From c3f66210cf23b1ceda8fe5be8ae4f84fc9948cea Mon Sep 17 00:00:00 2001 From: fuzhongl Date: Tue, 15 Feb 2022 02:43:36 +0800 Subject: [PATCH] Doc: qemu cmdline update for acrn on qemu For platforms which have apicv post-interrupt capability; ACRN would use posted-interrupt to notify another vCPU which in non-root mode; or sync interrupt for itself when it in root-mode.However,QEMU could not handle this properly. So, remove the post-interrupt capability in qemu cmdline.
