Last week we reported on AMD's plans for a complete user-space open-source HSA stack. Today they have finally delivered!
The last remaining component,. the HSA run-time library was open-sourced this afternoon on GitHub. This HSA library goes with the AMD GPU LLVM back-end to form a complete user-space open-source driver stack for HSA applications using kernels written using OpenCL C99. This code goes along with AMD's new "AMDKFD" kernel HSA driver that's still in the process of being mainlined. The AMDKFD driver could potentially appear in the Linux 3.19 kernel but probably won't be merged before Linux 3.20 if going through the DRM subsystem pull.
Open-source computers have so far lacked good graphics, but Gizmosphere’s new Gizmo 2 is an exception.
The Gizmo 2 is an uncased single-board computer that will sell for US$199. The computer can be used to build robots, electronics with large screens, or interactive computer systems that can recognize gestures or images.
Disk images are computer files of a disk volume or an entire data storage device, such as a hard drive, optical disk (e.g. DVD, CD, Blu-ray), tape drive, USB flash drive, or floppy disk. A disk image represents the content exactly as it is on the original storage device, including both data and structure information.
The main differences between the B+ and the Raspberry Pi model B are the new model has:
four USB ports (versus two in the model B )
a microSD card (versus a full size SD card in model B )
a video jack integrated with the audio jack (versus two separate jacks in the model B )
GPIO pins extended to 40 pins (versus 26 pins in the model B )
lower power consumption
four mounting holes
What has not changed:
The price, it is $35 USD
The amount of RAM, it has 512 Mb
Announced over the summer when AMD was celebrating their 30 years of graphics celebration was the Radeon R9 285, a $250 graphics card built on the company's latest GCN graphics processor technology to replace the Radeon R9 280. We finally have our hands on a Radeon R9 285 "Tonga" for delivering the first look at its Linux performance.
Samuel Pitoiset has been working hard to reverse-engineer NVIDIA's hardware performance counters of their GPU and to allow them to be taken to their full potential under the open-source Nouveau Linux graphics driver.
For over one year the student developer Samuel Pitoiset has tasked himself with reverse engineering NVIDIA's GPU performance counters with an end goal of coming up with an NVPerfKit-like implementation for Linux that runs off the reverse-engineered Nouveau stack. Samuel has been involved with Google's Summer of Code and has stuck around doing great work for the limited-staffed Nouveau driver.
Recently, as part of the anti-women #GamerGate campaign, a set of awful humans convinced Intel to terminate an advertising campaign because the site hosting the campaign had dared to suggest that the sexism present throughout the gaming industry might be a problem. Despite being awful humans, it is absolutely their right to request that a company choose to spend its money in a different way. And despite it being a dreadful decision, Intel is obviously entitled to spend their money as they wish. But I'm also free to spend my unpaid spare time as I wish, and I no longer wish to spend it doing unpaid work to enable an abhorrently-behaving company to sell more hardware. I won't be working on any Intel-specific bugs. I won't be reverse engineering any Intel-based features. If the backlight on your laptop with an Intel GPU doesn't work, the number of fucks I'll be giving will fail to register on even the most sensitive measuring device.
