devg-tvia.so

Graphics driver for TVIA CyberPro chipsets

Syntax:

io-display [-vf]
           -d vid=[0x]vendor_id,did=[0x]device_id[,deviceindex=index]
           [-c config_file] [-p priority]

Runs on:

Neutrino

Targets:

MIPSLE, SHLE, x86

Options:

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:

modeopts=config-file
The full path to the configuration file for the driver. For example, tvia.conf is located in /usr/photon/config by default so that the sample file is /usr/photon/config/tvia.conf.

Description:

The devg-tvia.so driver provides accelerated 2D support for TVIA graphics chipset.

On non-x86 systems, install jumper JP3 on the reference adapter.

You can edit the configuration file to enable devg-tvia.so to run on your board. For more information on the options available, see the sample configuration file, /usr/photon/config/tvia.conf.

If you use a configuration file for this driver, you must use the modeopts in your display.conf to specify its location.
