[PATCH] i386/x86_64: Check if MCFG works for the first 16 busses

Browse source

Previously only the first bus would be checked against Type 1.

Why 16? Checking all would need too much memory and we
can assume that systems with more than 16 busses have better than
average quality BIOS.

This is an additional defense against bad MCFG tables.
