Subject: [PATCH] KVM: PPC: Book3S HV: Add H_FAC_UNAVAIL mapping for tracing exits
Date: Fri, 24 Apr 2026 14:55:55 +0530 [thread overview]
Message-ID: <20260424092558.31798-1-Gautam.Menghani@ibm.com> (raw)
From: Gautam Menghani <gautam@linux.ibm.com>
The macro kvm_trace_symbol_exit is used for providing the mappings
for the trap vectors and their names. Add mapping for H_FAC_UNAVAIL so that
trap reason is displayed as string instead of a vector number when using
the kvm_guest_exit tracepoint.
