+
+## Background
+
+**ET** is a llama.cpp backend targeting the fully open source manycore
+RISC-V accelerator platform [ET-SOC](https://github.com/aifoundry-org/et-man).
+
+
+## Limitations
+
+The ET backend runs several of the major OSS models with some limitations:
+
+- Only limited set of operations is supported (check [../ops.md](../ops.md)
+  and [../ops/ET.csv](../ops/ET.csv)).
+- Only `q8_0`, `q4_0` (and partially `fp16`, `q4_K`) quantization is supported.
+- Only one llama.cpp instance can use device at the same time (current firmware
+  limitation).
+- Limited (but working) MoE model support
+
+As a result of the above, only select models can run fully on ET-SOC
+(you can actually run any model llama.cpp supports, but some/most operations
+will likely fallback to CPU backend).
+
+Fully supported models:
+- Qwen3 models (without MoE), e.g.
+  [ggml-org/Qwen3-0.6B-GGUF:q8_0](https://huggingface.co/ggml-org/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q8_0.gguf) or
+  [ggml-org/Qwen3-14B-GGUF:q8_0](https://huggingface.co/ggml-org/Qwen3-14B-GGUF/blob/main/Qwen3-14B-Q8_0.gguf).
+- Llama3.2 (1B/3B), e.g.
+  [lmstudio-community/Llama-3.2-1B-Instruct-GGUF:q8_0](https://huggingface.co/lmstudio-community/Llama-3.2-1B-Instruct-GGUF/blob/main/Llama-3.2-1B-Instruct-Q8_0.gguf).
+- SmolLM2, e.g.
+  [unsloth/SmolLM2-135M-Instruct-GGUF:q8_0](https://huggingface.co/unsloth/SmolLM2-135M-Instruct-GGUF/blob/main/SmolLM2-135M-Instruct-Q8_0.gguf)

+
+## Build
+
+### I. Prerequisites
+
+1. **Install custom RISC-V toolchain** - Follow instructions at:
+   [https://github.com/aifoundry-org/riscv-gnu-toolchain/tree/et/aifoundry](https://github.com/aifoundry-org/riscv-gnu-toolchain/tree/et/aifoundry)
+
+2. **Install ET platform** - Follow instructions at:
+   [https://github.com/aifoundry-org/et-platform](https://github.com/aifoundry-org/et-platform)
+
+Both should be installed to `/opt/et` (or set `ET_TOOLCHAIN` and `ET_PLATFORM`
+environment variables accordingly).
+
+```sh
+# Set toolchain and ET platform path (/opt/et is default)
+export ET_TOOLCHAIN=/opt/et
+export ET_PLATFORM=/opt/et
+```
+
+### II. Build llama.cpp
+
+Check out llama.cpp with ET backend (this should checkout `et` branch):
+
+```sh
+git clone https://github.com/aifoundry-org/llama.cpp
+cd llama.cpp
+```
+
+Build:
+
+```sh
+cmake -B build -DGGML_ET=ON
+cmake --build build --config Release
+# Optionally:
+# cmake --install build
+```
+
+Build targeting sysemu backend instead of physical hardware:
+```sh
+cmake -B build -DGGML_ET=ON -DGGML_ET_SYSEMU=ON
+cmake --build build --config Release
+```
+
+### III. Run
+
+Run llama.cpp binaries as usual. (Of course, please make sure you have the
+ET-SOC device installed and kernel driver loaded).
+
+```sh
+llama-cli -m mymodel.gguf
+# or
+llama-server -hf ggml-org/Qwen3-8B-GGUF:q8_0
+```
+
+If you want to run llama.cpp binaries (e.g. `llama-cli`) inside docker
+container, you should let it access device files:
+
+```sh
+docker run \
+    --device=/dev/et0_mgmt:/dev/et0_mgmt \
+    --device=/dev/et0_ops:/dev/et0_ops \
+    ...
+```
+
+## Develop
+
+Compute kernels are developed within `ggml/src/ggml-et/et-kernels` folder.
+Build is performed using custom RISC-V GNU toolchain and is managed by cmake.
+At the moment kernels are build as baremetal elf files, without
+standard lib or any other dependencies. All the yummy parts are written
+in inline assembler.
+
+Most kernels are very naive with lots of low hanging fruits left:
+
+> [!IMPORTANT]
+> Several assembly instructions emmited by the compiler are not implemented
+> in hardware and software emulation in firmware is not ready yet.
+> Eventually firmware will transparently trap unimplemented instructions
+> and will emulate them inside exception handler. Until then, kernel
+> build process includes step that checks compiled kernels and fails if any unimplemented
+> instructions are found. Problematic ones follow:
+> `FDIV.PI`, `FDIVU.PI`, `FREMU.PI`, `FREM.PI`, `FDIV.S`, `FDIV.PS`, `FSQRT.S`, `FSQRT.PS`, `FRSQ.PS`, `FSIN.PS`
+>  and (long cast) `FCVT.S.L`, `FCVT.S.LU`, `FCVT.L.S`, `FCVT.LU.S`
+> What this means, is that for now you should avoid doing any division involving floats,
+> any trigonometry or casting longs into floats.
+> Some workarounds are implemented in `math_fp.h` (`et_fdiv`, `et_powf` etc) and
+> long casting (presuming longs are small enough to fit into 32bits) can be
+> done via `int` like `a = (float)(int)(b)`.
+
+> [!TIP]
+> There are some slightly higher level helpers (abstracting more
+> complex instructions like tensor extension or synchronization primitives)
+> inside `et_platform`, directory `et-common-libs/include/etsoc/isa/`. It was
+> originally developed for firmware needs and is not included into compute
+> kernel build process. Feel free to take ideas/code from there or try linking
+> it in.
+
+Before commiting any changes to operations and/or kernels, don't forget
+to update supported ops reports (instructions at `docs/ops.md`).
+
+When logging is enabled (e.g. by setting `--log-file` cli param),
+each compute kernel run outputs a line with
+pipe-delimited key-value pairs containing kernel level performance infomation.
+Line is prefixed with `ET_PERF`:

