Subject: [PATCH 1/2] hw/pci-bridge: pci_expander_bridge fix type in
|
|
pxb_cxl_dev_reset()
|
|
|
|
Reproduce issue with
|
|
|
|
configure --enable-qom-cast-debug ...
|
|
|
|
qemu-system-x86_64 -display none -machine q35,cxl=on -device pxb-cxl,bus=pcie.0

hw/pci-bridge/pci_expander_bridge.c:54:PXB_DEV: Object 0x5570e0b1ada0 is not an instance of type pxb
|
|
Aborted
|
|
|
|
The type conversion results in the right state structure, but PXB_DEV is
|
|
not a parent of PXB_CXL_DEV hence the error. Rather than directly
|
|
cleaning up the inheritance, this is the minimal fix which will be
|
|
followed by the cleanup.
