ipu7-drivers

This repository supports MIPI cameras through the IPU7 on Intel Lunar Lake platform. There are 4 repositories that provide the complete setup:

• https://github.com/intel/ipu7-drivers - kernel drivers for the IPU and sensors
• https://github.com/intel/ipu7-camera-bins - IPU firmware and proprietary image processing libraries
• https://github.com/intel/ipu7-camera-hal - HAL for processing of images in userspace
• https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api (branch:icamerasrc_slim_api) - Gstreamer src plugin

Content of this repository:

• IPU7 kernel driver
• Kernel patches needed

Dependencies

• INTEL_SKL_INT3472 and OV13B10 should be enabled.

Build instructions:

Three ways are available:

1. Build with kernel source code tree (in-tree build)
2. Build with kernel headers only (out-of-tree build)
3. Build and install by dkms (DKMS build)

1. In-tree build

• Tested with kernel v6.4 only

• Check out kernel

• Apply patches under patch/

• Copy drivers and include folders to kernel source (except Kconfig & Makefile at drivers/media/pci/intel as they are modified by patches in previous step. You can delete them before you copy folders.).

• Enable the following settings in .config

   CONFIG_VIDEO_INTEL_IPU7=m
   CONFIG_IPU_ISYS_BRIDGE=y
   CONFIG_VIDEO_OV13B10=m
   CONFIG_PINCTRL_INTEL_PLATFORM=m
   CONFIG_INTEL_SKL_INT3472=m
  

2. Out-of-tree build

• Requires kernel headers installed on build machine
• To build and install:

   make -j`nproc` && sudo make modules_install && sudo depmod -a

3. Build with dkms

• Register, build and auto install:

   sudo dkms add .
   sudo dkms autoinstall ipu7-drivers/0.0.0
