+Direct hardware access via PCIe ECAM (Enhanced Configuration Access Mechanism).
+Available on all PCIe-compliant hardware. Requires root privileges and access
+to physical memory (on Linux systems disabled CONFIG_STRICT_DEVMEM option). On
+ACPI compatible systems is ECAM mapping read from the MCFG table specified by the
+.B ecam.acpimcfg
+parameter. On EFI compatible systems, ACPI MCFG table can be located in physical
+memory via EFI system table specified by the
+.B ecam.efisystab
+parameter. On FreeBSD/NetBSD systems, physical address of ACPI MCFG table can be
+located by kenv or sysctl interface when the
+.B ecam.bsd
+parameter is not disabled. On x86 BIOS compatible systems, ACPI MCFG table can
+be located in physical memory by scanning x86 BIOS memory when the
+.B ecam.x86bios
+parameter is not disabled. Alternatively ECAM mappings can be specified by the
+.B ecam.addrs
+parameter which takes precedence over ACPI MCFG table. This option is required
+on systems without ACPI and also on systems without EFI or x86 BIOS.
