The community of open source mobile developers around the world are a vocal bunch – and here at Broadcom we’ve heard their call.
To date, there’s been a dearth of documentation and vendor-developed open source drivers for the graphics subsystems of mobile systems-on-a-chip (SoC). Binary drivers prevent users from fixing bugs or otherwise improving the graphics stack, and complicate the task of porting new operating systems to a device without vendor assistance.
But that’s changing, and Broadcom is taking up the cause.
That "blob" is the closed source driver code that the Pi requires today. "In common with every other mobile graphics core, using the VideoCore IV 3D graphics core on the Pi requires a block of closed-source binary driver code (a 'blob') which talks to the hardware," Upton wrote. "Our existing open-source graphics drivers are a thin shim running on the ARM11, which talks to that blob via a communication driver in the Linux kernel. The lack of true open-source graphics drivers and documentation is widely acknowledged to be a significant problem for Linux on ARM, as it prevents users from fixing driver bugs, adding features and generally understanding what their hardware is doing."
Newark Element14′s $79, Linux-ready “SAMA5D3 Xplained” SBC showcases Atmel’s SAMA5D3 processor, with features like dual LAN ports and Arduino compatibility.
The folks at UK-based Cloudsto have added a new device to their range of small, ARM-based Linux computers.
The Rikomagic MK902 LE is a small box with a Rockchip quad-core processor, 2GB of RAM, and up to 16GB of storage. It ships with Ubuntu Linux, and it’s available from the Cloudsto shop for £94.99 and up, or about $159.
Back on Tuesday I delivered a launch-day review of the NVIDIA GeForce GTX 750 Ti on Linux. This first graphics card built on NVIDIA's new Maxwell architecture has been running fantastic under Linux for being a mid-range graphics card. The GM107 GPU core found on the GTX 750 Ti is incredibly power efficient, as was shown in numerous articles on launch-day. For those curious more about the GeForce GTX 750 Ti Linux performance, here are some more OpenCL and OpenGL performance results.
AS you may know, just few weeks ago OSHWA published the results from 2013 Open Hardware Community survey. You can find original datasheets and everything here. Despite raw data is good, I thought it was good to spend some time looking at the data trying to gather more insights, when possible, still keeping in mind that the survey samples a very limited and polarized (OSHWA centric) chunk of the community. But we need to start from something in a way.
The first is the Hachiko development board for the Renesas RZ/A microcontroller, which is an ARM Cortex-A9-based MCU. This is positioned as a low end design board for applications such as door entry phones, barcode scanners and data communication modules.
Users can save captures for offline analysis, share them with other PicoScope for Windows and PicoScope for Linux users, or export them in text, CSV and Mathworks MATLAB 4 formats. The only additional hardware needed is a USB oscilloscope.
Planet unveiled a Linux-based, 16-channel network video recorder called the NVR-1620, with dual HDD bays, dual displays, and up to 2560 x 1920 resolution.
Taiwan-based Planet has a long track record of making networking and surveillance appliances. Its latest NVR-1620 network video recorder supports 16 IP video channels, and up to 16 devices can be networked for 256 total channels accessible via a central monitoring site. In addition, most mobile platforms, including Android, are supported for remote viewing.
