Changes in 2.6.7 (November 2, 2014): - CPU / CPUDB - Implemented AVX-512BW/AVX-512DQ/AVX-512VL extensions emulation. - implemented AVX512-IFMA532 instructions emulation. - implemented AVX512-VBMI instructions emulation. - Bugfixes for CPU emulation correctness (critical fixes for AVX-512, CMPXCHG16B and VMX) - Fixed Bochs segmentation fault crash with Handlers Chaining Speedups enabled when compiling with gcc, especially with low optimization levels. - Reverted removal of reporting Architectural Perfmon support in pre-defined CPUID modules. Windows 8 and Windows 10 require Performance Monitoring to be reported to boot. To workaround possible Windows 7 64-bit installation issues: use bx_generic CPUID module, which doesn't report Performance Monitoring in CPUID. - GUI and display libraries - The VGA update timer and the status LED timer now always use the realtime mode independent from the 'clock' option setting. - Added native SDL2 GUI support to Bochs. To enable configure with --with-sdl2. - Added new user shortcut "scrlck" (SDL/SDL2 using "Scroll Lock" for fullscreen toggle). - Write enhanced gui debugger settings to file on exit and restore on initialization. - I/O Devices - USB - xHCI model now emulates a NEC/Renesas uPD720202 device (patch by Ben Lunt). - Added USB port specific option 'size' for VVFAT disks (range 128M ... 128G). If the size is not specified or invalid, it defaults to 504M. - Hard drive / HD image - Fixed crash when using a "fixed" type VPC image. - ROM BIOS - Fixed int74_function() for 4-byte (wheel mouse) packets. - LGPL'd VGABIOS updated from CVS (fixed building VBE modes list) - Misc - Visual Studio workspace files updated to VS2013Ex format. - bximage_old/bxcommit: removed old obsolete image manipulation tools. - Documentation fixes and updates.
