Enum SampleSkid

pub enum SampleSkid {
    Arbitrary,
    Const,
    ReqZero,
    Zero,
}

Controls the amount of sample skid.

Skid is how many instructions execute between an event of interest happening and the kernel being able to stop and record the event.

Smaller skid is better and allows more accurate reporting of which events correspond to which instructions, but hardware is often limited with how small this can be.

This affects the precision of code_addr.

Variants

Arbitrary

Can have arbitrary skid.

Const

Must have constant skid.

ReqZero

Requested to have 0 skid.

Zero

Must have 0 skid.
