+#
+# qemu -M q35 creates a bare machine with just the very essential
+# chipset devices being present:
+#
+# 00.0 - Host bridge
+# 1f.0 - ISA bridge / LPC
+# 1f.2 - SATA (AHCI) controller
+# 1f.3 - SMBus controller
+#
+# This config file documents the other devices and how they are
+# created. You can simply use "-readconfig $thisfile" to create
+# them all. Here is a overview:
+#
+# 19.0 - Ethernet controller (not created, our e1000 emulation
+# doesn't emulate the ich9 device).
+# 1a.* - USB Controller #2 (ehci + uhci companions)
+# 1b.0 - HD Audio Controller
+# 1c.* - PCI Express Ports
+# 1d.* - USB Controller #1 (ehci + uhci companions,
+# "qemu -M q35 -usb" creates these too)
+# 1e.0 - PCI Bridge
+#
