From 36cdc8b3b87b8a42933b1987ad00cbe1c1a6f6d8 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 25 Nov 2022 11:52:38 +0000 Subject: [PATCH] hw/intc/xics: Reset TYPE_ICS objects with device_cold_reset() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The realize method for the TYPE_ICS class uses qemu_register_reset() to register a reset handler, as a workaround for the fact that currently objects which directly inherit from TYPE_DEVICE don't get automatically reset. However, the reset function directly calls ics_reset(), which is the function that implements the legacy reset method. This means that only the parent class's data gets reset, and a subclass which also needs to handle reset, like TYPE_PHB3_MSI, has to register its own reset function. Make the TYPE_ICS reset function call device_cold_reset() instead: this will handle reset for both the parent class and the subclass, and will work whether the classes are using legacy reset or 3-phase reset. This allows us to remove the reset function that the subclass currently has to set up.
