OLPC XO C-Sound demo

This article did a good job demonstrating the versatility of OLPC XO. My preference is the C-Sound demo. I imagine the impact this hardware will cause on developing countries especially the young musicians. An orchestra that uses OLPC XO as a musical instrument is not too far from the future. Perhaps I should test it as well.

Testing Design Suite on Asus X550ZE

I recently bought an ASUS X550ZE to replace the venerable Sony VAIO N250E laptop. The reason of choosing an AMD powered laptop is for long term support i.e. the use of Vulkan API in future AMD GPU driver. In summary, here is the ASUS X550ZE specification taken from ASUS website : Processor AMD® APU A10-7400P /A8-7200P/FX-7600P Processor Chipset AMD A76M FCH Memory DDR3L 1600 MHz SDRAM, 8 GB Display 15.6" 16:9 /Full HD (1920x1080) Graphic AMD Radeon® R5 M230 + Radeon® R7 M265 DX Dual Graphics with 2GB DDR3 VRAM Built-in A10-7400P Storage 2.5" 9.5mm SATA 1TB 5400/7200 RPM Optical Drive Super-Multi DVD Card Reader 2 -in-1 card reader ( SD/ SDHC/ MMC) Camera VGA Web Camera Networking Integrated 802.11 b/g/n Built-in Bluetooth™ V4.0 (Optional) 10/100/1000/Gigabits Base T Interface 1 x COMBO audio jack 1 x VGA port/Mini D-sub 15-pin for external monitor 2 x USB 3.0 port(s) 1 x RJ45 LAN Jack for LAN insert 1 x HDMI Audio Built-in

Using AMD RX Vega driver OpenCL on Fedora 29

The Raven Ridge APU is very capable processor to handle OpenCL inside some applications like Blender, Darktable and Gimp. Unfortunately, the current implementation from Mesa, clover, stuck to 1.3, is not supported. AMD released their driver 18.40 with OpenCL2.0+ targeting only Red Hat Enterprise Linux/Cent OS 6.10 and 7.5 in addition of Ubuntu LTS. The good new is the former rpm format can be used on Fedora. The graphical part of Raven Ridge is Vega 8, basically a cut-down of Vega56 or Vega64 meaning choosing either driver for RX Vega . The instruction is provided for extracting the rpm files but here is some requirements for OpenCL: kernel-devel (provided by Fedora repository) amdgpu-dkms dkms libopencl-amdgpu-pro opencl-amdgpu-pro-icd Once done, applications needing OpenCL will automatically detect the driver located on /opt/amdgpu/lib64 . Blender will list as unknown AMD GPU and Darktable will enable it. OpenCL from official AMD driver enabled on Darktable Ra
