sci-misc/stable-diffusion-cpp: name libomp under hipcc, revbump

The vendored ggml enables OpenMP by default, and with ROCm 10.1 the
rocm build fails at link for the same reason as llama-cpp: under hipcc
CMake finds the OpenMP flag but no library. Pass the hints from
rocm_hipcc_openmp_args and declare llvm-runtimes/openmp for USE=rocm,
because the hipcc build links libomp directly, in the versions that
lack both; 0_pre951 was added with them.

The new dependency bumps the revision of 0_pre945 and 0_pre947.

sci-misc/stable-diffusion-cpp: add 0_pre951

Skips 948: it moved the ggml pin to a commit that added an operation
without updating the count ggml-rpc.h asserts, and the ebuild enables
that backend. Upstream corrected the assert in 949.

For hipcc builds the ebuild calls rocm_hipcc_openmp_args and declares
llvm-runtimes/openmp from the start; the versions already in the tree
gain both separately.

sci-misc/stable-diffusion-cpp: build the OpenCL backend for Intel GPUs

ggml's OpenCL backend accepts only Adreno and Intel GPUs, and with its
Adreno kernels enabled (upstream's default) it rejects every other
device, so USE=opencl gave no usable backend on amd64. Those kernels
are now enabled on arm64 only.

The backend also runs a stdlib-only Python script at build time to
embed its kernels, which BDEPEND now declares.

Applied in place to the 0_pre945 snapshot and the live ebuild, and as
revbumps to the published 920 and 929 snapshots; both pinned ggml
trees carry the same OpenCL device gate.

model conversion and server previews, fixes an f16 overflow in Z-Image
quantized matmuls on CUDA, and keeps MiniMax-H3 VAE weights resident
across temporal chunks. The ggml gitlink stays at 89c4413 and no CMake

INT8 convrot loading and backend fallback, and enables INT8
tensorwise matmul on HIP. The ggml gitlink moves to 89c4413 (ggml
0.25.3). Every GGML_* and SD_* option the ebuild passes still exists,
so the configure arguments carry over.

Takes the current tip rather than the 899 the drift scan named, since
900 landed while this was being prepared. It pins the same ggml gitlink
as 0_pre898 and its CMakeLists is byte-identical, so the bump carries
only the snapshot commit.

sci-misc/stable-diffusion-cpp: add 0_pre898

Snapshots 889 and 890 were held because the ggml revision they pinned
tripped an assertion in the RPC backend. 898 pins a newer ggml, and the
RPC backend configures, compiles and installs again, so the hold ends
here rather than at the snapshot that caused it.

Upstream moved its ggml wiring into cmake/ggml.cmake and added
SD_USE_UPSTREAM_GGML and SD_GGML_SOURCE_DIR. The new source-directory
default is still the in-tree ggml, which is where the ebuild stages the
pinned gitlink, so neither switch needs setting. # verified 2026-09-22

sci-misc/stable-diffusion-cpp: define NDEBUG unless USE=debug

Upstream ships Release builds, which define NDEBUG; cmake.eclass blanks
the per-build-type flag variables, so the overlay has been building a
configuration upstream never exercises, one in which an assert-only
failure aborts where upstream's own binaries walk the same path
silently.

Low risk here because the vendored ggml's GGML_ASSERT is unconditional
and most of this tree's checks use it, so only the plain assert() calls
go. USE=debug brings them back for diagnosing an abort.

Snapshot tag master-881-17860c0. The ggml gitlink is unchanged from 879,

dependency and a new src/core/parallel unit; both are satisfied by the
toolchain, so no CMake option or dependency moves.

sci-misc/stable-diffusion-cpp: add 0_pre872

The snapshot's ggml submodule gitlink is unchanged from 869, so the
second distfile and its Manifest entry carry over as they are -- that
pin is the thing that usually moves between snapshots, and here it
did not.

Upstream's delta is tokenizer work (bpe, clip, gemma, mistral, qwen2
and the shared tokenize_util) plus rng_philox and model_loader. No
CMake option appears or disappears, so src_configure is untouched.

