+## Overview
+
+The document covers procedures for installing the latest GPU and NPU drivers, and OpenCL and Hexagon SDKs.
+
+
+In order to use Hexagon NPU on Snapdragon Windows devices the underlying HTP Ops libraries (e.g libggml-htp-v73.so)
+must be included in the .cat file digitally signed with a trusted certificate.
+
+This document covers details on how to generate personal certificate files (.pfx) and how to configure the system
+to allow for test signatures (aka test-signing).
+
+## Install the latest Adreno OpenCL SDK
+
+Either use the trimmed down version (optimized for CI) from
+
+    https://github.com/snapdragon-toolchain/opencl-sdk/releases/download/v2.3.2/adreno-opencl-sdk-v2.3.2-arm64-wos.tar.xz
+
+Or download the complete official version from
+
+    https://softwarecenter.qualcomm.com/catalog/item/Adreno_OpenCL_SDK?version=2.3.2
+
+Unzip/untar the archive into
+```
+c:\Qualcomm\OpenCL_SDK\2.3.2
+```
+
+## Install the latest Hexagon SDK Community Edition
+
+Either use the trimmed down version (optimized for CI) from
+
+    https://github.com/snapdragon-toolchain/hexagon-sdk/releases/download/v6.4.0.2/hexagon-sdk-v6.4.0.2-arm64-wos.tar.xz
+
+Or download the complete official version from
+
+    https://softwarecenter.qualcomm.com/catalog/item/Hexagon_SDK?version=6.4.0.2
+
+Unzip/untar the archive into
+```
+c:\Qualcomm\Hexagon_SDK\6.4.0.2
+```
+
+## Install the latest Adreno GPU driver
+
+Download the driver from
+
+    https://softwarecenter.qualcomm.com/catalog/item/Windows_Graphics_Driver
+
+After the automated installation and reboot please make sure that the GPU device shows up in the `Device Manager` (under 'Display Adapters`)
+
+## Install the latest Qualcomm NPU driver
+
+Download the driver from
+
+    https://softwarecenter.qualcomm.com/catalog/item/Qualcomm_HND
+
+After the automated installation and reboot please make sure that the Hexagon NPU device shows up in the `Device Manager` (under `Neural Processors`).
+
+If the device is not available you can try installing all components (`qcnspmcdm8380`, `qcnspmcdm8380_ext`) manually.
+The components are extracted into
+```
+c:\QCDrivers\qcnspmcdm...
+```
+
+## Enable NPU driver test signatures
+
+Please note that the following steps are required only for the Hexagon NPU.
+Adreno GPU backend does not require test signatures.
+
+### Enable testsigning
+
+Use `bcdedit` to enable test-signing
+```
+> bcdedit /set TESTSIGNING ON
+```
+(Secure Boot may need to be disabled for this to work)
+
+Make sure test-signing is enabled after reboot
+```
+> bcdedit /enum
+...
+testsigning             Yes
+...
+```
+For additional details see Microsoft guide at
+
+   https://learn.microsoft.com/en-us/windows-hardware/drivers/install/the-testsigning-boot-configuration-option
+
+### Create personal certificate
+
+The tools required for this procedure are available as part of Windows SDK and Windows Driver Kit which should be
+installed as part of the MS Visual Studio.
+They are typically located at
+```
+c:\Program Files (x86)\Windows Kits\10\bin\10.0.26100.0
+```
+(replace 10.0.26100.0 with correct version).
+
+To create personal self-signed certificate run the following commands (either from cmd or power-shell):
+```
+> cd c:\Users\MyUser
+> mkdir Certs
+> cd Certs
+> makecert -r -pe -ss PrivateCertStore -n CN=GGML.HTP.v1 -eku 1.3.6.1.5.5.7.3.3 -sv ggml-htp-v1.pvk ggml-htp-v1.cer
+> pvk2pfx.exe -pvk ggml-htp-v1.pvk -spc ggml-htp-v1.cer -pfx ggml-htp-v1.pfx
+```
+(replace `MyUser` with your username).
+
+Add this certificate to `Trusted Root Certification Authorities` and `Trusted Publishers` stores.
+This can be done using `certlm` Certificate Manager tool.
+Right click on the certificate store, select `All Tasks -> Import` and follow the prompts to import the certificate from the
+PFX file you created above.
+
+For additional details see Microsoft guide at
+
+    https://learn.microsoft.com/en-us/windows-hardware/drivers/install/introduction-to-test-signing
+
+Make sure to save the PFX file, you will need it for the build procedures.
+Please note that the same certificate can be used for signing any number of builds.
+
+## Build Hexagon backend with signed HTP ops libraries
+
+The overall Hexagon backend build procedure for Windows on Snapdragon is the same as for other platforms.
+However, additional settings are required for generating and signing HTP Ops libraries.
+```
+> $env:OPENCL_SDK_ROOT="C:\Qualcomm\OpenCL_SDK\2.3.2"
+> $env:HEXAGON_SDK_ROOT="C:\Qualcomm\Hexagon_SDK\6.4.0.2"
+> $env:HEXAGON_TOOLS_ROOT="C:\Qualcomm\Hexagon_SDK\6.4.0.2\tools\HEXAGON_Tools\19.0.04"

+
+> cmake --preset arm64-windows-snapdragon-release -B build-wos

 The environment variable [`CUDA_SCALE_LAUNCH_QUEUES`](https://docs.nvidia.com/cuda/cuda-programming-guide/05-appendices/environment-variables.html#cuda-scale-launch-queues) controls the size of CUDA's command buffer, which determines how many GPU operations can be queued before the CPU must wait for the GPU to catch up. A larger buffer reduces CPU-side stalls and allows more work to be queued on a GPU.
 
-**Default behavior:** llama.cpp automatically sets `CUDA_SCALE_LAUNCH_QUEUES=4x`, which increases the CUDA command buffer to 4 times its default size. This optimization is particularly beneficial for **Multi-GPU setups with pipeline parallelism**, where it significantly improves prompt processing throughput by allowing more operations to be enqueued across GPUs.

+### n-gram Mod (`ngram-mod`)
+
+Add basic ngram hasher for speculative decoding:
+
+- For each ngram, compute a hash using LCG
+- For each computed hash, store the next token
+- During speculation, iteratively compute the rolling hash of the last n tokens and pick the next token from the storage
+
+Some characteristics:
+
+- Lightweight (~16 MB)
+- Constant memory and complexity
+- Can generate variable draft lengths (i.e. m is not fixed)
+
+Currently, a single hash pool is shared across all server slots, so different requests can benefit from each other.
+
+**Sample usage:**
+
+```
+# notes:
+# - small `n` are not recommended
+# - MoEs require long drafts
+# - dense models: can reduce `--draft-min` and `--draft-max`
+
+llama-server ... --spec-type ngram-mod --spec-ngram-size-n 24 --draft-min 48 --draft-max 64
+```
+
+Applications:
+
+- Iterating over a block of text/code (e.g. in llama.vim)
+- Reasoning models (when they have to repeat their thinking in the final answer)
+- Summarization
+
+Example Video:
+
+- See #19164
+
+### Differences between ngram-simple, ngram-map and ngram-mod
+
+- ngram-simple looks for a previous matching n-gram and inserts the following m-gram.
+- ngram-map-k looks for a previous matching n-gram and inserts the following m-gram but uses an internal hash-map of n-grams in the current context window.
+- ngram-mod uses a hash pool which is shared across all server slots. The hash pool is a map from n-gram hash to the next token (not the next m-gram as in ngram-map).
 
 ## Command-Line Options
 
 If a draft model is combined with a draftless decoding the draftless decoding has higher precedence.
