Variable Architectural Protocol as defined in PI Specification VOLUME 2 DXE

|
||||
This code is used to produce the UEFI 2.0 runtime variable services
|
||||
This provides the services required to get and set environment variables. This
|
||||
protocol must be produced by a runtime DXE driver and may be consumed only by
|
||||
the DXE Foundation. The DXE driver that produces this protocol must be a runtime
|
||||
driver. This driver is responsible for initializing the GetVariable(),
|
||||
GetNextVariableName(), and SetVariable() fields of the UEFI Runtime Services Table.
|
||||
|
||||
The GetVariable (), GetNextVariableName (), and SetVariable () UEFI 2.0
|
||||
services are added to the EFI system table and the
|
||||
EFI_VARIABLE_ARCH_PROTOCOL_GUID protocol is registered with a NULL pointer.
|
||||
|
||||
No CRC of the EFI system table is required, as it is done in the DXE core.
|
||||
After the three fields of the UEFI Runtime Services Table have been initialized,
|
||||
the driver must install the EFI_VARIABLE_ARCH_PROTOCOL_GUID on a new handle with
|
||||
a NULL interface pointer. The installation of this protocol informs the DXE Foundation
|
||||
that the read-only and the volatile environment variable related services are
|
||||
now available and that the DXE Foundation must update the 32-bit CRC of the UEFI
|
||||
Runtime Services Table. The full complement of environment variable services are
|
||||
not available until both this protocol and EFI_VARIABLE_WRITE_ARCH_PROTOCOL are
|
||||
installed. DXE drivers that require read-only access or read/write access to volatile
|
||||
environment variables must have this architectural protocol in their dependency
|
||||
expressions. DXE drivers that require write access to nonvolatile environment
|
||||
variables must have the EFI_VARIABLE_WRITE_ARCH_PROTOCOL in their dependency
|
||||
expressions.
