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
'vga_update_interval' option. The screen update frequency is still based on
the emulated clock unless the realtime sync is enabled with the 'clock' option.
TODO: rewrite the virt_timer code to support realtime screen updates
independent from 'clock' setting.
- fixed changing parameter 'update_freq' at runtime (timer object and blink counter)
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
The ACPI support is always automatically compiled in if PCI is compiled in.
The ACPI still could be disabled using .bochsrc 'plugin_ctrl' option.
Updated CHANGES and docs as well.
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.
recent version of Slirp with Debian patches applied. On a Linux host the
guest OS can access the internet without running Bochs with root privileges.
TODO:
* rewrite the DHCP part of eth_vnet.cc that it can be used here, too
* Slirp doesn't compile on 64-bit Linux with GCC 4.5
* WIN32 is not supported yet
