From f6b3c72c23661e5534cd2eede16e9bac7ebb761c Mon Sep 17 00:00:00 2001 From: Feng Wu Date: Tue, 19 May 2015 17:07:16 +0800 Subject: x86/irq: Define a global vector for VT-d Posted-Interrupts Currently, we use a global vector as the Posted-Interrupts Notification Event for all the vCPUs in the system. We need to introduce another global vector for VT-d Posted-Interrtups, which will be used to wakeup the sleep vCPU when an external interrupt from a direct-assigned device happens for that vCPU.
