pub fn init_topology() -> Vec<(u32, u32, u32)>Expand description
Build the seeded rows from the shared Topology view. Uses scx_utils::Topology as the source of truth with a sysfs fallback on fault, so large hosts fold to the machine queue with no panic and no extra scan on the hot paths. Span equals the online list at construction, sorted in rank order with the CPU plus node bounds, so the seed matches sysfs online with no extra view. Sibling follows sibling_cpus with two-way assumed, so extra threads on wider cores stay single with no extra scan.
