| 34 | * 1. ATIF |
| 35 | * ARG0: (ACPI_INTEGER) function code |
| 36 | * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes |
| 37 | * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes |
| 38 | * ATIF provides an entry point for the gfx driver to interact with the sbios. |
| 39 | * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom |
| 40 | * notification. Which notification is used as indicated by the ATIF Control |
| 41 | * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or |
| 42 | * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS |
| 43 | * to identify pending System BIOS requests and associated parameters. For |
| 44 | * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver |
| 45 | * will perform display device detection and invoke ATIF Control Method |
| 46 | * SELECT_ACTIVE_DISPLAYS. |
| 47 | * |
| 48 | * 2. ATPX |
| 49 | * ARG0: (ACPI_INTEGER) function code |
| 50 | * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes |
| 51 | * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes |
| 52 | * ATPX methods are used on PowerXpress systems to handle mux switching and |
| 53 | * discrete GPU power control. |
| 54 | * |
| 55 | * 3. ATRM |
| 56 | * ARG0: (ACPI_INTEGER) offset of vbios rom data |
| 57 | * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K). |
| 58 | * OUTPUT: (ACPI_BUFFER) output buffer |
| 59 | * ATRM provides an interfacess to access the discrete GPU vbios image on |
| 60 | * PowerXpress systems with multiple GPUs. |
| 61 | * |
| 62 | * 4. ATCS |
| 63 | * ARG0: (ACPI_INTEGER) function code |
| 64 | * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes |
| 65 | * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes |
| 66 | * ATCS provides an interface to AMD chipset specific functionality. |
