implementation)
- hard drive / hdimage
- added new disk image mode 'vpc' for VirtualPC images
- undoable mode: added coherency check (flat image size and timestamp)
- sparse mode: fixed read support
- Sound
- implemented PC speaker beep using the lowlevel sound interface
- added SDL audio output support
- ROM BIOS
- improved PCI boot ROM support (for VGA and other devices)
- added MADT entry for Interrupt Source Override to ACPI tables
- GUI and display libraries
- implemented "auto-off" timer for status LEDs indicating a data transfer
- Added support for sending absolute mouse position values from the gui if an
absolute pointing device (USB tablet) is active (rfb, sdl, win32, wx, x).
- Gui debugger now supported when using sdl gui on Windows
- Implemented "hideIPS" option in rfb, sdl, win32 and wx libraries
- wx: fixed random freezes with wxGTK and "show ips" feature enabled
- rfb: the "show ips" feature now works on Windows host
- Tools
- bxcommit: added support for converting growing to flat mode images
- bxcommit: support command line options and non-interactive (quiet) mode
- bximage: increased maximum disk size to 8 TB
