This patch changes the default choice for cold-plugged bridges from PCIe Native to ACPI Hot-plug with ability to use SHPC and PCIe Native for hot-plugged bridges. This is a list of the PCIe Native hot-plug issues that led to this change: * no racy behavior during boot (see 110c477c2ed) * no delay during deleting - after the actual power off software must wait at least 1 second before indicating about it. This case is quite important for users, it even has its own bug: https://bugzilla.redhat.com/show_bug.cgi?id=1594168 * no timer-based behavior - in addition to the previous example, the attention button has a 5-second waiting period, during which the operation can be canceled with a second press. While this looks fine for manual button control, automation will result in the need to queue or drop events, and the software receiving events in all sort of unspecified combinations of attention/power indicator states, which is racy and uppredictable. * fixes: * https://bugzilla.redhat.com/show_bug.cgi?id=1752465 * https://bugzilla.redhat.com/show_bug.cgi?id=1690256 To return to PCIe Native hot-plug: -global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off Signed-off-by: Julia Suvorova Reviewed-by: Igor Mammedov Reviewed-by: David Gibson --- hw/acpi/ich9.c | 2 +- hw/i386/pc.c | 1 + 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/hw/acpi/ich9.c b/hw/acpi/ich9.c index 2f4eb453ac..778e27b659 100644 --- a/hw/acpi/ich9.c +++ b/hw/acpi/ich9.c @@ -427,7 +427,7 @@ void ich9_pm_add_properties(Object *obj, ICH9LPCPMRegs *pm) pm->disable_s3 = 0;
