> question: Do i need to register our device with this database? > How can i get the acpi string as shown in this patch? A google search for "ACPI id registration" gives this as the first hit: http://www.uefi.org/PNP_ACPI_Registry I believe it has what you want. You did look didn't you? If your device is not a PCI device request an ACPI id from the ACPI Specification Workgroup Chairperson. First check that your vendor does not have an ACPI id already registered. If it is a PCI device you will need a PCI vendor id from the PCI-SIG. To get a PCI vendor id registered with the PCI-SIG you must be a member - that is not free (see https://pcisig.com/membership). If you make a request for an ACPI id I'd strongly recommend that you make the request from a work based email not a gmail account or that the vendor you are working with makes the request instead. I do not know if they will grant a new ACPI id for a company if you cannot show any connection to that company. ��.n��������+%������w��{.n�����{���"�)��jg��������ݢj����G�������j:+v���w�m������w�������h�����٥
