Friedrich Vock with Valve presented yesterday at XDC 2023 on the Mesa RADV Vulkan driver's ray-tracing performance. Last year at XDC 2022 it was dubbed "the world's slowest raytracer" but thanks to the work done by Valve and others, the RADV ray-tracing performance is now quite capable and also enabled by default since Mesa 23.2. The RADV ray-tracing performance also continues inching closer to the AMDVLK Vulkan performance for that official open-source AMD Vulkan driver...

Multi-grain(ed) timestamps had been submitted for Linux 6.6 to better deal with NFS where the once-per-jiffy coarse-grained timestamps aren't enough for (in)validating caches. Multi-grained timestamps sought to address that by optionally allowing for the more fine-grained timestamps when desired but not using that finer granularity everywhere due to the greater overhead costs. This feature though ended up being reverted weeks later due to subtle bugs being uncovered. Now though a new redux patch series has been posted for providing another attempt at multi-grained timestamps...

Following other Intel oneAPI components like Embree and OpenVKL introducing GPU acceleration via SYCL, today Intel released the open-source OSPRay 3.0 that rolls out initial GPU support for this portable ray-tracing engine...

Merged last week to the X.Org Server is support in the 2D-acceleration-via-OpenGL GLAMOR code for allowing OpenGL ES 3.0 (GLES3) shaders...

Kicking off XDC 2023 yesterday in Spain was Igalia's Melissa Wen talking about her work on color management with the open-source AMD Linux graphics driver stack to empower Valve's Linux work on the Steam Deck. That was followed by Joshua Ashton of Valve talking about their work on HDR and color management from the Steam OS / Gamescope side for the Steam Deck...

It's already that time of the Qt 6.5 long-term support (LTS) cycle where The Qt Company has shifted it over to being focused on access only to their commercial customers...

AMD today posted a set of interesting patches for enabling better integration of their AMDKFD (Kernel Fusion Driver, what is their compute kernel driver) memory management with Linux's DRM GEM ioctl API. In turn the code allows managing virtual address (VA) mappings in compute VMs with the GEM_VA ioctl interface for greater control of buffers imported via DMA-BUF...

The GNOME Foundation has named a new Executive Director for overseeing the foundation responsible for this leading open-source desktop environment...

Last week Intel announced the Arc Graphics A580 as a new mid-range DG2/Alchemist graphics card option that comes in between the entry-level Arc Graphics A380 and the higher-end Arc Graphics A750/A770. With the Arc Graphics A580 coming in at under $200, it's quite an interesting graphics card for those after open-source Linux driver support and/or those wanting to experiment with Intel's growing oneAPI software ecosystem with excellent open-source GPU compute support.

NVIDIA today published their first R545 Linux driver beta series with a number of shiny new features...

Debian 12 had aimed to have a merged "/usr" file-system layout similar to other Linux distributions, but The Debian Technical Committee earlier this year decided to impose a merged-/usr file movement moratorium. But now with Debian 12 having been out for a few months, that moratorium has been repealed...

Both AMD and Intel engineers have experienced a lengthy journey getting their latest virtualization security features into the mainline Linux kernel -- and one that is still ongoing...

In addition to Intel putting the finishing touches on Meteor Lake graphics support for the upcoming Linux 6.7 cycle, Intel's Habana Labs AI accelerator driver also has some notable changes for this next kernel version...

Google is proposing a new mseal() memory sealing system call for the Linux kernel. Google intends for this architecture independent system call to be initially used by the Google Chrome web browser on Chrome OS while experiments are underway for use by Glibc in the dynamic linker to seal all non-writable segments at startup...

Weston 13.0 Alpha was released today as the next iteration of this reference Wayland compositor...

Hours after Ubuntu 23.10 was released last Thursday it was discovered Ubuntu 23.10 ISOs contained malicious user translations for those using the Ukrainian translations within the Ubuntu Linux desktop installer. Canonical suspended the desktop ISOs until the translations could be fixed and ISOs re-spun. That's now happened and this afternoon Ubuntu 23.10 images are back online...

While Ubuntu 23.10 isn't a Long-Term Support (LTS) release, for those curious about the evolution of Ubuntu Linux performance for Intel Xeon Max (Sapphire Rapids with HBM2e) on this new release just six months out from the all-important Ubuntu 24.04 LTS, here are some benchmarks showing the dual Intel Xeon Max 9480 performance on a Supermicro X13DEM platform while comparing Ubuntu 22.04.3 LTS, Ubuntu 23.04, and the brand new Ubuntu 23.10.

While Friday's release of ROCm 5.7.1 hadn't mentioned any Radeon family GPU support besides the aging Radeon VII, it turns out AMD's newest open-source GPU compute stack is ready to go now with the Radeon RX 7900 XTX and is complete with working PyTorch support...
