of the most recent kernels debian has e.g. 4.15.4-1 above
then it will be able to correct install the microcode or whatever it is
called and you don't need a compiler as new as gcc 7.3?
If so that is excellent news indeed.
No chrooting needed there......
Not a sausage of it.
You would have to run the compiler but the kernel source for 4.15.4-1 would
already be in the debian format.
So it should not be that difficult.
