Jesse LaRose 82fce65d8b server : move chat-template thinking probe inside the init try/catch (#24093)
A model whose chat template parses at init but fails parser generation
at apply time (e.g. uses {% call %}) throws std::invalid_argument from
common_chat_templates_support_enable_thinking(), which ran outside the
try/catch guarding common_chat_templates_init(). The throw was uncaught
and llama-cli aborted (SIGABRT) instead of failing to load. Moved the
probe inside that try/catch so an apply-time error fails load the same
way an init parse error does.

RapidMark ccb0c34223 ggml-hip: enable -funsafe-math-optimizations (#24668)
CUDA is compiled with fast math and AMD/HIP is not — this flag lets AMD use fast math too.

We can't use -ffast-math: it implies -ffinite-math-only, which won't compile (ggml uses INFINITY for masking) and produces NaNs. -funsafe-math-optimizations gives the speedup without the NaN problems.

Pascal 2021515a1a cuda: align snake fusion matcher with the other backends (#25460)
* cuda: fix snake fusion type predicate, a and inv_b are F32

The matcher required a->type == x->type while launch_snake reads both
as const float *, matching the CPU and Metal contract where a and inv_b
stay F32. F16/BF16 chains never fused and fell back to the naive path,
and a hypothetical all F16 chain would have read F16 bits as float.
Aligns the predicate and the comment with ggml-cpu.c

* cuda: reject snake fusion on non-contiguous operands

The kernel reads x[idx] and a[c] / inv_b[c] linearly, so a
non-contiguous view passing the matcher would silently read wrong data.
Mirror the contiguity guard already present in the CPU, Vulkan and
Metal matchers.

Hongqiang Wang 92366df30d opencl: Q6_K GEMM/GEMV fix for ne01 of weights that are not multiples of 128. (#25464)
* opencl: fix garbled output for Q6_K weights with ne01 % 128 != 0 on Adreno

Observed with granite-3.1-3b-a800m-instruct, whose vocab is an odd number.

Route Q6_K dense mul_mat with ne01 % 128 != 0 off the noshuffle path:
decode (ne1==1) uses the correct flat GEMV and the matching GEMM (ne1>1)
falls back to CPU (the flat convert has no verified small-batch GEMM kernel
for these shapes). All standard hidden/FFN/vocab dims are multiples of 128
and keep the noshuffle path.

* opencl: reserve alignment slack for the SOA subbuffer carve in alloc size

set_tensor carves quantized weights into per-component subbuffers (d/q,
ql/qh/s/d, ...) whose origins are each rounded up to the device base
address alignment. When a component's size is not a multiple of the
alignment, the carve extends past ggml_nbytes(tensor) and the last
subbuffer overlaps the next tensor in the pool -- e.g. q6_K [1536, 49155]:
size_s = 49155*96 ends 32 bytes past a 128-byte boundary, so the d
subbuffer ends 96 bytes past the tensor's allocation, and whichever of the
two neighboring tensors is uploaded last silently corrupts the other (here:
the last vocab rows' block scales). This affects any quant type whose
component sizes can be misaligned, on any shape with ne01 not a multiple of
the alignment granularity; standard power-of-two dims are unaffected.

Implement get_alloc_size for the OpenCL buffer type and reserve the
worst-case carve slack (4 aligned gaps; 5 components max, q5_K) for
quantized tensors. Costs at most 512 bytes per quantized tensor at the
observed 128-byte alignment.

* opencl: use lm based q6_k mm when ne1 is not multiple of 128

Hongqiang Wang 167d057604 opencl: ragged-tile MoE prefill FP16 GEMM optimization (skip padded expert tiles) (#25433)
* opencl: ragged-tile MoE prefill GEMM (skip padded expert tiles)

The MoE prefill GEMM groups tokens into TILESIZE_N=32 per-expert tiles; at low
tokens-per-expert most tiles are mostly padding. When a tile's upper 16 slots
are all padding (router index 0xFFFFFFFF), skip the second dotx16_reduce8 half.
Numerically identical (skipped lanes are padding). Applied to all eight *_f32_ns
MoE GEMMs; default on, opt out with GGML_OPENCL_MOE_RAGGED_FP16=0.

* opencl: quarter-granularity ragged MoE tile-skip (8-col skip-groups)

Replace the two half-tile dotx16_reduce8 calls in the 8 *_f32_ns MoE GEMMs with
four dotx8_reduce4 (8-column) calls, skipping each empty trailing skip-group
independently. Padding is always trailing, so the kernel rounds the valid count
up to the skip granularity and skips fully-padding groups. Byte-identical to the
non-skipped path. New env GGML_OPENCL_MOE_RAGGED_GRAN={8,16,32} (quarter/half/
off); default quarter.

* opencl: move ragged moe env var in cl_init

Pascal bbebeec4a8 server-stream: follow-up on SSE Replay Buffer (#23226) (#25047)
* server-stream : pimpl

* server-stream: prefix free functions with server_stream_

address review from ggerganov: scope the public stream functions under the
server_stream_ prefix, matching server_stream_session_manager_start/stop.

* server-stream: guard session and manager state with the mutex

address review from ggerganov: make done, completed_ts and the GC running flag plain members under their
mutex and set the condvar predicates under the lock. keep cancelled atomic for
the lock-free should_stop poll.

* server-stream: trim comments to the non-obvious

address review from ggerganov: drop comments that restate the code, keep the
concurrency, lifetime and ordering rationale. de-stale a few comments left by the
pimpl: g_stream_sessions is now internal and the /v1/streams listing is gone.

