DESCRIPTION

amd is an Xorg driver for Advanced Micro Devicess GEODE processor family. It uses the CIMARRON kit provided by Advanced Micro Devices. The driver is accelerated, and provides support for the following framebuffer depths: 8, 16 and 24.

SUPPORTED HARDWARE

The amd driver supports GeodeLX (5536 companion chip).

CONFIGURATION DETAILS

Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver.

The driver will auto-detect the amount of video memory present. If actual the amount of active video memory should be changed, this may be specified with a VideoRam entry in the config file. The driver will attempt to allocate all public/free reigons from the framebuffer memory, as allocated by the kernel cimarron module. All private framebuffer reservations should be made before starting X. Note that X attempts to open /dev/video# devices during initialization, so that attached drivers may allocate framebuffer memory before X reserves it. X will try to reserve framebuffer memory using "/dev/cim" (char device node 10,156).

"Device" section.

The following driver Options are supported:

Option "HWCursor"
Option "SWCursor"
Enable HW or SW cursor.
Default: HW cursor.
Option "Accel"
Option "NoAccel"
Disable or enable acceleration.
Default: acceleration enabled.
Option "Compression"
Option "NoCompression"
Disable or enable compression.
Default: compression is enabled.
Option "ShadowFB"
Option "NoShadowFB"
Enable or disable use of the shadow framebuffer layer.
Default: off.
Option "Rotate" "CW"
Option "Rotate" "Invert"
Option "Rotate" "CCW"
The display may be "rotated" in 3 ways, ClockWise, Upside-Down and CounterClocwise using: This is accomplished using a "shadow" framebuffer, and using either a hardware or software operation to transform the image to the operational display buffer.
Default: no rotation.
Option "FPDestGeom" "WxH"
This allows the configuration to override the bios probe of the FlatPanel output interface. Since flat-panels have fixed timing - that is, only one "real" mode - the mode switch operation which normally might select a wide variety of operational states must scale the mode selection to fit the fixed panel timing. This option is used to communicate that the mode selection is for a flat panel. When this option is used, the bios probe is skipped and the specified geometry is used to derive timings.
Default: bios.
Option "FPActiveGeom" "WxH"
This allows the configuration of the active flatpanel display area. This area must fit into the destination geometry area. The source (mode WxH) geometry will be scaled to the active geometry, and centered in the destination geometry of the FlatPanel output.
Default: FPDestGeom.
Option "FlatPanel"
Option "NoFlatPanel"
This allows the configuration to override the initialization probe to enable or disable the FlatPanel output interface.
Default: bios.
Option "CrtEnable"
Option "NoCrtEnable"
This allows the configuration to override the initialization probe to enable or disable the CRT output interface.
Default: bios.
Option "OSMImageBuffers" "integer"
This sets the number of scanline buffers to be allocated in offscreen scanline memory for acceleration. This can take any value 0 will disable the allocation. Disabled if cannot allocate requested scanline memory.
Default: 20.
Option "OSMColorExpBuffers" "integer"
This sets the number of scanline buffers to be allocated in offscreen color expansiopn memory for acceleration. This can take any value 0 will disable the allocation. Disabled if cannot allocate requested scanline memory.
Default: 20.

DESCRIPTION

amd is an Xorg driver for Advanced Micro Devices GEODE processor family. It uses the DURANGO kit provided by Advanced Micro Devices. The driver is accelerated, and provides support for the following framebuffer depths: 8, 16 and 24.

SUPPORTED HARDWARE

The amd driver supports GXLV (5530 companion chip), SC1200, SC1400 and GX (5535 companion chip).

CONFIGURATION DETAILS

Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver.

The driver will auto-detect the amount of video memory present for all chips. If the amount of memory is detected incorrectly, the actual amount of video memory should be specified with a VideoRam entry in the config file "Device" section.

The following driver Options are supported:

Option "SWCursor" "boolean"
Enable or disable the SW cursor. Default: off.
Option "HWCursor" "boolean"
Enable or disable the HW cursor. Default: on.

Option "Rotate" "CCW"
Rotate the display counterclockwise. This mode is unaccelerated, and uses the Shadow Frame Buffer layer. Default: no rotation.
Option "FlatPanel" "boolean"
This enables the FlatPanel display unit. The FlatPanel depends on the BIOS to do the Pnale h/w initialization. In GX based platforms with TFT part Flatpanel is enabled, and on CRT part is disabled. Default: off.
