From 1ad2e774f4fd3f720d5db07e86fe60df13f21a6d Mon Sep 17 00:00:00 2001 From: Heyi Guo Date: Mon, 9 Dec 2019 14:37:19 +0800 Subject: [PATCH] hw/arm/acpi: enable SHPC native hot plug After the introduction of generic PCIe root port and PCIe-PCI bridge, we will also have SHPC controller on ARM, so just enable SHPC native hot plug. Also update tests/data/acpi/virt/DSDT* to pass "make check". Cc: Shannon Zhao Cc: Peter Maydell Cc: "Michael S. Tsirkin" Cc: Igor Mammedov Reviewed-by: Michael S.
