Supported versions & compatibility - Qualcomm Dragonwing Documentation

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: Table: Supported SoCs, machine configurations, and development kits
