  • "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.

End of LibrePlanet 2019

  • Questioning and Finding Purpose
    This is copied over from my spiritual blog. I'm nervous doing that, especially at a point when I'm more vulnerable than usual in the Debian community. Still, this is who I am, and I want to be proud of that rather than hide it. And Debian and the free software community are about far more than just the programs we write. So hear goes: The Libreplanet opening keynote had me in tears. It was a talk by Dr. Tarek Loubani. He described his work as an emergency physician in Gaza and how 3d printers and open hardware are helping save lives. They didn't have enough stethoscopes; that was one of the critical needs. So, they imported a 3d printer, used that to print another 3d printer, and then began iterative designs of 3d-printable stethoscopes. By the time they were done, they had a device that performed as well or better than than a commercially available model. What was amazing is that the residents of Gaza could print their own; this didn't introduce dependencies on some external organization. Instead, open/free hardware was used to help give people a sense of dignity, control of some part of their lives, and the ability to better save those who depended on them. Even more basic supplies were unavailable. The lack of tourniquets caused the death of some significant fraction of casualties in the 2014 war. The same solution—3d-printed tourniquets had an even more dramatic result. Dr. Loubani talked about how he felt powerless to change the world around him. He talked about how he felt like an insignificant ant.
  • LibrePlanet Day 2: Welcoming everyone to the world of free software
    One of the most important questions that free software is facing in the year 2019 is: how do we make the world of free software accessible to broader audiences? Vast numbers of people are using software every day -- how do we relate our message to something that is important to them, and then welcome them into our community? In order to achieve our mission, we need to invite people and get them to use, create, and proliferate ethical software, until it replaces until all technology is free. Many of the best talks at LibrePlanet 2019 echoed a message for the free software community to focus on building a culture that's respectful and encouraging for new people, respecting a wide variety of personalities and values. The first way to get people invested in the culture of free software is to make it fun, and that was the focus of the morning keynote, "Freedom is fun!", delivered by free software veteran Bdale Garbee. A prominent name in the free software world for decades, Bdale talked about how he has a habit of turning all of his hobbies into free software projects, starting with model rockets.

Python Programming: PyPy 7.1 and More

  • PyPy v7.1 released; now uses utf-8 internally for unicode strings
    The interpreters are based on much the same codebase, thus the double release. This release, coming fast on the heels of 7.0 in February, finally merges the internal refactoring of unicode representation as UTF-8. Removing the conversions from strings to unicode internally lead to a nice speed bump. We merged the utf-8 changes to the py3.5 branch (Python3.5.3) but will concentrate on 3.6 going forward. We also improved the ability to use the buffer protocol with ctype structures and arrays.
  • PyPy 7.1 As The Well Known Alternative Python Implementation
    Last month brought the release of PyPy 7.0 as the JIT-ed performance-optimized Python implementation. PyPy 7.0 brought alpha Python 3.6 support, an updated CFFI module, and other enhancements. Out now is PyPy 7.1 as its successor.
