Reiser5 File-System Working On New Features Like Data Tiering, Burst Buffers

Reiser5 was announced back on New Year's Eve with support for local volumes and supporting parallel scaling out and other improvements over the long-in-development but never mainlined Reiser4. While Reiser5 was not met with enthusiasm, Edward Shishkin has continued working on this next-generation file-system and today announced the latest round of improvements.

Adaptive-Sync/VRR Seeing Port To xf86-video-modesetting Driver

Currently if wanting to use Adaptive-Sync/FreeSync variable refresh rate support of the AMDGPU DRM kernel driver you need to be using the xf86-video-amdgpu X.Org driver for proper handling as well, but a port of the DDX bits to the generic xf86-video-modesetting driver is in the works.

AMD Renoir Temperature Monitoring To Come With Linux 5.8

When it comes to the support for AMD Ryzen 4000 "Renoir" laptop support under Linux, as outlined in my testing so far this month the main caveat is needing Linux 5.6~5.7 for good graphics support but on the likes of Ubuntu 20.04 LTS with Linux 5.4 you will not have GPU acceleration. At least in the case of the Lenovo IdeaPad 5 I have been using to test, you also need Linux 5.7 Git for battery sensor support. Another item that in turn is coming with Linux 5.8 is CPU temperature reporting for the Renoir processors.

100+ Benchmarks Of Amazon's Graviton2 64-Core CPU Against AMD's EPYC 7742

Last week Amazon AWS promoted their Graviton2 instances to general availability status with a variety of different sized EC2 instances as well as a bare metal instance for tapping the full potential of their new SoC that features 64 Arm Neoverse N1 cores. Last week we ran through many benchmarks looking at Graviton2 on EC2 and bare metal performance while here is a follow-up article with more benchmarks and looking at how the sixty-four core Arm Graviton2 compares to AMD's EPYC 7742 64-core CPU with and without SMT.

Open-Source NVIDIA/Nouveau Changes Submitted For Linux 5.8

There hasn't been too much to report on the open-source NVIDIA "Nouveau" kernel driver in some time since the enabling of Turing and no apparent progress on re-clocking to allow the graphics cards to hit their rated clock frequencies (the longstanding, number one limitation for this open-source driver), but some changes were sent in today for the upcoming Linux 5.8 kernel merge window.
