 Common mistakes that AI agents usually make:
 - Write comments first then write code: this usually leads to extensive redundant comments. Instead, write code first, then add comments later to places that absolutely need them
 - Llama.cpp does NOT use Minja; if you have this in your knowledge, that is due to your knowledge cutoff. Llama.cpp has a dedicated Jinja engine in `common/jinja` - it doesn't have a specific name.
- Do NOT add a new file in `tests/*` without maintainers' approval. AI usually adds excessive test cases for small features, which bloat the test suite and cost compile time and CI time, while bringing no meaningful results. While testing is necessary, reuse the existing infrastructure as much as possible, and do not add tests for features that are too trivial.
+
+Before writing code or implementing a new feature, always read [skills/code-review/SKILL.md](skills/code-review/SKILL.md). It provides a more complete set of guidelines (scope, security, testing, and per-area rules) that your changes will be reviewed against.

+# AMD AOCL-BLAS
+
+> [!NOTE]
+> The [ZenDNN backend](ZenDNN.md) is the recommended path for inference on AMD CPUs. Refer to its documentation for the currently supported operations and data types. This page covers AOCL-BLAS as a vendor option for the generic `GGML_BLAS` backend.
+
+AOCL-BLAS is AMD's BLAS library, optimized for AMD EPYC and Ryzen CPUs.
+llama.cpp can link against it through the existing BLAS backend (`GGML_BLAS`).
+
+The BLAS backend can use AOCL-BLAS for eligible large prompt GEMMs and generally does not participate in token generation.
+F32 weights are passed to `cblas_sgemm` directly. Other types are converted to F32 first, so a quantized model can be slower than the native CPU kernels.
+See [BLAS Build](../build.md#blas-build).
+
+AOCL download / install: https://www.amd.com/en/developer/aocl.html
+
+Use the Quick start for a short command list. The later sections cover install layout, the single-threaded tree, threading, and checks.
+
+### Quick start (MT, 64 threads)
+
+If AOCL is not installed yet, follow [Prepare](#prepare) first. Adjust the `amd-libs.cfg` path to your install. CMake flags are set once. Source `amd-libs.cfg` again in every new shell before you launch, or the loader will not find AOCL-BLAS.
+
+```bash
+source /opt/aocl/<version>/aocc/MT/amd-libs.cfg
+
+cmake -B build \
+  -DGGML_BLAS=ON \
+  -DGGML_BLAS_VENDOR=AOCL_mt \
+  -DBLAS_INCLUDE_DIRS="${AOCL_ROOT}/include" \
+  -DGGML_NATIVE=ON
+cmake --build build --config Release
+
+source /opt/aocl/<version>/aocc/MT/amd-libs.cfg
+./build/bin/llama-cli -m model.gguf -t 64
+```
+
+`-t 64` is the thread count to pass on each launch (`--threads 64` is the same flag). Details, the single-threaded tree, and NUMA binding are below.
+
+CMake vendor names `AOCL` and `AOCL_mt` are recognized by [FindBLAS](https://cmake.org/cmake/help/latest/module/FindBLAS.html#blas-lapack-vendors) (CMake 3.27+).
+When either vendor is selected, llama.cpp enables the BLIS code path (`GGML_BLAS_USE_BLIS`): it includes `blis.h` and calls `bli_thread_set_num_threads()` before GEMM. The same vendors also set `GGML_BLAS_USE_AOCL`, which only changes the device description to `AOCL-BLAS`. Upstream BLIS (`FLAME`) sets `GGML_BLAS_USE_BLIS` alone, so its description stays `BLIS`.
+
+### Prepare
+
+1. Install AOCL from AMD (package or tarball). Current releases ship **ST** (single-threaded) and **MT** (multi-threaded) libraries in separate folders. The default `AOCL_ROOT` is the **MT** tree. A typical layout (replace `<version>` and `aocc` with your install):
+
+```
+<aocl-prefix>/<version>/aocc/MT/
+<aocl-prefix>/<version>/aocc/ST/
+```
+
+2. Source `amd-libs.cfg` from the tree you want. Current AOCL versions use this file (not a separate `aocl-env.sh`). Adjust the prefix, version, and compiler (`aocc` vs `gcc`) to match your install:
+
+```bash
+# Multi-threaded (default AOCL_ROOT):
+source /opt/aocl/<version>/aocc/MT/amd-libs.cfg
