Qualcomm® Linux® facilitates porting and customizing the Linux kernel to devices with
        Qualcomm chipsets. It uses a long-term support Linux kernel (6.6.x) and the GNU compiler
        collection (GCC) toolchain that is compatible with the Yocto project.

The kernel is integrated and aligned to support Qualcomm Linux through Qualcomm supported
            meta layers. Qualcomm Linux provides a way to build and customize the kernel and other
            packages to define a distribution according to the needs of a device or application.

The following information enables you to understand the procedures to:
