From 12319ef1cfc7786864107f09f899c0daaac054e3 Mon Sep 17 00:00:00 2001 From: Borislav Petkov (AMD) Date: Wed, 15 Feb 2023 11:01:42 +0100 Subject: virt/coco/sev-guest: Check SEV_SNP attribute at probe time commit d6fd48eff7506bb866a54e40369df8899f2078a9 upstream. No need to check it on every ioctl. And yes, this is a common SEV driver but it does only SNP-specific operations currently. This can be revisited later, when more use cases appear. No functional changes.
