CONFIG_IMX_DSP: IMX DSP Protocol driver

General informations

The Linux kernel configuration item CONFIG_IMX_DSP has multiple definitions:

IMX DSP Protocol driver found in drivers/firmware/imx/Kconfig

The configuration item CONFIG_IMX_DSP:

• prompt: IMX DSP Protocol driver
• type: tristate
• depends on: CONFIG_IMX_MBOX
• defined in drivers/firmware/imx/Kconfig
• found in Linux kernels: 5.6–5.19, 6.0–6.12, 6.13-rc+HEAD
• modules built: imx-dsp

Help text

This enables DSP IPC protocol between host AP (Linux) and the firmware running on DSP. DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).

It acts like a doorbell. Client might use shared memory to exchange information with DSP side.
