# 内核概述

Qualcomm^®^ Linux^®^ 有助于将 Linux 内核移植和定制到具有 Qualcomm 硬件 SoC 的设备。它使用长期支持 (LTS) Linux 内核 (6.6.x) 和与 Yocto 项目兼容的 GNU 编译器集合 (GCC) 工具链。

Qualcomm^®^ Linux^®^ 内核提供以下与 Qualcomm 平台上的主线 Linux 内核相关的关键功能和改进：

- Qualcomm Linux BSP 专为支持使用 Qualcomm 平台的设备而量身定制。
- 设备树与 Qualcomm Linux 开发套件相对应。
- 提供多种定制编译版本配置以满足您的要求。
- Qualcomm Linux 内核集成到 Yocto 编译系统中。
- Qualcomm Linux 内核与上游 LTS 内核保持一致。增加的 Qualcomm 特定配置将单独维护。
- 支持配置、定制和编译可在使用 Qualcomm 硬件 SoC 产品的设备上刷写和启动的内核镜像。
- 使用 Gunyah™ Hypervisor 软件支持不受信虚拟机的虚拟化。
- 定期 LTS 从相应的 LTS 内核分支合并以获取最新的安全性和稳定性修复。

内核经过集成和调整，可通过 Qualcomm Linux 元数据层支持 Linux。Qualcomm Linux 提供了一种编译和自定义内核软件包和其他软件包的方法，便于根据设备或应用程序需求定义分发版本。
