Tsirkin" , Gerd Hoffmann , Igor Mammedov , Paolo Bonzini , Richard Henderson Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" I know that not supporting ACPI in microvm is intentional. If you still don't want ACPI this is perfectly fine, you can use the usual -no-acpi switch to toggle ACPI support. These are the advantages you are going to loose then: (1) virtio-mmio device discovery without command line hacks (tweaking the command line is a problem when not using direct kernel boot). (2) Better IO-APIC support, we can use IRQ lines 16-23. (3) ACPI power button (aka powerdown request) works. (4) machine poweroff (aka S5 state) works. Together with seabios patches for virtio-mmio support this allows to boot standard fedora images (cloud, coreos, workstation live) with the microvm machine type. git branch for testing (including updated seabios): https://git.kraxel.org/cgit/qemu/log/?h=sirius/microvm changes in v2: * some acpi cleanups are an separate patch series now. * switched to hw reduced acpi & generic event device. * misc fixes here and there. cheers, Gerd Gerd Hoffmann (13): acpi: make build_madt() more generic. acpi: create acpi-common.c and move madt code acpi: madt: skip pci override on pci-less systems (microvm) acpi: move acpi_build_facs to acpi-common.c acpi: move acpi_init_common_fadt_data to acpi-common.c acpi: move acpi_align_size to acpi-common.h acpi: fadt: add hw-reduced sleep register support acpi: generic event device for x86 microvm: add minimal acpi support microvm: disable virtio-mmio cmdline hack microvm: add acpi_dsdt_add_virtio() for x86 microvm: make virtio irq base runtime configurable microvm/acpi: use GSI 16-23 for virtio hw/i386/acpi-common.h | 38 ++++ hw/i386/acpi-microvm.h | 6 + include/hw/acpi/acpi-defs.h | 2 + include/hw/acpi/generic_event_device.h | 10 + include/hw/i386/microvm.h | 10 +- hw/acpi/aml-build.c | 4 +- hw/i386/acpi-build.c | 198 +------------------- hw/i386/acpi-common.c | 206 ++++++++++++++++++++ hw/i386/acpi-microvm.c | 249 +++++++++++++++++++++++++ hw/i386/generic_event_device_x86.c | 114 +++++++++++ hw/i386/microvm.c | 36 +++- hw/i386/Kconfig | 1 + hw/i386/Makefile.objs | 3 + 13 files changed, 676 insertions(+), 201 deletions(-) create mode 100644 hw/i386/acpi-common.h create mode 100644 hw/i386/acpi-microvm.h create mode 100644 hw/i386/acpi-common.c create mode 100644 hw/i386/acpi-microvm.c create mode 100644 hw/i386/generic_event_device_x86.c
