3 people	b1be68e8ca	[SYCL] Fix Q8_0 reorder: garbage on 2nd prompt + crash on full VRAM (#21638) ... * [SYCL] Fix Q8_0 reorder: add missing dequantize path for GEMM The Q8_0 reorder optimization (#21527) was missing a reorder-aware dequantizer for the GEMM code path used during prompt processing. After token generation reordered Q8_0 weights (via DMMV/MMVQ), the next prompt processing pass would read them with the standard dequantizer, producing garbage output. Add dequantize_block_q8_0_reorder() and wire it into both ggml_get_to_fp16_sycl() and ggml_get_to_fp32_sycl(), matching the pattern already used by Q4_0, Q4_K, and Q6_K. Fixes #21589 AI (Claude) was used to assist with root cause investigation and writing the kernel code. All code was human-reviewed and tested on real hardware. * SYCL: fix reorder crash when device memory is full The reorder optimization allocates a temporary buffer the full size of the weight tensor on the device. When VRAM is nearly full (large models on a single GPU), this allocation fails and the subsequent memcpy crashes on a NULL pointer. Fix: try device allocation first, fall back to host memory if device memory is full. The reorder kernel still works correctly reading from host memory over PCIe. This is slower for the one-time reorder (~21 t/s vs ~38 t/s on Intel Arc Pro B70), but the optimization is preserved for all subsequent inference. If both device and host allocation fail, skip the reorder and fall back to the unoptimized kernel path. Also fixes a bug where opt_for_reorder() marked tensors as reordered even when the reorder was skipped due to allocation failure. This caused DMMV/MMVQ kernels to read the original AoS data as if it were SoA, producing garbage output or NaN results. Tested on Intel Arc Pro B70 (32GB) with Q8_0, Q4_K_M models. Coding was AI-assisted (Claude), reviewed and tested on hardware by a human. Fixes #20478 * SYCL: add RAII temp buffer class + macro guard for host fallback Replace sycl_ext_malloc_with_fallback/sycl_ext_free_fallback free functions with sycl_reorder_temp_buffer RAII class. The host_fallback bool is now a private member, and cleanup happens automatically at scope exit. Add GGML_SYCL_HOST_MEM_FALLBACK cmake option (default ON) to guard the host memory fallback code path. Device access to host memory requires Linux kernel 6.8+ (Ubuntu 26.04+); users on older kernels can set -DGGML_SYCL_HOST_MEM_FALLBACK=OFF to disable it. Addresses arthw's review on PR #21638.

When the DMMV path encountered reordered data it would abort. Add DMMV kernels that read from the SOA reorder layout for both types. Same math as the non-reorder versions, different memory access pattern.

Berk IdemandGitHub	56666fa607	common: skip reasoning budget sampler when no budget is requested (#21870) ... * common: skip reasoning budget sampler when no budget is requested After I added thinking_start_tag / thinking_end_tag for gemma4 in #21697, the reasoning budget sampler gets unconditionally created even when no budget is configured (the default -1). The same applies to kimi_k2, lfm2, lfm2_5, and ministral_3 which also set these tags. The budget gets converted to INT_MAX, so the sampler never actually forces any tokens but still runs per-token checks (start tag matching in IDLE state, token-to-piece conversion + UTF-8 checks in COUNTING state). More importantly, the mere existence of the sampler (non-null rbudget) disables backend sampling. Backend sampling lets the GPU select tokens directly, avoiding a full logits transfer from GPU to CPU every token. This could explain the 30% speed regression reported in #21784 (98 t/s to 70 t/s on Vulkan). So I added a reasoning_budget_tokens >= 0 check to the sampler creation condition. When the budget is unlimited, the sampler is not created, backend sampling stays enabled, and no per-token overhead is added. When a budget is explicitly set (0, 128, 1024, etc.), the sampler is created and works as before. * common: preserve rbudget when grammar is lazy Following up on the review feedback on #21870: keep the reasoning budget sampler when grammar_lazy is true, so the thinking-block grammar suppression from #20970 still works when tools are in use. This way, we only skip the sampler when both no budget is set AND grammar is not lazy. b8786	2026-04-14 12:43:06 +02:00
