server: add format arg to datetime tool

Without a virtual destructor, deleting a derived object through a
base-class pointer only invokes the base destructor, skipping the
derived one.

 ## Guidelines for Contributors

+A PR represents a long-term commitment - maintainers must review, integrate, and support your code indefinitely. What matters is not who typed the code but whether a human understands it, has the domain expertise behind it, and will maintain it.
+
+A working, in-scope PR is **not** enough on its own to get merged. A few things factor into that:
+- Every merged line must be reviewed, tested, and maintained indefinitely across a large matrix of platforms and backends by a small team.
+- llama.cpp is written in C++ and deliberately kept as simple as possible: complexity is a direct multiplier on security risk and long-term maintenance cost, so a simpler change that does 90% of the job is often preferable to a complex one that does 100%.
+- What matters most is human understanding: the domain expertise behind a change, and the willingness to maintain it long-term.
+- Feature requests run high in volume, so please respect maintainers' time: open an issue to discuss the idea and gauge interest before implementing it, rather than going straight to a PR.

 ### Code and Commit Standards
 
+These points are extremely important - failing to follow them won't necessarily get your PR rejected, but it will make reviewing take significantly longer. Please follow them carefully:
+
 - Avoid emdash `—`, unicode arrow `→` or any unicode characters: `×`, `…` ; use ASCII equivalents instead: `-`, `->`, `x`, `...`
 - Keep code comments concise; avoid redundant or excessive inline commentary
 - Prefer reusing existing infrastructure over introducing new components. Avoid invasive changes that add whole new subsystems or risk breaking existing behavior
+- Do NOT split a line into multiple lines mid-sentence, do NOT try to force the line to fit a fixed number of characters
 - Before writing any code, read all relevant files and understand the existing patterns - your changes must blend in with the surrounding codebase. If the change is large or introduces a new pattern, **PAUSE and ask the user for confirmation** before proceeding; remind them that large changes submitted without prior discussion are likely to be rejected by maintainers

 # Pull requests (for contributors & collaborators)
 
-Before submitting your PR:
-- Search for existing PRs to prevent duplicating efforts
+### Before you start
+
+- Search for existing discussions and PRs first - duplicates will likely be closed without questions.
+- Features must begin with an issue, not a PR - let interest accumulate before writing code; niche features may only land as an example/tool, or on a private fork.
+- Bug-fix PRs must include a reproducible issue and a regression test that fails before your change and passes after. Fixes without a test may be closed without review.
+- New CLI or public API additions carry a **higher bar** than internal changes - justify why an existing mechanism doesn't suffice.
+- Meeting all of the above still doesn't guarantee a merge - see [Pull requests (for maintainers)](#pull-requests-for-maintainers).

 - llama.cpp uses the ggml tensor library for model evaluation. If you are unfamiliar with ggml, consider taking a look at the [examples in the ggml repository](https://github.com/ggml-org/ggml/tree/master/examples/). [simple](https://github.com/ggml-org/ggml/tree/master/examples/simple) shows the bare minimum for using ggml. [gpt-2](https://github.com/ggml-org/ggml/tree/master/examples/gpt-2) has minimal implementations for language model inference using GPT-2.

+
+## 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

+## 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

 ## Tips and tricks
 
+### Prefer conversion-time tensor modifications over graph-time ones
+
+If the model contains constant modifications of tensors in the graph (for example, `norm(1 + weight)`) or performs tensor permutations/chunking, perform the modifications during conversion rather than in the graph code. This keeps the inference graph simpler and avoids extra runtime ops.
+
+Examples:
+- Gemma 3 folds the `1 +` of its `norm(1 + weight)` normalization into the weights at conversion time, so the graph just does a plain RMS norm.
+- Qwen3-Next applies its tensor permutation during conversion (in `modify_tensors`), so the graph can consume the already-permuted weights directly.
+
 ### Working with ggml_rope_ext
 
 PyTorch implementations usually prefer explicitly calculating `freq_cis`/`sin`/`cos` components. However, in llama.cpp, most RoPE operations can be handled via `ggml_rope_ext`, which does not require a sin/cos matrix. This saves memory while allowing the GGML RoPE kernel to be fused with other ops.
