How to configure ACPI files (for multiple sensors sharing a hid spi)?

How can I write an ACPI file when multiple sensors use one his spi?

  1. Write an .asl file for each sensor
  2. Write an .asl file to include all sensors (I'm not sure if this method is feasible, could anyone help provide an example as a reference)?

    Hello there,

    This article might help you out in getting some sample codes https://github.com/Microsoft/Windows-driver-samples/blob/main/usb/UcmCxUcsi/Acpi.cpp

    For each device described in the ACPI namespace hierarchy, the Windows ACPI driver, Acpi.sys, creates either a filter device object (filter DO) or a physical device object (PDO). If the device is integrated into the system board, Acpi.sys creates a filter device object, representing an ACPI bus filter, and attaches it to the device stack immediately above the bus driver (PDO). https://learn.microsoft.com/en-us/windows-hardware/drivers/kernel/acpi-driver

    Hope this resolves your Query !!
