Abstract

A computing apparatus, including: a hardware platform including a processor and memory; and a system management interrupt (SMI) handler; first logic configured to provide a first container and a second container via the hardware platform; and second logic configured to: detect an uncorrectable error in the first container; responsive to the detecting, generate a degraded system state; provide a degraded state message to the SMI handler; instruct the second container to seek a recoverable state; determine that the second container has entered a recoverable state; and initiate a recovery operation.

First claim

What is claimed is:

1. A computing apparatus, comprising:
a hardware platform comprising a processor and memory; and
a system management interrupt (SMI) handler;
first logic configured to provide a first container and a second container via the hardware platform; and
second logic configured to:
detect an uncorrectable system-level error caused by the first container, wherein the uncorrectable system-level error affects the first container and the second container;
responsive to the detecting, generate a degraded system state;
provide a degraded state message to the SMI handler;
instruct the second container to seek a recoverable state;
determine that the second container has entered a recoverable state; and
after verifying that the second container has entered the recoverable state, initiate a recovery operation.

2. The computing apparatus of claim 1 , wherein the second logic is further configured to set a timeout, and to initiate the recovery operation after expiration of the timeout.

3. The computing apparatus of claim 1 , further comprising a fabric interface, wherein the second logic is further to provide degradation notification to a controller.

4. The computing apparatus of claim 3 , wherein the second logic is further to request the controller to spawn a new instance of a service provided by the first container.

5. The computing apparatus of claim 1 , wherein the recoverable state comprises a state in which the second container can be migrated with minimal data loss.

6. The computing apparatus of claim 5 , wherein the second logic is further configured to migrate the second container.

7. The computing apparatus of claim 1 , further comprising an operating system, further configured to perform a core dump of the first container.

8. The computing apparatus of claim 7 , wherein the operating system is configured to receive machine check architecture (MCA) logging information from the processor.

9. The computing apparatus of claim 7 , wherein the second logic is further configured to notify the operating system of the degraded state of the apparatus.

10. The computing apparatus of claim 1 , wherein the second logic further comprises a configuration interface configured to receive configuration options.

11. One or more tangible, non-transitory computer-readable mediums having stored thereon instructions for providing logic to:
provide a system management interrupt (SMI) handler;
provide a first container and a second container;
detect an uncorrectable system-level error caused by the first container, wherein the uncorrectable system-level error affects the first container and the second container;
responsive to the detecting, generate a degraded system state;
provide a degraded state message to the SMI handler;
instruct the second container to seek a recoverable state;
determine that the second container has entered a recoverable state; and
after verifying that the second container has entered the recoverable state, initiate a recovery operation.

12. The one or more tangible, non-transitory computer-readable mediums of claim 11 , wherein the logic is further configured to set a timeout, and to initiate the recovery operation after expiration of the timeout.

13. The one or more tangible, non-transitory computer-readable mediums of claim 11 , wherein the logic is further to provide degradation notification to a controller via a fabric interface.

14. The one or more tangible, non-transitory computer-readable mediums of claim 13 , wherein the logic is further to request the controller to spawn a new instance of a service provided by the first container.

15. The one or more tangible, non-transitory computer-readable mediums of claim 11 , wherein the recoverable state comprises a state in which the second container can be migrated with minimal data loss.

16. The one or more tangible, non-transitory computer-readable mediums of claim 15 , wherein the logic is further configured to migrate the second container.

17. The one or more tangible, non-transitory computer-readable mediums of claim 11 , wherein the logic is further configured to provide an operating system configured to perform a core dump of the first container.

18. The one or more tangible, non-transitory computer-readable mediums of claim 17 , wherein the operating system is configured to receive machine check architecture (MCA) logging information from the logic.

19. The one or more tangible, non-transitory computer-readable mediums of claim 17 , wherein the logic is further configured to notify the operating system of the degraded state of the first container.

20. The one or more tangible, non-transitory computer-readable mediums of claim 11 , wherein the logic further comprises a configuration interface configured to receive configuration options.

21. A computer-implemented method of providing delayed error processing, comprising:
providing a system management interrupt (SMI) handler;
providing a first container and a second container;
detecting an uncorrectable system-level error caused by the first container, wherein the uncorrectable system-level error affects the first container and the second container;
responsive to the detecting, generating a degraded system state;
providing a degraded state message to the SMI handler;
instructing the second container to seek a recoverable state;
determining that the second container has entered a recoverable state; and
after verifying that the second container has entered the recoverable state, initiating a recovery operation.

22. The method of claim 21 , further comprising setting a timeout, and to initiate the recovery operation after expiration of the timeout.

23. The method of claim 21 , further comprising providing degradation notification to a controller via a fabric interface.

24. The method of claim 23 , further comprising requesting the controller to spawn a new instance of a service provided by the first container.

25. The method of claim 21 , wherein the recoverable state comprises a state in which the second container can be migrated with minimal data loss.
