Hi All,
Sorry for the [edk2-platforms] prefix attached to the subject line. This is edk2 patch series. Will fix the prefix in next version.
- Omkar.
> Changes since v2:
> - Addressed the comments given by Sami.
> - Added Readme file with all cover letter information.
> - Rebased to the latest upstream code.
>
> Hardware Error Source Table (HEST)[1] and Software Delegated Exception
> Interface (SDEI)[2] ACPI tables are used to acomplish firmware first error
> handling.This patch series introduces a framework to build and install the
> HEST ACPI table dynamically.
>
> The following figure illustrates the possible usage of the dyanamic generation

> All the hardware error sources are added to HEST table as GHESv2[3] error
> source descriptors. The framework comprises of following DXE and MM
> drivers:
>
> - HestTableDxe:
> Builds HEST table header and allows appending error source descriptors to
> the
> HEST table. Also provides protocol interface to install the built HEST table.

> - HestErrorSourceDxe & HestErrorSourceStandaloneMM:
> These two drivers together retrieve all possible error source descriptors of
> type GHESv2 from the MM drivers implementing HEST Error Source
> Descriptor
> protocol. Once all the descriptors are collected HestErrorSourceDxe
> appends
> it to HEST table using HestTableDxe driver.
