Number 40 is skipped and I was told internally the reason is mentioned
in cover letter
Note that AMD has taken 40 for KVM_EXIT_SNP_REQ_CERTS in the
patch [4] under review, to avoid conflict, use number 41 for
KVM_EXIT_TDX_GET_QUOTE and number 42 for
KVM_EXIT_TDX_SETUP_EVENT_NOTIFY.
I think we shouldn't give up number 40 unless this series depends on AMD
one or it's agreement that AMD one will be queued/merged earlier.
Yes, if this patch needed to sit in kvm-coco-queue with AMD patches for awhile
it might make sense. But it sounds like the plan is to include it in base
support.
Right, now it seems that this patch could probably win the race upstream,
will use number 40 for KVM_EXIT_TDX_GET_QUOTE in the next version if no
objections.
