Bochs 2.3.5 release
Stanislav Shwartsman
The intermediate (bugfix+) release Bochs 2.3.5 is out now. The sources and
binary packages for Linux and Windows are available for download. The website
and the online documentation will be updated soon.
Here brief summary of changes since release 2.3:
- Critical problems fixed for x86-64 support in CPU and Bochs internal
debugger
- ACPI support
- The release compiled with x86-64 and ACPI
- Hard disk emulation supports ATA-6 (LBA48 addressing, UDMA modes)
- Added emulation of Intel SSE4.1 instruction set
Detailed change log :
- CPU
- Fixed critical bug with 0x90 opcode (NOP) handling in x86-64 mode
- implied stack references where the stack address is not in canonical form
should causes a stack exception (#SS)
- Added emulation of SSE4.1 instruction set (Stanislav)
- Do not save and restore XMM8-XMM15 registers when not in x86-64 mode
- Fixed zero upper 32-bit part of GPR in x86-64 mode
- CMOV_GdEd should zero upper 32-bit part of GPR register even if the
'cmov' condition was false !
- Implemented CLFLUSH instruction, report non-zero cache size in CPUID
- Fixed PUSHA/POPA instructions behavior in real mode
- Fixed detection of inexact result by FPU
- Fixed denormals-are-zero (DAZ) handling by SSE convert instructions
- Implemented Misaligned Exception Mask support for SSE (MXCSR[17])
- Implemented Alignment Check in the CPU and #AC exception, to enable
use --enable-alignment-check configure option
- General
- 2nd simulation support in wxBochs now almost usable (simulation cleanup
code added and memory leaks fixed)
- Configure and compile
- several fixes for MacOSX, OpenBSD and Solaris 10
- enable save/restore feature by default for all configurations
- reorganized SSE configure options to match Intel(R) Programming
Reference Manual, new option introduced for SSE extensions enabling.
To enable Intel Core Duo 2 new instructions use
--enable-sse=3 --enable-sse-extension
enabling of SSE4.1 (--enable-sse=4) will enable SSE3 extensions as well
- removed old PIT, always use new PIT written by Greg Alexander,
removed configure option --enable-new-pit
- I/O devices (Volker)
- Floppy
- partial non-DMA mode support (patch by John Comeau)
- Hard drive / cdrom
- hard disk emulation now supports ATA-6 (LBA48 addressing, UDMA modes)
- VMWare version 4 disk image support added (patch by Sharvil Nanavati)
- PCI
- initial support for the PIIX4 ACPI controller
- Serial
- added support for 3-button mouse with Mousesystems protocol
- USB
- experimental USB device change support added
- rewrite of the existing USB devices code
- new USB devices 'disk' and 'tablet' (ported from the Qemu project)
- Bochs internal debugger
- fixed broken debugger "rc file" option (execute debugger command from file)
- implementation of a gui frontend ("windebug") for win32 started
- gdbstub now accepts connection from any host
- several documentation updates
- a lot of disasm and internal debugger x86_64 support fixes
- Configuration interface
- fixes and improvements to the save state dialog handling
- Display libraries
- text mode color handling improved in some guis
- win32 fullscreen mode (patch by John Comeau)
- System BIOS (Volker)
- 32-bit PM BIOS init code for ACPI, PCI, SMP and SMM (initial patches by
Fabrice Bellard)
- PCI BIOS function "find class code" implemented
- SF patches applied
