…d per-thread state (#18976) * Squashed commit of the following: commit b3c6bf4 Author: Abhijit Ramesh <abhijitramesh2k@gmail.com> Date: Mon Dec 1 18:29:00 2025 -0800 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. commit 5ca9b5e Author: neha-ha <137219201+neha-ha@users.noreply.github.com> Date: Tue Nov 18 12:17:00 2025 -0800 Refactored pipelines and workgroup calculations (#10) * refactored pipelines * refactored workgroup calculation * removed commented out block of prior maps * Clean up ceiling division pattern --------- Co-authored-by: Neha Abbas <nehaabbas@eduroam-169-233-141-223.ucsc.edu> Co-authored-by: Reese Levine <reeselevine1@gmail.com> Author: James Contini <jamescontini@gmail.com> Date: Wed Oct 29 23:13:06 2025 -0700 formatted embed wgsl and ggml-webgpu.cpp commit e1f6bae Author: James Contini <jamescontini@gmail.com> Date: Wed Oct 29 23:08:37 2025 -0700 implemented REPL_Template support and removed bug in unary operators kernel commit 8c70b8f Author: James Contini <jamescontini@gmail.com> Date: Wed Oct 15 16:14:20 2025 -0700 responded and dealt with PR comments commit f9282c6 Author: James Contini <jamescontini@gmail.com> Date: Sun Oct 12 13:41:41 2025 -0700 removed unnecesarry checking if node->src[1] exists for unary operators commit 4cf28d7 Author: James Contini <jamescontini@gmail.com> Date: Sun Oct 12 13:32:45 2025 -0700 All operators (inlcluding xielu) working commit 74c6add Author: James Contini <jamescontini@gmail.com> Date: Fri Oct 10 13:16:48 2025 -0700 fixed autoconfig commit 3627499 Author: James Contini <jamescontini@gmail.com> Date: Fri Oct 10 13:10:46 2025 -0700 removed vestigial files commit cb08583 Author: James Contini <jamescontini@gmail.com> Date: Fri Oct 10 12:59:32 2025 -0700 abides by editor-config commit 5360e28 Author: James Contini <jamescontini@gmail.com> Date: Fri Oct 10 12:45:57 2025 -0700 rms_norm double declaration bug atoned commit 7b09baa Merge: 8a6ec84 74b8fc1 Author: James Contini <jamescontini@gmail.com> Date: Fri Oct 10 11:50:03 2025 -0700 resolving merge conflicts commit 8a6ec84 Author: James Contini <jamescontini@gmail.com> Date: Wed Oct 8 18:06:47 2025 -0700 unary operators pass ggml tests commit c3ae382 Author: James Contini <jamescontini@gmail.com> Date: Wed Oct 1 16:22:40 2025 -0700 neg passes backend test commit aa1c9b2 Author: James Contini <jamescontini@gmail.com> Date: Tue Sep 30 23:55:27 2025 -0700 neg f16xf32xip builds and runs, havent actually ran a model that uses neg kernel yet though Co-authored-by: James Contini <jamescontini@gmail.com> Co-authored-by: Neha Abbas <neabbas@ucsc.edu> Co-authored-by: Abhijit Ramesh <abhijitramesh2k@gmail.com> * Remove extra code and format * Add ops documentation (finally) * 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 * Move shared state (webgpu_context) and device creation out of registration context, device context, and buffer context, and move into backend context * Small cleanup * Move Instance, Device, Adapter, Device creation, and capabilities to global state while moving Queue, pipelines, and buffers to per-thread state. * Cleanups * More cleanup * Move staging_buf mutex to global context * Resolve merge * Resolve merge * Resolve merge * Clean up merge errors, delete forward declaration, and run clang-format * Rename device_init to backend_init * Move webgpu_context to backend_context * Move buffer context members into global context and refactor function calls * Run clang-format * Remove commends * Move parameter buffers to per-thread, add single memset_tensor param buf * Fix CI compilation issue * Fix builds for emscripten not supporting subgroups * cleanup * cleanup --------- Co-authored-by: Reese Levine <reeselevine1@gmail.com>
* sampling : remove sampling branching in output_reserve This commit updates output_reserve in llama-context.cpp to always allocate sampling buffers regardless of whether sampling is needed for the current batch. The motivation for this is to avoid reallocations and branching based on the sampling requirements of the batch.
* llama : disable Direct IO by default * cont : override mmap if supported
