It is common, on NUMA systems, to try to allocate all memory on the local node, since it will be the fastest. That is not the only possible policy, though; another is weighted interleaving, which seeks to distribute allocations across memory ...

BPF is, famously, not part of the kernel's promises of user-space stability. New kernels can and do break existing BPF programs; the BPF developers try to fix unintentional regressions as they happen, but the whole thing can be something of a bumpy ...

Knowing how frequently accessed a page of memory is (its "hotness") is a key input to many memory-management heuristics. Jonathan Cameron, in a memory-management track at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, pointed ...

Eduard Zingerman presented a daring proposal that "makes sense if you think about it a bit" at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit. He wants to inline performance-sensitive kernel functions into the BPF programs that ...

Compute Express Link (CXL) memory is not like the ordinary RAM that one might install into a computer; it can come and go at any time and is often not present when the kernel is booting. That complicates the management of this memory. During the ...
