Subject: [PATCH 2/2] KVM: x86: Remove VT-d mention in posted interrupt tracepoint
Date: Wed, 17 Apr 2024 20:08:49 +0000	[thread overview]
Message-ID: <20240417200849.971433-3-alejandro.j.jimenez@oracle.com> (raw)
In-Reply-To: <20240417200849.971433-1-alejandro.j.jimenez@oracle.com>

The kvm_pi_irte_update tracepoint is called from both SVM and VMX vendor
code, and while the "posted interrupt" naming is also adopted by SVM in
several places, VT-d specifically refers to Intel's "Virtualization
Technology for Directed I/O".
