From d644e5e44ff627d6b4da73a65795f60335ba4cb9 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Wed, 11 May 2022 20:15:28 +0530 Subject: [PATCH] hw/riscv: virt: Fix interrupt parent for dynamic platform devices When both APLIC and IMSIC are present in virt machine, the APLIC should be used as parent interrupt controller for dynamic platform devices. In case of multiple sockets, we should prefer interrupt controller of socket0 for dynamic platform devices.
