pub fn pick_largest_llc(sizes: &[u64], nr_llcs: u32) -> Option<u32>Expand description
Pick the LLC domain with the strictly-largest cache size.
The Q1 placement bias needs a single unambiguous winner. With fewer
than two domains, or two or more domains tied for the largest size
(including the all-zeros case of a fully failed discovery), there is
no capacity win to exploit and the feature stays off (None).
sizes is indexed by LLC domain id; only the first nr_llcs
entries are considered.
