Address Name Description
SetupConfigUpdateDxeLightningRidgeEXECB4EntryPoint
UbaDebugPrint

ReadUnaligned64OrAssert
UbaAssert
Globals for UEFI boot/runtime services.
EFI_HANDLE gImageHandle = NULL;
HOB list pointer, cached for use by HOB library functions.
VOID *mHobList = NULL;
UBA protocol interface pointer, obtained via LocateProtocol.
VOID *gUbaProtocolInterface = NULL;
UBA debug print routing function pointer; obtained via
LocateProtocol using the UBA debug protocol GUID.
UBA_DEBUG_PRINT gUbaDebugPrint = NULL;
GUID definitions
EFI_GUID gUbaSlotDataUpdateConfigProtocolGuid =
Slot data update configuration table data.
This structure is published via the UBA protocol to describe the
slot data update configuration for the LightningRidge EX EC B4
UBA_SLOT_DATA_UPDATE_CONFIG mSlotDataUpdateConfig = {
Slot data payload descriptor GUID table
Each entry in this table describes a slot data payload by GUID and
slot data.
typedef struct {
Forward declarations.
EFI_STATUS EFIAPI
Return cached HOB list if already resolved.
if (mHobList != NULL) {
ASSERT if no HOB list entry was found matching the expected GUID.
if (HobList == NULL) {
Read unaligned GUID values from the HOB entries.
CandidateGuid = (EFI_GUID )ReadUnaligned64 ((UINT64 )CandidateHobEntry);
Slot data update payload configuration
The following table defines the GUID and size of each slot data
payload that this driver registers with the UBA protocol.
Payload 1: UBA Slot Data Update Config Table — 32 bytes
Payload 2: UBA Slot Data GUID EXECB4 — 40 bytes
These payloads are installed into the UBA configuration database
during the entry point execution.
Step 1: Initialize UEFI service table pointers.
gImageHandle = ImageHandle;
Step 2: Resolve the HOB list. Required by the HOB library for
subsequent HOB traversal.
GetHobList ();
Step 3: Log the slot data update registration event.
UbaDebugPrint (
Step 4: Locate the UBA protocol interface.
Status = gBS->LocateProtocol (
Step 5: Install slot data update payloads into the UBA database.
PayloadCount = sizeof (mSlotDataPayloads) / sizeof (mSlotDataPayloads[0]);
