Struct GSPGPU_PerfLogEntry

#[repr(C)]
pub struct GSPGPU_PerfLogEntry {
    pub lastDurationUs: u32_,
    pub totalDurationUs: u32_,
}

GSPGPU performance log entry.

Use the lastDurationUs field when benchmarking single GPU operations, this is usally meant for 3D library writers.

Use the difference between two totalDurationUs when using a GPU library (e.g. citro3d), as there can be multiple GPU operations (e.g. P3D, PPF) per render pass, or per frame, and so on. Don’t use totalDurationUs as-is (rather, take the difference as just described), because it can overflow.

Fields

lastDurationUs: u32_

< Duration of the last corresponding PICA200 operation (time between op is started and IRQ is received).

totalDurationUs: u32_

< Sum of lastDurationUs for the corresponding PICA200 operation. Can overflow.
