Wind River Linux 4 is Wind River's fourth-generation commercial embedded Linux platform. Linux 4 is based on the recently released Linux 2.6.34+ kernel, cross-compiling toolchains GCC 4.4, EGLIBC 2.11, and GDB 7. The new platform supports ARM, Intel, MIPS, and Power architectures. Wind River Linux 4 is on track for compliancy with forthcoming Carrier Grade Linux (CGL) 5.0 standards for high availability and serviceability and Linux Standard Base (LSB) 4.0 certification requirements for application portability.
Key features and benefits
Multiple options for virtualization strategies to leverage the power of multi-core hardware, from KVM paravirtualized device drivers in the kernel to Wind River Hypervisor Support for a fully pre-emptible kernel (PREEMPT RT) and a seamless migration path for teams currently developing products on Wind River Linux 3.x
User space, workflow and tool enhancements to increase productivity and facilitate resource sharing across multiple teams, including a new source management control solution, an improved mechanism for capturing, archiving and sharing patches, analysis tools for memory, footprint and power usage, and new tools to speed cross-compiling and debugging
Board support packages for next generation multiprocessors from Cavium Networks, Freescale, Intel, NetLogic Microsystems, and Texas Instruments, enabling customers to develop future platform deployments in networking, industrial and medical, aerospace and defense, and consumer device markets
Capability for customers to build applications in a native build environment on x86-based machines and reduce customer development and diagnosis time on x86-based platforms
“We’re providing customers with the latest Linux technology in a stable, tested and integrated development environment,” said Paul Anderson, vice president of marketing and strategy for Linux products at Wind River. “Having a fully supported, development-ready Linux platform enables customers to reduce cost and time-to-market by focusing resources on product differentiation and revenue-impacting activities, rather than spending time reinventing base technologies or dealing with potential open source license issues.”
Based on customer requests to create a resource of active and accessible experts, Wind River introduced the Wind River Developer Community for Linux in August. This community encourages interactions between Wind River users, Wind River engineers and embedded Linux community experts and provides a platform for exchanging ideas, news, technical knowledge, best practices and tips to help customers maximize their use of Wind River Linux and embedded Linux.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
