| /* 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. |
