Mesa 21.0 Has Finally Killed The Classic "SWRAST" Software Rasterizer

Phoronix - Thu, 12/31/2020 - 13:00
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...

The Most Popular NVIDIA Linux News + Milestones Of 2020

Phoronix - Thu, 12/31/2020 - 09:20
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...

Phoronix - Thu, 12/31/2020 - 01:30
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.

A Look At The Big Impact To AES-XTS Encryption Performance From Spectre Retpolines

Phoronix - Wed, 12/30/2020 - 23:05
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...
