|
- Bugfixes for CPU emulation correctness and stability
|
|

|
|
|
|
- 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.
|
|

|
|
- 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).
