devg-carmine.so

Graphics driver for Fujitsu Carmine chipsets

Syntax:

io-graphics -d carmine vid=[0x]vendor_id,did=[0x]device_id
            [option[,option...]] ... &

Runs on:

SH, x86

Options:

For the general io-graphics options that you can use with this driver, see io-graphics.

Options specific to this driver:

mode_opts=config-file
The full path to the configuration file for the driver. The sample file is /usr/photon/config/carmine.conf.

Description:

The devg-carmine.so driver provides accelerated 2D and 3D support for the Fujitsu Carmine graphics controller.


Note: This driver is installed with the Advanced Graphics TDK. See the Advanced Graphics TDK documentation for updated information about this driver.

You can edit the configuration file to enable devg-carmine.so to run on your board. Follow the editing instructions in the sample file, /usr/photon/config/carmine.conf, to specify the correct configuration for the required display mode. (For a more detailed explanation of the display settings, see the appropriate Fujitsu documentation.)

If you use a configuration file for this driver, you must use the mode_opts option of io-graphics to specify its location. For example, mode_opts=/usr/photon/config/carmine.conf.

Restrictions:

The carmine.conf file

The carmine.conf file provides additional control over the driver, including dual-head support. This file is also required for providing additional configuration for panel displays. The file (by default located in /usr/photon/config/) contains a description of each option, and several preconfigured command lines for various Carmine device and display combinations.

The Carmine chipset supports two display controllers. In carmine.conf, display-related settings may be specified independently for each display controller.

Additionally, you can use the configuration file to configure:

See the comments in the sample configuration file for more details.

Alpha layer support

The alpha layers work in one of two modes on the Carmine:

The two modes of alpha layer operation are mutually exclusive, and must be selected via the carmine.conf configuration file. The mode of operation can't be changed at runtime. By default, the inline alpha mode is used. To use the other mode, specify this option in the configuration file:

alphamap=1

Files:

This driver needs the following at run time:

libffb.so
Software rasterization library.
