Linux on ARM
Wind River has expanded the hardware support in its embedded Linux for the latest ARM, Intel, MIPS, and Power architectures as well as updating the kernel, toolchain, and user space for the latest Yocto Project release.
The ODROID-XU is the latest exciting ARM development board. Rather than aiming for low-cost like the Raspberry Pi, the ODROID-XU currently offers maximum performance when it comes to open ARM development boards.
When the first ARM Cortex-A15 SoCs started rolling out in devices I found the dual-core A15 performance to be crazy fast for ARM and still find the Cortex-A15 performance to be great for low-power devices. Now, however, there's quad-core Cortex-A15 SoCs and even with the big.LITTLE architecture these four A15 cores can be paired with four A7 cores. In this article are our first benchmark results to share of a Samsung Exynos 5 Octa with a 1.6GHz Cortex-A15 configuration paired with a quad-core Cortex-A7 processor.
ISEE announced a highly compact single board computer powered by a 2GHz dual-core Cortex-A15 based Texas Instruments OMAP5432 system-on-chip. The IGEPv5 SBC ships with a Yocto-built Linux stack, but also supports Android, and is packed with I/O including five USB ports, mSATA, microSD, HDMI, DisplayPort, audio in/out, gigabit Ethernet, WiFi and Bluetooth wireless, and more.
The LLVM compiler infrastructure has now received support for the Cortex-A57, ARM's highest-end 64-bit AArch64 processor.
We all love to root for an underdog, especially in tech, where revolutions have so often been launched from garages or dorm rooms. But the past few years, there's been little room for Cinderella stories in the world of tablets and mobile computing as massive monoliths like Apple, Google, and Samsung have come to dominate, and even well-established names like Microsoft and BlackBerry struggle to gain a foothold.
ARM and other Linux stakeholders are still working to bring power-aware scheduling to the kernel.
PicUntu is a custom version of Ubuntu Linux designed to run on TV boxes and other devices with Rockchip’s ARM-based processors. Now it’s easier to install than ever, offering a way to turn a cheap Android TV box into a full-fledged Linux computer.
Back in 2010, I wrote two articles about a SystemC model used to load the Linux kernel and its various artifacts into memory for ARM virtual platforms. The first was A SystemC TLM 2.0 ARM Linux Boot Loader and the second was More on the SystemC ARM Linux Boot Loader. At the time I covered the kernel, Linux kernel command line, and RAM-based file system.
For months now there's been an Armada DRM/KMS graphics driver for Marvell Armada ARM SoCs. Having gone through several patch revisions, it appears that all major issues have now been addressed for this nearly 5,000 line open-source driver.
