Last year Canonical delivered an Intel TDX "tech preview" for Ubuntu 23.10 to experiment with using Intel Trust Domain Extensions (TDX) found on the latest Xeon server processors. With Ubuntu 24.04 LTS they began shipping a formal TDX software stack and now have rolled out an update to that software stack as a stable release update...

Some long-rotting code in Mesa has been flushed out today... Mesa 24.3 is now 11.6k lines of code lighter after removing support for the OpenMAX (OMX) API that was implemented as a Gallium3D state tracker long ago and hasn't seen any activity in recent years and the upstream OpenMAX standards work halted more than one decade ago...

Last month I wrote about Intel Linux engineers working on a new Efficiency Latency Control feature for their uncore driver. This ELC option allows for adjusting the behavior of the Intel uncore for efficiency versus latency characteristics. Those Intel ELC patches to the TPMI uncore driver are now queued up for merging with the upcoming Linux 6.12 cycle...

Excitement is building that the real-time kernel "PREEMPT_RT" support might finally be ready for the mainline kernel as soon as the upcoming Linux 6.12 merge window.

While Windows gamers seem mixed over the AMD Ryzen 9000 series processors, for creator, scientific / HPC, code development, and many other technical computing areas I remain very impressed by the Ryzen 9000 (Zen 5) series desktop processors more than one month into constant testing with these Granite Ridge chips. One of the areas I hadn't explored until now but made me curious given the mixed messaging around gaming was how well workstation graphics workloads were performing with the new processors. For this brief weekend article is a look at the workstation graphics performance between the Ryzen 9 9950X and former Ryzen 9 7950X/7950X3D processors.

The work written about earlier this year on New Intel Linux Patches Continue Working To Improve Hybrid CPU Task Placement looks like it will be merged for the upcoming Linux 6.12 cycle as the patches have now been queued into the power management subsystem's "-next" branch.

One of the security changes with AMD Zen 5 processors that I haven't seen AMD publicly mention at least not prominently is that the new cores are not vulnerable to Speculative Return Stack Overflow (SRSO). Unlike Zen 4 and prior, under Linux I noticed that Zen 5 is no longer affected by the SRSO "INCEPTION" vulnerability. But of course there does remain other CPU security mitigations in place carried over from Zen 4. For those wondering about the mitigation costs or if it's worthwhile running Zen 5 with the "mitigations=off" insane mode, here are some benchmarks.

Back in 2022 were a set of patches that allowed compiling the ARM64 Linux kernel from Apple macOS hosts. The intent was for developers just wanting to do some build/smoke testing from under an Apple Silicon device running macOS to see at least any kernel changes are successfully compiling on macOS with its LLVM/Clang-based toolchain. An updated form of those patches were posted today for review...

With this week's announcement of the Intel Core Ultra 200V Series "Lunar Lake" processors, I've been very eager to try out the Meteor Lake successor for Linux testing. As sadly is usually the case, for delivering Linux support details and performance benchmarks around launch-time I'm typically left buying a laptop retail for Linux testing. In this case after seeing the Lunar Lake laptops announced this week and their availability, I ended up settling on the ASUS Zenbook S 14 (UX5406SA-S14.U71TB) for the initial Core Ultra 200V series Linux review...
