Summary

Brings the OpenWhispr whisper.cpp fork up to upstream v1.9.1 and extends the bundled CUDA builds to RTX 50-series (Blackwell, sm_120) GPUs. The CUDA jobs in build-binaries.yml previously targeted 75;80;86;89 on CUDA 12.4, which can't compile for Blackwell — nvcc 12.4 rejects compute_120; this adds sm_120 and bumps the toolkit to 12.9.1 (Blackwell support landed in CUDA 12.8), keeping RTX 20-40 coverage. The produced CUDA binary was verified to embed sm_120 SASS with cuobjdump --list-elf.

Changes

  • Merge upstream whisper.cpp through v1.9.1.
  • .github/workflows/build-binaries.yml: add sm_120 to CUDA_ARCHITECTURES (now 75;80;86;89;120); bump CUDA toolkit 12.4.0 → 12.9.1 — Windows redist component versions and Linux package/paths (cuda-toolkit-12-9, /usr/local/cuda-12.9).

This reverts commit be867ea.

Sorry about this noise, I thought it was worth a try.
This commit adds explicit casts to float for -INFINITY.

The motivation for this is that in CUDA 11.8.0, the -INFINITY macro is
defined as a double (a header provided NVCC). This triggers a warning
and hence causes a CI failure in whisper.cpp. I belive that this header
might have been updated in CUDA 12 which is why we don't see this
warning.

…/1477)

For a given output position j on the time axis, only input positions
i such that i*s0 <= j < i*s0 + K contribute -- i.e.
i in [ceil((j - K + 1)/s0), floor(j/s0)] intersected with [0, IL-1].
That's at most ceil(K/s0) values (typically 2 for stride==K/2
transposed convs).

The current kernel iterates the full IL range and filters with an
`if`, amplifying per-thread work by IL/ceil(K/s0) (~160x for IL=320,
K=10, s0=5 -- a representative codec-decoder shape). On Apple M1
the wasted work trips the macOS GPU watchdog
(kIOGPUCommandBufferCallbackErrorImpactingInteractivity) on long
graphs.

Compute i_min, i_max analytically before the inner loop and iterate
only [i_min, i_max]. Output is bit-identical (same multiplies and
adds in the same order); loop bound shrinks by IL/ceil(K/s0).

Tested on M1 with a downstream consumer running a TTS codec at full
T_codec; end-to-end codec decode ~3-4x faster, zero watchdog hits
across long synthesis runs vs ~30% pre-patch.
Add missing `#include <mutex>` in ggml-backend-device.cpp.

* add im2col_3d

Before, we relied on a transient import from `cub/cub.cuh`, which is
bad practice to do as cub may not always expose cuda/iterator
* cuda: tighten snake fusion type checks for all operands (defensive, sync vulkan)

* cuda: reject snake fusion when ne[2] or ne[3] > 1 (mirror vulkan PR review)

* cuda: merge type_ok and types_ok into a single types_ok (address am17an review)

* cuda: filter ADD/SUB/MUL/DIV in supports_op to F32/F16

bin_bcast only dispatches F32/F16 type triplets, mirror the
vulkan filter so unsupported types fall back through cpy
instead of aborting.

* test-backend-ops: extend snake_fuse to rank-4 with ne[2]/ne[3] > 1 cases
`im2col_cuda` and `im2col_3d_cuda` both dispatch with
`block_nums.y = OW`. CUDA caps grid Y at 65535. Conv1d encoders on
raw 16 kHz audio with T > 65535 (~ 4 s) trip the limit -- e.g. SEANet
at 11 s lands at OW = 176000 -- and the launch returns
`invalid configuration argument`.

Clamp `block_nums.y` to `MIN(OW, MAX_GRIDDIM_Y)` and loop inside the
kernel with stride `MAX_GRIDDIM_Y`. Same in-kernel stride pattern
already used for the z axis (`MAX_GRIDDIM_Z`). Both 2D `im2col_kernel`
and 3D `im2col_3d_kernel` need the same fix. Bit-identical for
OW <= 65535 (single iteration of the new outer loop).

Tested on T4 / Jetson Orin with a SEANet encoder running on 11 s /
16 kHz audio (im2col reaching OW ~ 176000); pre-fix launch returns
`invalid configuration argument`, post-fix runs to completion.
Existing test-backend-ops im2col cases unchanged.

* cpu: add GGML_OP_COL2IM_1D

Add the overlap-add (scatter-add) step of a 1D transposed convolution.
A ConvTranspose1d factorizes as a GEMM followed by col2im: a weight
pre-permuted to [IC, K*OC] is contracted against the [IC, T_in] input
with mul_mat to produce a column matrix [K*OC, T_in], and col2im_1d
scatters those columns back into the [T_out, OC] signal, with
T_out = (T_in - 1)*s0 + K - 2*p0.

