  • Getting into kernel development is daunting due to layers of knowledge without a clear roadmap.
  • Collabora, commissioned by Google, wrote a guide to help newcomers debug kernel issues, published with Linux 6.13.
  • The guide is structured into general debugging tools and specific cases, focusing on multimedia drivers.
  • Example debug command: `echo 0xff > /sys/class/video4linux/video3/dev_debug` for enabling debug on video3 device.
  • The guide aims to simplify debugging for media drivers and encourages reaching out for further assistance.
