Hi Liviu,
Sorry for the trouble.
I got why 'res->parent' is not set in my case.
Basically my SR-IOV device has fixed resources, so resources will not
be allocated/assigned and hence parent resource is not set.
I will move the resource claiming to host controller driver as a fixup
so that parent re

I assume you have checked that there is indeed
Hi Liviu,
Issue may not be only with SR-IOV resources.
I am not an expert with Linux PCI core. But i am trying to understand
how even for a non SR-IOV capable device's resource, gets a parent
associated with it.
When a PCI device driver calls pci_enable_device() which inturn calls
'arch/arm64/ke

Hi Liviu,
I am using your ARM64 PCIe patches to write a PCIe host controller
driver for our SOC. I am facing an issue with SR-IOV capable device.
Consider an PCI Express endpoint connected to a PCI Express
Root Port. The PCI Express endpoint provides PCI-SIG SR-IOV
capabilities with a single phy
