The OpenAI chat completions API specifies content part type "video_url"
with a {"url": ...} object, and clients typically send data: URIs
(e.g. data:video/mp4;base64,...). The llama-server only accepted the
non-standard "input_video" type and rejected data: URIs for video
(accept_base64_uri=false), so any OpenAI-conformant client failed with
"unsupported content[].type" or "Invalid uri format".
- accept "video_url" as an alias of "input_video"
- read the media object from whichever key was used
- allow data: URIs for video (data:video/*), as already done for images
This commit adds a new recipe/target to the Makefile which allows the
logits verification to be run on pre-existing model outputs.
The motivation for this is that for large models it can take a long time
to run them models, and especially for the original model which seldom
changes this is very time consuming. With this change we can run the
original model one which will store the tokens and logits, and then
manually run the converted model and the run use this recipe to verify
them against the orignal model.

- drop the dead LOAD_VEC_A != 8 branch in the IQ4_XS shmem load; iq4_xs is
in lut_load_vec_a()'s "8" list, so that path is never generated
- disable MMVQ for IQ4_XS on Intel (27.3% tg regression on A770)

Since #28732 our internal symbols are exported. A duplicate copy dlopened and
dlclosed by ggml_backend_load_all() then interposes them, so its destructors
destroy the live vk_instance and later device queries hit the GGML_ASSERT on
vk_instance.device_indices. Hidden visibility exports only GGML_BACKEND_API,
as before #28732.
Fixes#29138

Avoid returning references through lambdas that hold a local cast pointer, which triggers -Werror=dangling-reference in some CI compilers. Reuse the precomputed select_expr pointer directly.

* server: route every model load through the queue
A model loaded by the fast path has no queue entry, so tick() evicts
it at its LOADED transition before its own request is proxied. Every
load now joins the queue, whose entry protects the model until its
waiters leave.
* server: do not admit requests into a stopping model
A request for a model that is being stopped still sees it LOADED and
is proxied into the dying child. Such a request now joins the queue
and is served by the next instance. The stopping mark is cleared
under the same lock that sets UNLOADED, so no request can see a
model that is neither stopping nor unloaded while its child is gone.

* model : add DFlash layer-input taps for HunyuanVL
DFlash speculative decoding needs the target graph to expose the residual
stream entering each layer (res->t_layer_inp[il]) - the draft model reads
those tensors to build its cross-context. Qwen3 and the other DFlash-capable
targets register them, but the Hunyuan graphs do not, so serving a DFlash
draft against a HunyuanOCR target aborts during the first graph build:
GGML_ASSERT(t_layer_inp[il] != nullptr && "layer input tensor is null")
Register the tensor at the top of the layer loop, mirroring qwen3. The
layer input is the residual stream entering layer il, i.e. the output of
layer il-1, which is what the draft's target_layers metadata refers to
(the converter writes target_layer_ids+1). hunyuan-dense.cpp reuses this
graph, so it is covered as well; hunyuan-moe has a separate graph and is
untouched.
The vector is only read when a speculative implementation enables those
layer ids, so there is no behaviour change without a draft model.
Tested with tencent/HunyuanOCR 1.5 and its DFlash draft: image requests now
run, draft acceptance is ~0.5 and the OCR output is byte-identical to the
non-speculative run.

* convert : fix DFlash draft conversion against HunYuan targets
Converting a DFlash draft with a HunYuan target failed in two ways.
1. DFlashModel.set_vocab() reuses the target class' vocab handling by
calling it unbound with the draft instance, but HunYuanModel.set_vocab()
called self._fix_special_tokens(), a method that only exists on
HunYuanModel, so the conversion always aborted with
AttributeError: 'DFlashModel' object has no attribute '_fix_special_tokens'
Make the vocab helpers module-level functions taking the model
explicitly, so they do not depend on the instance being a HunYuanModel.
They have no other callers, so the two id lookups are folded into
_fix_special_tokens().
2. The delegated call runs with self.dir_model pointed at the target but
keeps the draft's self.hparams, so config lookups inside the target's
vocab code (the pad_token_id < 0 guard, eod_token_id) read the draft's
config instead of the target's. That aborts on targets with
pad_token_id = -1 (e.g. the HunyuanOCR v1.0 checkpoint) and otherwise
writes special token ids that disagree with the target.
Add _vocab_hparams(): it returns the target's config (with text_config
merged to the root, as TextModel does) when the model is a draft
converted with --target-model-dir, and the model's own hparams
otherwise, so a normal conversion is unaffected.
Tested: converting tencent/HunyuanOCR/dflash succeeds with both the 1.5 and
the v1.0 target; converting the base model without --target-model-dir
produces a byte-identical GGUF to before.

The snapdragon CI builds packages only to feed the QDC device tests, so
Hexagon NPU binaries never reached the releases page. Build both targets
in release.yml and attach them as release assets.
This commit tweaks the Toaster element to include a close button.
These toasts often cover other UI elements like the model selector, and
this change avoids having to wait for them to disappear on their own
(e.g. after a load failure).

The 5-argument load_ldmatrix added in 1884824fd only defines tile<16,8>, so the Volta tile<8,4> does not match. See https://github.com/ggml-org/llama.cpp/issues/29222 for details. Building on 1884824fd, generalize the tile shape of the 5-argument load_ldmatrix from <16,8> to <I,J>, so the non-swizzle branch forwards to the 3-argument loader for any shape. Local compilation and testing passed.

convert_unary handles the contiguous case through the general strided kernel,
one element per thread: each lane reads 4 bytes and writes 2. Converting the
activations for a bf16 matrix multiplication that way moves 126 MB in 1021 us
on gfx1151, about 65% of what the memory system can do.
Give the contiguous path its own kernel that takes four elements per thread
through a vector type, so a warp loads 512 bytes at a time instead of 128. It
is used only when the element count is a multiple of four and both pointers
carry the alignment the vector type needs, and falls back to the strided
kernel otherwise.
Model level, Qwen3.8-Next-Flash IQ3_XXS on gfx1151, llama-bench -ub 2048 -r 6,
mean of the last 3 reps, ABBA counterbalanced:
pp2048 688.0 680.0 -> 694.3 691.1 +1.26%
tg128 24.8 24.8 -> 24.8 24.8 +0.14%
Every conversion in a prefill takes the new kernel (kernel trace: 1146
convert_unary_cont_vec4, no convert_unary). Output is bit identical; MUL_MAT,
MUL_MAT_ID, CPY, CONT, GET_ROWS and SET_ROWS pass.
