Recently with the Arc Pro B70 in having four review samples for testing I was finally able to try out the multi-GP … ⌘ Read more

[$] Scaling transparent huge pages to 1GB
As a general rule, when developers talk about huge pages, they are
referring to PMD-level pages that are 1MB or 2MB in size, depending on the
CPU architecture. Most CPUs can support other huge-page sizes, though. On
x86 systems, PUD-level huge pages hold 1GB of data. Providing such large
pages transparently to processes has generally not been considered as
either feasible or desirable, but Usama Arif is trying to change that
assessment. At the 2026 [Linux Storage,\
