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.
“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.”
KeyCoin is today’s Random Coin of the Day for its extensive development, including a full on customized version of TailsOS, the Linux distribution where Tor protects all communication. The team also has trading tools and an encrypted messaging system in the works along with a few other amazing features.
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.
Oracle Solaris, one of the most widely deployed UNIX operating systems, which delivers critical cloud infrastructure with built-in virtualization, simplified software lifecycle management, cloud scale data management, and advanced protection for public, private, and hybrid cloud environments, has finally reached version 11.2.
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.