+Keys depend on the operation, but some are always present.
+`flops` in this case counts effective floating point operations and not floating
+point operations per second.
+
+You can enable ET-SOC runtime level ET-SOC profiling by setting environment
+variable `GGML_ET_PROFILE` to a path. Profiling/tracing results will be written
+to `GGML_ET_PROFILE/et_runtime_trace.json` and `GGML_ET_PROFILE/kernel_map` on exit.
+
+### Uberkernel
+
+The in-knernel implementaiton of device dispatch/kernel fusion. The ET SDK has a non-trivial op-to-op gap. `Uberkernel` (name taken from the original Esperanto AI's compiler)
+dispatches multiple already existing kernel implementations with device side synchronization. Due to the processor's design, there is no natural memory visibility
+horizon between sub-kernel invocations. This makes uberkernel much more difficult to develop and debug. Currently Uberkerel is hidden begind the
+`GGML_ET_UBERKERNEL` environment variable and is disabled by default. Setting it to 1 enables it and provides significant performance improvements but is only
+validated for the LLaMA 3.2 model family and Qwen 3.5.
+
+## Roadmap
+
+As of writing the documentation the ET backend is capable of running most models and smaller ones at usable speed given the low power profile of the processor. We'd
+address the following capabilities in the future:
+
+* Enable Uberkernel for all models
+* More oprtator support
+* Better TTS model support
+* Enable more quantization format support

+// 2D F32 convolution on the ET-SoC-1 matrix engine (GGML CONV_2D layout).
+//
+// LAYOUT (matches GGML's standard CONV_2D, cwhn=false; wireable directly):
+//   src1 input :  ne = [W, H, Cin, N=1]      memory: input [n][cin][h][w]
+//   src0 filter:  ne = [Kw, Kh, Cin, Cout]   memory: filter[oc][ic][kh][kw]
+//   dst  output:  ne = [W, H, Cout, N=1]     memory: output[n][oc][h][w]
+//
+// CONSTRAINTS (enforced at supports_op):
+//   F32 throughout, N == 1, Cin % 16 == 0, Cout % 16 == 0, positive
+//   stride/pad, dilation == 1. Tile/L2SCP limits are checked here.
+//
+// MEMORY MODEL:
+//   Each active shire uses its own 2 MB local L2 SCP:
+//     filter slice | pin buffer 0 | pin buffer 1? | output staging? | scratch
+//
+//   The filter slice contains only the output-channel tiles (`mt`) consumed
+//   by this shire's tile assignment. That keeps hart-0's inner-loop
+//   tensor_loads local to the shire and avoids packing unused filter slabs.
+//
+// THREADING (multi-minion, multi-shire):
+//   PHASE 1 (per-shire filter pack): hart-1's pack this shire's filter
+//     slice into local L2 SCP. Work is slab-striped across the 32 minions.
+//
+//   PHASE 2 (per-shire compute): hart-1's pack the input pin chunks while
+//     hart-0's run the matrix engine. Pin double-buffering hides the next
+//     chunk pack behind the current chunk's FMA pipeline when Cin does not
+//     fit in one local buffer.
+//
+// PERFORMANCE STRATEGIES:
+//   1. Local filter slice: pack only the `mt` values this shire consumes;
+//      inner-loop tensor_loads stay shire-local.
+//   2. Pin Cin streaming + chunk double-buffer: pack one
+//      chunk while computing the prior one.
+//   3. TenC save/restore: f0..f31 IS the TenC accumulator;
+//      spill/refill via L2 SCP scratch lets each hart hold multiple
+//      partial accumulators across chunks.
+//   4. OW%16 staging: for partial-tile output, write to a
+//      padded L2 SCP region then have one hart scalar-emit to DRAM.
+//
+// WHY THE FILTER PACK EXISTS:
+//   GGML's OIHW filter has stride Kh*Kw*4 between consecutive Cin elements
+//   (e.g. 36 bytes for 3x3) — usually NOT a multiple of 64, so plain
+//   tensor_load cannot gather it directly. The per-slab pack into a
+//   Cin-innermost form gives every per-tap slab a flat 64-byte row stride
+//   and enables tensor_load.
+//
+//   Picking M=Cout, N=W means TenC's natural row stride matches NCHW
+//   output's per-channel stride (H*W*4) — the output store is a clean
+//   tensor_store with no transpose. The price is that conv_size/conv_ctrl
+//   no longer help with W boundaries (mask gates M, not N), so we handle
+//   boundaries up-front by zero-padding the input in L2SCP.

