  • 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.

F(x)tec Pro1-X Announced – with physical keyboard, Lineage OS and Ubuntu Touch support but dated Snapdragon 835

Today, F(x)tec has re-launched their Pro1 smartphone, but renamed as Pro1-X and running LineageOS out of the box combined with compatibility with Ubuntu Touch OS. The phone has been developed in partnership with XDA, hence the name. The hardware remains the same which includes the dated Qualcomm Snapdragon 835 chipset; however, this phone isn't about raw power, it is a productivity tool with a strong focus on privacy. It will then combine the chipset with 8GB of RAM a 5.99-inch FHD+ AMOLED display, an 8MP front-facing camera, and a 12MP camera at the rear. Read more

  • Btrfs on CentOS: Living with Loopback | Linux Journal

    The btrfs filesystem has taunted the Linux community for years, offering a stunning array of features and capability, but never earning universal acclaim. Btrfs is perhaps more deserving of patience, as its promised capabilities dwarf all peers, earning it vocal proponents with great influence. Still, none can argue that btrfs is unfinished, many features are very new, and stability concerns remain for common functions. Most of the intended goals of btrfs have been met. However, Red Hat famously cut continued btrfs support from their 7.4 release, and has allowed the code to stagnate in their backported kernel since that time. The Fedora project announced their intention to adopt btrfs as the default filesystem for variants of their distribution, in a seeming juxtaposition. SUSE has maintained btrfs support for their own distribution and the greater community for many years. For users, the most desirable features of btrfs are transparent compression and snapshots; these features are stable, and relatively easy to add as a veneer to stock CentOS (and its peers). Administrators are further compelled by adjustable checksums, scrubs, and the ability to enlarge as well as (surprisingly) shrink filesystem images, while some advanced btrfs topics (i.e. deduplication, RAID, ext4 conversion) aren't really germane for minimal loopback usage. The systemd init package also has dependencies upon btrfs, among them machinectl and systemd-nspawn. Despite these features, there are many usage patterns that are not directly appropriate for use with btrfs. It is hostile to most databases and many other programs with incompatible I/O, and should be approached with some care.