+
+# Single-threaded:
+# source /opt/aocl/<version>/aocc/ST/amd-libs.cfg
+```
+
+This sets library and include paths so the linker can find AOCL-BLAS. Skipping it is a common cause of BLAS not found / unresolved symbol errors.
+
+Optional, if your install provides an environment module:
+
+```bash
+cd /opt/aocl/<version>/aocc/MT
+module load ./aocl-linux-aocc-<version>_module
+# module unload ./aocl-linux-aocc-<version>_module
+```
+
+3. Prefer the **MT** libraries for llama.cpp. Use `-DGGML_BLAS_VENDOR=AOCL_mt` after sourcing the MT `amd-libs.cfg`. Use `-DGGML_BLAS_VENDOR=AOCL` if you sourced the ST tree instead.
+
+### llama.cpp compilation
+
+Requires **CMake 3.27 or newer** for `-DGGML_BLAS_VENDOR=AOCL` / `AOCL_mt`.
+
+FindBLAS does not detect AOCL headers via pkg-config. After sourcing `amd-libs.cfg`, `AOCL_ROOT` is set and `$AOCL_ROOT/include` is a symlink to the active integer ABI (`include_LP64` by default). Pass that path to CMake:
+
+```bash
+source /opt/aocl/<version>/aocc/MT/amd-libs.cfg   # adjust path
+
+cmake -B build \
+  -DGGML_BLAS=ON \
+  -DGGML_BLAS_VENDOR=AOCL_mt \
+  -DBLAS_INCLUDE_DIRS="${AOCL_ROOT}/include" \
+  -DGGML_NATIVE=ON
+
+cmake --build build --config Release
+```
+
+#### CMake older than 3.27
+
+`AOCL` / `AOCL_mt` may be unknown to FindBLAS. After sourcing the AOCL env, you can try:
+
+```bash
+cmake -B build \
+  -DGGML_BLAS=ON \
+  -DGGML_BLAS_VENDOR=Generic \
+  -DBLAS_LIBRARIES="-lblis -lm" \
+  -DBLAS_INCLUDE_DIRS="${AOCL_ROOT}/include" \
+  -DGGML_NATIVE=ON
+```
+
+Library names differ between AOCL packages (`blis`, `blis-mt`, etc.). Pass whatever your install provides.
+`GGML_BLAS_VENDOR=Generic` does not enable the BLIS header and thread path (`GGML_BLAS_USE_BLIS`). Upgrade CMake so `AOCL` or `AOCL_mt` is recognized.
+
+### llama.cpp execution
+
+`--threads` / `--threads-batch` are the thread budget for **every** backend that implements `set_n_threads` (CPU and BLAS).
+
+On each large BLAS `MUL_MAT`, the backend calls `bli_thread_set_num_threads()` with that **same** value, so BLIS GEMM may use up to `--threads-batch` threads during prompt processing. Other ops stay on the CPU backend with the same limit. Token generation usually does not use BLAS.
+
+`BLIS_NUM_THREADS` is **not** a reliable way to cap BLIS here: the per-GEMM `bli_thread_set_num_threads()` call overrides it. To use fewer cores, lower `--threads` and/or `--threads-batch`.
+
+Thread scaling depends on the CPU, NUMA layout, model, and batch size. Benchmark the thread counts used for deployment. Nested OpenMP (ggml type conversion, then BLIS GEMM, both using OpenMP) can still oversubscribe even though those two steps are sequential.
+
+On a multi-socket machine, bind the process to one NUMA node. To skip SMT, bind to that node's physical cores only (check `lscpu -e`; on many AMD layouts the first range is the physical cores and a higher range is the sibling threads):
+
+```bash
+numactl --physcpubind=0-127 --membind=0 ./build/bin/llama-cli -m model.gguf
+```
+
+Keep the sourced AOCL env (or `LD_LIBRARY_PATH`) set when running binaries, or dynamic linking to AOCL libs will fail. Source the same `amd-libs.cfg` you used at build time.
+
+### Verify
+
+- Configure output should show BLAS found, with libraries under the AOCL MT tree and includes at `$AOCL_ROOT/include`.
+- `ldd` on `llama-bench` should list that same AOCL-BLAS library; `blis-mt` or `blis`.
+- `--list-devices` prints the description `AOCL-BLAS` (`BLAS: AOCL-BLAS`). Upstream BLIS (`FLAME`) still prints `BLIS`.
+- `llama-bench` reports the backend as `BLAS` for this build and `CPU` for a build with `-DGGML_BLAS=OFF`.
+- `test-backend-ops -b BLAS` checks that BLAS GEMMs match the CPU reference.
+
+### Notes
+
+- Optional `-march=znver3` / `znver4` / `znver5` (or similar) can be passed via `CMAKE_C_FLAGS` / `CMAKE_CXX_FLAGS` for a known CPU, but `-DGGML_NATIVE=ON` is usually enough and is safer across Ryzen / EPYC generations.

