Struct DVFSRaceSource 

pub struct DVFSRaceSource;

Cross-core DVFS race entropy source.

Spawns two threads that race via tight counting loops. The absolute difference in their iteration counts after a short window (~2μs) is physically nondeterministic because:

1. P-cores and E-cores have independent DVFS controllers that adjust frequency based on thermal sensors, power budget, and workload.
2. The scheduler assigns threads to different core clusters nondeterministically based on system-wide load and QoS.
3. Even within a single core type, frequency transitions are asynchronous and thermally-driven — two identical cores can run at different frequencies at the same instant.
4. The stop signal propagation has cache-coherence latency that varies by which cores the threads landed on.

Trait Implementations

impl EntropySource for DVFSRaceSource

fn info(&self) -> &SourceInfo

Source metadata.

fn is_available(&self) -> bool

Check if this source can operate on the current machine.

fn collect(&self, n_samples: usize) -> Vec<u8>

Collect raw entropy samples. Returns a Vec<u8> of up to n_samples bytes.

fn name(&self) -> &'static str

Convenience: name from info.
