Reference for Qualcomm® Linux kernel versions, Yocto release compatibility,
and supported hardware SoCs and development kits.
Kernel versions
The Qualcomm Linux kernel is available in two tracks:
Table: Kernel tracks
| Track | Description | Yocto recipe |
|---|
| LTS (Long-Term Support) | Based on the upstream LTS kernel v6.18.x. Recommended for production use. Qualcomm-specific additions are maintained separately and periodic LTS merges bring in the latest security and stability fixes. | linux-qcom_6.18.bb |
| Mainline | Tracks the upstream mainline kernel. Intended for upstream development and contribution workflows. | linux-qcom-next_git.bb |
The LTS kernel is selected by default in the meta-qcom base configuration:
PREFERRED_PROVIDER_virtual/kernel = "linux-qcom"
PREFERRED_VERSION_virtual/kernel = "6.18%"
For the mainline kernel, PREFERRED_VERSION_virtual/kernel is left empty.
Yocto compatibility
Table: Yocto release compatibility
| Yocto codename | Manifest branch | Release tag format |
|---|
| wrynose | qcom-linux-wrynose | qli-<version> (for example, qli-2.0) |
The meta-qcom layer is the primary Qualcomm Yocto meta-layer. Releases are tagged
using the qli-<version> convention in the
quic-yocto/qcom-manifest repository.
For host setup and manifest sync instructions, see the
BSP image build with firmware.
Supported hardware SoCs and development kits
The following table lists the SoCs, their Yocto machine configuration names,
and the associated development kits supported in this release:

Machine configuration files follow the <SoC>-<board>-<variant>.conf naming
convention and are located in meta-qcom/conf/machine/.