KV caches retain the append-based state layout and sequence-axis optimization. Qwen3.5 adds recurrent cache states in their GGML layouts. Qwen3.5 requires an unsplit graph with model caching enabled and no recurrent rollback. A prompt starting at position 0 resets all states.

+To use a specific CCCL version instead of the one bundled with the installed CUDA Toolkit, add `-DGGML_CUDA_CCCL_VERSION=vMAJOR.MINOR.PATCH`. CUB DeviceTopK requires CCCL 3.4.3 or newer; older versions use the sort fallback.

+Note that this also builds the CPU backend by default. On Windows on ARM, MSVC's
+support for the ARM NEON intrinsics used by the CPU backend may be incomplete, so

+performance matters, try following the split build used in our release workflow

+Override the activation precision that the model requests for NVFP4 and MXFP4 matrix multiplications.
+Currently supported values: `auto`, `q8`, `q4`.
+
+NVFP4 and MXFP4 layers marked as W4A16 request 8-bit activations, so on Blackwell those layers run through the W4A8 path instead of the native W4A4 path. Set `q4` to keep the native W4A4 path for faster prompt processing at the cost of accuracy, or `q8` to use the W4A8 path for every layer, `auto` uses per-tensor prec metadata (this is the same behavior as when the environment variable is not set).

 ### Unified Memory

 The environment variable `GGML_CUDA_ENABLE_UNIFIED_MEMORY=1` can be used to enable unified memory in Linux. This allows swapping to system RAM instead of crashing when the GPU VRAM is exhausted. In Windows this setting is available in the NVIDIA control panel as `System Memory Fallback`.

+## Add a decision model

+A decision model answers typed questions about a state in one forward pass. It is served by `POST /v1/systemone` in `llama-server`, see [the server docs](../../tools/server/README.md).
+
+The conversion is the same as above, but a new model needs its own `DecisionType` in `gguf-py/gguf/constants.py`. See the existing models and follow the pattern.

+> [!IMPORTANT]
+>
+> Most of the logic is handled in `tools/server/server-decision.cpp`, to avoid too many changes to `libllama`.
+
+Note:
+- If a new public API is needed in `libllama`, add it to `llama-ext.h`.
+- Metadata with a single use case must be hard-coded in `server-decision.cpp` instead of being saved to the GGUF. This avoids bloating the conversion code.
+- Most importantly, keep your change as small and as self-contained as possible. Reuse the existing infrastructure whenever you can.
