On Friday a big set of patches affecting the AMDGPU/Radeon/AMDKFD kernel drivers were submitted for DRM-Next to queue until the Linux 6.5 kernel merge window opens in the coming weeks. A lot of new feature code is part of this pull for benefiting new hardware, continuing to refine AMD GPU power management under Linux, and more.
With Intel TDX and AMD SEV-SNP for better securing virtual machines on the mainline Linux kernel, memory is accepted/initialized immediately at boot time by the VMs although the capability exists to have "unaccepted memory" where that memory is only dealt with by the VMs later on or on an as-needed basis. For two years now Intel engineers have been working on this unaccepted memory support and this week posted their thirteenth iteration of these fundamental Linux kernel patches.
The Portable Computing Language "PoCL" began as an open-source CPU-based OpenCL implementation that has become quite a comprehensive implementation over the years. But in leveraging the LLVM/Clang compiler stack, over time PoCL has grown beyond just a CPU implementation to also support OpenCL execution on NVIDIA GPUs, AMD HSA-capable GPUs, and more. The latest now coming with PoCL 4.0 is support for Intel Level Zero execution for running this OpenCL implementation over Intel Arc Graphics GPUs.
Serpent OS started out as a new Linux distribution started by Ikey Doherty, the same developer that rose to fame for starting the Solus Linux distribution prior to a hiatus. Serpent OS was getting off the ground when the surprise full-circle announcement came in April that Solus Linux would build off Serpent OS.
KDE developer Nate Graham began his weekly development recap by noting that Plasma 6.0 development continues and its stability is improving daily as well as seeing new features.
Kicking off a number of interesting articles over the week ahead for the Phoronix 19th birthday week is a fresh look at how AMD's official open-source Linux Vulkan driver "AMDVLK" compares to Mesa's RADV Vulkan driver that tends to be more popular with Linux gamers and is the driver backed by Valve, Red Hat, and other stakeholders.
Linux laptop/desktop vendor System76 has made some improvements to their Coreboot open firmware offerings to benefit their latest Intel Core 13th Gen "Raptor Lake" wares as well as prior generation devices.
Red Hat has decided they will be doing less work on desktop applications and will stop shipping LibreOffice as part of a future Red Hat Enterprise Linux release (presumably RHEL10). This is also limiting Red Hat's engagement in working on LibreOffice packaging for Fedora while the hope is that the Flatpak'ed LibreOffice will fill the void.
On Monday, 5 June, will mark 19 years since I started Phoronix.com to focus on Linux hardware reviews.
It's almost a daily occurrence to find interesting Linux kernel patches (and to other open-source projects too!) by Intel's large cabal of open-source engineers. The latest crossing my radar is for allowing the Linux "intel_idle" driver to run inside virtual machine (VM) guests.
The Linux 1-Wire "w1" subsystem is used for supporting drivers with hardware that communicates via a single wire (plus ground) in a simple master-slave configuration The Linux kernel has drivers such as for W1 over GPIO, i2c to W1 bridge, and supporting some very old hardware. The W1 subsystem hasn't seen much work recently while for the upcoming Linux 6.5 cycle will be seeing a larger update.

There is a Linux kernel scheduler patch now queued via TIP's sched/core branch that can help with task scheduling on AMD processors sporting multiple last-level caches (LLCs / L3 cache) per die. This minor improvement came after a discovery by a Linux kernel developer on his AMD Zen 2 desktop.
Chinese hardware vendor Loongson is working on extending the open-source, reverse-engineered Etnaviv Linux kernel graphics driver so it has PCI device support and in turn will work with their hardware based on the Vivante graphics IP.
Intel engineer Peter Zijlstra on Wednesday posted the latest patches for the EEVDF scheduler, the Earliest Eligible Virtual Deadline First approach that is based on a research paper from the late 90's. Ultimately the hope is for EEVDF to replace the existing CFS scheduler code.
For those interested in GPU overclocking, AMD has posted the patches for implementing the "legacy" OverDrive overclocking infrastructure for newer SMU13-based Radeon RX 7000 series graphics cards with the AMDGPU open-source Linux kernel driver.

Following kernel developers and those testing the kernels on affected hardware over the US holiday weekend, it's believed the issue has been tracked down to one missing patch that is a one line of code being deleted.
One of the new features of Intel Xeon Scalable 4th Gen "Sapphire Rapids" server processors is support for Trust Domain Extensions (TDX) but for this generation is only being activated for CPUs going to select cloud providers. Intel TDX allows better isolating virtual machines from the VMM/hypervisor and other non-TD software on the platform.
