S3C64XX(4)

NAME
s3c64xx - video driver for the Samsung s3c64xx framebuffer device

SYNOPSIS

DESCRIPTION
s3c64xx is an Xorg driver for framebuffer devices. This is a non-accelerated driver, the following framebuffer depths are supported: 8, 15, 16, 24. All visual types are supported for depth 8, and TrueColor visual is supported for the other depths. Multi-head configurations are supported.

SUPPORTED HARDWARE
The s3c64xx driver supports all hardware where a framebuffer driver is available. s3c64xx uses the os-specific submodule fbdevhw(4) to talk to the kernel device driver. Currently a fbdevhw module is available for linux.

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

For this driver it is not required to specify modes in the screen section of the config file. The s3c64xx driver can pick up the currently used video mode from the framebuffer driver and will use it if there are no video modes configured.

For PCI boards you might have to add a BusID line to the Device section. See above for a sample line. You can use " -scanpci" to figure out the correct values.

The following driver Options are supported:

Option "s3c64xx" "string"
    The framebuffer device to use. Default: /dev/fb0.

Option "ShadowFB" "boolean"
    Enable or disable use of the shadow framebuffer layer. Default: on.

Option "Rotate" "string"
    Enable rotation of the display. The supported values are "CW" (clockwise, 90 degrees), "UD" (upside down, 180 degrees) and "CCW" (counter clockwise, 270 degrees). Implies use of the shadow framebuffer layer. Default: off.
