Richard Hughes: Synaptics CX Audio Support

Filed under
Linux
GNOME

So, after all that we got down to a 1377 line fwupd plugin which is a 16x code reduction. It’s broadly comparable in functionality to the 22,000 line code drop but only works in fwupd as a plugin rather than as a standalone updater. To add support for new hardware to the plugin all we have to do is add an entry to the quirk file, which tells us which CX family the specific USB VID/PID is using. The rest is auto-detected.

I can’t tell you the OEM or the hardware all this work is being driven by, but eagle-eyed readers will work it out Smile In some cases you might see an extra device appear in fwupdmgr get-devices if you’re running the soon-to-be-released fwupd 1.3.2 and hopefully we can get firmware updates which use this new device on the LVFS some time this year.

  • Fwupd Gaining Support For Synaptics/Conexant CX Audio Firmware Updating

    Fwupd is gaining the ability to update firmware on Synaptics/Conexant CX audio devices commonly used by laptops.

    Fwupd/LVFS lead developer Richard Hughes has been working on adding support for CX audio device support following Synaptics providing him with a code drop for demonstrating the support.

Open source technology, enabling innovation

One of the most exciting projects to come out of the open source revolution is Kubernetes, a tool helping companies running their software on cloud services. It enables them to get the most out of the processing power they’re paying for by identifying machines that are being underutilised. So, if the software detects that a machine is not being optimised, it will load it up with another task so it’s working as hard as it can. Read more

Forbes Raves Upcoming Linux Desktop will enclose Windows 10 and macOS

Forbes senior employee Jason Evangelho dedicated an entire article to an upcoming update for a Sino-domestic Linux distribution: If you haven't paid attention to a bit of Linux desktop distribution called Deepin, it's time to put it on your radar. Remember that Huawei Deepin chose to ship on their MateBook laptop lineup. Remember that Deepin Cloud Sync (for system settings) is a great, progressive feature that every Linux distro must use. Remember that the retractable control center from the future looks like something sexy and sensible. But looking at 2020, Deepin is absolutely breathtaking. This is without a doubt the nicest desktop environment I have ever seen … For me, the UX is more intuitive and pleasant than macOS and Windows 10. And luckily a quick setting can also transform Deepin into the traditional Windows or macOS desktop paradigm's that you are already familiar with. Hell, even the installer is a relief.

[libre-riscv-dev] power pc

So as you know, the RISCV Foundation is seriously impeding progress. There
is huge momentum around RISCV itself, however as far as open *innovation*
is concerned, the sheer arrogance of the Foundation in failing to respect
the combination of Libre goals and business objectives has us completely
isolated from key critical resources such as the closed secret lists and
wiki.

We cannot even get access to documentation explaining how to propose new
extensions.

I have been considering for some time to reach out to MIPS and PowerPC.
Yesterday I wrote to the OpenPower Foundation and was really surprised and
delighted to hear back from Hugh Blemings, whom I worked with over 20 years
ago.

I outlined some conditions (no NDAs, open mailing lists, use of
Certification Marks and Compliance Suites) and he replied back that this
was pretty much along the lines of what they were planning.

I will have a chat with him some time, in the meantime I found the spec:

https://openpowerfoundation.org/?resource_lib=power-isa-version-3-0

It is eeenooormous, however Hugh reassures me that they want to break it
into sections.

Why would we even consider this?

The lesson from RISCV is really clear: if the ISA is set up as a cartel,
Libre innovation is not welcome.

If we had a goal to just *implement* a *pre existing* Extension, there
would be no problem.

It is the fact that we wish to implement entirely new extensions, for CPU
and GPU *and* VPU purposes, but not as a separate processor (which would be
classified as "custom") that is the "problem".

So starting at page 1146, we need to work out how to shoe horn a ton of
stuff into the ISA, as well as fit 16 bit compressed in as well.

Calamares grabs onto things

I’ve been working on Calamares, the Universal Linux Installer, for a little over two years – following up in the role Teo started. It’s used by Neon (for the dev version, not the user version) and Manjaro and lots of other Linux distributions. I’ve typically called it an installer for boutique distro’s, as opposed to the Big Five. Well, Debian 11 has plans. And lubuntu uses it as well (and has for over six months). Those seem pretty big.