Keeping the contraction as a plain mul_mat leaves the heavy work on the
optimized (and quantizable) matmul kernels, so col2im_1d only does the
cheap overlap-add.

CPU uses a gather formulation parallelized over output channels,
supporting F32, F16 and BF16 with an F32 accumulator.

* tests: add backend coverage for GGML_OP_COL2IM_1D

Add test_col2im_1d next to the conv_transpose_1d cases, covering F32,
F16 and BF16 across eight geometries: the canonical kernel = 2*stride
DAC upsampling shape, overlap, no overlap, cropping (p0 = 1 and
p0 = stride/2), kernel < stride with zeroed gaps, kernel not a
multiple of stride, and a single column unfold.

Perf mode gets three real vocoder stage shapes reporting memory
bandwidth. max_nmse_err relaxes to 5e-4 for F16 and BF16.

* cpu: harden GGML_OP_COL2IM_1D

ggml_col2im_1d validates s0, oc, p0 and input contiguity at graph
build time, before the oc division, protecting every backend at once.
The kernel asserts the contiguity its flat indexing assumes and its
doc states the full output length including the crop term.

The kernel parallelizes over the time axis: the split stays balanced
down to OC = 1, where the previous channel split was single threaded.
Values are bit identical on the three real vocoder chains, two out of
three improve.

* tests: extend the GGML_OP_COL2IM_1D grid

The eval grid grows to eleven geometries: OC = 1 (mono output stage),
K = 1 with stride > 1 (sparse scatter, every gap position zeroed) and
a crop down to T_out = 2 where all the gather bounds act at once.

* tests: add col2im_1d equivalence test

tests/test-col2im-1d.cpp proves mul_mat + col2im_1d matches the
native ggml_conv_transpose_1d on the CPU backend, F32 bit exact, F16
and BF16 through casts of the column matrix. test-backend-ops cannot
cover this for a CPU only op since the CPU backend is its own
reference there.

* rpc: bump protocol patch version for GGML_OP_COL2IM_1D

GGML_OP_COUNT goes from 96 to 97 with the new op, which trips the
static_assert in ggml-rpc.h. Bump RPC_PROTO_PATCH_VERSION since the
op is appended and no existing op code shifts.
…and Flash Attention (llama/24123)

* vulkan: add support for valve fp16 dot2 extension

* use macro for dot2 path choice

* properly check for the feature

* add dot_product abstraction to reduce preprocessor branching
* Add missing syncthreads before resuing cub_temp_storage

__syncthreads() is required before being allowed to resue TempStorage

https://nvidia.github.io/cccl/unstable/cub/api/classcub_1_1BlockLoad.html#_CPPv4I0EN3cub9BlockLoad4LoadEv20RandomAccessIteratorRA14ItemsPerThread_1Ti

* Add one more missing __syncthreads

Could also double-buffer, but alternative is to simply ensure all
threads have read smem* before writing to it again in the next loop
iteration

* Remove unused smem from ssm_scan_f32
* Make ggml_gated_delta_net take only the initial recurrent state (D, 1, n_seqs) and passes the snapshot count K as an op parameter instead of inferring it from state->ne[1].

Remove the padding hack and copy all emitted snapshots into the recurrent cache with a single strided ggml_cpy

* Make GDN changes in all backends. Address review comments.

* Fix CI build errors
* vulkan: use medium matmul tile on Asahi Linux

* vulkan: switch Apple detection to Honeykrisp driver id

* cuda: support concat for scalar types

* Update concat.cu

* fix metal ci issue
Adds a `--version` option to whisper-cli that prints the library version
via `whisper_version()` and exits, plus a corresponding entry in the help
output. Mirrors the existing `-h`/`--help` handling.

Closes ggml-org#608
* ci : only trigger release jobs for tags

This commit removes the building of the release jobs on pushed to
master.

The motivation for this is that it can be confusing at the momement when
releasing that the push to master also triggers the release jobs but
the actual release will be skipped. With this change the release job is
only run when a tag is pushed which should result in a single Release
github actions job and make it easier to follow.

* ci : add GGML_NATIVE=OFF and build all cpu-variants

This commit adds -DGGML_BACKEND_DL=ON, -DGGML_NATIVE=OFF, and
-DGGML_CPU_ALL_VARIANTS=ON to the releases.

The motivation for this is that currently the Windows BLAS build
uses the native CPU instructions and if target systems do not support
these instructions, the build will fail like the linked issue reports.

Resolves: ggml-org#3889

* ci : update ubuntu-cpu release job for all variants [no ci]

This commit enables the ubuntu-cpu job to include all cpu variants and
ensures that the ggml backend libraries are built into the bin directory
similar to how llama.cpp does it.

The following is a build on my fork with this change:
