From 75d5f34396c7f951f99a8c9800db29b4a98c8f67 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 23 Jun 2023 14:45:50 +0200 Subject: [PATCH] hw/i386/acpi-build: Rely on machine->device_memory when building SRAT MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We're already looking at machine->device_memory when calling build_srat_memory(), so let's simply avoid going via PC_MACHINE_DEVMEM_REGION_SIZE to get the size and rely on machine->device_memory directly. Once machine->device_memory is set, we know that the size > 0. The code now looks much more similar the hw/arm/virt-acpi-build.c variant.
