X.Org's GLAMOR 2D Performance Continues To Be Tuned

While GLAMOR has already been around for a number of years as a means of providing generic X11 2D acceleration over OpenGL for the X.Org Server, it's a seemingly never-ending process to optimize its code-paths for best performance. More improvements are en route for making GLAMOR 2D faster, which should especially be helpful for Raspberry Pi users making use of the VC4 driver stack on this very slow-speed hardware.

The Student Working On "Soft" FP64 Support Is Good News For Older GPUs

This summer the student developer Elie Tournier participated in Google Summer of Code to develop a "soft" double-precision floating-point library for Mesa. While GSoC is past, it appears he is committed to seeing this library through and getting into Mesa. With potential soft/emulated ARB_gpu_shader_fp64 support, this could be good news for those GPUs lacking real double precision support.

NVIDIA's Proposal For A New API Better Than GBM Has Already Made Some Progress

On the first day of the XDC2016 conference this week in Finland NVIDIA presented over their GBM vs. EGLStreams debate that's been ongoing for months with NVIDIA's lack of GBM API support by their driver being what's preventing the binary blob from working with current-generation Wayland compositors. In that session they called for a new community-driven API to suit the needs of device memory / surface allocation and could succeed the Generic Buffer Manager. By the end of XDC2016, some progress has already been made.

XDC2016 Day 1: GLVND, Tizen Wayland/Vulkan, PRIME Sync

Covered so far today on Phoronix, the first day of XDC2016 Helsinki, were NVIDIA's work on Linux HDR support, how Google's Android Runtime on Chrome uses Wayland, and the NVIDIA surface allocation API debate continued as a prerequisite to seeing mainline NVIDIA Wayland support in the compositors. There were also other notable presentations today.

NVIDIA Presents Over GBM vs. EGLStreams, The Big Wayland Support Debate Continues

James Jones of NVIDIA just finished taking the stage at XDC2016 where he was talking about Unix device memory allocation, which comes down to the big EGLStreams vs. GBM debate... A.k.a. NVIDIA pushing a different approach for their Wayland support from the Wayland compositors currently focusing around GBM for buffers. This debate is leading towards the development of a new API.

Raspbian Likely To Use Firmware-Based KMS For Raspberry Pi As Temporary Measure

Eric Anholt has been working at Broadcom for more than two years to develop the "VC4" open-source Linux graphics driver stack consisting of the DRM/KMS kernel driver and VC4 Gallium3D driver in user-space. While there's been 2+ years of work and tons of progress made, it's still not feature-complete compared to the older proprietary driver and as an interim solution Eric has hacked up a firmware-based KMS path.

Modesetting, PRIME Cursor Improvements Land In X.Org Server

With X.Org Server 1.19 being quickly scheduled for release next month, the merge window's closure is imminent (in fact, already a few days past the original proposal). Today some last minute xf86-video-modesetting and cursor changes landed.

The Threaded Input Support In X.Org Server 1.19

As covered previously, threaded input finally landed in the X.Org Server. It's 2016, and these patches had even been sitting around for a few years with no action, while finally this beneficial feature will be shipping with next month's X.Org Server 1.19 release.

X.Org Server 1.19 Proposed For Release Next Month

It's been since last November that X.Org Server 1.18 was released and while the project previously stuck to a six month release cadence, that didn't happen for xorg-server 1.19. Now, however, out of the blue Keith Packard has put together a proposal for quickly shipping it next month.

Arcan: A New Open-Source Display Server Built Atop A Game Engine

What happens when a game engine meets a display server meets a multimedia framework? Oh yeah and whereby the behavior is controlled with Lua. No, it's not a joke, just the latest creation in the open-source world. Say hello to Arcan as a new Linux display server.

X.Org's Indirect GLX State Is Frightening Researchers

Researchers and scientists appear up in arms this week over the state of Indirect GLX (IGLX) in the X.Org Server and the potential they'd lose the remote OpenGL rendering support they've been accustomed to using for seeing visualizations from clusters / super-computers on their workstations.
