Platform and method for supporting hibernate operations
First Claim
1. A method comprising:
- invoking a management interrupt in response to a Hibernate request; and
storing platform configuration information into a non-volatile storage location, the platform configuration information including data to indicate whether a next boot sequence for a platform occurs as a deterministic boot sequence or a non-deterministic boot sequence.

Abstract
One aspect of the invention relates to a method for supporting hibernation despite the presence of hot-plugged nodes and non-deterministic boot operations. The method comprises invoking a management interrupt in response to a Hibernate request. The management interrupt is used to obtain and store platform configuration information into a non-volatile storage location. The platform configuration information includes data to indicate whether a next boot sequence for a platform occurs as a deterministic boot sequence or a non-deterministic boot sequence as well as a boot node identifier and a listing of an order in which processors of the platform are initialized.

9. A software stored in platform readable medium executed by at least one processor within a platform, the software comprising:
-
a first software module to invoke a management interrupt in response to a Hibernate request; and
a second software module to store platform configuration information into a non-volatile storage location, the platform configuration information including data to indicate whether a next boot sequence for a platform occurs as a deterministic boot sequence or a non-deterministic boot sequence. - View Dependent Claims (10, 11, 12, 13, 14, 16, 17, 18, 19, 20)

15. A platform comprising:
-
a plurality of hot-plug processor substrates collectively having a plurality of processors, one of the plurality of processors to request the platform to enter into a Hibernate state; and
an input/output (I/O) substrate including a non-volatile memory, the non-volatile memory being loaded with platform configuration information including data to indicate whether a next boot sequence for a platform occurs as a deterministic boot sequence or a non-deterministic boot sequence prior to entering the Hibernate state.
