* CUDA indexer topk: this is better for PP
* Don't overstep
* Cleanup
* Allow Q8_0 cache in the CUDA DSA implementation
* DS4: do not cast caches to f32
* DS4 optimizations (part 2)
* This is slightly better
* Another minor tweak
* Increase max. number of graph splitinputs to 64
Else with DS4 we can trun into an assert for specific offload
situations with more than one GPU.
* Adding ds4_comp op with CPU implementation
* ds4_comp on CUDA
* ds4_comp: ratio = 4 specialization
Surprisingly small performance gain
* Also handle HCA via ds4_comp
But much smaller gain, if any.
* Delete commented out stuff
* Remove the [(size_t) il] noise
* Minor
* Fix quantized cache
* initial map to load deepseek 4 arch
* wip
* wip: match graph build and attn logic for dpv4
* wip: Enhance DeepSeek-V4 architecture with new tensor types and sqrtsoftplus gating function
* Update DeepSeek-V4 to support raw key indexing with read/write indices
* fix mismatch in attn_raw
* Enable FA with CSA/HCA
* Fix logit mismatch with FA path
* Clean traces and logs for debug
* Refactor DSV4 tensor handling for MTP execution and improve raw context management
* Refactor DeepSeek4 tensor operations: replace manual weighted sum and post-processing with new helper functions
* Share mHC pre-projection and fix packed DSV4 writes
* DSV4: add shared top-k selection and improve mask handling
* Fix DSV4 c2048 view stride and duplicate loader instantiation
* Reuse shared RMS normalization in DSV4 graph
* Replace DSV4 indexer rotation with shared Hadamard
* Share CSA visibility mask with DSV4 LID
* dsv4: document dependency ordering and reset state
* Remove DSV4 zero-dependency graph shim
* Fix DSV4 packed stream execution
* Remove DSV4 l_out backend override
* Enable DSV4 quantized K-only cache
* Revert "Enable DSV4 quantized K-only cache"
This reverts commit 04f9b425321f62ba60e16d1bea2f8de714cfe855.
* Fix DSV4 quantized cache accounting
* Fail closed on unsupported DSV4 cache lifecycle operations
* Various optimizations
* llama: fix GGML_METAL=ON build - missing ggml-metal.h include in llama-dflash.cpp (#2134)
llama-dflash.cpp calls ggml_backend_is_metal() and
ggml_backend_metal_set_n_cb() inside an #ifdef GGML_USE_METAL block but
never includes ggml-metal.h, so any Metal-enabled build fails to
compile. Add the same guarded include llama.cpp already uses.
* New op: ggml_sum_rows_ext (#2132)
* Add ggml_sum_rows_ext
* openPangu: use ggml_sum_rows_ext also in mhc_post
* openPangu: use ggml_sum_rows_ext also in mhc_tail
* Minor
* Reuse shared inverse RoPE operation for DSV4
* Reuse maintainer CUDA concat implementation
* WIP
* hc_pre
* hc_post
* Remove unnecessary mask manipulations
* WIP
* Take into account swiglu limits
* Turn on fused indexer by default
* Give names to mat mul results
* More named ops
* dsv4: do not uselessly copy the KV cache
+20% TG at 32k tokens
* mask_to_index and make CPU FA work with that
* Much better CPU-only, CUDA still not functional
* Better CPU TG
I'm now at 9.7 t/s for zero context and 6.5 t/s for context of 32k.
PP is 120 t/s for short context and 101 t/s at 32k.
* Even better CPU TG
I'm now at 8.1 t/s for context of 32k tokens.
* Turn off DSA on CUDA for now
* Fix CUDA DSA
* Remove again the unnecessary softmax result buffer
* Experiments
* Various
* More named ops
* Forgot to uncomment
