open source powerpc laptop

Since IBM open sourced its PowerPC processors (see Newsdesk, LXF255) there’s been more interest in trying to create open source PowerPC systems, such as the Raptor Talos II. An alternative project that was started back in 2017 (by Power Progress Community, www.powerprogress.org) is attempting to build a complete open source designed laptop, based on the NXP T2080 PowerPC processor. Previous funding campaigns have successfully delivered a PCB design. The current phase of funding will deliver bus simulations of the PCB design. Further goals will include delivering prototypes, full hardware testing and certifications. A Spanish company called Slimbook is set to provide the body of the Eclipse laptop. The body of the laptop is actually the entire case, the cooling system, the screen, the keyboard, the backlight, the webcam, the speakers and the…

ongoing development

Greentime Hu, senior manager at Andes Technology, posted version seven of a patch series, adding support for the vector ISA extension to RISC-V. The patch series is based upon version 0.9+ of the hardware spec, meaning that it could still change before being finalised. Shakeel Butt (Google) posted a thread titled “Machine lockups on extreme memory pressure” in which a heavily loaded server with thousands of active network connections would occasionally wedge hard and fail even to properly run the OOM (Out Of Memory) killer. It led to interesting discussions.…

a quick reference to… terminal history

The command line provides an efficient way to get things done, You can use the cursor up key to revisit the previous commands you entered, but the shell offers so much more. Bash, along with other shells, maintains a history file of the last 500 or so commands you typed. The exact number is determined by the HISTFILESIZE and HISTSIZE environment variables. We generally set these to 1,000, but you don’t want to be hitting the up key hundreds of times to find the invocation of a command you used last week, so press Ctrl-R instead. This starts the history search. Start typing part of a command and it’ll show the most recent match. As you type more the match improves. If you want an earlier match, press Ctrl-R again. Once…

get help now!

We’d love to try and answer any questions you send to lxf.answers@futurenet.com, no matter what the level. We’ve all been stuck before, so don’t be shy. However, we’re only human (although many suspect Jonni is a phantasm), so it’s important that you include as much information as you can. If something works on one distro but not another, then tell us. If you get an error message, please tell us the exact message and precisely what you did to invoke it. If you have, or suspect, a hardware problem, let us know about the hardware. Consider installing hardinfo or lshw. These programs list the hardware on your machine, so send us their output. If you’re unwilling, or unable, to install these, run the following commands in a root terminal and send…

nvidia geforce now

We weren’t hugely impressed with Google’s Stadia game streaming service, so when Nvidia announced its GeForce NOW stream service would support Chrome OS and offer an hour-long session a day for free, we had to take a look. Unlike Google Stadia the Nvidia GeForce NOW service piggy-backs on your existing gaming accounts – largely Steam, Epic and Ubisoft’s UPlay along with some online offerings such as World of Tanks. It doesn’t provide any games in itself; you must already own any it supports via a supported gaming service. It’s a bit confusing at first and that’s played out when you launch a game; it has to standup a “gaming rig” and (mostly with Steam) you see the Steam interface from where you log in, “install” the game (this is instant) and run…

how we tested…

Most modern desktop distributions such as Ubuntu, Linux Mint and Mandriva are anathema to power users. This is because these distributions aim to provide a ready-to-use environment to users without much intervention or interaction on their part. While this is certainly appreciable, especially for novice users, experienced campaigners might prefer more control over their Linux distribution. We’ll test the distributions on all the usual criteria such as documentation, installation, bundled applications and even package management. That’s because while power users might well be able to resolve dependencies manually, it’s neither smart nor efficient to do so. We’ll also discuss the ideal use case for these distributions and their longevity, which is reflected by the release policy, frequency of updates and stability. On top of all that, we’re looking for a distribution that…
