Re: [RFC PATCH v2 0/4] vfio/pci: Atomic Ops completer support

[Robin Voetter]

Hi Alex,

Thanks for taking the time to implement support for Atomic Op completer
support properly :). I have tested out these patches and the kernel
patch, and apart from a minor issue with patch 2 everything works fine;
ROCm programs that use device->host atomic operations work properly.

Something that I have been thinking about, are there any implications
involved with enabling this feature automatically with no possibility of
turning it off? I have no use case for that, though, and I cant really
think of a reason other than preventing the guest from finding out
hardware details about the host.

Thanks,
