  • "Soft" FP64/INT64 Implementations Merged To Mesa, Intel Driver Already Making Use

    For those with older graphics processors, rejoice as with the upcoming Mesa 19.0 driver release it might now be possible to have OpenGL 4.0 thanks to software-based implementations of ARB_gpu_shader_int64 and ARB_gpu_shader_fp64 finally being merged to mainline. The FP64 one is most notable with that being a requirement for OpenGL 4.0 but some older GPUs lacking that capability for bumping past OpenGL 3.3.

    Going back to the summer of 2016 was a Google Summer of Code project by Elie Tournier to implement "soft" FP64 support using GLSL to help out older GPUs that otherwise couldn't expose OpenGL 4.0 due to not supporting ARB_gpu_shader_fp64. Elie Tournier has since gone on to work for Collabora but getting this code merged has taken quite some time.

  • Intel Developer Working On Adding HDR Display Support To Wayland / Weston

    While the Linux desktop's display stack has largely reached parity with Windows and macOS in recent years (most recently, the DRM core properties hitting Linux 5.0 around Adaptive-Sync / VRR), but one of the areas that has remained elusive has been for full HDR display support. We've seen NVIDIA working on nursing the X.Org-based display stack for HDR while now Intel appears to be working on the necessary Wayland changes.

    Back in 2016 is when NVIDIA began looking at the Linux shortcomings for HDR display support and ended up proposing the DeepColor X11 extension (still yet to be merged) and other efforts for an HDR Linux desktop compared to traditional SDR content. Now with Intel's Icelake processors coming out later in the year with "Gen 11" graphics and their Xe discrete graphics potentially coming next year, HDR display support is now on the minds of their open-source driver developers.

  • The Expected Linux Driver State For The Radeon VII

    With yesterday's surprise announcement of the Radeon VII "Radeon 7" as a new $699 7nm second-generation Vega consumer graphics card launching in early February, you may be wondering about the open-source Linux driver support state. While nothing official has come down the wire yet, here is what appears to be the state for this new Vega graphics card on Linux.

    AMD hasn't communicated yet about the Linux driver support for Radeon VII, I don't have any review sample or the like at this time, but given the number of questions since yesterday about Linux support, here's what I know based off my close monitoring of the AMD open-source Linux driver development.

Review: Sculpt OS 18.09

The Sculpt OS website suggests that the operating system is ready for day to day use, at least in some environments: "Sculpt is used as day-to-day OS by the Genode developers." Though this makes me wonder in what capacity the operating system runs on the machines of those developers. When I tried out the Haiku beta last year, the operating system had some limitations, but I could see how it could be useful to some people in environments with compatible hardware. In theory, I could browse the web, perform some basic tasks and develop software on Haiku. With Sculpt though, I was unable to get the operating system to do anything, from a user's point of view. The small OS could download packages and load some of them into memory, and it could display a graph of related components. Sculpt could connect to my network and mount additional storage. All of this is good and a fine demo of the Genode design. However, I (as a user) was unable to interact with any applications, find a command line, or browse the file system. All of this put a severe damper on my ability to use Sculpt to do anything useful. Genode, and by extension Sculpt OS, has some interesting design goals when it comes to security and minimalism. However, I don't think Sculpt is practical for any end-user tasks at this time. Read more

  • Tens to be disappointed as Windows 10 Mobile death date set: Doomed phone OS won't see 2020
    Microsoft has formally set the end date for support of its all-but-forgotten Windows 10 Mobile platform. The Redmond code factory said today that, come December 10, it's curtains for the ill-fated smartphone venture. The retirement will end a four-year run for a Microsoft phone effort that never really got off the ground and helped destroy Nokia in the process. "The end of support date applies to all Windows 10 Mobile products, including Windows 10 Mobile and Windows 10 Mobile Enterprise," Microsoft declared.
