[$] Scaling transparent huge pages to 1GB

As a general rule, when developers talk about huge pages, they arereferring to PMD-level pages that are 1MB or 2MB in size, depending on theCPU architecture. Most CPUs can support other huge-page sizes, though. Onx86 systems, PUD-level huge pages hold 1GB of data. Providing such largepages transparently to processes has generally not been considered aseither feasible or desirable, but Usama Arif is trying to change thatassessment. At the 2026 Linux Storage,Filesystem, Memory Management, and BPF Summit, he led a session in thememory-management track on how to make transparent huge pages (THPs) trulyhuge.
