Function dispatch_repeat_tiled_f32 

pub fn dispatch_repeat_tiled_f32(
    encoder: &mut CommandEncoder,
    registry: &mut KernelRegistry,
    device: &DeviceRef,
    src: &MlxBuffer,
    dst: &MlxBuffer,
    params: &RepeatTiledParams,
) -> Result<()>

Dispatch a tiled-GQA broadcast on the GPU.

Expands a [seq, hg, k] f32 input to a [seq, h, k] f32 output via dst[t, h, k] = src[t, h % hg, k] in a single dispatch — no compute, no host round-trip.

Arguments

• encoder - Command encoder to record the dispatch into.
• registry - Kernel registry (repeat_tiled_f32 is auto-registered).
• device - Metal device for pipeline compilation.
• src - Input buffer, f32, contiguous, ≥ seq*hg*k elements.
• dst - Output buffer, f32, contiguous, ≥ seq*h*k elements.
• params - Shape parameters.

Errors

Returns MlxError::InvalidArgument if any dimension is zero, if h % hg != 0, or if either buffer is too small for the declared shapes.
