From aa16508f1d1bce2411fdbe82aa20e559bbd90e48 Mon Sep 17 00:00:00 2001 From: Dongjiu Geng Date: Tue, 12 May 2020 11:06:03 +0800 Subject: ACPI: Build related register address fields via hardware error fw_cfg blob This patch builds error_block_address and read_ack_register fields in hardware errors table , the error_block_address points to Generic Error Status Block(GESB) via bios_linker. The max size for one GESB is 1kb, For more detailed information, please refer to document: docs/specs/acpi_hest_ghes.rst Now we only support one Error source, if necessary, we can extend to support more.
