/* 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.

	82	/* AMD hw uses four ACPI control methods:
	83	* 1. ATIF
	84	* ARG0: (ACPI_INTEGER) function code
	85	* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
	86	* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
	87	* ATIF provides an entry point for the gfx driver to interact with the sbios.
	88	* The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
	89	* notification. Which notification is used as indicated by the ATIF Control
	90	* Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
	91	* a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
	92	* to identify pending System BIOS requests and associated parameters. For
	93	* example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
	94	* will perform display device detection and invoke ATIF Control Method
	95	* SELECT_ACTIVE_DISPLAYS.
	96	*
	97	* 2. ATPX
	98	* ARG0: (ACPI_INTEGER) function code
	99	* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
	100	* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
	101	* ATPX methods are used on PowerXpress systems to handle mux switching and
	102	* discrete GPU power control.
	103	*
	104	* 3. ATRM
	105	* ARG0: (ACPI_INTEGER) offset of vbios rom data
	106	* ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
	107	* OUTPUT: (ACPI_BUFFER) output buffer
	108	* ATRM provides an interfacess to access the discrete GPU vbios image on
	109	* PowerXpress systems with multiple GPUs.
	110	*
	111	* 4. ATCS
	112	* ARG0: (ACPI_INTEGER) function code
	113	* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
	114	* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
