From 843af0f2e4617db197034b27a9a658a59271f19f Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Fri, 19 Sep 2025 15:32:29 -0700 Subject: [PATCH] KVM: x86/mmu: Pretty print PK, SS, and SGX flags in MMU tracepoints Add PK (Protection Keys), SS (Shadow Stacks), and SGX (Software Guard Extensions) to the set of #PF error flags handled via kvm_mmu_trace_pferr_flags. While KVM doesn't expect PK or SS #PFs in particular, pretty print their names instead of the raw hex value saves the user from having to go spelunking in the SDM to figure out what's going on.
