To address your questions regarding integrating newer kernel drivers with Torizon OS, here are some insights based on the provided context:

  1. Backporting Kernel Modules: Backporting newer kernel modules to an older kernel version like 5.15 can be challenging. It involves adapting the newer module’s code to be compatible with the older kernel’s APIs and infrastructure. You can add the source to your codebase and treat it as a custom kernel module, but this may require significant modifications depending on the changes between kernel versions.

  2. Adding Source to Codebase: If a driver is only available in a newer kernel version, adding its source to your codebase might require additional changes. This is because newer kernel versions might have different APIs or dependencies that are not present in the older kernel version you are using.

  3. Building Torizon OS with a Newer Kernel: The context does not provide specific instructions on building Torizon OS with a newer kernel using TorizonCore Builder. Typically, Torizon OS is provided as a binary distribution, and changing the kernel version would require significant customization and expertise in kernel development.

  4. Timeline for Kernel >=6.6: The context does not provide information on the timeline for when Torizon OS will officially support kernel versions >=6.6. For such information, it would be best to contact Toradex support or check their official release notes and roadmap.

Given these challenges, you might consider reaching out to Toradex support for guidance on backporting specific drivers or inquire about future kernel updates in Torizon OS.
