Kernel Developers Begin Work On CPPC Processor Performance Controls

Filed under
OS

Ashwin Chaugule of Linaro has announced his experimental kernel implementation of Collaborative Processor Performance Controls (CPPC) that is part of the ACPI 5.1 specification.

An increasing amount of x86 and ARM64 hardware is expected in the marketplace soon that supports CPPC, which is a new interface for CPU performance control between the OS and platform, while right now it's just exposed by a limited number of systems. Here's more from Ashwin's description:
CPPC is the new interface for CPU performance control between the OS and the platform defined in ACPI 5.0+. The interface is built on an abstract representation of CPU performance rather than raw frequency.

elementary OS Freya Beta Is Out, Still the Most Beautiful OS in the World

Filed under
OS

“Freya inherits core components from Ubuntu 14.04.1 LTS such as the Linux kernel (version 3.13), hardware drivers, and graphics stack. This includes support for EFI stub-loading, which is a kernel feature that enables booting directly from (U)EFI, without the need for an additional bootloader such as GRUB. Ubiquity does not yet have support for this configuration, but one of our developers has created a guide for a GRUB-free install of Freya on modern Mac computers using rEFInd.”

Peppermint OS 5: Light, Refreshing Linux

Linux

Using the Ice technology in the Peppermint OS is much like launching an app on an Android phone or tablet. For example, I can launch Google Docs, Gmail, Twitter, Yahoo Mail, YouTube, Pandora or Facebook as if they were self-contained apps on a mobile device -- but these pseudo apps never need updating. Ice easily creates a menu entry to launch any website or application as if it were installed.

My First Unikernel

Filed under
OS

Unikernels promise some interesting benefits. The Ubuntu 14.04 amd64-disk1.img cloud image is 243 MB unconfigured, while the unikernel ended up at just 5.2 MB (running the queue service). Ubuntu runs a large amount of C code in security-critical places, while the unikernel is almost entirely type-safe OCaml. And besides, trying new things is fun.

Emacs & the obsessive email mongerer

I had already mentioned in passing here that I am using Emacs for a variety of tasks: outline, project management and planning with Org-Mode, IRC (go figure, my default email client on all my machines is Emacs’ ERC), notes editing or quick scribbling with the Scartch buffer (happens to me all day long), and regularly, albeit less frequently than in 2013, various editing of html pages, javascript and sometimes even Python when I dare to edit one or two things in Python scripts. A consequence of all these use cases is that I have Emacs open almost everyday on almost any of my machines. Read more

MIPS tempts hackers with Raspbery Pi-like dev board

Hard to choose between Raspberry Pi, BeagleBone Black, and MinnowBoard Max? Now there’s another choice: the open source MIPS-based “Creator CI20″ dev board. In a bid to harness some of the energy and enthusiasm swirling around today’s open, hackable single board computers Imagination Technologies, licensor of the MIPS ISA, has unveiled the ISA’s counter to ARM’s popular Raspberry Pi and BeagleBone Black SBCs. These days, every processor vendor simply must have a community supported dev board in order to engage with the developer communities. (Incidentally, Intel’s is the MinnowBoard Max and AMD’s is the Gizmo.) Read more

Samsung announces the Gear S while LG officially unveils the G Watch R

Samsung announced yet another smartwatch, Samsung Gear S that runs Tizen and comes with a 3G wireless radio. I have seen some call this the Gear Note because it does have a long two inch curved Super AMOLED display. The Gear S has WiFi, Bluetooth, and 3G radios and antennas inside so you can use the watch when your phone isn't handy. Turn-by-turn pedestrian navigation is powered by HERE. It has an integrated GPS chip and can be used for exercise, again without a phone connection. Read more
