# 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"`
