[Qemu-devel] [PATCH 05/14] tests: acpi: fetch X_DSDT if pointer to DSDT


From: Igor Mammedov
Subject: [Qemu-devel] [PATCH 05/14] tests: acpi: fetch X_DSDT if pointer to DSDT is 0
Date: Tue, 15 Jan 2019 16:40:57 +0100

that way it would be possible to test a DSDT pointed by
64bit X_DSDT field in FADT.

PS:
it will allow to enable testing arm/virt board, which sets
only newer X_DSDT field.
