The llama.cpp project released build b10655, which introduces support for the LIGHTNING_INDEXER operation within the Vulkan backend to enable Deepseek V4 operations.
- Added the LIGHTNING_INDEXer op to the Vulkan backend.
- Updated lightning_indexer.comp and ggml-vulkan.cpp to move 128-lane dot-product reduction from a shared-memory tree to subgroupAdd.
- Included cleanup changes such as skipping bounds checks and reverting previous FA_K_ONLY modifications.
- Restored interleaved K/V buffer ordering and removed FA_K_ONLY logic.
This update provides Vulkan users with the capability to run Deepseek V4 operations using the new LIGHTNING_INDEXER implementation.