+// Bare Metal GET_ROWS F32 Kernel
+// Extracts specific rows from a source tensor based on row indices
+//
+// Algorithm:
+// 1. Read row indices from src1 (int32 tensor)
+// 2. For each index, extract the corresponding row from src0
+// 3. Copy the row data to the output tensor dst
+// 4. Handle different input types: F32, Q8_0, Q4_0, and Q4_K (quantized)
+//
+// Operation: dst[i] = src0[indices[i]] for i = 0..num_indices
+//
+// Features supported:
+// - F32 input data (direct copy)
+// - Q4_0 quantized input data (dequantized to F32)
+// - Q8_0 quantized input data (dequantized to F32)
+// - Q4_K quantized input data (dequantized to F32)
+// - Int32 row indices

+// Bare Metal MUL_MAT_ID Kernel (Mixture of Experts)
+//
+// ALGORITHM:
+// MUL_MAT_ID performs batched matrix multiplication with expert routing.
+// Each output element selects which expert matrix to use based on an index tensor.
+//
+// INPUTS:
+//   src0 (as):  Expert weight matrices [K, M, n_expert]
+//               - Stack of n_expert matrices, each of size [K, M]
+//   src1 (b):   Activation vectors [K, n_cols, batch]
+//               - n_cols can be 1 (broadcast) or n_expert_used (per-expert inputs)
+//   src2 (ids): Expert selection indices [n_expert_used, batch] (int32)
+//               - For each (slot, batch), specifies which expert from src0 to use
+//
+// OUTPUT:
+//   dst:        Result [M, n_expert_used, batch, 1]
+//
+// COMPUTATION:
+//   For each output position (m, slot, batch):
+//     expert_id = ids[slot, batch]           // Which expert to use (0..n_expert-1)
+//     col_idx = slot % src1.ne[1]            // Which column in src1 (handles broadcasting)

+//       src1[0:K, col_idx, batch]            // Column from activations (may broadcast)
+//     )
+//
+// BROADCASTING:
+//   - When src1.ne[1] == 1: All expert slots use the same activation column
+//   - When src1.ne[1] == n_expert_used: Each slot has its own activation column
+//   - General case: col_idx = slot % src1.ne[1] (modulo handles both cases)
+//
+// MATH NOTATION:
+//   C[m, s, b] = Sum(k=0 to K-1) A[k, m, ids[s,b]] x B[k, s % ne11, b]
+//   where:
+//     m: [0, M)               - output feature index

+// Algorithm:
+// 1. Read row indices from src1 (int64 tensor)
+// 2. For each source row, write it to destination at the specified index
+// 3. Handle type conversion: F32 source -> F32/F16 destination
+// 4. Support multi-dimensional tensor operations

+// As ET is not a cache coherent processor yet SET_ROWS often are setting

+//
+// - distribute work at cacheline granularity
+// - if previous does not work, find the LCM of cacheline size

+// Bare Metal Softmax F32 Kernel
+// Softmax function: y[i] = exp(x[i] - max) / sum(exp(x[j] - max))
+//
+// Algorithm:
+// 1. Apply scaling: x' = x * scale
+// 2. Add mask/bias if present: x' = x' + mask * slope (ALiBi support)
+// 3. Find max value for numerical stability: max = max(x')
+// 4. Compute exponentials: exp_vals[i] = exp(x'[i] - max)
+// 5. Compute sum: sum = sum(exp_vals)
+// 6. Normalize: y[i] = exp_vals[i] / sum
+//
+// Features supported:
+// - Temperature scaling via scale parameter
+// - Attention masking (transformer masks)
+// - ALiBi (Attention with Linear Biases) positional encoding
+// - Numerical stability (subtract max before exp)
+// - ggml broadcasting rules for mask tensors
+//
+// Mask Broadcasting Rules (ggml-specific, not standard numpy):
+// - Dimension 0: mask.ne[0] == input.ne[0] (exact match required)
+// - Dimension 1: mask.ne[1] >= input.ne[1] (allows larger pre-allocated masks)
+// - Dimension 2: input.ne[2] % mask.ne[2] == 0 (modulo broadcasting)
