|

|

|
||||
## 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)
|
||||
- Llama 3.1 model family.
|
||||
- RWKV v7 model family.
|
||||
- TinyLLaMA
|
||||
|
||||
|
||||
## 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`:
|
||||
|
||||
```
|
||||
ET_PERF|op=MUL_MAT|kernel=mul_mat_f32_Q8_0xf32|duration_us=3112|tensor=Qcur-0|shape=[4096,2,1,1]|start_us=48437862009|end_us=48437865121|flops=67100672
|
||||
ET_PERF|op=ROPE|kernel=rope_f32|duration_us=9266|tensor=Qcur-0|shape=[128,32,2,1]|start_us=48437865128|end_us=48437874394|mode=0x0|n_dims=128|freq_base=500000.00|freq_scale=1.00
|
||||
```
|
||||
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

// 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 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)
|
||||
// dst[m, slot, batch] = dot_product(
|
||||
// src0[0:K, m, expert_id], // Row m from selected expert matrix
|
||||
// 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
|
||||
// s: [0, n_expert_used) - expert slot index
|
||||
// b: [0, batch) - batch index
|
||||
// k: [0, K) - hidden dimension
|
||||
// ne11 = src1->ne[1] - number of columns in src1
