LWN.net | All | [$] Toward better handling of major page faults |
May 23, 2026 6:40 AM * |
||
A major page fault occurs when a process attempts to access a page that is not currently present in RAM; satisfying such faults usually involves I/O, and can thus take some time. When many threads sharing an address space are generating page faults, the result can be significant lock contention while that I/O takes place. During the memory-management track at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Barry Song led a session to try, yet again, to find an enduring solution to this problem. https://lwn.net/Articles/1073071/ --- SBBSecho 3.37-Linux * Origin: Palantir * palantirbbs.ddns.net * Pensacola, FL * (618:250/24) |
