Bochs 2.6.10 to be Released

The new version of the system for emulation of the x86 architecture brings a lot of changes
02 December 2019   177

After two and a half years of development, the release of the Bochs 2.6.10 emulator is presented. Bochs supports emulation of CPUs based on x86 architecture, from i386 to the current x86-64 models of Intel and AMD processors, including emulation of various processor extensions (VMX, SSE, AES, AVX, SMP, etc.), typical input / output devices and peripheral devices (emulation of a video card, sound card, Ethernet, USB, etc.). Under the control of the emulator, OSs such as Linux, macOS, Android, and Windows can be launched. The emulator is written in C ++ and distributed under the LGPLv2 license.

Key changes:

  • CPU: Bugfixes for CPU emulation correctness (critical bugfixes for PCID, ADCX/ADOX, MOVBE, AVX/AVX-512 and VMX emulation)
  • CPU: implemented AVX-512 VBMI2/VNNI/BITALG, VAES, VPCLMULQDQ / GFNI instructions emulation
  • VMX: Implement EPT-Based Sub-Page Protection - CPUID: Added new CPU models Skylake-X, Cannonlake and Icelake-U
  • CPUID: Implemented side-channel attack prevention reporting and corresponding MSR registers, enabled for Icelake-U 
  • Added basic support for the i440BX PCI/AGP chipset.
  • Added basic Voodoo Banshee / Voodoo3 emulation support.
  • Added basic DDC support for the VGA-compatible adapters.
  • Implemented HPET emulation (ported from Qemu).

VirtualBox 6.1 to be Available

The are a lot of changes, i.e., support for hardware mechanisms proposed in the fifth generation of Intel Core i (Broadwell) processors was added
12 December 2019   72

After a year of development, Oracle has released the release of its VirtualBox 6.1 virtualization system. Ready-made installation packages are available for Linux (Ubuntu, Fedora, openSUSE, Debian, SLES, RHEL in assemblies for the AMD64 architecture), Solaris, macOS, and Windows.

Major changes:

  • Added support for hardware mechanisms proposed in the fifth generation of Intel Core i (Broadwell) processors for organizing embedded launch of virtual machines;
  • Removed the old 3D graphics support method based on the VBoxVGA driver. For 3D, it is recommended to use the new VBoxSVGA and VMSVGA drivers;
  • In VBoxSVGA and VMSVGA drivers, support for YUV2 and texture formats using this color model is added when using OpenGL on the host side (on macOS and Linux), which enables 3D video acceleration due to the removal of color space conversion operations to the GPU side. Solved problems with compressed textures in OpenGL when using 3D mode in the VMSVGA driver;
  • Added a software on-screen keyboard with support for multimedia keys, which can be used as a keyboard in guest OSs;
