Using the new kernel on a Raspberry Pi 5. I am not sure if this causes any real issue to other software, but I run btop++ and I have noticed that when running the Linux 6.6 kernel btop++ prints "Cortex A76" above the CPU graph on the right hand side. When running the 6.12 kernel the name is missing. It is not a big deal for btop++, but I was wondering why it is having trouble identifying the CPU. If I get a chance on the weekend I might have a look at the source for btop++ and try to work out where it is getting the name from.
Edit: I worked this out. The btop program looks for "/proc/devices/arm..." and parses that directory name for "Cortex ...". On Linux 6.12 this is now in "/sys/devices/platform/arm-pmu/arm...". So a problem for the btop developers nothing to do with the Raspberry Pi.
