* hexagon: introduce op request batching and rewrite buffer managment
The host now prepares batches of requests and dispatches them via a single dspqueue message.
Buffers are mapped explicitly by NPU while processing batches.
* hex-dma: disable l2 bypass since to work around new issue due to no flushes between Ops
* hex-utils: add explicit l2flush and l2clear helpers
* hex-opreq: use fine-grain per tensor l2 management
* hex-opreq: avoid redundant invalidates for tensors we already flushed
* hex-opreq: update debug messages
* htp-opreq: reuse ops_context
* hex-opreq: do not flush or invalidate cache lines beyond buffer boundry
* hex-opreq: fix errors in log message
* Revert "hex-opreq: do not flush or invalidate cache lines beyond buffer boundry"
This reverts commit 8b7f0a55a750a6430ce4eb1874c7feb3d720056d.
* hexagon: limit l2 flushes to 1MB which covers l2 cache
* hex-opreq: limit cache flush to 4MB
Looks like 4MB cont. vitual space should cover the 1MB cache.
* hexagon: drop cache flush size to 2MB
* hex-opreq: start reworking opreq packing
* hex-opreq: introduce new way of packing opbatch where tensors are stored separately
* hex-opreq: add a simple fastrpc call to force unmap all buffers
* hex-l2flush: somehow 2MB does not seem robust, also cleanup step size to use line-size
* hex-opreq: bump opreq batch size to 256
* hex-mm: place src1 spad at the top of vtcm for easy reuse
* hex-ops: introduce internal types and disable src1 reuse for now
Nothing new just formalizing the repack / qyn.quant types we've been using.
* htp-opreq: use tensor pointers instead of copies
* hex-opreq: introduce more robust way for tracking vtcm/spad reuse
This removes the SKIP_QUANTIZE flag that became fragile with the addition of HMX and other ops.
* hex-cumsum: fix error post opreq merge
* hex-opreq: move request batch handling into the session
Prepping everything for using dspqueue buffers and doing that inside the session is much cleaner.
* hex-mm: yet another fix for src1 reuse when we're mixing hmx/hvx
* hex-bufs: introduce pinned mmapings and use non-pinned ones for model buffers
* hex-buf: add support for allocating shared/pinned buffer for opreqs
* hex-opbatch: make opbatches configurable
* hex-naming: better name for ggml_hexagon_shared_buffer
* hex-naming: add session->c_name() helper
* hex-opbatch: start using shm but still copy for now
* hex-opbatch: use shared buffer for packing opbatch
* hex-opbatch: beter naming for opbatch related classes and code
* hex-opbatch: reuse batched tensors with same data/dims/strides
* hex-opbatch: update logging
* hex-opbatch: add support for vmem limit for op batching
* hex-opbatch: update htp side to properly support dynamic mmap/unmap
* hex-opbatch: add OB and OQ params for run-completion script and fix the asserts in batch processing
* hex-opbatch: fixed src1 handling in act ops
* hex-act: fix empty src1 handling in swiglu and friends
Simplify preamble macro while at it
* hex-mm: minor fix vtcm and dma handling in matmul
cleaning up some left-overs from merges
* hex-opbatch: allocate extra 1KB for dspqueue overhead
* hexagon: fix softmax for non-aligned tensors and cleanup vtcm alloc
* hex-mm: properly handle hmx_disabled flag
* hex-ops: update comments
* hex-ops: add debug output for get/set-rows
* hex-mmap: optimize un/mapping of buffers
* hex-opreq: global cache flush and invalidate beyond 128KB threshold
* hex-ops: add super simple opfilter regex for debugging
If an Op matches the regex hex backend will reject it.
* hex-opbatch: wireup newer ops missed in merge and update main switch to detect this in future
* hexagon: improved vtcm acquision to remove inter-op overhead
Fully compatible with QNN-HTP coex
* hex-mm: fixed hvx fallback path
* hex-mm: lower the vmem threshold a bit further to ~3GB
* hexagon: update debug & error logs
This also fixes an issue with newer llvm merging repack and non-repack
functions. We use those pointer to distinguish between buffer types.
* hexagon: move ops context into main context
Just a cleanup. We don't need separate contexts at this point.
* hex-opbatch: cleanup naming and headers for opbatch and related descriptors
* hex-fa: it's now better to enable FA during TG to reduce graph splits
* hexagon: remove GGML_HEXAGON_EXPERIMENTAL env var
It's no longer useful. Please use more flexible GGML_HEXAGON_OPFILTER to disable Ops
if needed for debugging or validation.
* hexagon: fixed editorconfig check
* Update ggml/src/ggml-hexagon/ggml-hexagon.cpp
