Kernel/Graphics: AMD, Intel and Mesa

  • AMD vs. Intel Contributions To The Linux Kernel Over The Past Decade

    Driven by curiosity sake, here is a look at how the total number of AMD and Intel developers contributed to the upstream Linux kernel during the 2010s as well as the total number of commits each year from the respective hardware vendors. 

    These numbers were obtained by looking at the Linux kernel commits in Git from AMD.com and Intel.com addresses. Granted, sometimes developers from both companies will use their personal email addresses rather than the corporate ones, but for this comparison is looking solely at the Git commits from the respective corporate domains.

  • Linux k10temp Driver For AMD CPUs Updated To Better Handle Power/Temp Analysis

    As we have been eagerly talking about for the past week, the Linux kernel's k10temp driver was updated for better AMD CPU CCD temperatures and voltage/current reporting. Those improvements have been quickly evolving thanks to the work of the open-source community with AMD still sadly holding the datasheets concerning the power/temperature registers close to their vest. A new version of k10temp was sent out on Wednesday. 

    As reported earlier this week, these k10temp improvements could land for the upcoming Linux 5.6 but additional testing is needed. While Zen 2 CPUs have been shipping for months, these k10temp improvements are only coming now thanks to HWMON maintainer Guenter Roeck who continues working on this driver in cooperation with the community as AMD currently isn't releasing documentation/datasheets concerning the power/thermal registers or any reference code for that matter... Many Linux desktop users dream of seeing something someday like AMD Ryzen Master coming to Linux. 

  • Gutting Out Intel MPX Support To Be Finished Up In The Linux 5.6 Kernel

    The Linux support for Intel MPX has already been pretty much dead since the GCC 9 compiler dropped support for MPX. Kernel developers following that began working to remove MPX from the kernel over not having the compiler support, MPX not being widely used, and also not much code movement on the kernel side. Memory Protection Extensions (MPX) was talked up years ago by Intel for allowing the checking of pointer references at run-time to avoid buffer overflows and other potential related vulnerabilities. But in reality it didn't become too popular with developers while AddressSanitizer and other compiler sanitizer infrastructure has become more used and without the need for special bits in the CPU. Intel themselves meanwhile have deprecated MPX and say the support won't be available on future CPUs, hence not being concerned much about the Linux support departing.

  • Mesa 20.0 branchpoint planned for 2020/01/29, Milestone opened
    Hi list, due to some last minute changes in plan I'll be managing the 20.0
    release. The release calendar has been updated, but the gitlab milestone wasn't
    opened. That has been corrected, and is here
    https://gitlab.freedesktop.org/mesa/mesa/-/milestones/9, please add any issues
    or MRs you would like to land before the branchpoint to the milestone.
    
    Thanks,
    Dylan
    
  • Mesa 20.0 Feature Development Is Ending Next Week

    Mesa developers are planning to end feature work on Mesa 20.0 next week as this first quarter update to the Mesa 3D graphics stack.

    There has been a heck of lot building up for Mesa 20.0 including many ACO optimizations, many RadeonSI and RADV improvements around GFX10/Navi, Intel Gallium3D improvements, OpenGL 4.6 with NIR by default for RadeonSI, NIR support for LLVMpipe, Vulkan 1.2 for Intel ANV and Radeon RADV, and a whole lot more... My usual feature overview will be out after the code has been branched.

Education With Moodle and Open-Source Textbooks (Open Access)

  • Transforming the traditional classroom with Open Education

    The Tamarind Tree school in Dahanu, India, encourages self-learning through open educational resources and open technology At Tamarind Tree, the traditional classroom and traditional teacher role do not exist. Using open source software and open educational resources, the school has developed an entire digital ecosystem, with their LMS built on Moodle “My Big Campus” in the centre. Each day, students access the learning content and go through activities independently, nurturing their curiosity and self-assurance. In this setting, the role of the teacher is not as someone who delivers content, but more like a facilitator who mentors the children during their learning journey. As well as guiding the children through what they’re learning, when a teacher detects that a student is having difficulties with a topic or concept, or requires help, they will schedule one-on-one meetings where they both research and learn together.

  • Beaufort County Community College saves students over $50,000 on new textbooks

    New textbooks, called Open-Source Textbooks, are saving students more than $50,000 per semester at Beaufort County Community College (BCCC). Open-Source Textbooks are licensed under an open copyright license and made available online to be freely used by students and teachers. Some professors at BCCC are using Open-Source Textbooks to decrease the cost of student's education and help them stretch financial aid or scholarships. Professors seek out Open-Source Textbooks from a curated online library developed by academics from all over the country, then add additional material.
