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 - MMCONFIG support for x86 guests As most changes affect x86, I would suggest to route the series also via tip after the necessary acks are collected. Changes in v2: - adjusted commit log and include ordering in patch 2 - rebased over Linus master Jan [1] https://lkml.org/lkml/2017/11/27/125 [2] http://jailhouse-project.org CC: Benedikt Spranger <b.spranger@xxxxxxxxxxxxx> CC: Mark Rutland <mark.rutland@xxxxxxx> CC: Otavio Pontes <otavio.pontes@xxxxxxxxx> CC: Rob Herring <robh+dt@xxxxxxxxxx> Jan Kiszka (5): jailhouse: Provide detection for non-x86 systems PCI: Scan all functions when running over Jailhouse x86: Consolidate PCI_MMCONFIG configs x86/jailhouse: Allow to use PCI_MMCONFIG without ACPI MAINTAINERS: Add entry for Jailhouse Otavio Pontes (1): x86/jailhouse: Enable PCI mmconfig access in inmates Documentation/devicetree/bindings/jailhouse.txt | 8 ++++++++ MAINTAINERS | 7 +++++++ arch/x86/Kconfig | 11 ++++++----- arch/x86/include/asm/jailhouse_para.h | 2 +- arch/x86/include/asm/pci_x86.h | 2 ++ arch/x86/kernel/Makefile | 2 +- arch/x86/kernel/cpu/amd.c | 2 +- arch/x86/kernel/jailhouse.c | 7 +++++++ arch/x86/pci/legacy.c | 4 +++- arch/x86/pci/mmconfig-shared.c | 4 ++-- drivers/pci/probe.c | 4 +++- include/linux/hypervisor.h | 17 +++++++++++++++-- 12 files changed, 56 insertions(+), 14 deletions(-) create mode 100644 Documentation/devicetree/bindings/jailhouse.txt -- 2.13.6
