Re: [Xen-devel] [PATCH 4/7] arm: smccc: handle SMCs according to SMCCC

Hi Volodymyr,

We can stick to XEN-only approach, like XENFEAT_* or "xen,smccc" in DT.
But is this right?

Answering to this question after some thoughts and discussion around.

The generic approach is indeed the best solution, however I am afraid it will take some times to get ready and might not be ready for Xen 4.10.

As I mentioned earlier, I don't want to merge this without any way to discover the existence of SMCCC in the hypervisor. I also understand that you would like to get this merged in Xen 4.10.

So the alternative we have is to provide a XEN-only approach for the time being. It has to work for both ACPI and DT, this likely means we want a XENFEAT_* flag.

That alternative would be supersede when the generic approach will be available. Though we would have to keep both around, but it is it not a big deal.

Does it make sense?
