+# Linux driver stack for Arm Ethos-U
+
+The Linux driver stack for Arm Ethos-U provides an example of how a rich
+operating system like Linux can dispatch inferences to an Arm Cortex-M
+subsystem, consisting of an Arm Cortex-M of choice and an Arm Ethos-U NPU.
+
+## Licenses
+
+The kernel drivers are provided under a GPL v2 license. All other software
+componantes are provided under an Apache 2.0 license.
+
+## Building
+
+The driver stack comes with a CMake based build system. Cross compile for an Arm
+CPU can for example be done with the provided toolchain file.
+
+```
+$ mkdir build
+$ cd build
+$ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchain/aarch64-linux-gnu.cmake -DKDIR=<Kernel directory>
+$ make
+```
+
+## DTB
+
+The kernel driver uses the mailbox APIs as a doorbell mechanism.
+
+```

+#
+#
+# - Support for the auto detection of languages through the file ending can be
+#   added using the 'file_ext' command.

+#
+#     Example:

+#
+#     Example:

+#       `macro-open  BEGIN_MESSAGE_MAP`
+#       `macro-close END_MESSAGE_MAP`
