RADV's ACO Compiler Back-End Now Supported For Older AMD "Sea Islands" GPUs
The Valve-backed "ACO" compiler back-end for the open-source Radeon "RADV" Vulkan driver has added support now for AMD GCN 1.1 "Sea Islands" graphics cards.
Sea Islands includes the Radeon Rx 200 series with the R7 260/260X/290/295 series and these 2nd Gen GCN GPUs also ended up in the Radeon HD 7790, Radeon HD 8770, Radeon R7 360, Radeon R9 390/390X, and Radeon RX 455. Up to now the ACO compiler back-end has only supported GCN1.2/GFX8 and newer but with the latest Mesa 20.0-devel code as of today in Mesa Git there is now ACO support for GCN 1.1 Sea Islands.

Wayland's Weston 8.0 Reaches Alpha With EGL Partial Updates, Headless OpenGL
Weston 8.0 is another significant update for this Wayland reference compositor in it offers EGL_KHR_partial_update support to reduce GPU vRAM usage on supported drivers/GPUs thanks to handling partial screen updates, support for building the DRM back-end without Mesa's GBM, greater hardware planes usage, the Weston headless back-end now supports OpenGL, a direct display extension, HDCP support in the DRM back-end, and various other improvements / features.

weston 7.0.91
This is the alpha release for weston 8.0. Here is a highlight of the main new features: - DRM hardware planes should be used more effectively - Headless backend now supports OpenGL - DRM backend can now be built without GBM - EGL_KHR_partial_update is now used when available, reducing memory bandwidth usage on some GPUs - Logging framework improvements - Documentation for weston can now be built A lot of fixes have been merged too.

Mesa 20.0 Now Includes Intel's Gallium3D Driver To Build By Default
As part of the ongoing effort for Intel's plans to use their new Gallium3D OpenGL Linux driver by default on next quarter's Mesa 20.0 for Broadwell "Gen8" graphics and newer, another step in that direction was achieved on Friday.
Intel's "Iris" Gallium3D driver is still making good progress in its goal for Mesa 20.0 to switch the default "i965" classic driver to Intel Gallium3D for Broadwell and newer hardware. Earlier this week was adding a build-time option to change the Intel OpenGL driver default so those building from source or distribution vendors can change the default on their own with ease.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
