From 8364e1f8379c7f9d3e63f127a585f889906b3e10 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 7 Mar 2018 08:39:17 +0100 Subject: x86/jailhouse: Allow to use PCI_MMCONFIG without ACPI Jailhouse does not use ACPI, but it does support MMCONFIG. Make sure the latter can be built without having to enable ACPI as well. Primarily, its required to make the AMD mmconf-fam10h_64 depend upon MMCONFIG and ACPI, instead of just the former. Saves some bytes in the Jailhouse non-root kernel.
