For the general io-graphics options that you can use with this driver, see io-graphics.
Options specific to this driver:
The devg-carmine.so driver provides accelerated 2D and 3D support for the Fujitsu Carmine graphics controller.
|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.
|DPMS (power saving)||Yes|

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.
The alpha layers work in one of two modes on the Carmine:
In the GF API, the gf_alpha_t alpha map is configured for blending with an RGB layer as follows:
gf_alpha_t alpha; memset(&alpha, 0, sizeof(alpha)); alpha.mode = GF_ALPHA_M1_MAP | GF_BLEND_SRC_M1 | GF_BLEND_DST_1mM1; alpha.map = asurf; gf_layer_set_blending(fglayer, &alpha);
In the above example, the driver internally picks one of the four alpha layers (if there is still one available) and uses it.
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:
This driver needs the following at run time:
