* hex-dma: make chained dma the default to handle newer models
This also includes some new instrumentation that we can remove later.
* hexagon: add uint32 dump helper
* hexagon: use single-page VTCM allocation to avoid issues with large gather ops in ssm-conv
ssm-conv uses HVX gather instruction and that instruction cannot handle cases where the base+offset
spans page boundaries.
* hexagon: update ssm-conv to make base-addr compute a bit easier to read
* hex-dma: use 1d mode for reshaping, it supports sizes up to 24-bits (>16MB)
* hex-bin: fix incorrect stride logic
* hexagon: make sure repack buffs are dumped for verbose > 2
* hex-bin: consistently use dma_queue_push even for dummy dst transactions
* hex-dma: start using 2d-wide mode on v75 and up
The removes the need to deal with the 16-bit limitaion for the strides.
* hex-bin: cleanup kernel selection logic
* hex-bin: cleanup binary op core and fix transposed tensor handling
* snapdragon: update run-bench to use larger ubatch and fa-on
* Fix music generation token stopping for quantized models
In Phase 1 lyrics mode, the FSM transitions to CODES state after
TOKEN_THINK_END and disables itself. The quantized Q4_K_M model was
not efficiently generating TOKEN_IM_END to stop the generation,
causing it to continue until hitting the 8192 token limit.
This fix forces TOKEN_IM_END to be generated immediately after
TOKEN_THINK_END in lyrics mode, ensuring clean completion of the
planning phase without excessive token generation.
Testing shows generation now completes in ~500ms instead of 80+
seconds with timeout errors.

* Improve fix: only force TOKEN_IM_END at token limit
Instead of forcing TOKEN_IM_END immediately after TOKEN_THINK_END,
only force it when we've reached the token limit. This allows the model
to generate lyrics after the thinking block while still preventing KV
cache exhaustion.

ACL graph capture disallows host-to-device memcpy and device memory
malloc/free on the captured stream. Pre-load the RoPE cache before
capture so that:
- Host-to-device copies and allocations run on the non-captured stream
- Cache metadata is populated and memory pool is warmed up
- During capture, only on-device computations are recorded; host-side
and allocation branches are skipped

* Increase per-thread work if the K-dimension is small
With tensor parallelism, the K-dimension of the FFN-down matrices is split, which makes it quite small, especially for MOEs. For example, Qwen3-30b-A3B has a K-dimension of 768, and Qwen3235B-A22B has k-dimension of 1536.
The current heuristic uses a group of 4 warps irrespective of K-dimension size, resulting in some of the threads being idle. This results in poor performance for these matrices.
This change increases the number of output elements per block for such cases.
* Limit this change to ncols_dst = 1
* tab to space

Prefer referring to known-good quantizations under ggml-org rather than

* grammar: prevent stack overflow with nullable symbol loop
Fix a potential stack overflow in llama_grammar_advance_stack that
could occur when processing grammars with nullable symbols that lead
to infinite derivations of empty strings. The fix introduces cycle
detection by tracking visited stacks to prevent infinite recursion.

v2: Added a `std::set` to perform tree-based lookups with O(N log N)
complexity. Testing with a parallel run of `test-grammar-integration`
shows a double-digit percentage increase in runtime. An
`unordered_set` with O(1) hashing was also evaluated, but the overhead
of constructing hash keys from pointers made it significantly slower
than the rbtree implementation that only requires an ordering
operator. The performance regression in the test suite appears
justified by the overall reduction in algorithmic complexity.

* grammar: add test case for hang in repetition grammar processing
This commit adds a new test case to the grammar integration tests that
specifically targets a hang scenario in the repetition grammar parser
found while adding GBNF support to ripgrep-edit.

-d '{

* grammar: add repetition threshold check
The change introduces a maximum repetition threshold to avoid
excessive rule expansion during grammar parsing. When parsing
repetition patterns like {m,n}, the parser now calculates the
potential number of rules that would be generated and throws an error
if the product of previous rules and new rules exceeds the threshold.
A test case was added to verify the threshold is properly enforced for
deeply nested repetition patterns that would otherwise cause hangs.
The MEAN/CLS/LAST pooling paths in encode() and decode() used
n_embd_inp() (16384 for qwen3vl with deepstack) to read from the
pooled embedding tensor, which only has n_embd_out() (4096) floats
per sequence. This caused a tensor read out of bounds assertion.
Fixes embedding mode for Qwen3-VL-Embedding models.
