Graphics driver for Fujitsu Carmine chipsets
io-display [-vf] -d vid=[0x]vendor_id,did=[0x]device_id[,deviceindex=index] [-c config_file] [-p priority]
SHLE, x86, PowerPC
For the general io-display options that you can use with this driver, see io-display.
You can set configuration options that are specific to this driver by using the modeopts setting in display.conf:
The devg-carmine.so driver provides accelerated 2D and 3D support for the Fujitsu Carmine graphics controller.
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 modeopts setting in your display.conf configuration file to specify its location.
|Graphics drivers run at a higher priority than applications, but they shouldn't run at a higher priority than the audio, or else breaks in the audio occur. You can use the on command to adjust the priorities of the audio and graphics drivers.|
|DPMS (power saving)||Yes|
|Display size (pixels):||Refresh rate (Hz):||Color depth (bits per pixel):|
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:
