/** @file

Provides the services required to access a block I/O device during PEI recovery
|
||||
boot mode.
|
||||
|
||||
The Recovery Module PPI and the Device Recovery Module PPI are device neutral.
|
||||
This PPI is device specific and addresses the most common form of recovery
|
||||
media-block I/O devices such as legacy floppy, CD-ROM, or IDE devices.
|
||||
|
||||
The Recovery Block I/O PPI is used to access block devices. Because the Recovery
|
||||
Block I/O PPIs that are provided by the PEI ATAPI driver and PEI legacy floppy
|
||||
driver are the same, here we define a set of general PPIs for both drivers to use.

The MediaInfo structure describes an enumeration of possible block device

types. This enumeration exists because no device paths are actually passed

across interfaces that describe the type or class of hardware that is publishing
|

the block I/O interface. This enumeration will allow for policy decisions
|

in the Recovery PEIM, such as "Try to recover from legacy floppy first,
|
||||
LS-120 second, CD-ROM third." If there are multiple partitions abstracted
|
||||
by a given device type, they should be reported in ascending order; this
|
||||
order also applies to nested partitions, such as legacy MBR, where the
|
||||
outermost partitions would have precedence in the reporting order. The
|
||||
same logic applies to systems such as IDE that have precedence relationships
|
||||
like "Master/Slave" or "Primary/Secondary"; the master device should be

reported first, the slave second.

This PPI produces functions to interpret and execute the PI boot script table.
|
||||
|
||||
This PPI is published by a PEIM and provides for the restoration of the platform's
|
||||
configuration when resuming from the ACPI S3 power state. The ability to execute
|
||||
the boot script may depend on the availability of other PPIs. For example, if
|
||||
the boot script includes an SMBus command, this PEIM looks for the relevant PPI
|
||||
that is able to execute that command.

Restores the platform to its preboot configuration for an S3 resume and
|
||||
jumps to the OS waking vector.
|
||||
|
||||
This function will restore the platform to its pre-boot configuration that was
|
||||
pre-stored in the boot script table and transfer control to OS waking vector.
|
||||
Upon invocation, this function is responsible for locating the following
|
||||
information before jumping to OS waking vector:
|
||||
- ACPI tables
|
||||
- boot script table
|
||||
- any other information that it needs
|
||||
|
||||
The S3RestoreConfig() function then executes the pre-stored boot script table
|
||||
and transitions the platform to the pre-boot state. The boot script is recorded
|
||||
during regular boot using the EFI_S3_SAVE_STATE_PROTOCOL.Write() and
|
||||
EFI_S3_SMM_SAVE_STATE_PROTOCOL.Write() functions. Finally, this function
|
||||
transfers control to the OS waking vector. If the OS supports only a real-mode
|
||||
waking vector, this function will switch from flat mode to real mode before
|
||||
jumping to the waking vector. If all platform pre-boot configurations are
|
||||
successfully restored and all other necessary information is ready, this
|
||||
function will never return and instead will directly jump to the OS waking
|
||||
vector. If this function returns, it indicates that the attempt to resume
|
||||
from the ACPI S3 sleep state failed.
