 #       Remove this patch if upstream provides an official NPU graph-capture

-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#   1. `vllm.v1.kv_cache_interface.MLAAttentionSpec`
-#    Why:
-#       The default `MLAAttentionSpec` is mainly built around `kv_lora_rank`
-#       and `qk_rope_head_dim`. On NPU, we also use this class to describe DSA
-#       models. Unlike the GPU path, where cache management is handled by an
-#       additional indexer module, extending this class directly simplifies the
-#       corresponding `model_runner` implementation on NPU.
-#
-#       This patch also adds Sparse C8 support for DSA models on NPU. As part
-#       of that support, members such as `page_size_bytes` need to be adapted,
-#       so they are overridden here as well to preserve overall readability.
-#    How:
-#       This patch subclasses the original implementation, overrides selected
-#       methods, and adds DSA-specific attributes and helpers with default
-#       values where needed.
-#    Related PR (if no, explain why):
-#       https://github.com/vllm-project/vllm/pull/25896
-#    Future Plan:
-#       Remove this patch after the upcoming KV cache spec refactor.
