When initiating Qualcomm Linux builds, set the `QCOM_SELECTED_BSP` variable to either `custom` or `base`. This variable is defined in `conf/machine/include/qcom-base.inc` and is set to `custom` by default as follows: QCOM_SELECTED_BSP ??= "custom" Copy to clipboard The value set for `QCOM_SELECTED_BSP` translates into two BitBake OVERRIDES. The following is a mapping table of `QCOM_SELECTED_BSP` to the corresponding BitBake OVERRIDE: | `QCOM_SELECTED_BSP` value | Corresponding BitBake OVERRIDE | | --- | --- | | `base` | `qcom-base-bsp` | | `custom` | `qcom-custom-bsp` | The effective value of the BitBake OVERRIDE sets variables selectively, resulting in inclusion of packages in the image. Note To familiarize yourself with BitBake OVERRIDES, see [Conditional syntax (Overrides)](https://docs.yoctoproject.org/bitbake/2.8/bitbake-user-manual/bitbake-user-manual-metadata.html#conditional-syntax-overrides) and [Yocto Project documentation](https://docs.yoctoproject.org/singleindex.html#term-OVERRIDES). To utilize the `base` variant of the BSP and how to set `QCOM_SELECTED_BSP` at build time, see [Build base image](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-254/github_workflow_unregistered_users.html#build-base-image). Note In this release, the `base` BSP supports Qualcomm reference devices for building with `qcs8300-ride-sx.conf`, `qcs9075-ride-sx.conf`, `qcs9100-ride-sx.conf`. The final image composition depends on whether you choose `base` or `custom` value for the `QCOM_SELECTED_BSP` variable, see [Overview](https://docs.qualcomm.com/doc/80-70018-27/topic/overview.html#yocto-overview). To find examples of how these OVERRIDES select the software components to be built, search the `meta-qcom-hwe` codebase using `qcom-base-bsp` and `qcom-custom-bsp`. ### meta-qcom The `meta-qcom` metadata layer is hosted at [git.yoctoproject.org](http://git.yoctoproject.org) and provides recipes to build the Qualcomm OSS. Build the software image using the following recipes from the `meta-qcom` layer. | `recipes-devtools/qdl/qdl_git.bb` | The Qualcomm Download (QDL) flashing tool communicates
with the USB devices displaying ID 05c6:9008 to upload a flash
loader and uses this recipe to flash the images. | | --- | --- | | `recipes-support/pd-mapper/pd-mapper_git.bb` | The Qualcomm pd-mapper is an implementation for the
protection domain mapper service. This service configures and
manages protection domains, ensuring secure communication
between applications and various remote processors. | | `recipes-support/qrtr/qrtr_git.bb` | The Qualcomm Router (QRTR) is an inter-process communication mechanism
used in Qualcomm SoCs. It allows communication between different processors in the system,
like the application processor and the modem, using a socket-style programming interface in the user space. | | `recipes-support/initrdscripts/initramfs-module-copy-modules_1.0.bb` | `initramfs-framework` module for copying kernel modules from
`initramfs` to `rootfs`. | ### meta-qcom-hwe The `meta-qcom-hwe` metadata layer is available on [GitHub](https://github.com/qualcomm-linux/meta-qcom-hwe/tree/scarthgap). It provides additional software support for enabling Qualcomm devices. > > > - **BitBake classes** > > > For an introduction to the BitBake classes, > see [Classes](https://github.com/qualcomm-linux/meta-qcom-hwe/tree/scarthgap/classes). > > > > > > > | File | Description | > | --- | --- | > | `classes/qprebuilt.bbclass` | Implements logic to use a prebuilt package instead of fetching and
compiling the source. For any recipe inheriting **qprebuilt**,
this class unpacks the binary packed in a tar.gz archive
and provides these binaries for packaging using a BitBake task. | > | `classes/qmodule.bbclass` | By default, the Qualcomm BSP enforces signing the kernel module by
enabling `CONFIG_MODULE_SIG_FORCE` in the kernel.
However, some out-of-tree modules may not be signed.
To avoid module loading issues, `qmodule.bbclass` inspects
all packages providing kernel modules and signs them if they’re
not already signed. | > | `classes/image_types_ota_sdboot.bbclass` | This BitBake class implements image creation according to requirements

