Abstract:
A mechanism for providing non-volatile memory for suspend-to-RAM in a computer system. A method includes searching for a checkpoint message in a memory upon receipt of notification of restoring of power in a system. The checkpoint message is a confirmation of storing of state of a storage device prior to loss of the power in the system. The method also includes determining whether the checkpoint message indicates that the system reached the power integrity checkpoint. The power integrity checkpoint is a confirmation of the storing of the state of other device prior to the loss of the power in the system. The other device is different from the storage device. The method further includes restoring operating conditions of the system when it is determined that the system has reached the power integrity checkpoint.
