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   354

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).

Nuitka 0.6.6 to be Released

This compiler allows to translate a Python script into a C ++ representation, which can then be compiled into an exe file using libpython
08 January 2020   126

Nuitka 0.6.6 has been released. This is a compiler that allows you to translate a Python script into a C ++ representation, which can then be compiled into an executable file using libpython to ensure maximum compatibility with CPython (using regular CPython tools for managing objects) . Fully compatible with current releases of Python 2.x and 3.x. Compared to CPython, compiled scripts show up to 312% higher performance in pystone tests. Project code is distributed under the Apache license.

The new version adds experimental support for Python 3.8 and provides compatibility with libraries and applications sklearn, osgeo, gdal, dill, scikit-image, skimage, weasyprint, dask, pendulum, pytz and pytzdata. Distutils adds support for individual modules (py_modules, not just packages) and packages with separate namespaces. Work with variables in loops has been optimized and optimized options for the abs and all built-in functions have been implemented, as well as accelerated operations with int and long types. Numerous improvements have been made to reduce memory consumption.
In addition, it is possible to postpone the end of support for the Python 2 branch from January to April. In April 2020, the last final update of the Python 2.7 branch will be generated, after which the corrective releases will not be published. At the same time, work on fixing vulnerabilities in Python 2.7 will be continued by community representatives who are interested in continuing to support this branch in their products. For example, Red Hat will continue to maintain packages with Python 2.7 throughout the entire life cycle of RHEL 6 and 7 distributions, and for RHEL 8 it will generate package updates in the Application Stream until June 2024. Recall that the Python 2.7 branch was formed in 2010 and it was originally planned to stop supporting it in 2015, but due to the insufficiently active migration of projects to Python 3, the lifetime of Python 2 was extended to 2020.
