Struct ChunkedPrefillPageMetadata

pub struct ChunkedPrefillPageMetadata {
    pub block_table: DevicePtr,
    pub seq_len: DevicePtr,
    pub block_capacity: usize,
    pub uploaded_blocks: usize,
}

Expand description

2026-09-25: Per-sequence device copies of the paged-attention metadata for chunked prefill, kept across chunks so each chunk uploads only the block-table entries it added.

Fields§

§block_table: DevicePtr

2026-09-25: The block table as 32-bit entries.

§seq_len: DevicePtr

2026-09-25: The running sequence length, one u32.

§block_capacity: usize

2026-09-25: Block-table entries allocated, sized for the whole prompt.

§uploaded_blocks: usize

2026-09-25: Block-table entries already uploaded.
