UpdateStatus UpdateStatus is used by the system to indicate the state of
the debug image info table.
The EFI_DEBUG_IMAGE_INFO_UPDATE_IN_PROGRESS
bit must be set when the table is being modified. Software
consuming the table must qualify the access to the table with
this bit.
The EFI_DEBUG_IMAGE_INFO_TABLE_MODIFIED bit is
always set by software that modifies the table. It may be cleared
by software that consumes the table once the entire table has
been read. It is essentially a sticky version of the
EFI_DEBUG_IMAGE_INFO_UPDATE_IN_PROGRESS bit
and is intended to provide an efficient mechanism to minimize
the number of times the table must be scanned by the consumer.
TableSize The number of EFI_DEBUG_IMAGE_INFO elements in the
array pointed to by EfiDebugImageInfoTable.
EfiDebugImageInfoTable
A pointer to the first element of an array of
EFI_DEBUG_IMAGE_INFO structures.
