Vulkan 1.4.325 Released With Untyped Pointers Extension

Vulkan 1.4.325 was released on Friday with one new extension in tow: VK_KHR_shader_untyped_pointers for untyped pointers.

VK_KHR_shader_untyped_pointers adds Vulkan support for the SPIR-V SPV_KHR_untyped_pointers extension to provide untyped pointers as an alternative to strongly-typed pointers:
"It provides an alternative to strongly-typed pointers. Untyped pointers allow shader authors to reinterpret data accessed through memory and atomic instructions versus the data type declared

Linus Torvalds Rejects RISC-V Changes For Linux 6.17: "Garbage"

Linus Torvalds has used his authority to reject the RISC-V architecture changes for the Linux 6.17 kernel. The RISC-V updates won't land this cycle and will need to try again for v6.18 later in the year. Linus refers to at least some of the proposed RISC-V code as garbage along with being submitted rather late during the merge window.

Only on Friday were the RISC-V code update submitted for the Linux 6.17 merge window. The Linux

GNU/Hurd Now An Official Platform For SDL Cross-Platform Gaming Library

GNU/Hurd has made it as an official platform target within SDL that is the open-source library widely-used by cross-platform games and other applications for software/hardware abstractions across operating systems.

GNU/Hurd had already worked with SDL for a "long time" but now is an official platform to be able to enhance its support. The commit adding GNU/Hurd platform coverage to SDL explains:
"Add GNU/Hurd as platform

SDL has been building on GNU/Hurd for a long time,

GNOME Mutter On Wayland Adds ICC Profile Support, Backlight Improvements

There were a lot of interesting changes that landed in GNOME's Mutter compositor codebase to end out the weekend and ahead of next month's big GNOME 49 release.

First up, Mutter has merged support for setting Broadcast RGB support. This has been tested on Intel graphics so far and fixes the four year old bug report over having a way for setting the full RGB range output in GNOME on Wayland.

Mutter also merged wl_seat version 10 support. The updated Wayland seat protocol adds an "axis

Additional Intel Linux Drivers Left Orphaned & Maintainers Let Go

Well, it's an unpleasant afternoon in Linux land with more signs of the ongoing impact from Intel's corporate-wide restructuring. Just after writing about Intel's CPU temperature monitoring driver now left unmaintained/orphaned , more patches hit the public Linux kernel mailing list to mark additional Intel drivers as orphaned and removing maintainer entries for Linux developers no longer at Intel.

One of the new patches today drops one of the maintainers of the Intel Ethernet RDMA driver. The Intel Ethernet RDMA driver is still maintained as one

Intel CPU Temperature Monitoring Driver For Linux Now Unmaintained After Layoffs

There is yet more apparent fallout from Intel's recent layoffs/restructurings as it impacts the Linux kernel... The coretemp driver that provides CPU core temperature monitoring support for all Intel processors going back many years is now set to an orphaned state with the former driver maintainer no longer at Intel and no one immediately available to serve as its new maintainer.

A patch was posted a few minutes ago on the Linux kernel mailing list to mark the coretemp driver as orphaned. Longtime Intel Linux engineer Dave Hansen commented on the

Bcachefs Maintainer Comments On The LKML While Waiting To See What Happens

We still don't know what's going to happen for Bcachefs in the Linux 6.17 kernel even with the merge window set to end on Sunday with the Linux 6.17-rc1 release. Linus Torvalds commented over one month ago that they would be parting ways for Linux 6.17 . At the start of the Linux 6.17 merge window a Bcachefs pull request was submitted but nearly two weeks later it's still not been pulled and Linus Torvalds hasn't

AMD Linux Driver Prepares For Radeon RDNA4 "Kicker"

A few new firmware files were upstreamed today to the linux-firmware.git repository for supporting a new GFX12.0.1 (RDNA4) "Kicker" graphics processor. There was also an AMDGPU kernel graphics driver patch that just landed as well in Linux 6.17 for the RDNA4 Kicker variant.

Besides updating firmware files for various generations of existing AMD Radeon graphics hardware support, appearing today in linux-firmware.git are a few new firmware files for the first time: GC 1

DDR5-6400 vs. DDR5-4800 R-DIMM Performance For Threadripper 9980X / 9970X CPUs

Last week the Threadripper 9000 series began shipping and as shown in our launch-day Linux testing there was stunning performance with the 32-core Threadripper 9970X and 64-core Threadripper 9980X processors. Beyond the improvements thanks to the Zen 5 microarchitecture enhancements, the new Threadrippers while working as a drop-in replacement to existing TRX50 workstation motherboards now can handle DDR5-6400 R-DIMMs up from DDR5-480
