Technical Overview
Engineering breakdown of Architecting Linux Kernel Memory Page Allocations (6727). Bare-metal hardware performance requires isolated kernel parameters, precise page allocator tuning, and NUMA-aware placement strategies.
Page Allocator Internals
The Linux kernel's buddy allocator manages free page blocks in power-of-two orders. Understanding struct zone, struct page, and the per-CPU page caches is critical for reducing allocation latency.
NUMA and Memory Policies
Using numactl and mbind allows binding allocations to specific nodes, minimizing remote memory access penalties.
Compaction and Reclaim
Proactive compaction via /proc/sys/vm/compact_memory and tuning vm.min_free_kbytes reduces fragmentation-induced allocation failures.
