From 8cc75183b78e91455a03ad3a1a68cd0612f66446 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 14 Jun 2023 13:39:46 -0600 Subject: [PATCH] vfio/pci: Cleanup Kconfig MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It should be possible to select vfio-pci variant drivers without building vfio-pci itself, which implies each variant driver should select vfio-pci-core. Fix the top level vfio Makefile to traverse pci based on vfio-pci-core rather than vfio-pci. Mark MMAP and INTX options depending on vfio-pci-core to cleanup resulting config if core is not enabled. Push all PCI related vfio options to a sub-menu and make descriptions consistent.
