From 8b3d26342c4aa171e759e6392fe3b742759d4963 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Fri, 25 Aug 2017 16:54:06 -0300 Subject: [PATCH] xio3130_downstream: Report error if pcie_chassis_add_slot() failed On commit f8cd1b02 ("pci: Convert to realize"), no error_set*() call was added for the pcie_chassis_add_slot() error case. pcie_chassis_add_slot() errors get ignored, making QEMU crash later. e.g.: $ qemu-system-x86_64 -device ioh3420 -device xio3130-downstream qemu-system-x86_64: memory.c:2166: memory_region_del_subregion: Assertion `subregion->container == mr' failed. Aborted (core dumped) Fix it by reporting the error using error_setg().
