Filed under

Hardware

While the Raspberry Pi has always been cheap, the Foundation didn’t rest on their laurels with the Model A+ price. In fact, Google’s Eric Schmidt had a hand in making it cheaper…
While it would have been the easiest thing in the world to continue selling the Raspberry Pi at the same price, the charitable foundation behind the credit card-sized PC made it even cheaper with the recent release of the Model A+. Why did they abandon their already impressive $25 price? Eben Upton explains:

AMD's HSA Run-Time Library Is Now Open-Source

Filed under
Hardware
OSS

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.

Still running 32 bit Ubuntu?

Hardware
Ubuntu

I’m considering a proposal to have 16.04 LTS be the last release of Ubuntu with 32 bit images to run on 32 bit only machines (on x86 aka Intel/AMD only – this has no bearing on ARM). You would still be able to run 32 bit applications on 64 bit Ubuntu.

Nouveau-PerfKit Still Being Worked On, Perf Counter Code Expected For Linux 3.20

Filed under
Linux
Hardware

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.
