Venus on QEMU: Enabling the new virtual Vukan driver

Friday 26th of November 2021 11:08:15 PM
Running graphics applications on a virtual machine can be annoying as they are generally greedy of computing resources, and that can slow you down or give you a bad experience in terms of graphics performance. Being able to accelerate all this by offloading the workload to the hardware can be a great deal. The VirtIO-GPU virtual GPU device comes into play here, allowing a Guest OS to send graphics commands to it through OpenGL or Vulkan. While we are already there with OpenGL, we can not say the same for Vulkan. Well, until now.

  • Linux Fixes Spectre V1 SWAPGS Mitigation After Being Partially Borked Since Last Year - Phoronix

    This week's set of "x86/urgent" changes for the Linux 5.16-rc4 kernel due out later today has some Spectre V1 fixes after kernel commits last year ended up partially messing things up around its SWAPGS handling. These fixes in turn will also likely be back-ported to relevant stable kernel series. Thanks to an Alibaba engineer, Lai Jiangshan, are some important fixes around the Spectre V1 SWAPGS mitigation that are landing today in the mainline kernel.

  • Reproducible Builds: Reproducible Builds in November 2021

    As a quick recap, whilst anyone may inspect the source code of free software for malicious flaws, almost all software is distributed to end users as pre-compiled binaries. The motivation behind the reproducible builds effort is therefore to ensure no flaws have been introduced during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised. If you are interested in contributing to our project, please visit our Contribute page on our website.

  • Reproducible Builds (diffoscope): diffoscope 195 released

    The diffoscope maintainers are pleased to announce the release of diffoscope version 195. This version includes the following changes:

    [ Chris Lamb ]
    * Don't use the runtime platform's native endianness when unpacking .pyc
      files to fix test failures on big-endian machines.
    

Linux 5.16-rc4

Fairly small rc4 this week. Three areas stand out in the diff: some
kvm fixes (and tests), network driver fixes, and the tegra SoC sound
fixes.

The rest is fairly spread out: drm fixes, some filesystem stuff,
various arch updates, and some smattering of random driver fixes.

Nothing looks all that scary, although I certainly hope the kvm side
will calm down.

EFF Argument in Patent Troll Case to Be Livestreamed on Monday

At 10 am Monday, FOSS folks and others interested in software patent litigation will have a chance to have a firsthand look at how our courts address patent cases. The case involves a “notorious patent troll,” according to Electronic Frontiers Foundation, that is trying to hide information from Apple, which it’s suing. “At a federal appeals court hearing that will be livestreamed, attorney Alexandra H. Moss, Executive Director at Public Interest Patent Law Institute, who is assisting EFF in the case, will argue that a judge’s order to unseal all documents and preserve public access in the case of Uniloc USA, Inc. v. Apple Inc. should be upheld,” EFF said in a statement on Thursday. “Uniloc is entitled to resolve its patent dispute in publicly-funded courts, Moss will argue, but it’s not entitled to do so secretly.” EFF said that this is the second time the plaintiff, Uniloc, has appealed an order to be more transparent in this case.

Gnuastro 0.16 released

Dear all,

I am happy to announce the 16th official release of GNU Astronomy
Utilities (Gnuastro version 0.16).

Gnuastro is an official GNU package, consisting of various
command-line programs and library functions for the manipulation and
analysis of (astronomical) data. All the programs share the same basic
command-line user interface (modeled on GNU Coreutils). For the full
list of Gnuastro's library, programs, and a comprehensive general
tutorial (recommended place to start using Gnuastro), please see the
links below respectively:

https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html

For a complete review of the new/changed features in this release,
please see [1] below (also available in the 'NEWS' file within the
source code tarball).

Here is the compressed source and the GPG detached signature for this
release. To uncompress Lzip tarballs, see [2]. To check the validity
of the tarballs using the GPG detached signature (*.sig) see [3]:

  https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.16.tar.lz    (3.7MB)

  https://ftp.gnu.org/gnu/gnuastro/gnuastro-0.16.tar.lz.sig (833B)

Here are the SHA1 and SHA256 checksums (other ways to check if the
tarball you download is what we distributed). Just note that the
SHA256 checksum is base64 encoded, instead of the hexadecimal encoding
that most checksum tools default to.

guidelines, run the relevant programs with a `--cite' option (it can
be different for different programs, so run it for all the programs
you use). Citations _and_ acknowledgments are vital for the continued
work on Gnuastro, so please don't forget to support us by doing so.

This tarball was bootstrapped (created) with the tools below. Note
that you don't need these to build Gnuastro from the tarball, these
are the tools that were used to make the tarball itself. They are only
mentioned here to be able to reproduce/recreate this tarball later.
  Texinfo 6.8
  Autoconf 2.71
  Automake 1.16.4
  Help2man 1.48.5
