ggml webgpu: support for backend sampling (#18880)
* ggml webgpu: add SOFTPLUS unary operator Implements SOFTPLUS (log(1 + exp(x))) with f16/f32 support. Uses f32 precision for intermediate calculations to prevent f16 overflow. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * Follow Vulkan backend numerical stability pattern * ggml webgpu: add EXPM1 unary operator Implements EXPM1 (exp(x) - 1) with f16/f32 support. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * ggml webgpu: add FLOOR unary operator Implements FLOOR (rounds down to nearest integer) with f16/f32 support. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * ggml webgpu: add CEIL unary operator Implements CEIL (rounds up to nearest integer) with f16/f32 support. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * ggml webgpu: add ROUND unary operator Implements ROUND (rounds to nearest integer) with f16/f32 support. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * ggml webgpu: add TRUNC unary operator Implements TRUNC (truncates towards zero) with f16/f32 support. * Add shader implementation and 4 variants (f32/f16, inplace/non-inplace) * Register pipelines and device support * docs : update WebGPU support for unary operators (FLOOR, CEIL, ROUND, TRUNC, EXPM1, SOFTPLUS) * Updates to webgpu get_memory * Add argmax * Add argmax,cumsum,sum,sum_rows * Add necessary CPY/GET_ROWS operators * Support for argsort using multi-pass strategy * Update set_rows for i32 indices, move to pre-wgsl * Port unary operators to pre-wgsl and support FILL * Implement PAD * Add support for top-k * clean up, scope pipeline init mutex * fix newline * Add support for log * Update LOG for better precision, and ops doc --------- Co-authored-by: Abhijit Ramesh <abhijitramesh2k@gmail.com> |

ggml webgpu: add CEIL operation support (#18605)
* ggml-webgpu: add CEIL operation support
Add support for the CEIL unary operation in the WebGPU backend:
- Add CEIL_FUNC shader template in unary_op.wgsl
- Add 4 shader variants (f32, f16, inplace versions)
- Initialize CEIL pipelines in ggml-webgpu.cpp
- Register CEIL in supports_op function
* docs: update WebGPU ops support for CEIL

ggml webgpu: fix xielu parameter passing (#11)
The XIELU operation was incorrectly using static_cast to convert
float parameters to uint32_t, which converted numeric values instead
of preserving IEEE 754 bit patterns. This caused incorrect values
to be interpreted by the GPU shader.
* Use reinterpret_cast to preserve float bit patterns when passing
through uint32_t params buffer
* Update WGSL shader parameter types from u32 to f32
* Re-enable XIELU support (was disabled due to numerical issues)
Fixes NMSE test failures for XIELU operation on WebGPU backend.
