From 43bd0bf30fcee4170e137ecd0929053454f7d295 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 14 Apr 2021 13:20:02 +0200 Subject: migration: Move populate_vfio_info() into a separate file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CONFIG_VFIO switch only works in target specific code. Since migration/migration.c is common code, the #ifdef does not have the intended behavior here. Move the related code to a separate file now which gets compiled via specific_ss instead.