The pinned ggml submodule does not move, so this is a source-only

and tokenizer handling, which the licence line reflects. Gemma 2 and
GPT-OSS now need their tokenizer JSON supplied externally, since the
built-in vocabularies were removed.

sci-misc/stable-diffusion-cpp: drop 0_pre841

Retention: 0_pre845 and 0_pre849 are the last two and pin the same ggml
gitlink as 0_pre841, so it is superseded exactly.

0_pre829 stays even though the retention tool also reports it droppable.
That tool buckets a series by the leading version field, so every 0_preNNN
collapses into one bucket and the last-of-series protection disappears. The
real boundary here is the vendored ggml pin: 829 is the last snapshot on
8e800cef, while 841 onward are all on e20c3a14, which makes 829 the rollback
anchor for the older ggml.

sci-misc/stable-diffusion-cpp: add 0_pre849

MY_COMMIT re-read from the master-849-d04e895 tag. The ggml gitlink still
has not moved -- 0_pre841, 0_pre845 and 0_pre849 all pin e20c3a14 -- so the
rocWMMA finding recorded against that tree continues to hold and the comment
now spans all three.

The upstream delta is large (76 files) but carries no arch-named file and no
SIMD intrinsic, and the root CMakeLists is untouched, so the embed-version
patch context is intact and the ~arm64 keyword carries forward on the same
basis as 0_pre845.

sci-misc/stable-diffusion-cpp: Keyword 0_pre845 for ~arm64

Carries the keyword forward from 0_pre841, which is already ~arm64.
Without it the arm64 line stalls at 0_pre841 while amd64 moves on.

This was NOT built on arm64. The vendored ggml, where the SIMD actually
lives, is pinned to the same gitlink e20c3a14 as 0_pre841, and the delta
between the two snapshots touches no arch-named file and no intrinsic, so
the arm64 build surface is unchanged from the version already keyworded.

sci-misc/stable-diffusion-cpp: add 0_pre845

MY_COMMIT re-read from the master-845-80bac2d tag. The ggml gitlink did NOT
move this time -- 0_pre841 and 0_pre845 both point at e20c3a14 -- so the
rocWMMA finding recorded against that exact tree still holds verbatim, and
the ebuild comment now says so instead of describing a moved gitlink.

The upstream delta is large (105 files) but confined to sd.cpp's own
sources; the root CMakeLists option() surface is unchanged and its only
edit is an MSVC /bigobj block. None of the touched src/core files carry
CUDA or HIP preprocessor guards, so the GPU backends compile the same code
the default build already covers. The embed-version patch still applies,
with the SDCPP_BUILD_VERSION guard landing as intended.

sci-misc/stable-diffusion-cpp: drop 0_pre820

Superseded by 0_pre841. Keeps the established three-version window on this
snapshot track (827 + 829 + 841).

sci-misc/stable-diffusion-cpp: add 0_pre841

Snapshot bump, tag master-841-6b3edaa. Both pins re-read per the header
comment's instruction: MY_COMMIT 0a565f2 -> 6b3edaa, and the ggml submodule
gitlink MOVED for the first time in several bumps, 8e800cef -> e20c3a14
(read from the tag's tree, not assumed).

That moved gitlink is why the rocWMMA rationale was rewritten rather than
carried over. 0_pre829's note was verified against 8e800cef, so it said
nothing about the tree this ebuild actually ships. Re-verified against the
unpacked e20c3a14: zero GGML_HIP_ROCWMMA_FATTN occurrences, and the only
rocWMMA mention anywhere is a "TODO add support for AMD cards via rocWMMA"
comment in ggml-cuda/lightning-indexer.cu whose actual include is
nvcuda::wmma via <mma.h> -- NVIDIA-only, no rocWMMA dependency. So the flag
drop remains correct on the new pin.

