RISC-V International, the global standards organization, today announced that the RVA23 Profile is now ratified. RVA Profiles align implementations of RISC-V 64-bit application processors that will run rich operating systems (OS) stacks from standard binary OS distributions. RVA Profiles are essential to software portability across many hardware implementations and help to avoid vendor lock-in. The newly ratified RVA23 Profile is a major release for the RISC-V software ecosystem and will help accelerate widespread implementation among toolchains and operating systems.

Each Profile specifies which ISA features are mandatory or optional, providing a common target for software developers. Mandatory extensions can be assumed to be present, and optional extensions can be discovered at runtime and leveraged by optimized middleware, libraries, and applications.

Key Components of RVA23 Include:

• Vector Extension: The Vector extension accelerates math-intensive workloads, including AI/ML, cryptography, and compression / decompression. Vector extensions yield better performance in mobile and computing applications with RVA23 as the baseline requirement for the Android RISC-V ABI.
• Hypervisor Extension: The Hypervisor extension will enable virtualization for enterprise workloads in both on-premises server and cloud computing applications. This will accelerate the development of RISC-V-based enterprise hardware, operating systems, and software workloads. The Hypervisor extension will also provide better security for mobile applications by separating secure and non-secure components.

I have an issue on my Lenovo Laptop where the Lenovo Active Pen 2 under Arch / CachyOS with GNOME on Wayland always recognises the eraser as pressed. While this is probably a libinput issue, I can’t wait for possibly months to get a fix on that side. While I will report this issue to them, I would like to fix the problem intermediately.

This was never a problem under Fedora with GNOME on Wayland. I think the problem might be that libinput on Arch loads the Wacom driver, while Fedora probably just fell back to the generic libinput driver. I got that idea because in GNOME settings my screen now is configurable in the Wacom settings, that never was the case on Fedora.

I stumbled across this thread, however, that is not viable in Wayland any more since there is no config file available for libinput. Is there any way I can force the libinput driver for the “Wacom HID 52C2 Pen” device under Wayland, while GNOME is not specifically exposing this setting?

Any pointers would be greatly appreciated :)

Edit: Scratch all that, I just tried the live ISO for Fedora 41 and found out it's not related to Arch. After some trial, it seems like this might actually be an issue with the 6.11 Kernel. After downgrading to 6.10.10 everything works fine again. I guess my new question is now where would I report this? Is this still a libinput or a Kernel upstream issue?

I finally did it and got an used RX 6950 XT to replace my GTX 1080 Ti. I've been using this card ever since I moved to Linux and now I'm wondering what exactly I have to do. On Windows it's mostly run DDU and install the new AMD drivers, everything else will probably work the same with Afterburner etc.

However, on Linux the only things I know are uninstalling the Nvidia drivers, removing GWE since that obviously won't work and installing Mesa.

What other steps do people recommend? I'm hyped to finally get properly working GPU acceleration in Firefox and other things like Steam, but is there anything I have to do to get that running? Also what tools are currently a must with an AMD card for some undervolting / overclocking and other functionality y'all can recommend?
