Hi, I would like to learn more of the above matter. After the MCFG table gets discovered with acpi, what does the address given by the ACPI_MCFG_ALLOCATION* tells you? Does that tell you the address of the extended configuration space of pci express? Also, is BSD distinguishing between reading from pcie config & pci config? Because there's this pciereg_cfgread() function that seem to do that. I thought pcie config space is just at the offset of 0x100 from pci config space? -- Thanks in advance, ~Hilfi Alkaff~
