AMDGPU HDMI 2.1 FRL To Be Initially Disabled-By-Default

One of the most exciting developments in recent times for the open-source AMDGPU kernel graphics driver is HDMI 2.1 FRL support for the AMDGPU driver along with Display Stream Compression support as they work toward providing full HDMI 2.1 support for this open-source AMD Radeon driver. The details how AMD managed to pull this feat off given prior resistance from the HDMI Forum remains to be confirmed, but it's moving ahead and out today is the latest iteration of the HDMI 2.1 FRL+DSC patches...

[$] What is to be done about MGLRU?

"Reclaim" is the task of finding memory that can be taken away from its current user and put to better uses within the system; it is a core part of the memory-management picture. The addition of the multi-generational LRU (MGLRU) was meant to provide a better reclaim implementation than the "traditional LRU" that preceded it, but MGLRU has complicated the situation instead. No fewer than three memory-management-track sessions at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit were focused on MGLRU, with an eye toward integrating it more fully, improving its performance, and addressing some problems encountered with Android systems.

Initial Benchmarks Of The SpacemiT K3 RVA23 RISC-V CPU With The K3 Pico-ITX

One of the RISC-V SoCs we have been most looking forward to this year is the SpacemiT K3 that features the X100 RISC-V cores that are RVA23 compliant and among the first readily available RVA23 RISC-V platform for running on the likes of Ubuntu 26.04 LTS. In this article is a preview of some very early benchmarks of the SpacemiT K3 with the new Pico-ITX single board computer offering.

[$] The tenth OpenPGP email summit

The OpenPGP Email Summit is an annual meeting for those who work on encrypted email and related topics. The tenth installment of this meeting took place in March 2026 and the minutes have now been published. As usual, a wide range of topics were discussed. Highlights included support for post-quantum cryptography (PQC) with multiple actors planning rollouts within this year, a promising new approach for making email signatures ubiquitous with the plan of making OpenPGP signed email a default, a new draft that brings reliable deletion (or "forward secrecy") features to OpenPGP, as well as a plan for transferring ownership of the OpenPGP.org domain.
