AMD has released a new version of AOMP, its LLVM/Clang compiler downstream where they stage their latest patches focused on OpenMP GPU offload support for their Radeon graphics cards / Instinct accelerators...

While the hostname on Linux systems is widely relied upon for different applications, setting the hostname is usually left up to user-space by the init system at boot. However, should any user-space processes try to read the system hostname prior to it being set, it could lead to unintended results. So now finally in 2022 there is a kernel parameter working its way upstream with "hostname=" should you want to ensure the hostname is set before user-space is started...

Given the recent releases of Ubuntu 22.04 LTS and Fedora 36 among other recent OS updates, it's time for a fresh look at how various Linux distributions are performing. This Linux benchmarking bout is looking at the Xeon Platinum 8380 2P "Ice Lake" performance across Arch Linux, Debian, openSUSE, CentOS Stream, AlmaLinux, Fedora, Ubuntu, and Intel's Clear Linux.

Last week I wrote about how well known Mesa developer Samuel Pitoiset who is employed by Valve already started working on GFX11 (RDNA3) support for RADV, the open-source Radeon Vulkan driver in Mesa that isn't officially supported by AMD but remains more popular than their own "AMDVLK" driver. More GFX11/RDNA3 preparation work remains ongoing and it's looking like if trends continue this open-source driver could be ready for RDNA3 graphics cards in time for launch...

Multi-Gen LRU (MGLRU) remains a very promising effort for enhancing Linux system performance and particularly about providing a superior experience when the Linux kernel is dealing with system memory pressure. MGLRU v11 was posted this week while we await to see if it will be mainlined come the v5.19 merge window...

Back in 2017 for the Linux 4.11 kernel the statx system call was added for allowing enhanced file information reporting. Since then various file-systems began adding Statx support and worked its way up into Glibc and the like in user-space for Linux finally having file creation time reporting and other attributes. Two separate statx-related additions are now working their way to the kernel...

Microsoft has made a lot of interesting developments and maneuvers over the past number of months for leveraging open-source Mesa for use by Windows Subsystem for Linux (WSL) and supporting various Khronos APIs atop Direct3D 12 for use when native drivers are lacking on Windows. This work so far has been focused on OpenGL, OpenCL, and Vulkan but Microsoft has now even implemented Direct3D 12 video API support within Mesa and leverages the VA-API state tracker support within Mesa...

Canonical continues investing a lot in ensuring a first-rate Ubuntu experience when using Microsoft's Windows Subsystem for Linux (WSL/WSL2) with Windows 10 and newer. Rather than needing to wait longer to see the fruits of that work in the next Ubuntu releases, Canonical has now made "Ubuntu Preview" available from the Microsoft Store to have a daily-updated, bleeding-edge Ubuntu experience...

With the Linux 5.18 kernel reaching stable in the next week or two there is basic support for Tesla's FSD chip.

Mesa's Radeon Vulkan driver "RADV" continues working on maturing its ray-tracing implementation after the initial code was merged last year. RADV ray-tracing is still treated as experimental and not as reliable as the proprietary NVIDIA Vulkan driver's ray-tracing support that has been around much longer, but it's getting there and at least is open-source -- unlike AMD's official AMDVLK driver that continues to not support Vulkan RT unlike their proprietary driver alternative...
