Struct Control 

pub struct Control {
    pub stall: u8,
    pub yield_: bool,
    pub wr_barrier: u8,
    pub rd_barrier: u8,
    pub wait_mask: u8,
    pub reuse: u8,
}

The per-instruction control codes — where the GPU’s static scheduling lives.

Fields

stall: u8

Fixed stall before issuing the next instruction (0–15 cycles).

yield_: bool

Yield hint (let another warp issue).

wr_barrier: u8

Write-barrier scoreboard this instruction sets (7 = none) — for variable-latency results.

rd_barrier: u8

Read-barrier scoreboard this instruction sets (7 = none) — for operand-still-in-use.

wait_mask: u8

Which barrier scoreboards this instruction waits on (6-bit mask).

reuse: u8

Operand reuse-cache flags (4 bits) — avoids re-reading the register file.

Implementations

impl Control

pub fn decode(hi: u64) -> Control

Decode the control field out of the high 64-bit word.

pub fn apply(&self, hi: u64) -> u64

Write this control field back into hi, replacing exactly the control bits and leaving the rest intact.

Trait Implementations

impl Clone for Control

fn clone(&self) -> Control

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Control

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Control

fn eq(&self, other: &Control) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Control

impl Eq for Control
