dm: acpi_dev: Support more ACPI device pass through
In current implementation, --acpidev_pt parameter is a wrapper of MMIO device pass through, which only support TPM pass through with MMIO region. This patch extends --acpidev_pt to a fully functional parameter to support more ACPI device with multi resource, such as MMIO resource, PIO resource and IRQ resource. Device model will parse attributes of different type of resources and invoke corresponding hypercall to assign resource in hypervisor. Here is example of new --acpidev_pt command: --acpidev_pt PNP0501,uid=19,type=irq,irq=5 --acpidev_pt PNP0501,uid=19,type=io_port,min=0x258,len=8 --acpidev_pt INTC1055,uid=0,type=irq,irq=14,polarity=3,trigger_mode=3 --acpidev_pt INTC1055,uid=0,type=memory,min=0xfd6e0000,len=0x10000 The new added target device of ACPI device pass through function is legacy UART and GPIO controller. Before launching VMs, launch script should handle these device to avoid Service VM from access their resource. Driver of both legacy UART and GPIO controller provide unbind interface to unbind device instance from Service VM. This patch also refine TPM pass through to align with new ACPI device pass through framework. For TPM, tpm_tis driver also provide unbind interface to unbind TPM device instance from Service VM. All these unbinding operation should be executed by launch script before acrn-dm command.
