When a tile's upper 16 slots are all padding (router index 0xFFFFFFFF), skip the second dotx16_reduce8 half. Numerically identical (skipped lanes are padding). Applied to all eight *_f32_ns MoE GEMMs; default on, opt out with GGML_OPENCL_MOE_RAGGED_FP16=0. * opencl: quarter-granularity ragged MoE tile-skip (8-col skip-groups) Replace the two half-tile dotx16_reduce8 calls in the 8 *_f32_ns MoE GEMMs with four dotx8_reduce4 (8-column) calls, skipping each empty trailing skip-group independently. Padding is always trailing, so the kernel rounds the valid count up to the skip granularity and skips fully-padding groups. Byte-identical to the non-skipped path.

(#25464) * opencl: fix garbled output for Q6_K weights with ne01 % 128 != 0 on Adreno Observed with granite-3.1-3b-a800m-instruct, whose vocab is an odd number. Route Q6_K dense mul_mat with ne01 % 128 != 0 off the noshuffle path: decode (ne1==1) uses the correct flat GEMV and the matching GEMM (ne1>1) falls back to CPU (the flat convert has no verified small-batch GEMM kernel for these shapes). All standard hidden/FFN/vocab dims are multiples of 128 and keep the noshuffle path. * opencl: reserve alignment slack for the SOA subbuffer carve in alloc size set_tensor carves quantized weights into per-component subbuffers (d/q, ql/qh/s/d, ...) whose origins are each rounded up to the device base address alignment. When a component's size is not a multiple of the alignment, the carve extends past ggml_nbytes(tensor) and the last subbuffer overlaps the next tensor in the pool -- e.g. q6_K [1536, 49155]: size_s = 49155*96 ends 32 bytes past a 128-byte boundary, so the d subbuffer ends 96 bytes past the tensor's allocation, and whichever of the two neighboring tensors is uploaded last silently corrupts the other (here: the last vocab rows' block scales). This affects any quant type whose component sizes can be misaligned, on any shape with ne01 not a multiple of the alignment granularity; standard power-of-two dims are unaffected. Implement get_alloc_size for the OpenCL buffer type and reserve the worst-case carve slack (4 aligned gaps; 5 components max, q5_K) for quantized tensors. Costs at most 512 bytes per quantized tensor at the observed 128-byte alignment. * opencl: use lm based q6_k mm when ne1 is not multiple of 128 --------- Co-authored-by: Li He --- ggml/src/ggml-opencl/ggml-opencl.cpp | 41 ++++++++++++++++++++++++++-- 1 file changed, 39 insertions(+), 2 deletions(-) diff --git a/ggml/src/ggml-opencl/ggml-opencl.cpp b/ggml/src/ggml-opencl/ggml-opencl.cpp index 10e183530..38600f31a 100644 --- a/ggml/src/ggml-opencl/ggml-opencl.cpp +++ b/ggml/src/ggml-opencl/ggml-opencl.cpp @@ -6242,8 +6242,14 @@ inline bool use_adreno_kernels(const ggml_backend_opencl_context *backend_ctx, c threshold_ne0 = 128; threshold_ne1 = 128; } - return tensor->ne[0] >= threshold_ne0 && tensor->ne[1] >= threshold_ne1 && + bool threashold_ok = tensor->ne[0] >= threshold_ne0 && tensor->ne[1] >= threshold_ne1 && tensor->ne[2] == 1 && tensor->ne[3] == 1; + + // q6_K adreno kernels requires ne1 is multiple of 128 + if (tensor->type == GGML_TYPE_Q6_K) { + return threashold_ok && tensor->ne[1] % 128 == 0; + } + return threashold_ok; } inline bool use_adreno_moe_kernels(const ggml_backend_opencl_context *backend_ctx, const ggml_tensor *tensor) { @@ -6273,6 +6279,19 @@ static inline bool use_flat_gemv_for_large_m_q6_K(const ggml_tensor *tensor) { // threshold is well above typical hidden/FFN dims, but below typical vocab sizes. // q6_K flat gemv is worse for smaller K; 2048 seems to be a reasonable threshold. // note that this forces large M weights to use LM GEMM. + // The noshuffle (transposed-weight) layout packs 2 rows per 32-bit texel and the + // gemv reads it with a ne01/2 texel stride and an exact-cover dispatch of + // ceil(ne01/2 / 64)*64 work-items with no store guard; the gemm uses 4-row tiles. + // It is therefore only correct for ne01 % 128 == 0: an odd ne01 (e.g. granitemoe + // lm_head [1536, 49155] -- odd vocab) truncates the texel stride, misaligning every + // odd column of the transposed layout (gross garbage) and dropping the last row; + // other non-multiples over-dispatch and write past the end of dst.
