X-Received-From: 134.134.136.100 Subject: [Qemu-devel] [PATCH v3 8/8] hw: acpi: Remove AcpiRsdpDescriptor and fix tests X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Laurent Vivier , Peter Maydell , Thomas Huth , Eduardo Habkost , Ben Warren , "Michael S. Tsirkin" , Shannon Zhao , qemu-arm@nongnu.org, Igor Mammedov , Paolo Bonzini , Richard Henderson Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" The only remaining AcpiRsdpDescriptor users are the ACPI utils for the BIOS table tests. We remove that dependency and can thus remove the structure itself.
