loaded in bochsrc with "plugin_ctrl" or with their own name, the user plugin
option and the special cases for PLUGTYPE_USER are no longer needed. Updated
example patch to make it work with the latest SVN code.
This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,
TODO: hdimage and bximage code, harddrv and USB disk emulation, BIOS.
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
- added 'wavein' parameter to specify the wave input device if necessary
- if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
- SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
- TODO: implement 'wavemode' feature for ES1370 similar to SB16
- added 'sound' option to select the driver and the wave output device
(see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly
- removed parameter "present" and use the new drive type "none" instead
- re-implemented cdrom media status parameter as a bx_param_enum_c
- TODO: change floppy media status parameter type to be consistent
fixed enabling of ADX extensions in generic CPUID when enabled through .bochsrc
Small code cleanups on the way to implementation of APIC Registers Virtualization features disclosed in recent Intel SDM rev043
I am merging the code in order to start making shortcuts between VMX emulation and SVM emulation.
Of course SVM emulation is incomplete, completely untested and not expected to work.
But someone could already take a look one the code and give some suggestions.
Also looking for anybody with existing SVM kernels - as simple as possible - for testing.
Status:
- exceptions intercept is not implemented yet
- IO intercept is not implemented yet
- MSR intercept is not implemented yet
- virtual interrupts are not implemented yet
- CPUID is not implemented yet
No advanced SVM featurez planned - I am implementing the very basic 'Pacifica' document from 2005 using QEMU code as reference.

32-bit CPU using Bochs binary compiled with x86-64 support.
The commit also fixes some init.cc issues with initialization of SYSCALL/SYSRET MSR in AMD hosts and also includes code reorg.
with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.
- Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
instructions support can be enabled using .bochsrc CPUID option.
Selecting CPU MODEL from .bochsrc automatically chooses real HW CPUID and also configures Bochs emulator to emulate this specific CPU including all its features only.
Supported CPUs to choose from:
core2_extreme_x9770
corei7_sandy_bridge_2600K
p4_prescott_celeron_336
connected device. For now this feature is only used by the 'disk' device to
specify an alternative redolog filename of some image modes.
- added new methods set_option() and timer() to the base class usb_device_c.
The timer() method is periodicly called from the HC's frame timer code.
- moved runtime device change stuff from the parameter handler to the end of
timer() methods of all hubs. This makes sure that all parameters for the
device have been set at connect time. TODO: this technique could also be used
for the floppy and cdrom media change.
the SF patch #1539417, but rewritten from scratch (patch too old). Differences
to the original version:
* internal parameter name "readonly"
* update parameter if floppy image is readonly
* wxWidgets support
* documentation updates
* no specific toolbar buttons
