Play nice with systems where SEV and SEV-ES are enabled, but all ASIDs
have been carved out for SEV-eS, i.e. where actually running SEV guests
is impossible.
v4:
- Convert all ASID usage to unsigned integers.
- Clean up sev_asid_new() so that it doesn't needlessly overload its
return value.
- Split out the -EBUSY=>-EINVAL change to a separate patch.
v3: https://lore.kernel.org/all/20240104190520.62510-1-Ashish.Kalra@amd.com
Ashish Kalra (1):
KVM: SVM: Add support for allowing zero SEV ASIDs
Sean Christopherson (3):
KVM: SVM: Set sev->asid in sev_asid_new() instead of overloading the
return
KVM: SVM: Use unsigned integers when dealing with ASIDs
KVM: SVM: Return -EINVAL instead of -EBUSY on attempt to re-init
