/* 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.
