Struct SiblingPlan 

Source 
pub struct SiblingPlan {
    pub smt_on: bool,
    pub cpu_sibling: [u32; 1024],
    pub cpu_core: [u32; 1024],
}
Expand description

SMT sibling-planning decision, separated from sysfs discovery so the pure logic is unit-testable.

Fields§

§smt_on: bool

True when any online CPU has a sibling sharing its physical core.

§cpu_sibling: [u32; 1024]

Per-CPU: the lowest-id other CPU sharing the core, or the CPU itself when the core is unpaired or the CPU is unknown.

§cpu_core: [u32; 1024]

Per-CPU core id (mlfq_cpu_core rodata), MAX_CPUS sentinel when unknown. The table groups by core_id (not llc_id) and handles

2-way SMT by picking the lowest-id sibling per CPU.
