ATIF 37 * ARG0: (ACPI_INTEGER) function code 38 * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes 39 * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes 40 * ATIF provides an entry point for the gfx driver to interact with the sbios. 41 * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom 42 * notification. Which notification is used as indicated by the ATIF Control 43 * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or 44 * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS 45 * to identify pending System BIOS requests and associated parameters. For 46 * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver 47 * will perform display device detection and invoke ATIF Control Method 48 * SELECT_ACTIVE_DISPLAYS. 49 * 50 * 2. ATPX 51 * ARG0: (ACPI_INTEGER) function code 52 * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes 53 * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes 54 * ATPX methods are used on PowerXpress systems to handle mux switching and 55 * discrete GPU power control. 56 * 57 * 3. ATRM 58 * ARG0: (ACPI_INTEGER) offset of vbios rom data 59 * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K). 60 * OUTPUT: (ACPI_BUFFER) output buffer 61 * ATRM provides an interfacess to access the discrete GPU vbios image on 62 * PowerXpress systems with multiple GPUs. 63 * 64 * 4. ATCS 65 * ARG0: (ACPI_INTEGER) function code 66 * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes 67 * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes 68 * ATCS provides an interface to AMD chipset specific functionality. 69 * 70 */ 71 /* ATIF */ 72 #define ATIF_FUNCTION_VERIFY_INTERFACE 0x0 73 /* ARG0: ATIF_FUNCTION_VERIFY_INTERFACE 74 * ARG1: none 75 * OUTPUT: 76 * WORD -