* server-stream: update dev docs for the pimpl and prefix

reflect server_stream_session_manager_start/stop and the server_stream_ prefix,
note the manager is now a file-static singleton hidden in the .cpp

* server-stream: move stream traces to debug level

keep the bring-up traces for diagnostics but off the default log: skip
drain, draining, drain ended, DELETE evict, attach_pipe, and the router
stream resume proxy.

* server-stream: align router stream resume proxy trace with upstream

the child-side bring-up traces are already SRV_TRC on master, move the
router stream resume proxy trace to the same level.

* server-stream: move stream_read_status enum to the cpp

it is only used by the hidden session and consumer types, so it belongs
with them behind the pimpl boundary, not on the public header surface.

Aleksander Grygier f1161b15f2 ui: Context usage gauge and panel (#25340)
* feat: WIP

* feat: Retire ChatScreenProcessingInfo component, context, and keepStatsVisible settings

* feat: Always-on gauge with active-model /props, conversation stats and live-reactive reading/output/avg

* feat: Add /tokenize endpoint, TokenizeService, FNV-1a and JSON Schema utilities

* feat: Surface enabled-tools token count in context hover card

* refactor(tools): make toolsStore the sole owner of the OpenAI wire format

Previously mcpStore.getToolDefinitionsForLLM() owned the MCP->OpenAI
shape conversion (plus normalizeSchemaProperties). That created two
sources of truth for what gets sent to the LLM, with the
duplication-prone risk of the deduplicated enabled list (which feeds
the token-count cache) drifting from the bytes actually shipped on
chat.

Now:
- mcpStore: pure protocol state + routing. Drop getToolDefinitionsForLLM
  and the inline OpenAIToolDefinition conversion + normalizeSchemaProperties.
  Doc comment adjusted to declare wire-format ownership as belonging
  to toolsStore. Connection lifecycle, health checks, executeTool,
  and the connections/toolsIndex remain.
- toolsStore: owns the wire shape (added earlier this series). mcpEntries()
  inlines the MCP tool conversion; uses normalizeJsonSchema (the JSON
  Schema util extracted in the prior commit) so missing 'type' fields
  are inferred from defaults. mcpTools getter iterates mcpEntries() so
  the Settings UI and the deduplicated enabled list see the same
  definitions. getEnabledToolsForLLM iterates mcpEntries() instead of
  calling mcpStore, so the JSON sent to the LLM is identical to what
  toolsStore.refreshEnabledToolsTokenCount tokenizes.
- agentic: the chat-completion tools field's type was annotated as
  ReturnType<typeof mcpStore.getToolDefinitionsForLLM>, claiming the
  shape was owned by mcpStore. Switch to ReturnType<typeof
  toolsStore.getEnabledToolsForLLM>, the actual source.

* Add tests for the added fusion ops

* Cleanup test-backend-ops

* Cleanup ggml-cuda/mmvq

1. Unrestrict post-scale fusion
2. Rename names accordingly
3. Remove env variable to disable fusion

* Merge old mul_mat patterns into the lane-based approach

* Enable fusion for MoE in shared MMVQ

* Restrict scale_view_nodes, enroll MM + ADD into lane-matcher

* Refactor mmvq loads, still does not help non-nvfp4 kernels

* Restrict scale-fusion to NVFP4

This is necessary, as the prolog is quite heavy in GEMV for some
quants/model configs, leading to net perf regression.
We should really be looking to refactor this such that ratio of
prologue/hot-loop/epilogue is better on the hot-loop
front:

* Allow views to weights in ggml_can_fuse_subgraph

* Remove gate_first from test_mul_mat_vec_fusion

* Ditch lane-parsing approach in favor of hard-coded patterns

* Apply suggestions from code review

Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>

* Rename ggml_is_constant_view_src to ggml_is_constant

* Finish renaming of 0905129e9d

* Readd descriptive prints for fusion debugging

* Add weight-buffer pre-allocation to `test_case`

This is required so we correctly test fusion of NVFP4.

* Update ggml/src/ggml.c

Co-authored-by: Johannes Gäßler <johannesg@5d6.de>

* Add 2nd context for weights as suggested by @JohannesGaessler

This reflects more natural use of ggml compared to artifically
pre-allocating weights into the same context

* Exclude fused tests from gradient mode

I'm unsure of the current state, but naively every fusion pattern
should require its own backpropagation implementation. I don't see these
implemented for the CUDA backend, so we can disable tests to avoid
triggering GGML_ASSERT for

    ggml_tensor * build_graph(ggml_context * ctx) override {
        GGML_ASSERT(!use_weight_context());
        return build_graph(ctx, nullptr);
    }

* Apply suggestions from code review

Thiago Padilha 6c487e2f79 server: enforce prompt cache RAM limit (#25070)
Before this commit, --cache-ram was not a hard limit:

- The cache always kept at least one entry, even if that entry exceeded the
  RAM/token limits.
- Old entries were only evicted for the RAM/token limits after saving the new
  one, which could cause the cache to temporarily exceed the RAM/token limits
  even if individual entries were below the limit.

Now, ensure that the RAM limit is strict with these changes:

- Skip saving state to cache if by itself it exceeds the RAM limit.
- Evict old entries as necessary to make the new entry fit.

Additionally, token-limit cleanup may now evict the last remaining cache entry
instead of always preserving one.
