2017.04.11
Brief summary :
- CPU: implemented new instructions and x86 architecture extensions.
- Bugfixes for CPU emulation correctness.
- Added Android host platform support.
- Added USB EHCI device emulation support.
- Added USB floppy (UFI/CBI) support.
- Added ethernet module 'socket', designed to interconnect Bochs instances.
- Show textconfig at runtime in the Bochs VGA window (gui console).
Detailed change log :
- General
- Added new log action "warn", designed to show a message box on error
events.
- Show message box before exit if log action is set to "fatal".
- Added macro BX_FATAL for all cases when continuing is not recommended,
since it can cause an application crash or incorrect simulation behaviour.
- Configure and compile
- Added Android host platform support.
- Configure script now prints warnings for features not maintained yet.
- GUI and display libraries
- Show the runtime configuration in the Bochs VGA window (gui console)
instead
of console / xterm (rfb, sdl, sdl2, vncsrv and X11 guis).
- SDL2: Added get/set clipboard text support.
- CPU / CPUDB
- Bugfixes for CPU emulation correctness (critical bugfix for x86-64 and
AVX opcodes emulation,
fixed assertion failures in proc_ctrl.cc)
! VMX: Implemented Page Modification Logging (PML)
! VMX: Implemented TSC Scaling Extension
! Paging: Implemented Protection Keys
! Implemented UMIP: User Mode Instruction Prevention (don't allow execution
of SLDT/SIDT/SGDT/STR/SMSW with CPL>0)
! Implemented RDPID instruction
! Implemented VPOPCNTD/VPOPCNTQ AVX512 instructions
! Implemented XSAVES/XRSTORS instructions and IA32_XSS MSR
! Implemented Translation Cache Extensions (TCE) for AMD CPUID and EFER.TCE
control
! Implemented CLZERO instruction (AMD), enabled in Ryzen CPU model
! Implemented MONITORX/MWAITX instructions (AMD), enabled in Ryzen CPU model
! CPUDB: Added AMD Ryzen configuration to CPUDB
- I/O Devices
- Busmouse
- Added standard bus mouse support in addition to the existing InPort
emulation code. (patch by Ben Lunt).
- Hard drive
- Implemented lock mechanism for hard disk images. An image that is opened
in r/w mode cannot be used multiple times (e.g. by another Bochs
session).
- Several fixes in some disk image modes.
- Serial / Parallel ports
- Added support for changing output file at runtime.
- Networking
- Added ethernet module 'socket', designed to interconnect Bochs instances
with external program 'bxhub' (simulating a multi-port ethernet hub).
- Now creating separate plugins for each network driver implementation
(slirp, win32, etc.).
- Sound
- Added PCM output data resampling in a separate thread. The resampler
requires either libsamplerate or the SoX resampler library installed.
- SDL: Added audio capture support (requires library version >= 2.0.5).
- Now creating separate plugins for each sound driver (alsa, win, etc.).
- USB
- Added USB EHCI device emulation support (EHCI core ported from Qemu).
- Added USB floppy (UFI/CBI) support (patch by Ben Lunt).
- Added asynchronus USB packet completion support (needed by disk/cdrom
seek and read/write latency emulation).
- Implemented USB remote wakeup mechanism.
- Fixed NAK response handling in all USB HCs.
- USB printer: added support for changing output file at runtime.
- Added common USB device option "debug" to turn on BX_DEBUG reporting at
connection time.
- ROM BIOS
- Implemented Bochs BIOS option "fastboot" for skipping the boot menu delay.
