io-graphics

Photon graphics server subsystem

Syntax:

io-graphics [-c file]
            [-d vid=<vid> did=<did> [, deviceindex=<index>]*]
            [-n name] [-f global|local|none ] [-v] [-e]
            [-w] [-p] [-l] [-h] [-P]

Runs on:

Neutrino

Options:

-c

The configuration file to load. Default is /etc/system/config/display.conf

-d vid=<vid> did=<did> [, deviceindex=<index>]

The driver_options are:

vid=vid

The PCI Vendor ID of the graphics device.

did=did

The PCI Device ID of the graphics device.

deviceindex=index

The device index.

-f

Set the mode of operation for the font service.

The mode can be one of the following values:

global

run the global font server

local

run the local font server

none

connect to an existing font server. This mode is useful if you run a stand-alone font server.

-v

verbose

-e

Do not emit an expose when a photon region is created.

-w

Render library workspace buffer size (default 300K -- in bytes, K or M).

-p

Render layer number of polygon points (default 2048).

-l

Prevent other layers from attaching to a layer used by Photon (lock it).

-n name

Specify the Photon server name. Default is /dev/photon.

-h

For HW Wait Idle calls, only wait for the specified video card (default: wait for all cards in use).

-P

Priority at which to start io-graphics (default: 12).

Description:

The io-graphics command starts a graphics driver.

io-graphics configuration options

The io-graphics utility configuration options are contained within the io-display. Refer to the io-display documentation for more information about io-graphics configuration options.

Files:

The devg-* drivers generally require libffb.so.2 and libdisputil.so.2 at runtime.

Environment variables:

PHFONT_USE_EXTERNAL

If this environment variable exists, io-graphics does not run an internal font server. You should set this environment variable for systems that have remote clients accessing font services on the host machine (e.g. phindows, phditto).
