And when I originally wrote this it was purely a hack to debug an issue for myself, and used a different type of logging device altogether. But yeah, if this were to be used on bare metal 16550A it would indeed need to wait for space in the FIFO/THR. > What is the point of writing this code in assembly in the first place?

It isn't like it is in any shape, way or form performance critic= al. If we fix it up to use a proper linker script, that's slightly more feasible.=C2=A0As things stand, it's only really possible to do it in the existing asm file.=20 And it's only the core of the exception handler "function" which could be moved out to C; it didn't seem particularly worth bothering. Would be nice to have the IDT generated from C code *before* calling relocate_kernel() instead of inside relocate_kernel itself, perhaps, but I was also trying to keep the #define DEBUG version of the code fairly self-contained. --=-lqAHLn5mSGAKaJX2S/MD Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64
