ACPI, APEI, HEST table parsing
HEST describes error sources in detail; communicating operational parameters (i.e. severity levels, masking bits, and threshold values) to OS as necessary. It also allows the platform to report error sources for which OS would typically not implement support (for example, chipset-specific error registers). HEST information may be needed by other subsystems. For example, HEST PCIE AER error source information describes whether a PCIE root port works in "firmware first" mode, this is needed by general PCIE AER error subsystem. So a public HEST tabling parsing interface is provided. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
