From 65fc04ff3cf5b91c0490c80714f97ae6a43d7ee8 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 29 Apr 2022 15:41:02 +0100 Subject: [PATCH] qtests/bios-tables-test: Add a test for CXL emulation. The DSDT includes several CXL specific elements and the CEDT table is only present if we enable CXL. The test exercises all current functionality with several CFMWS, CHBS structures in CEDT and ACPI0016/ACPI00017 and _OSC entries in DSDT.
