Linux Hardware Reviews & Performance Benchmarks, Open-Source News

One of the exciting Intel innovations to the Linux kernel this year has been around the Cache Aware Scheduling for helping to deliver better performance on modern CPUs with multiple last level caches. The kernel patches have yet to be upstreamed but testing has shown to be quite promising for grouping tasks sharing data to the same LLC domain to help reduce cache misses and cache bouncing. Those wishing to learn more about Cache Aware Scheduling, there was a presentation on it last week by Intel engineers Tim Chen and Chen Yu at the Linux Plumbers Conference 2025 in Tokyo.

As part of my various year-end comparison benchmarking, I recently ran some tests looking at how the Radeon RX 9000 series RDNA 4 performance has evolved since its debut near the beginning of the year. The Vulkan ray-tracing performance in particular was standing out this year as having evolved quite nicely while for conventional OpenGL and Vulkan performance the performance has been largely stable this year with its great at-launch support.

Stemming from a security researcher and his team proposing a new Linux Security Module (LSM) three years ago and it not being accepted to the mainline kernel, he raised issue over the lack of review/action to Linus Torvalds and the mailing lists. In particular, seeking more guidance for how new LSMs should be introduced and raised the possibility of taking the issue to the Linux Foundation Technical Advisory Board (TAB).

15 December 03:52 PM EST - Fedora - Fedora 44 ARM Laptops

Longtime Red Hat engineer Hans de Goede who worked on many Intel/AMD laptop enhancements over the years left Red Hat and ended up joining Qualcomm.

15 December 12:00 PM EST - Hardware - AmpereOne M With Oracle Cloud A4

Back in July 2024, Ampere Computing announced AmpereOne M on their road-map for Q4'2024 to provide AmpereOne with 12 channel DDR5 memory compared to eight memory channels with the original AmpereOne processors. Then this past May the AmpereOne M SKUs were announced while Ampere Computing stated these "M" processors had been shipping since Q4 of last year. Since then we haven't seen or heard anything more about AmpereOne M nor the AmpereOne MX processors with up to 256 cores. Since then, the acquisition of Ampere Computing by SoftBank also was completed that made us wonder more about impacts to the roadmap and what hardware may or may not make it out to market. Well, today, we are finally seeing AmpereOne M availability in the public cloud with the new Oracle Cloud A4 instances.

Over the past year Intel engineers have worked a lot on Cache Aware Scheduling for the Linux kernel. The yet-to-be-merged functionality allows for the Linux kernel to better aggregate tasks sharing data to the same last level cache (LLC) domain to reduce cache misses and cache bouncing. The Cache Aware Scheduling development was led by Intel but helps other CPU vendors too for processors with multiple cache domains. Back in October I showed some nice performance wins for AMD EPYC Turin with Cache Aware Scheduling while today's article are some benchmarks of the newest CAS code and looking at the performance benefit on Xeon 6 "Granite Rapids" processors.

11 December 06:00 AM EST - Mesa - VK_EXT_present_timing

Last month the Vulkan VK_EXT_present_timing extension was merged after 5+ years in development. VK_EXT_present_timing ended up debuting at the end of November within the Vulkan 1.4.335 spec update to much excitement for providing functionality to obtain information on the presentation engine's display for accurate timing information and to assist in scheduling a present to happen no earlier than a desired time. This is a big win for helping avoid game stuttering and more while now the Mesa support for it is nearly complete and could be merged soon.

Linus Torvalds merged the Device Mapper "DM" changes overnight that include one stand-out change for Linux 6.19.
