/* AMD hw uses four ACPI control methods: * 1. ATIF * ARG0: (ACPI_INTEGER) function code * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes * ATIF provides an entry point for the gfx driver to interact with the sbios. * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom * notification. Which notification is used as indicated by the ATIF Control * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS * to identify pending System BIOS requests and associated parameters. For * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver * will perform display device detection and invoke ATIF Control Method * SELECT_ACTIVE_DISPLAYS. * * 2. ATPX * ARG0: (ACPI_INTEGER) function code * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes * ATPX methods are used on PowerXpress systems to handle mux switching and * discrete GPU power control. * * 3. ATRM * ARG0: (ACPI_INTEGER) offset of vbios rom data * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K). * OUTPUT: (ACPI_BUFFER) output buffer * ATRM provides an interfacess to access the discrete GPU vbios image on * PowerXpress systems with multiple GPUs. * * 4. ATCS * ARG0: (ACPI_INTEGER) function code * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes * ATCS provides an interface to AMD chipset specific functionality. *
