  • Mesa Developers Discuss LTO'ing + PGO'ing Builds For Greater Performance

    Making use of Link-Time Optimizations (LTO) and Profile Guided Optimizations (PGO) is currently being talked about by Mesa developers for their release builds in potentially squeezing out better performance.

    Dieter Nützel shared that when using LTO and PGO compiler optimizations on Mesa, he's able to get RadeonSI's binary size 40% smaller and 16~20% faster for this OpenGL driver. Link-time optimizations are about as the name implies running optimization passes during the linker phase when able to analyze the to-be-produced binary in full rather than the individual object files in order to allow for more inter-procedural optimizations on the whole program.

  • Open-Source Nouveau Extended To Support The GeForce 16 Series With Hardware Acceleration

    With the big Linux 5.6 kernel on the open-source NVIDIA "Nouveau" driver side there is finally accelerated support for the GeForce RTX 2000 "Turing" graphics cards (when paired with binary-only microcode). With that initial cut support is no GeForce 16 series Turing support, but that is now on-deck for Linux 5.7.

    While the GeForce 16 series is Turing based and just without the RTX cores, firmware/microcode differences and other subtle changes were needed to the Nouveau kernel driver for enabling its open-source hardware accelerated support.

  • Radeon "sisched" Scheduler Is Made Obsolete By RADV's ACO Back-End

    It's been years since last hearing anything about sisched as the SI machine instruction scheduler that started out for the RadeonSI OpenGL driver and was ultimately supported by the RADV Vulkan driver too.

    Years ago, SISCHED helped offer better open-source AMD Radeon Linux gaming performance but those days are over. The scheduler was made part of the AMDGPU LLVM back-end and that sisched code hasn't seen any new work in ages. Now with Valve's ACO taking off so well since its mainlining in Mesa 19.3 as an alternative to the AMDGPU LLVM back-end, it pretty much nails the coffin on SISCHED.

  • Intel Blackhole Render Support Lands In Mesa 20.1

    Intel Blackhole Render support was finally merged today for the new Intel "Iris" Gallium3D OpenGL driver default, the older i965 driver for pre-Broadwell hardware, and also the Mesa state tracker for Gallium3D drivers.

    Proposed back in 2018 was the Intel blackhole render extension for OpenGL / GLES as an extension to disable all rendering operations emitted to the GPU through OpenGL rendering commands but without affecting OpenGL pipeline operations.

Review: Linuxfx 10.6

The Linuxfx distribution, which is sometimes referred to as "Windowsfx" on the project's website and in various applications, is based on Linux Mint and appears to one have overarching goal: to look and act as much like Microsoft Windows 10 as possible. The distribution does this by adjusting the desktop, theme, icons, and settings panel to look as much like Microsoft's operating system as possible. The project then adds in WINE, a virtual assistant application, and adjusts application launchers to resemble those used by Windows. Under the hood though Linuxfx is still very much running Linux Mint packages as its base with the Cinnamon desktop environment. I was surprised to find the distribution's recent stable release, 10.5, has been removed from the project's download mirrors. The only edition available to me was a new version labablled 10.6 which runs on 64-bit (x86_64) machines exclusively. The download for this live media is 3.8GB in size. Note: Following writing this review, just before publication, the Linuxfx team removed the free downloads for version 10.6 (and earlier versions of the distribution) from their website. The distribution is now a commercial offering. Read more

LibreOffice 10th Anniversary

Today is LibreOffice 10th Anniversary: it is a significant achievement for the project, and a date to remember for all community members. We have created a video based on pictures of community members and a few events, in two versions: a long one, for blogs and websites, and a short version for social media. Read more

Linux 5.9 RC7

  • Linux 5.9-rc7
    So we finally have all the issues I know about sorted out - the fix
    for the VM issue I mentioned in the rc6 announcement is here, as is
    the fix for the slab corruption issue that was separately discussed,
    along with another silly page locking bug one-liner fix.
    
    But while I do now know of any remaining gating issues any more, the
    fixes came in fairly late. So unless I feel insanely optimistic and/or
    a burning bush tells me that everything is bug-free, my plan right now
    is that I'll do another rc next Sunday rather than the final 5.9
    release. And btw, please no more burning bushes. We're kind of
    sensitive about those on the West coast right now.
    
    Anyway, while the MM side is what kept me on my toes last week, most
    of the changes here are actually drivers and networking. And
    networking drivers. With a small smattering of documentation and
    filesystem fixes and other noise thrown in.
    
    Shortlog appended, but what I really hope you all will do is to give
    it a nice good testing. One extra week or rc kernels will help, but
    only if people actually try this out.
    
    So.. Please?
    
                  Linus
    
  • Kernel prepatch 5.9-rc7

    The 5.9-rc7 kernel prepatch is out for testing. "But while I do now know of any remaining gating issues any more, the fixes came in fairly late.

  • Linux 5.9 Stable Expected In Two Weeks, But For Now Is Linux 5.9-rc7

    Linus Torvalds just released Linux 5.9-rc7 as the newest weekly test candidate for Linux 5.9. Due to the regressions encountered this cycle and prominent issues being resolved late, he's looking at releasing Linux 5.9 in two weeks time rather than next week.
