# Getting started This section explains how to develop software using Qualcomm Linux. Before you begin, set up your infrastructure as described in [Qualcomm Linux Build Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-254/introduction.html). This guide also provides information about the common build workflow. ## Prepare performance build You can enable SSH in Permissive mode. For instructions see [Log in using SSH](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-254/how_to.html#use-ssh). The default Qualcomm build is the performance build. For any power measurement, it is recommended to use the performance build. The performance build uses the following kernel configurations: `kernel_platform/kernel/arch/arm64/configs/qcom_defconfig` `kernel_platform/kernel /arch/arm64/configs/qcom_addons.config` The kernel configurations are defined in the source code kernel recipe at: `layer/meta-qcom-hwe/recipes‑kernel/linux/linux-kernel-qcom_6.6.bb.` `KERNEL_DEFCONFIG = "${S}/arch/arm64/configs/qcom_defconfig"` `KERNEL_CONFIG_FRAGMENTS:append = " ${S}/arch/arm64/configs/qcom_addons.config"` Last Published: Jan 26, 2025 [Previous Topic Overview](https://docs.qualcomm.com/bundle/publicresource/80-70017-30/topics/poweroverview.md) [Next Topic Architecture](https://docs.qualcomm.com/bundle/publicresource/80-70017-30/topics/architecture.md)
