Page Cache Sharing Looks To Be Very Beneficial For EROFS Containers
One of the features being worked on for a while with the read-only EROFS file-system is page cache sharing. Besides EROFS being popular on some mobile/embedded devices, this open-source read-only file-system has been quite popular for container usage and there this page cache sharing functionality can provide some significant reductions in RAM usage… ⌘ Read more

Intel’s Cache Aware Scheduling Presentation At LPC 2025
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 wa … ⌘ Read more

Cache Aware Scheduling Raises Performance For Intel Xeon 6 Granite Rapids
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 show … ⌘ Read more

AMD EPYC 7773X “Milan-X” Performance & Power Nearly Four Years Later
Nearly four years have passed since AMD launched their EPYC Milan-X processors with 3D V-Cache. When recently rearranging some servers in the lab and realizing the four year anniversary was coming up in March, curiosity got the best of me in wondering where the Linux performance and energy efficiency on Milan-X is now with the latest Linux software stack compared to the numbers when Milan-X launched back in March 2022. ⌘ Read more

Google’s Vibe Coding Platform Deletes Entire Drive
A Google Antigravity user says the AI-driven “vibe coding” tool accidentally wiped his entire D: drive while trying to clear a project cache. Google says it’s investigating, but the episode adds to a growing list of AI tools behaving in ways that “would get a junior developer fired,” suggests The Register. From the report: We reached out to the user, a photographer and g … ⌘ Read more

Intel Working On Linux Support For New Power Savings Feature With Xe3P_LPD
The upcoming Linux 6.19 kernel cycle is set to introduce initial support for Xe3P graphics to be found initially with Nova Lake processors. While that initial support is landing for Linux 6.19, other extra Xe3P features are still to be added to the open-source kernel driver over coming release cycles. One of those extra features being currently tackled is a new element with Xe3P_LPD: the ability to use the system cache for FBC… ⌘ Read more
