6751af5d8e added AVX FMA extensions support. The implementation is based on QEMU patch by Peter Maydell (fixed) 2011-09-29 22:20:56 +00:00

62d0c8abf7 - Now you could disable x86-64 from .bochsrc so now it is possible to emulate 
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.

c419b2a672 another small smp optimization 2011-09-22 21:48:54 +00:00

1b9f286945 - New way of CPUs scheduling in SMP mode brings up to 50% speedup to the 
SMP emulation. New implementation uses dynamic CPU quantum value and takes
   full advantage of the trace cache. Each emulated processor will execute
   the whole trace before switching to the next processor.
 * It is also safe to use large (up to 16 instructions) quantum values for
   the SMP emulation now and improve performance even further.

The same merge also completely fixes SF bug :
  [3312237] stepN command might be not working properly

Handlers chaining speedups are also supported with SMP emulation now.

50207eeb90 - Added support for AMD SSE4A emulation, the instructions can be enabled 
using .bochsrc CPUID option.

44241a1e56 - Added support for AVX and AVX2 instructions emulation, to enable configure 
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.

0b670248ca - added command line option '--help cpu' that shows the list of supported cpu 
models (TODO: this could be done for devices, too)

13feb0772a - 10% emulation speedup with handlers chaining optimization implemented. The 
feature is enabled by default when configure with --enable-all-optimizations
    option, to disable handlers chaining speedups configure with
        --disable-handlers-chaining

1d89709e62 Added another CPU to CPUDB: p4_willamette (one more without x86-64 support). 
Reimplemented CPUDB using pure C macros magic.
Fixed compilation errors when compiling with SMP on.

4699840aaf - reorganisation of the vga init code: 
- using the same init() method for all display adapters
  - new method protected init_standard_vga() for the shared vga core
  - new method init_vga_extension() implements the extended features
- moved loading of vgabios image for the ISA case from main.cc to the vga init code

76c11e1a40 - Configure option --enable-acpi is deprecated and should not be used anymore. 
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.

8c32359615 The VBE display extension is now a part of the Bochs core. The configure option 
--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.
