The free Raspberry Pi KernelCare patching service provided by TuxCare updates the Linux kernel running on R-pi based systems without disruption or downtime. With TuxCare, enthusiasts’ projects can enjoy the same ease of use and security that thousands of professional installations using TuxCare already experience but at no cost.
KernelCare is a live patching technology that supports the application of patches to an actively running Linux kernel without requiring reboots. Using it for your non-commercial Raspberry Pi projects is free and helps keep your projects secure and disruption-free.
Yes, free as in beer. Because we use the same KernelCare IoT capabilities as for our commercial offerings, you’ll have to register to get your license. Still, you won’t receive follow-up by sales or marketing emails (unless you want us to send them).
Currently, we support Ubuntu Focal Fossa on ARM64, with Debian and Raspbian support coming soon. The currently supported chips are ARMv8: BCM2711, and particularly BCM2837.
The Raspberry Pi is just another Linux platform supported by TuxCare Live Patching Services. The live patching process is conceptually easy and totally automatic. You just load the new code into memory, identify the affected functions, pause the processes using these functions, change the pointers to the new code, and resume the processes. This happens transparently and without killing any processes.
