[Bugfix][KVConnector] Support DCP/PCP in OffloadingConnector#41549
Merged
Conversation
Multiply OffloadingSpec hash_block_size and gpu_block_size by decode_context_parallel_size * prefill_context_parallel_size to match the logical-unit convention used by Request.block_hashes (and already applied in kv_cache_coordinator, single_type_kv_cache_manager, and kv_cache_utils).
