Computing platform performance management with RAS services
View Patent ↗In some embodiments, a PPM interface may be provided with functionality to facilitate to an OS RAS services for one or more hardware components, regardless of a particular platform hardware configuration, as long as the platform hardware and OS are in conformance with the PPM interface.
1. A computing platform, comprising:
a non-volatile memory having a firmware boot program; and
a processor to execute the firmware boot program when the processor is reset, the firmware boot program including instructions is to create Performance and Power Management (PPM) interface data structures including a Reliability Accessibility Serviceability (RAS) table structure, wherein the RAS table structure comprises a table for a RAS table format which is compatible with an Advanced Configuration and Power Interface (ACPI) implementation.
2. The computing platform of claim 1 , in which the RAS table structure comprises a table for a RAS features (RASF) platform communication channel (PCC) shared memory region.
3. The computing platform of claim 2 , in which the RAS table structure comprises a table for PCC command codes used by a RASF PCC structure.
4. The computing platform of claim 1 , in which the RAS table structure comprises a table for identifying RAS capabilities bitmap.
5. The computing platform of claim 1 , in which the RAS table structure comprises a table for indicating parameter block structure for a PATROL SCRUB task.
6. The computing platform of claim 1 , in which the RAS table structure comprises a table for indicating a parameter block structure for one or more commands to indicate, to an Operating System (OS), reliability information for memory.
7. The computing platform of claim 6 , in which the reliability information pertains to available reliable flash memory write cycles.
8. The computing platform of claim 1 , in which the boot program comprises an Extensible Firmware Interface (EFI) program.
9. A computing platform, comprising:
a first memory storage device having instructions for an operating system (OS) including OS Performance and Power Management (PPM) components for a PPM interface; and
a second memory storage device, coupled to the first memory storage device via at least one integrated circuit, the second memory storage device having instructions for a firmware boot program including firmware PPM components for a PPM interface, the OS and firmware PPM instructions, when executed, are to establish a PPM interface between the OS and platform hardware, wherein the PPM interface includes a Reliability Accessibility Serviceability (RAS) data structure, to provide to the OS, RAS services.
10. The computing platform of claim 9 , in which the OS is to identify available RAS services from the RAS data structure.
11. The computing platform of claim 10 , in which the OS is to issue a command through a platform communications channel to receive an RAS service.
12. The computing platform of claim 9 , in which the RAS data structure is to be updated at least by a firmware routine initiated from a system interrupt.
13. The computing platform of claim 12 , comprising at least one RAS provider to provide data to update the RAS data structure.
14. The computing platform of claim 12 , in which the firmware routine is to be called by an interrupt routine.
15. The computing platform of claim 9 , in which updatable parts of the RAS structure are to exist in memory that is reserved by the firmware boot program.
16. An apparatus, comprising:
a computer platform having firmware including ACPI components to build a RAS features (RASF) table structure, wherein the RASF table structure comprises a platform RAS capabilities bitmap structure; and wherein the RASF table structure comprises a parameter block structure for memory scrub services.
