You have a minor conflict wrt upstream due to 7c28b925b7 build: convert pci.mak to Kconfig which adds CONFIG_LSI_SCSI_PCI=y in default-configs/arm-softmmu.mak Thanks Eric > > > RFC --> v2 > > -Use GED device instead of GPIO for ACPI hotplug events. > -Removed NVDIMM support for now. > -Includes dropped patches from Eric's v9 series. > > > Eric Auger (1): > hw/arm/virt: Add memory hotplug framework > > Samuel Ortiz (3): > hw/acpi: Do not create memory hotplug method when handler is not > defined > hw/arm/virt: Add virtual ACPI device > hw/acpi: Add ACPI Generic Event Device Support > > Sebastien Boeuf (1): > hw/acpi: Move constant definitions to header files > > Shameer Kolothum (6): > hw/acpi: Make ACPI IO address space configurable > hw/arm/virt: Add ACPI support for device memory cold-plug > hw/arm/virt-acpi-build: Add PC-DIMM in SRAT > hw/arm/boot: Expose the PC-DIMM nodes in the DT > hw/arm/virt: Add GED device configuration and build aml > hw/arm/virt: Add GED irq routing and Enable memory hotplug > > default-configs/arm-softmmu.mak | 4 + > hw/acpi/Makefile.objs | 1 + > hw/acpi/ged.c | 198 > +++++++++++++++++++++++++++++++++++++++ > hw/acpi/memory_hotplug.c | 58 ++++-------- > hw/arm/Makefile.objs | 2 +- > hw/arm/boot.c | 42 +++++++++ > hw/arm/virt-acpi-build.c | 31 ++++++ > hw/arm/virt-acpi.c | 161 +++++++++++++++++++++++++++++++ > hw/arm/virt.c | 93 +++++++++++++++++- > hw/i386/acpi-build.c | 3 +- > include/hw/acpi/ged.h | 61 ++++++++++++ > include/hw/acpi/memory_hotplug.h | 31 +++++- > include/hw/arm/virt.h | 8 ++ > 13 files changed, 649 insertions(+), 44 deletions(-) > create mode 100644 hw/acpi/ged.c > create mode 100644 hw/arm/virt-acpi.c > create mode 100644 include/hw/acpi/ged.h >
