Published on April 11, 2026, Linux kernel documentation explains detecting and handling bus locks on x86, including the role of split lock operations.
Linux kernel documentation covers how to detect and handle bus locks on the x86 architecture. It describes a split lock as an atomic operation spanning two cache lines that can trigger a bus lock.
The material notes that split locks can affect system performance, making their relationship to atomic operations and memory alignment relevant. Consult the original Linux kernel documentation and verify its detection and handling details before applying changes; the supplied record does not specify concrete options or procedures.
