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
115 * ATCS provides an interface to AMD chipset specific functionality.
