Kernel Log: updated Radeon drivers, mdadm and ALSA

Filed under
Linux

AMD’s kernel and X.org developer Alex Deucher has published version 6.14.0 of driver package xf86-video-ati. It contains the X.org driver for Radeon graphics hardware, which provides much better support for the latest version of Radeon graphics chips. For example, it now not only controls the graphics kernel of the Fusion processors developed under codename "Ontario", but also the Northern Islands GPUs based on Radeon HD models 62xx to 68xx. With both of them, 2D acceleration via EXA now works, as does video acceleration with the antiquated Xv (Xvideo), but in both cases the driver remains dependant on Linux kernel 2.6.38, which is still under development and is expected to be released at the end of March or beginning of April. Its DRM driver with functions for KMS (kernel-based mode-setting) is required anyway for Northern Islands GPUs because the driver does not support UMS (user mode-setting) on these chips.

In combination with KMS in kernel 2.6.36 and later, the driver also supports EXA and Xv on Evergreen GPUs on Radeon HD 5,000 series models. The developers have considerably upgraded the man page in the new version. Along with kernel 2.6.38, the driver offers page-flipping support so that image updates are more precisely synchronised with the start of frame re-draw. For further information on this new technology in Linux 2.6.38, see the first part of the series "Coming in 2.6.38".

World’s smallest i.MX6 module has onboard WiFi, eMMC

Variscite unveiled a 50 x 20mm “DART-MX6″ module that runs Linux or Android on the Freescale i.MX6, with up to 64GB eMMC flash and -40 to 85°C support. Variscite’s claim that the 50 x 20mm DART-MX6 is the world’s smallest computer-on-module based on Freescale’s i.MX6 system-on-chip appears to be a valid one. It beats the smallest ones we’ve seen to date: TechNexion’s 40 x 36mm PICO-IMX6, and Solid-Run’s 47 x 30mm microSOM i4. It’s also just a hair larger than Variscite’s own 52 x 17mm DART-4460, which is based on a dual-core TI OMAP4460 SoC, and Gumstix’s slightly larger 58 x 17mm Overo modules, which use TI Sitara AM37xx SoCs.

BQ Aquaris E4.5 Ubuntu Edition review

The BQ Aquaris e4.5 Ubuntu Edition is not the debut Canonical must have envisaged for Ubuntu Phone, in the early days of the platform’s development. It’s a perfectly functional smartphone for the most part, and we like the concept of scopes, but the hardware is humdrum, performance is sluggish, and the software running on it is rough and ready, and full of holes. We’ll be tracking the progress of Ubuntu Phone with interest – it surely must get better than this – but this first device is one to write off to experience. Read more
