Abstract:
|
||
|
|
|
||
|
|
This file contains a structure definition for the ACPI Memory mapped
|
||
|
|
configuration space base address Description Table (MCFG). Any changes
|
||
|
|
to the MCFG table require updating the respective structure count in
|
||
|
|
Mcfg.h and then adding the structure to the MCFG defined in this file.
|
||
|
|
The table layout is defined in Mcfg.h and the table contents are defined
|
||
|
|
in McfgTable.h and Mcfg.h.
