From fe6603cafabbe9c0213cfaaca24bcbb3cc6e2a51 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Mon, 13 Mar 2023 17:46:11 -0700 Subject: [PATCH] ACPI: APEI: EINJ: Add CXL error types ACPI 6.5 added six new error types for CXL. See chapter 18 table 18.30. Add strings for the new types so that Linux will list them in the /sys/kernel/debug/apei/einj/available_error_types file. It seems no other changes are needed. Linux already accepts the CXL codes (on a BIOS that advertises them). Signed-off-by: Tony Luck Reviewed-by: Davidlohr Bueso Reviewed-by: Dave Jiang Signed-off-by: Rafael J.
