  • IGT Is Helping Keep Intel's Display Driver & Other DRM/KMS Drivers In Good Shape

    Formerly known as Intel GPU Tools, the scope of "IGT" has been expanding now for providing tools and functionality testing not only around the Intel DRM/KMS driver but also the other mainline Linux display drivers.

    The tool goes just by IGT these days with the scope expanding beyond just supporting the Intel driver, but the focus remains on providing good test coverage and various features for testing DRM/KMS code. IGT ships with tests around various hardware/driver-specific interfaces as well as PRIME buffer sharing, kernel mode-setting, GEM memory management, and other test/tooling programs.

  • Intel Sends In Their Last Batch Of Graphics Driver Feature Updates For Linux 5.1

    As anticipated with the DRM-Next feature cutoff upon us for the next kernel cycle, Intel's open-source developers today sent out their last planned set of feature changes slated for the Linux 5.1 kernel cycle.

    In preparation for the Linux 5.1 kernel cycle that will officially get underway when Linux 5.0 debuts around the end of February, Intel has already queued a lot of new material into the DRM-Next staging area. That earlier work most notably includes enabling Fastboot graphics by default for newer generations of graphics hardware for enhancing the boot experience. That Fastboot support by default is for Skylake and newer as well as various Atom SoCs. Also notable is Coffeelake GVT support for graphics virtualization. And the pull requests to DRM-Next over recent weeks have also included various Icelake fixes and other low-level improvements and code clean-ups.

  • AMDGPU Sends In More Linux 5.1 Updates With Seamless Boot Bits, FreeSync Fixes

    With the cutoff this weekend of new material in DRM-Next that hopes to make it in the upcoming Linux 5.1 cycle, besides Intel sending in a last batch, so has AMD with some more AMDGPU changes for this next version of the Linux kernel.

    The Linux 5.1 material for AMDGPU already queued include PCI Express bandwidth utilization being exported to user-space now via sysfs, initial BACO (Bus Active, Chip Off) support for Vega, exposing shader and memory clocks via hwmon, delta color compression on scan-out surfaces, and other changes. A secondary pull brought Vega 20 fixes and other miscellaneous fixes.

Variscite unveils two i.MX8 QuadMax modules

Variscite announced Linux-powered “VAR-SOM-MX8” and “SPEAR-MX8” modules with an up to an i.MX8 QuadMax SoC plus up to 8GB LPDDR4 and 64GB eMMC. It also previewed a VAR-SOM-6UL COM. At Embedded World next week in Nuremberg, Germany, Variscite will showcase its Linux and Android driven i.MX8-family computer-on-modules, including new VAR-SOM-MX8 and SPEAR-MX8 modules that feature NXP’s highest-end i.MX8 SoC up to a QuadMax model (see farther below). We have already covered most of the other showcased products, including the 14nm fabricated, quad -A53 i.MX8M Mini based DART-MX8M-Mini. When we covered the DART-MX8M-Mini in September, Variscite didn’t have an image or product page, but both are now available here Read more

Programming: Developer Happiness, Rblpapi 0.3.8 and Python

  • Developer happiness: What you need to know
    A person needs the right tools for the job. There's nothing as frustrating as getting halfway through a car repair, for instance, only to discover you don't have the specialized tool you need to complete the job. The same concept applies to developers: you need the tools to do what you are best at, without disrupting your workflow with compliance and security needs, so you can produce code faster. Over half—51%, to be specific—of developers spend only one to four hours each day programming, according to ActiveState's recent Developer Survey 2018: Open Source Runtime Pains. In other words, the majority of developers spend less than half of their time coding. According to the survey, 50% of developers say security is one of their biggest concerns, but 67% of developers choose not to add a new language when coding because of the difficulties related to corporate policies.
  • Rblpapi 0.3.8: Keeping CRAN happy
    A minimal maintenance release of Rblpapi, now at version 0.3.9, arrived on CRAN earlier today. Rblpapi provides a direct interface between R and the Bloomberg Terminal via the C++ API provided by Bloomberg (but note that a valid Bloomberg license and installation is required). This is the ninth release since the package first appeared on CRAN in 2016. It accomodates a request by CRAN / R Core to cope with staged installs which will be a new feature of R 3.6.0. No other changes were made (besides updating a now-stale URL at Bloomberg in a few spots and other miniscule maintenance). However, a few other changes have been piling up at the GitHub repo so feel free to try that version too.
