Byte sizes of different kernels for my laptop. Everything needed built-in, except for wifi modules. Same compiler, roughly same kernel configs: 6906816 vmlinuz-4.9.284 7603200 vmlinuz-4.19.208 8306752 vmlinuz-5.10.69 > Figuring that out would be good as you only have 1 more year for 4.9.y > to be alive, that's not going to last for forever... I will deal with that when 4.9.y updates run dry, or when Raspbian userland starts requiring newer kernel. -- Jari Ruusu 4096R/8132F189 12D6 4C3A DCDA 0AA4 27BD ACDF F073 3C80 8132 F189
