From f28b958cbf08c4019f99091208e5c877b857b030 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Fri, 10 Nov 2023 22:50:35 +0100 Subject: [PATCH] hw/xen: Extract 'xen_igd.h' from 'xen_pt.h' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit "hw/xen/xen_pt.h" requires "hw/xen/xen_native.h" which is target specific. It also declares IGD methods, which are not target specific. Target-agnostic code can use IGD methods. To allow that, extract these methos into a new "hw/xen/xen_igd.h" header.
