  • The Talospace Project: Firefox 92 on POWER

    Firefox 92 is out. Alongside some solid DOM and CSS improvements, the most interesting bug fix I noticed was a patch for open alerts slowing down other tabs in the same process. In the absence of a JIT we rely heavily on Firefox's multiprocessor capabilities to make the most of our multicore beasts, and this apparently benefits (among others, but in particular) the Google sites we unfortunately have to use in these less-free times. I should note for the record that on this dual-8 Talos II (64 hardware threads) I have dom.ipc.processCount modestly increased to 12 from the default of 8 to take a little more advantage of the system when idle, which also takes down fewer tabs in the rare cases when a content process bombs out. The delay in posting this was waiting for the firefox-appmenu patches, but I decided to just build it now and add those in later. The .mozconfigs and LTO-PGO patches are unchanged from Firefox 90/91.

  • Mozilla bypasses Microsoft, makes it easier to set Firefox as default browser in Windows

    Changing the default apps such as browsers in Microsoft Windows 10 is not a straightforward process. While this means that users have to jump through extra hoops to set up, let's say, Mozilla Firefox as their default browser, it also means that vendors such as Mozilla face more competition from Microsoft's own offering, which is Edge. The bad news is that in Windows 11, this is becoming even more cumbersome for end-users and vendors as the OS requires users to change the default browser for each type of extension individually.

  • Firefox 94 will change the output for X11 to use EGL by default

    A nightly builds build that will on the Firefox 94 release to added to the change has been include a new rendering backend by default for graphical environments that use the X11 protocol. The new backend is notable for the use of the interface for displaying graphics EGL instead of GLX. The backend supports the open source Mesa 21.x OpenGL drivers and the proprietary NVIDIA 470.x drivers. AMD proprietary OpenGL drivers are not yet supported.

  • Chrome 93 Released With WebOTP Cross-Device Support, CSS Module Scripts - Phoronix

    Google is shipping Chrome 93 today as the latest stable version of their web browser.

    Chrome 93 brings WebOTP API cross-device support to the desktop where if connected via the same Google Account across devices can seamlessly handle one-time pass-codes sent to your mobile device. Chrome 93 on the developer front also exposes the Multi-Screen Window Placement API. This new API makes it easier to manage several displays and can be used for use-cases like presentations where one display may be showing a slide deck while another display is showing the speaker notes, managing multiple windows for tool panes like for image and video editors, or virtual trading desks with showing multiple related windows. With Chrome 93 this new Multi-Screen window Placement API is exposed as an origin trial.

Running benchmarks with Vulkan in Crostini (Linux for Chrome OS) yields surprising results

We recently cracked the case of how to get Vulkan graphics acceleration working in Crostini. I’ve got a full guide on how to do this yourself coming up as my next article so stay tuned for that if you’d like to be able to tinker with this a bit yourself! With the power of Vulkan, we wanted to see how well this all performs inside and outside of a the virtualized Crostini environment. Spoiler alert: the first results aren’t great.

Let me first start with a disclaimer. There’s a reason Vulkan isn’t enabled for the masses: it’s not ready yet. We’re seeing a large performance drop comparing a game running in and outside of Crostini. This new graphics pass-through driver, code-named Venus, was only merged upstream a few months ago and is truly revolutionary. There could be lots of patches behind closed doors at Google that we don’t know about. We only have what is publicly available to us.

  • Chrome 94 Beta Released With WebCodecs API Promoted, WebGPU Origin Trial

    Google promoted Chrome 94 to beta status today with some exciting changes.

    First up, Chrome 94 Beta marks the completion of the WebCodecs API under its origin trial and thus now officially available. WebCodecs is the low-level codec API around audio/video encoding and decoding along with raw video frame handling and more. WebCodecs API handling is intended to be more efficient than JavaScript or WebAssembly codec implementations.

  • Google Working On Making VirtIO-GPU More Extensible

    Google Chrome OS engineers are working on making Linux's VirtIO-GPU driver more extensible. The VirtIO-GPU driver has been modeled around the Virgl protocol for handling 3D within guest virtual machines but with a new context type addition they aim to support additional protocols.

    With the proposed "context type" addition to VirtIO-GPU, multiple different protocols could be supported for allowing GPU communication between the guest VM and the host. Virgl could still be supported alongside other protocols like GFXSTREAM rendering commands for OpenGL or Vulkan and more rather than artificially limiting VirtIO-GPU to the Virgl use-case.

For a customer project, I recently needed to take a closer look at best strategies of deploying Chromium settings onto thrillions of client machines in a corporate network.

Unfortunately, the information on how to deploy site-wide Chromium browser policies are a little scattered over the internet and the intertwining of Chromium preferences and Chromium policies required deeper introspection.

Here, I'd like to provide the result of that research, namely a list of references that has been studied before setting up Chromium policies for the customer's proof-of-concept.

Download Google Fonts Quickly with this Neat GTK App

Filed under
Google
GNOME

Looking for an easy way to search and download fonts from Google Fonts on your Ubuntu desktop?

Try Font Downloader, a perfectly formed GTK front-end for the Google Fonts repository. The app makes it easy to browse, search, and filter (e.g., monospace, handwritten, etc) from the 1,075 free and open source fonts available on Google Fonts.

When you touch upon some typography you like the look of, Font Downloader makes it easy to test the font within the app (perfect to check it has the character coverage you need) as well download the font (to a folder of your choice) or install it on your system in ‘one-click’.

“One day I was bored of my terminal font and wanted to switch, unfortunately going through the entire process of searching Google Fonts for a font, then downloading, then copying and pasting it into my .fonts folder to only then test a font was a pain. So I decided to create this app,” the developer, Gustavo Peredo, explains on the GitHub page.

