  • Planet Computers' clamshell phone can dual-boot Android and Linux

    Planet Computers' laptop-like Cosmo Communicator phone just became that much more useful to its audience of very particular power users. The Cosmo now supports a promised multi-boot function, letting you run Android (both regular and rooted), Debian Linux and TWRP on the same device without one replacing the other. You'll have to partition your storage and know your way around a boot menu, but this will give you a way to run Linux apps or otherwise experiment with your phone.

    You won't lose over-the-air updates for Android by installing Linux, Planet Computers said.

    The multi-boot firmware is available for free, and there are instructions for installing Debian and other software. This still isn't for the faint-hearted. However, it also represents one of the few instances where a phone maker has officially enabled support for operating systems besides the one that ships with the device. The Cosmo is also fairly well-suited to Linux thanks to its keyboard -- you won't have to jump through hoops to use the command line.

  • How can IT manage Android Things devices in the enterprise?

    Recent versions of Google's Android OS support a wider range of devices via the Android Things program's APIs and managing some of the newer devices can seem complicated at first.

    Thankfully, the underlying OS is essentially the same on all Android devices, so the EMM platform management and enrollment processes are usually similar for Android Things devices. The challenge for mobile admins is to develop a version of Android -- using the Android SDK and Android Things APIs -- that functions on these dedicated devices.

Cosmo Communicator clamshell smartphone gets dual-boot

  • Cosmo Communicator clamshell smartphone gets dual-boot functionality

    Smartphones have evolved to the point where we are basically carrying a reasonably capable miniaturized PC in our pockets. However, mobile operating systems are limited and unable to run desktop apps.
    Planet Computers is changing the typical paradigm of a closed mobile-OS ecosystem. On Monday, it released a firmware update to its £665.83 ($860) Cosmo Communicator that allows users to install regular or rooted Debian Linux side-by-side with Android. The company had promised this feature was coming when it launched the stylish foldable in December 2018.

Linux now joins Android on Planet's little Cosmo Communicator

  • Linux now joins Android on Planet's little Cosmo Communicator computer-phone

    The Cosmo Communicator was promoted as being able to run Linux and Android but until now it didn't have dual-OS functionality, leaving Android as the default OS and no option to switch to Linux.

    The company has now announced that the Cosmo Communicator can run Debian Linux with KDE, which offers a full graphical interface.

    [...]

    The addition of Linux and KDE allows users to run more applications. Planet Computers highlights that devices that have been partitioned for dual-OS support can still receive over-the-air Android firmware updates.

    Planet Computers has provided instructions and links for downloading the firmware on its support pages.

    "Offering a viable alternative operating system on the Cosmo Communicator has been a cornerstone of all Planet devices. The Linux community has been instrumental in the firmware development and together we will continue to refine and enhance the Linux user experience," said Dr Janko Mrsic-Flogel, CEO of Planet Computers.

Cosmo Communicator Android PDA can now run Linux side-by-side

  • Cosmo Communicator Android PDA can now run Linux side-by-side

    There has been a recent uptick in interest in Linux-based smartphones but the newest breed of such devices is targeted at early testers and developers. For those who simply want a usable and polished Linux mobile device, the choices are extremely slim. A few years ago, Planet Computers launched two communicator-style Android PDAs that promised to support other operating systems, including Linux. Now the UK-based company is making good on that and is releasing multi-boot support for Linux as well as a rooted Android image.

    The Cosmo Communicator and its Gemini PDA predecessor are on a league of their own when it comes to mobile devices. Inspired by the old Psion handheld computers, these smartphones resembled miniature laptops like the “communicators” of yesteryears. More than just a nostalgia trip, however, Planet Computers promised a more open mobile experience as far as operating systems go and it has finally gotten the ball rolling for the 2019 Cosmo Communicator.

    The company just announced that they now support booting multiple operating systems in part thanks to the new TWRP support. It provides instructions on how to install Debian GNU/Linux running the popular KDE Plasma Desktop onto a separate partition. There are also instructions on doing the same for a rooted version of Android so that the main Android version remains untouched.

