# `meta-qcom-extras`

This layer is an optional metadata layer for registered users. This
layer allows source compilation of select components, which are
otherwise present as binaries in `meta-qcom-hwe`. If you are entitled to
receive this metadata layer, you can use the steps shared in the
[Qualcomm Linux Build
Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-254/build_addn_info.html).

## Firmware recipes

The `meta-qcom-extras` layer provides recipe append files for the
firmware recipes defined in `meta-qcom-hwe` layer at `meta-qcom-hwe/recipes-firmware/firmware`.
The following code snippet shows these recipe append files, with extension `.bbapend`.
The firmware recipe append files have the `SRC_URI` set to zip files that you may want to use
instead of the default zip files distributed with this Qualcomm Linux release.

Follow the [Qualcomm Linux Build Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70029-254/build_addn_info.html)
to build cDSP, aDSP, boot firmware, and generate the zip file that you can integrate using the provided recipe append files.
