Introduce the basic VMI sub-arch configuration dependencies. VMI kernels only are designed to run on modern hardware platforms. As such, they require a working APIC, and do not support some legacy functionality, including APM BIOS, ISA and MCA bus systems, PCI BIOS interfaces, or PnP BIOS (by implication of dropping ISA support). They also require a P6 series CPU. Signed-off-by: Zachary Amsden

Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest is currently pending in the tip tree. This builds on top and enhances the PCI support for x86 and also ARM guests (ARM[64] does not require platform patches and works already). Key elements of this series are: - detection of Jailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected -

From: Jan Kiszka <jan.kiszka at siemens.com> Since e279b6c1d329 ("x86: start unification of arch/x86/Kconfig.*"), we have two PCI_MMCONFIG entries, one from the original i386 and another from x86_64. This consolidates both entries into a single one. The logic for x86_32, where this option was not under user control, remains identical. On x86_64, PCI_MMCONFIG becomes additionally

From: Jan Kiszka <jan.kiszka at siemens.com> 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, we need 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.