Router Freedom challenged by new European rules

From 21 June a new set of rules will guide the implementation of Router Freedom in Europe. The internalisation of the rules by the 27 EU member states will face challenges with negative consequences for Router Freedom. The FSFE contributed to several improvements of the guidelines and will monitor compliance with them. The COVID-19 pandemic shows how dependent people are on the Internet for their work and personal life. In times of lockdown, when people need to stay home and work remotely, the whole internet traffic, encryption, business and work interaction are transferred through personal routers. Since 2013, the FSFE has been advocating for Router Freedom in Europe with outstanding results in Germany and effects beyond its borders. Now, a new set of rules, for which the FSFE contributed to improve, will guide the implementation of Router Freedom in Europe. We summarise the positive outcomes as well as the challenges ahead.

Features Merged Into Linux 5.8 Tree

  • Linux 5.8 Flipping On ERASE/Discard/TRIM For All MMC Hosts

    The MMC changes for new kernel cycles don't tend to be particularly noteworthy but it's a different story with the new Linux 5.8 kernel cycle. With Linux 5.8, erase/discard/trim support is being enabled now for all (e)MMC/SD hosts. The Linux kernel has long supported this discard/trim support for MMC/SD but until now it's been opt-in by the host drivers. But thanks to all of the host driver work and MMC core improvements over the past number of kernel cycles, the developers are content enough with the overall state of the support that they are no longer making it opt-in but will make it supported on all hosts. Of course, the card in question still needs to support these commands for it to be supported, but at least the host capability checks are now removed from MMC core.

  • Linux's Pstore Picking Up A Block Device Backend For Storing Oops & Panic Messages

    Linux's pstore "persistent storage" code is seeing a number of improvements for the Linux 5.8 kernel. Pstore is the Linux interface to persistent storage for archiving a limited amount of data across reboots, such as for archiving kernel oops or panic messages so they can be easily analyzed following a reboot from such a fatal problem.

  • AMD SPI Driver Sent In For Linux 5.8

    Adding to the multiple new AMD drivers coming with Linux 5.8 is their new SPI controller driver. The AMD SPI controller driver (spi-amd) was mailed out in April and for supporting the SPI controller within newer AMD SoCs. This 300+ lines of code driver was previously outlined in this earlier article.

  • AMD Energy Driver Sent In For Linux 5.8 Along With Driver For Industrial/Military SBCs

    The hardware monitoring "HWMON" subsystem updates were sent in today for the newly-opened Linux 5.8 merge window. On the hardware monitoring front this cycle the updates include: - The new AMD Energy driver for exposing the energy sensors on Zen/Zen2 CPUs. From my own testing so far this new driver is working out quite well albeit long overdue.

AMD Ryzen 5 4500U Benchmarks - Previously Unimaginable Performance For Sub-$600 Laptops

A few weeks back I began delivering Ryzen 7 4700U Linux laptop benchmarks for this 8-core Zen 2 mobile CPU with Vega graphics. The results have been very good and the support is in good shape with the latest Linux kernel, but many have been wondering about the Ryzen 5 4500U. The Ryzen 5 4500U is beginning to appear in several $500~600 USD laptops and offers six cores. Here are benchmarks and initial impressions with the Lenovo Flex 5 that features a 14-inch 1080p display, 16GB dual channel memory, 256GB SSD, and the Ryzen 5 4500U all for just $599! Given the overwhelming interest by readers in the Ryzen 5 4500U in it appearing in several budget-friendly laptops, curiosity got the best of me for testing this laptop as well as with there not being many (Windows) benchmarks in general for the 4500U at this point. As usual with most laptop vendors not being interested in laptop coverage, I ended up buying the laptop last week as a fun testing candidate given Phoronix turning 16 years old this week - a birthday of benchmarking! The most interesting value laptop I've found with the Ryzen 5 4500U has been the Lenovo Flex 5 15-inch 2-in-1 that has the Ryzen 5 4500U with a 1080p display, 2 x 8GB DDR4-3200 memory, Vega graphics, and a 256GB NVMe SSD all for just $599. The particular SKU is 81X20005US for those looking for a sub-$600 laptop. Read more
