# Overview Qualcomm^®^ Linux^®^ facilitates porting and customizing the Linux kernel to devices with Qualcomm chip products. It uses a long-term support (LTS) 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 Linux through Qualcomm Linux 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.  **Figure: Qualcomm Linux kernel workflow** The Qualcomm Linux distribution supports the following chip products and development kits: > > > Table: Supported chip products and development kit > > > | Chipset | Supported device | > | --- | --- | > | QCS6490 |