Debian 11 ‘Bullseye’ is headed to Chrome OS

Filed under
Google
Debian

I’m honestly not sure if the Linux environment on Chromebooks is actually being embraced by the masses but the fact remains that “Crostini” adds an entirely new level of productivity and capability to the Chrome operating system. In March of last year, Google updated the Linux container on Chrome OS from Debian 9 to the current Debian 10 release which is codenamed, Buster. If you have a Chromebook and you’re using Linux, this is likely the version of Debian Linux that you are leveraging. The update to Debian 10 brought a variety of features such as better kernel support, newer package versions, and a number of “under the hood” changes.

Today, I was tinkering around in the Canary Channel on an 11th Gen Tiger Lake device when I saw a new Crostini-related flag and it’s very good news for those tracking the next release of Debian Stable. Debian 11, a.k.a, Bullseye, isn’t technically slated for a full release until later this month but Google is already preparing the Chrome OS Linux container for the upgrade. The new flag will actually allow users to pick which Debian version they want to run on their devices.

[...]

I’m still testing and therefore not positive if the update is related but after upgrading to Debian 11, I was able to finally get vkcube running on Chrome OS for the first time. Luke Short and I have been fiddling with this for quite some time as full Vulkan support is one of the keys to getting Steam running natively and sufficiently on a Chromebook. My next steps will be to revert back to Buster and see if Vulkan is being leveraged by Linux and then I’ll give Steam a go and see if the Proton compatibility tool can use Vulkan. If so, Steam gaming is very, very close to being ready for prime time. Stay tuned for my results.

Hurrah, Chrome for Linux Now Supports CSD Properly

Filed under

GNOME

The latest development builds of Google Chrome fix several of the browser’s extant CSD issues on Linux desktops.

Those of you mouthing “What CSD related issues?!” at your screens (and thus me) probably run Google Chrome maximised on the desktop.

However, those of us who run the browser windowed have to endure (hyperbole) Chrome’s cranky client-side decoration support which draws a thick border around the entire window. This is highly noticeable in GTK themes with dark header bars, like Ubuntu’s Yaru.

Compare the current stable version of Google Chrome for Linux (v92 at the time of writing) against the current unstable build (v94) by dragging the divider in the image below (if you read from an RSS reader or a scraper site you won’t be able to do this because hey: the internet doesn’t work like that, honey).

  • Announcement : An AArch64 (Arm64) Darwin port is planned for GCC12

    As many of you know, Apple has now released an AArch64-based version of macOS and desktop/laptop platforms using the ‘M1’ chip to support it. This is in addition to the existing iOS mobile platforms (but shares some of their constraints). There is considerable interest in the user-base for a GCC port (starting with https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96168) - and, of great kudos to the gfortran team, one of the main drivers is folks using Fortran. Fortunately, I was able to obtain access to one of the DTKs, courtesy of the OSS folks, and using that managed to draft an initial attempt at the port last year (however, nowhere near ready for presentation in GCC11). Nevertheless (as an aside) despite being a prototype, the port is in use with many via hombrew, macports or self-builds - which has shaken out some of the fixable bugs. The work done in the prototype identified three issues that could not be coded around without work on generic parts of the compiler. I am very happy to say that two of our colleagues, Andrew Burgess and Maxim Blinov (both from embecosm) have joined me in drafting a postable version of the port and we are seeking sponsorship to finish this in the GCC12 timeframe. Maxim has a lightning talk on the GNU tools track at LPC (right after the steering committee session) that will focus on the two generic issues that we’re tackling (1 and 2 below). Here is a short summary of the issues and proposed solutions (detailed discussion of any of the parts below would better be in new threads).

  • Apple Silicon / M1 Port Planned For GCC 12 - Phoronix

    Developers are hoping for next year's GCC 12 release they will have Apple AArch64 support on Darwin in place for being able to support Apple Silicon -- initially the M1 SoC -- on macOS with GCC. LLVM/Clang has long been supporting AArch64 on macOS given that Apple leverages LLVM/Clang as part of their official Xcode toolchain as the basis for their compiler across macOS to iOS and other products. While the GNU Compiler Collection (GCC) supports AArch64 and macOS/Darwin, it hasn't supported the two of them together but there is a port in progress to change it.

  • Dirk Eddelbuettel: tidyCpp 0.0.5 on CRAN: More Protect’ion

    Another small release of the tidyCpp package arrived on CRAN overnight. The packages offers a clean C++ layer (as well as one small C++ helper class) on top of the C API for R which aims to make use of this robust (if awkward) C API a little easier and more consistent. See the vignette for motivating examples. The Protect class now uses the default methods for copy and move constructors and assignment allowing for wide use of the class. The small NumVec class now uses it for its data member.

  • QML Modules in Qt 6.2

    With Qt 6.2 there is, for the first time, a comprehensive build system API that allows you to specify a QML module as a complete, encapsulated unit. This is a significant improvement, but as the concept of QML modules was rather under-developed in Qt 5, even seasoned QML developers might now ask "What exactly is a QML module". In our previous post we have scratched the surface by introducing the CMake API used to define them. We'll take a closer look in this post.

    Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap. CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed).

  • A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board - CNX Software

    Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric. Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts.

  • What is IoT device management?

    Smart devices are everywhere around us. We carry one in our pocket, watch movies on another while a third cooks us dinner. Every day there are thousands of new devices connecting to the Internet. Research shows that by 2025, more than 150,000 IoT devices will come online every minute. With such vast numbers it is impossible to keep everything in working order just on your own. This brings the need for IoT device management. But what is IoT device management? To answer this question we first need to understand what the Internet of Things (IoT) is.
