This allows vec4 loads of the B elements. Also increase BK to 64 when this is
enabled. Neither of these alone is consistently faster, but together these give
a nice speedup.
In ggml-vulkan.cpp, we need to make sure the B matrix alignment and stride are
multiples of 4.
* cuda: reset device in get_memory function if no backend is active
* also count device and host buffers
* exclude hip and musa from counting and device reset
* use device mutex instead of atomic
* undo backend_free function move
* common : relax sampler name matching
Currently, in some cases, the alternative names for samplers (like
`top-k` and `min-p` instead of the canonical `top_k` and `min_p`) are
not always recognized by the `common_sampler_types_from_names` function
in `common/sampling.cpp`.
This PR changes the signature of this function to remove the `bool
allow_alt_names` flag, and removes all occurences of the flag from call
sites. Therefore, the function will now always match all known names.
I also changed the logic of the function to unconditionally check the
provided sampler names against both the canonical and alternative names,
and to be case-insensitive.
This fixes an issue I was seeing wherein samplers specified in the
`llama-server` UI were not recognized as valid when the alternative
names were used.
* add more alt names
* cont. fix
* cast to unsigned char for correctness
* common : unify sampler name mapping
* annotate canonical vs. alt sampler name mappings per @CISC
* Update common/sampling.cpp

Mistral explicitly sets `moe` and `llama_4_scaling` to `null` in
params.json, breaking `key in dict` checks during conversion. Replace
with `dict.get(key) is not None` where this matters.
Fixes `convert-hf-to-gguf.py --mistral-format Mistral-Medium-3.5-128B`
A fitted target context can end up smaller than the draft default, the
oversized assistant views then overflow the shared K/V tensors and trip
the ggml_view_4d size assert during graph reserve.
