Subject: [PULL 05/36] target/i386: Added ignore TPR check in ctl_has_irq
Date: Mon, 6 Sep 2021 15:10:28 +0200 [thread overview]
Message-ID: <20210906131059.55234-6-pbonzini@redhat.com> (raw)
In-Reply-To: <20210906131059.55234-1-pbonzini@redhat.com>
From: Lara Lazier <laramglazier@gmail.com>
The APM2 states that if V_IGN_TPR is nonzero, the current
virtual interrupt ignores the (virtual) TPR.
