class max.nn.kv_cache.MLAAttnKey(batch_size, max_prompt_length, num_partitions)

source

pack_into_buffer()

pack_into_buffer(device, max_cache_valid_length)

source

Packs this key into a kernel dispatch-metadata buffer.

max_cache_valid_length is the runtime cache length; it is supplied here rather than stored on the key so the key’s identity is independent of it.

• max_cache_valid_length (int)

Return type:

Buffer
