A few weeks back I reviewed the SilverStone XE360-SP5 and XE04-SP5 cooling solutions catering to AMD EPYC 9004/9005 Socket SP5 processors. These coolers worked well with 400 Watt EPYC processors and especially the XE360-SP5 all-in-one liquid cooling was very performant and practical with today's server CPU TDPs ever increasing. After that SilverStone mentioned to me they had a new heatsink that could run up to 13 degrees cooler than the XE04-SP5 4U air cooler... Talk about intriguing. Meet the new SilverStone XED120S-WS for high-end air cooling for up to 450 Watt processors while working with multiple Intel and AMD CPU sockets.

Back for the Linux 6.12 kernel EROFS introduced support for file-backed mounts to help with container and sandboxing use-cases. As part of the EROFS "fixes" merged yesterday to the Linux 6.13 kernel, file-backed mounts are now using buffered I/O by default to speed-up container start times...

Last week with the availability of the Intel Arc B-Series Battlemage graphics cards I ran benchmarks looking at the GPU compute performance, Linux gaming benchmarks, and also the workstation graphics capabilities. The Intel Arc B580 graphics showed some nice generational uplift under Linux for most workloads but there were some anomalies where clearly the Intel Linux graphics driver had room to better optimize the new Xe2/Battlemage graphics support. Windows benchmarks of the Intel Arc B580 also showed it performing more competitively to the likes of the GeForce RTX 4060 compared to what I was seeing under Linux. Thus I spent the past few days working on some Windows 11 vs. Ubuntu Linux graphics benchmarks for both Intel Arc Graphics of Alchemist and Battlemage GPUs to see how the performance compares.

Fedora is among the Linux distributions that package up the Intel Compute Runtime stack to make it easy to run OpenCL and oneAPI Level Zero workloads on Intel graphics hardware via the distribution package manager and without having to jump through any extra hoops. But now with upstream Intel Compute Runtime dropping support for Ice Lake and older leaves the Fedora support in a pickle. Currently they are focusing on the "legacy" branch with older hardware support but for Fedora 42 are looking at upgrading the support to focus on newer Intel graphics hardware support while leaving that older hardware support behind...

It's not too often that "fixes" to the Kernel-based Virtual Machine (KVM) are noteworthy but today is an interesting exception with among the KVM fixes sent in today ahead of the Linux 6.13-rc3 tagging is for beginning to deal with a "hilarious/revolting" performance regression affecting recent generations of Intel processors. This performance regression won't be fully worked around until Linux 6.14 but at least there is an interim step in place once the code is merged later today...
