Detecting CPU steal time in guest virtual machines

opensource.com - Wed, 01/08/2020 - 16:01

CPU steal time is defined in the GNU top command as "time stolen from [a] VM by the hypervisor." CPU steal time occurs when a hypervisor process and a guest instance are trying to utilize the same hypervisor physical core (pCPU) at the same time. This results in less processor time available to the guest's virtual CPU (vCPU) and performance degradation for the guest.

Millions of readers: How to be a part of our 2020 journey

opensource.com - Wed, 01/08/2020 - 16:00

Welcome to 2020 at Opensource.com!

Last month, on December 31, 2019, while our editorial team had settled down for a long winter's nap—no, truthfully we were simply taking a well-deserved break—Opensource.com hit a record with 2.1 million reads and 1.3 million unique visitors.

That kind of growth shows that people—a lot of them—are looking for help in figuring out how to choose and use open source. And our intention is for our community to be the place that continues to help them contribute. Here's what that will look like in 2020.

GCC 10 Link-Time Optimization Benchmarks On AMD Threadripper

Phoronix - Wed, 01/08/2020 - 04:08
Stemming from the recent news in Fedora 32 potentially LTO'ing packages by default for better performance and not yet having checked on the Link-Time Optimization performance of the in-development GCC 10, here is a fresh look at the possible performance gains from making use of link-time optimizations for generating faster binaries. This round of testing was done on the AMD Ryzen Threadripper 3960X and is complementary to the recent Profile Guided Optimization benchmarks.

Subaru Adopts AGL Software for Infotainment on New 2020 Subaru Outback and Subaru Legacy

The Linux Foundation - Wed, 01/08/2020 - 01:00

LAS VEGAS – CES 2020, January 7, 2020Automotive Grade Linux (AGL), a cross-industry effort developing an open source platform for all connected car technologies, today announced that the Subaru Starlink infotainment platform on the all-new 2020 Subaru Outback and the 2020 Subaru Legacy uses open source software from the AGL Unified Code Base (UCB) platform.

“Using AGL’s open source software allows us to easily customize the user experience and integrate new features, creating an integrated cockpit entertainment system that is more enjoyable for drivers,” said Mr. Naoyoshi Morita, General Manager of Electronic Product Design Dept. of Subaru Corporation. “We believe that shared software development through Automotive Grade Linux benefits the entire industry, and we look forward to our continued involvement and collaboration with other automakers and suppliers.”

AGL is supported by more than 150 members, including 11 automakers, who are working together to develop the AGL Unified Code Base (UCB) platform, a shared software platform that can serve as the de facto industry standard for infotainment, telematics, and instrument cluster applications. Sharing an open platform allows for code reuse and a more efficient development process as developers and suppliers can build once and have a product work for multiple automakers.

“Subaru has been an AGL member for many years, and we are very excited to see them use AGL in production,” said Dan Cauchy, Executive Director of Automotive Grade Linux. “The AGL platform continues to gain traction, and we expect to see more automakers using it in production in the years to come.”

AGL BOOTH AT CES 2020
The AGL booth at CES 2020 in the Westgate Hotel Pavilion, booth 1815, features 19+ demos by AGL members showing infotainment, instrument cluster, autonomous driving, security, connectivity, and other applications running on the AGL open source software platform.

The AGL booth will be open to the public during CES show hours and during the AGL Evening Reception & Demo Showcase on Wednesday, January 8, from 6:00 – 8:00 pm PT. Additional details and registration for the Evening Reception are available here.

Media and analysts are also invited to attend an AGL Media Happy Hour at CES on Tuesday, January 7, from 3:00 – 5:00 pm PT in the AGL booth. Please RSVP here.

About Automotive Grade Linux (AGL)
Automotive Grade Linux is a collaborative open source project that is bringing together automakers, suppliers and technology companies to accelerate the development and adoption of a fully open software stack for the connected car. With Linux at its core, AGL is developing an open platform from the ground up that can serve as the de facto industry standard to enable rapid development of new features and technologies. Although initially focused on In-Vehicle-Infotainment (IVI), AGL is the only organization planning to address all software in the vehicle, including instrument cluster, heads up display, telematics, advanced driver assistance systems (ADAS) and autonomous driving. The AGL platform is available to all, and anyone can participate in its development. Learn more: https://www.automotivelinux.org/

Automotive Grade Linux is a Collaborative Project at The Linux Foundation. Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems. www.linuxfoundation.org
