Re: [PATCH v5 11/15] coco: host: arm64: Connect RMM pdev streams for IDE devices

[Ankit Agrawal]

Hi Aneesh

As I read it, the address ranges handed to RMM in this patch are captured
once and at the point cca_tsm_connect() runs. That becomes the address
range RMM has on record for the pdev/stream going forward.

So a couple of questions on that..
1.  Is connect -> {driver probe / vfio-pci bind } the intended
     sequence or is that ordering left entirely to userspace/VMM policy?
2. Are the resources/BARs captured at connect time assumed to be
    fixed for the lifetime of the PDEV? If a PCI rescan (or resource
    reassignment such as pci=realloc, a hotplug re-enumeration
    happens after connect, is that expected to be rejected/blocked?

Thanks
