Graphics driver for Chips and Technologies graphics chipsets

Syntax:

io-graphics -d chips [option[,option...]] ... &

Runs on:

MIPSLE, PowerPC, SHLE, x86, ARMLE

Options:

For the general io-graphics options that can be used with this driver, see io-graphics.

Options specific to this driver:

mode_opts=config_file: Specifies the full path to chips.conf, which is the configuration file for this driver.

Description:

The devg-chips.so driver provides accelerated 2D support for Chips and Technologies graphics chipsets.

You can edit the chips.conf configuration file to enable devg-chips.so to run on your board. For more information on the options available, see the configuration file.

You must specify the location of the configuration file to the devg-chips.so driver via the mode_opts option of io-graphics For example:

io-graphics -d chips xres=640,yres=480, bitpp=16,photon,
mode_opts=/etc/photon/config/chips.conf -pphoton
