For years LLVMpipe has been around as a superior software-based OpenGL implementation for those without a working GPU / hardware driver support or needing to test a bit of GL code along a vendor-neutral path. LLVMpipe thanks to leveraging LLVM is more performant than the traditional Mesa software rasterizer or similar avenues like Softpipe. Finally as we hit 2021, SWRAST has been removed from the Mesa code-base...
NVIDIA's RTX 30 "Ampere" launch was quite a success for 2020 along with new Jetson products and more. Meanwhile on the Linux front this year NVIDIA's proprietary driver continued providing same-day support, features roughly at parity to Windows, and little bread crumbs of open-source support so far. But there still are indications of more possible open-source actions to come as well as potentially better Wayland support to look forward to in 2021...
Fedora Workstation 33 successfully switched over from EXT4 to using Btrfs as its default file-system. Now with Fedora 34 due out in the spring we are seeing Fedora beginning to make use of more features offered by Btrfs...
At the start of Q4, Intel released Media SDK 20.3 with AV1 accelerated decode, Rocket Lake, DG1/SG1 discrete GPU support, and other improvements. Now to end out the quarter is a new release coming in at version 20.5.1...
There are many new features with the Linux 5.11 kernel that is presently under development but one of the ones I've been more curious about for how well it works is the Intel "workload hints" that can be passed via its thermal framework. This is about providing the system with hints of workloads being run to optimize the thermal/power properties.
KDE had a very eventful year even with the pandemic where it saw its Wayland support come together quite well that it's usable on a day-to-day basis, KWin has been seeing some renewed attention, and there was much application work as well as fixes and polishing throughout the massive KDE ecosystem...
With it recently being noticed that the Linux AES-NI XTS performance regressed big time from the return trampolines "Retpolines" enacted nearly three years ago as a defense against Spectre, here are some benchmarks looking at the performance cost involved to this day using Retpolines and the impact on the XTS encryption/decryption performance measured by cryptsetup that is used for setting up encrypted disks under Linux...
