.
Please see the ConfigurationTable member of the EFI System Table (gST).
The table entry with the GUID EFI_ACPI_TABLE_GUID should be used. This
will point to the RSDT/XSDT. You can be notified of any updates to the
table by creating an event group with this same GUID (see CreateEventEx())

Subject: [edk2] Pulling in ACPI table information into a UEFI driver( boot
service)
Hi,
Is there a way to access ACPI tables from within a UEFI driver? Can
someone point me to some examples? The spec outlines the ACPI Device Path
but I'm unclear of how to go about using that to read information.. for
example : XSDT/RSDT..
Thanks !