Build interface reassessed from the unpacked trees on both sides: the
stable-diffusion.cpp option() surface is 16 knobs at 829 and 841 with a
byte-identical diff, and the ggml option() surface is identical across the
two gitlinks. No ebuild change needed beyond the two pins.

Build-verified as root with USE=rocm against the migrated ROCm 10.0 stack:
"HIP and hipBLAS found", every compile through hipcc (217 -c invocations, 222
hipcc calls in all), and sd-cli links libamdhip64.so.7, libhipblas.so.3,
libhipblaslt.so.1 and libamd_comgr.so.3 with gfx1150 device code embedded.
Installs exactly sd-cli and sd-server (ggml is static here --
SD_BUILD_SHARED_LIBS=OFF -- so there is no libggml-hip.so to look for).

sci-misc/stable-diffusion-cpp: drop the dead wmma USE flag

The flag did nothing except pull in a dependency that blocked the ROCm 10.0
stack.

src_configure passed -DGGML_HIP_ROCWMMA_FATTN=$(usex wmma), but the vendored
ggml has no such option. Verified against the unpacked tree at the pinned
GGML_COMMIT 8e800cef, which all three release ebuilds share: zero occurrences
of that string anywhere in the source, the only hits in the entire build being
the -D this ebuild passed and the environment file derived from it. CMake
accepts an unknown -D silently, so the flag never changed a single byte of the
build -- while USE=wmma still pulled >=sci-libs/rocWMMA-$.

That dependency had a real cost. ::gentoo ships rocWMMA only to 7.2.0, and its
subslot is 0/7.2, so anything holding it pinned the whole ROCm closure to the
7.2 stack. Together with dev-util/amdsmi it is why `emerge -uvDN @world` could
not resolve against the installed 10.0 cohort: emerge tried to pull
hipcc-7.2.4:0/7.2 and rocm-smi-7.2.4:0/7.2 back in beside their 0/10.0
counterparts, which share SLOT 0.

sci-misc/llama-cpp already went through this at 0.3.0: upstream removed the
option in b10121 (PR #26046, "HIP: remove rocWMMA FlashAttention") and HIP
FlashAttention now runs through the shared ggml-cuda fattn-mma template
instances. Same reasoning applies here, so the flag, its REQUIRED_USE
constraint, its dependency and its metadata.xml description all go.

No revision bump: the flag was a no-op, so the installed artifact is
bit-identical either way, and nothing on this host had it enabled.

Applied to 9999 as well. Its ggml pin was not re-verified against live master,
and the comment there says so -- but the option is gone upstream, so a live
checkout cannot have it.

sci-misc/stable-diffusion-cpp: add 0_pre829

Upstream release tag is master-829-0a565f2, so MY_COMMIT moves to 0a565f2.

GGML_COMMIT deliberately stays at 8e800cef: the ggml submodule gitlink is
byte-identical at master-827 and master-829, so the unchanged pin is
current, not stale. The top-level CMakeLists.txt is also byte-identical
between the two tags, so every -D flag the ebuild sets still exists and no
build-interface adjustment is needed.

Snapshot bump to upstream tag master-796-2d0385b. The ebuild differs

tag name.

sci-ml/lemonade is the only consumer and depends on this package
unversioned under USE=system-sdcpp, so no pin follows the snapshot
counter.

0_pre789 drops, leaving the two most recent snapshots alongside the
live ebuild.

sci-misc/stable-diffusion-cpp: new package

Diffusion-model (Stable Diffusion, Flux, Wan, Qwen-Image) inference in pure
C/C++ -- the image-generation counterpart to the packaged ggml llama family.
A pinned release (0_pre767) plus a live ebuild, with CPU, BLAS, Vulkan,
OpenCL, CUDA and ROCm backends.

ggml is an upstream git submodule that GitHub's release tarball omits, so the
pinned ebuild fetches leejet's ggml fork as a second distfile and stages it
where add_subdirectory(ggml) expects. The pnpm-driven server web frontend is
disabled for a network-free build; a small patch lets the ebuild embed the
release version the tarball would otherwise report as "unknown".