| | | | | | | To learn more about the supported combinations for building Qualcomm Linux, see [Qualcomm Linux Release Notes](https://docs.qualcomm.com/bundle/publicresource/topics/RNO-250403001134). For detailed build instructions, see [GitHub workflow for unregistered users](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-254/github_workflow_unregistered_users.html). ### meta-qcom-realtime The `meta-qcom-realtime` metadata layer is available on [GitHub](https://github.com/qualcomm-linux/meta-qcom-realtime). This layer provides additional software support for building a real-time kernel for Qualcomm devices. - **Kernel recipes** Qualcomm Linux supports the LTS Qualcomm Linux kernel v6.6.x and real-time extensions. It’s maintained through the `linux-qcom-custom-rt_6.6.bb` and `linux-qcom-base-rt_6.6.bb` Yocto recipes at `recipes-kernel/linux` under the `meta-qcom-realtime` layer. The pending pre-empt RT patches can be found at [realtime](https://wiki.linuxfoundation.org/realtime/start). These patches are fetched and applied on top of the `linux-qcom-custom-rt_6.6.bb`, which is publicly hosted at [Codelinaro](https://git.codelinaro.org/clo/la/kernel/qcom.git). To compile a real-time kernel for Qualcomm devices: > > > - If you chose the `custom` OVERRIDE, `conf/layer.conf` selects `linux-qcom-custom-rt`. > - If you chose the `base` OVERRIDE, `conf/layer.conf` selects `linux-qcom-base-rt`. **Kernel configuration** Both recipes append the `qcom_rt.cfg` fragment as follows: KERNEL_CONFIG_FRAGMENTS:append = " ${WORKDIR}/qcom_rt.cfg" Copy to clipboard - **Enable** `meta-qcom-realtime` **in build** To include `meta-qcom-realtime` in the build, export the `meta-qcom-realtime` layer to EXTRALAYERS in `bblayers.conf`, as described in the following steps: 1. Source the environment. The following is an example to source the environment for a QCS6490-based machine and the `qcom-wayland` distribution: MACHINE=qcs6490-rb3gen2-core-kit DISTRO=qcom-wayland source setup-environment Copy to clipboard 2. Open the `build-qcom-wayland/conf/bblayers.conf` file and update the EXTRALAYERS variable as follows. EXTRALAYERS ?= " \ ${WORKSPACE}/layers/meta-qcom-realtime \ " Copy to clipboard 3. Run the build command to rebuild with `meta-qcom-realtime` as follows: bitbake qcom-multimedia-image Copy to clipboard ### 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/80-70018-254/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/80-70018-254/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. | recipes-firmware
└── firmware
├── firmware-qcom-bootbins_1.0.bbappend
├── firmware-qcom-dspso_1.0.bbappend
├── firmware-qcom-hlosfw_1.0.bbappend
└── firmware-qcom-partconf_1.0.bbappend
Copy to clipboard | The recipes in `meta-qcom-extras` override the `SRC_URI` in recipes from `meta-qcom-hwe`.
The `meta-qcom-hwe` layer uses pre-built firmware binaries by default, while
the `meta-qcom-extras` layer builds the firmware zip provided by the user.


The `meta-qcom-extras` layer ignores the pre-built binaries from the default
.zip files. These recipes instead search for user-provided .zip files set
in FWZIP\_PATH as follows:



>
>
>

    >

  • firmware-qcom-bootbins_1.0.bbappend: Searches for the zip archive under the path defined by the variable FWZIP_PATH.


    • >

  • firmware-qcom-hlosfw_1.0.bbappend: Searches for the zip archive under the path defined by the variable FWZIP_PATH.


    • >

  • firmware-qcom-dspso_1.0.bbappend: Searches for the zip archive under the path defined by the variable FWZIP_PATH.


    • >

  • firmware-qcom-partconf_1.0.bbappend: Searches for the zip archive under the path defined by the variable FWZIP_PATH.

| | --- | --- | ### meta-qcom-qim-product-sdk - **BitBake classes** The following table lists the BitBake classes defined in the `meta-qcom-qim-product-sdk` metadata layer: | BitBake class | Description | | --- | --- | | `qim-prod-sdk-pkg.bbclass` |

  • Provides a packaging task to pack the Qualcomm Intelligent Multimedia Product (QIMP) SDK artifacts
    into an archive. It’s invoked by the qim-product-sdk recipe.


  • The easy-to-install artifact archives are available in the
    <workspace>/build-qcom-wayland/tmp-glibc/deploy/qim_prod_sdk_artifacts
    directory after the recipe build is complete.


| | `qimsdk-pkg.bbclass` |

  • Provides a task to package the Qualcomm Multimedia SDK packages into an
    archive along with an easy-to-use install script. The archives are
    generated with packages to develop, deploy, and debug separately.


  • The easy-to-install artifact archives are available in the
    <workspace>/build-qcom-wayland/tmp-glibc/deploy/qimsdk_artifacts directory.


  • Invoked by the qim-sdk recipe during the build.


| | `tflitesdk-pkg.bbclass` |

  • Provides a packaging task to pack the Lite Runtime SDK artifacts into several
    archives to develop, deploy, and debug. It’s invoked by the
    tflite-sdk recipe during the build.


  • The easy-to-install artifact archives are available in the
    <workspace>/build-qcom-wayland/tmp-glibc/deploy/qim_prod_sdk_artifacts
    directory after the recipe build is complete.
