Samuel Pitoiset continues making steady, great progress on his Google Summer of Code project as a student developer reverse-engineering and implementing NVIDIA hardware performance counters within the open-source Nouveau driver.
For months now he's had a solid understanding of how NVIDIA's performance counters operate and has been working towards exposing them in a NVPerfKit-like open-source manner and exposing them to OpenGL developers. Samuel's latest update revealed his MP counter work was up to a prototype stage while today he has a new blog post concerning the approaches to exposing the performance counters in Nouveau.
Several new ARM devices will be supported by the in-development Linux 3.17 kernel while some less-than-optimally-supported ARM hardware is also getting stripped from the mainline kernel tree.
Olof Johansson emailed in the large batch of ARM changes today for the Linux 3.17 merge window. Some highlights for the pull request consisting of around 750 patches include.
UniPi is seeking Indiegogo funding for a Raspberry Pi add-on for building automation with analog and digital I/O, changeover relays, and 1-Wire interfaces.
The Raspberry Pi has found its way into many a home automation project, from lighting controls to automatic sprinkler systems, and is often used as a prototype for commercial systems. But is the modest RPi up for managing an entire building? No problem, says Czech startup UniPi, which is offering Indiegogo funding packages of 99 Euros ($133) and 109 Euros ($146) for its UniPi building automation add-on board.
The input subsystem pull request has been submitted for the Linux 3.17 merge window.
Among the items in the input pull sent in by Dmitry Torokhov is a rework of the Wacom driver, which now has been converted to the kernel's HID infrastructure and the USB/Bluetooth support has been unified where as previously Wacom was just treated as a USB driver. This big Wacom driver update was done by Benjamin Tissoires. In the Wacom space, there's also now a driver for serial Wacom devices.
Our brand new sister magazine RasPi is here! Issue #1 is out today, available to download through Apple’s App Store. It’s jam-packed full of amazing content and only costs 69p/99¢.
Each month we’ll be walking you through a big Pi project, showing off some of the best work in the community, sharing your tweets, letters and emails, and of course giving you a whole bunch of tutorials to teach you how to get the most from your Raspberry Pi and make amazing things with it.
Takashi Iwai of SUSE has sent in his set of sound/ALSA changes that are queued up for the Linux 3.17 kernel.
The sound subsystem updates for Linux 3.17 are mostly centered around a ton of ASoC updates, but there's also a few noteworthy changes to the commonly used HD Audio code. In particular, upcoming Intel Braswell hardware has its audio supported by the Linux 3.17 kernel. Going along with Braswell as HD Audio changes are fix-ups for several HD-Audio-using systems including the HP Envy TS, Dell XPS 15, and Gigabyte BXBT-2807, among other platforms.
With the Fedora 21 Alpha freeze looming in the rear view mirror, although the object wasn’t as close as it would appear, I thought it was high time that I gave a brief overview of the state of ARM aarch64 in Fedora. Some might assume the silence means not a lot has been happening but this is extremely far from the truth!
Itus Networks is set to launch a $149 “iGuardian” network security appliance on Kickstarter that runs OpenWRT Linux and the Snort IPS stack on a MIPS64 SoC.
Few vendors have targeted the consumer network security appliance market, and even fewer have done so with pricing under $500. A San Jose, Calif.-based startup called Itus Networks, however, plans to protect your home WiFi router with a $149, open source Linux iGuardian device that offers both a network intrusion prevention system (NIPS) and a network intrusion detection system (NIDS). The device blocks cyber attacks while also filtering out malware “and other undesirable content,” says the company. Like other network security appliances, it sits between your Internet source and your WiFi router, acting as a security firewall.
[Updated 12:00PM] — Marvell has posted detailed datasheets on its previously opaque Armada 370 and XP SoCs, used in Linux-based NAS systems from Buffalo, Netgear, and Synology.
Until now, datasheets and other details about the ARM-based Armada 370 and Armada XP system-on-chips have been available only under NDA to Marvell customers and partners. During the past month, however, the chipmaker released detailed datasheets on the SoCs, with no restriction or registration required. Both functional and hardware spec datasheets were released, each of which is more like a manual than a typical datasheet.
We were tipped to the Marvell Armada 370 and XP datasheet releases by embedded Linux development and training specialist Free Electrons. (The company is well known here for its regular contributions of videos and slide decks from shows like the Embedded Linux Conference, released under a Creative Commons license.)
