General description

CHARON-AXP supports emulation of PBXGA graphics card by direct virtualization. CHARON provides a virtual console for displaying graphics. The console starts automatically upon starting CHARON. Its resolution is 800 x 600 by default .

Important notes

  • PBXGA graphics console cannot be used as the system console. Use OPA0 for this purpose.
  • If PBXGA graphics card is going to be used the resolution of CHARON host screen must be sufficient to provide ability to display the graphics console properly.
  • If PBXGA graphics card is used CHARON cannot run as a service so not compatible with the Linux Toolkit. It can however work in detached mode.
  • If the window of the PBXGA graphics card console is closed by user (or killed as a process) it will not re-appear automatically (CHARON will continue to work in this case). In this situation user has to restart the pbxga_tv program with the correct parameters, as defined in the configuration file, to restart the graphical display.

Configuration parameters

size

Parametersize
TypeText string
Value

Predefine the graphic screen size.

Possible values: 640x480, 800x600 (default), 1024x768, 1152x900, 1280x1024, 1920x1080

Example:

set GYA size = 1024x768

cpu_draw

Parametercpu_draw
Typeboolean
Value

Offloading raster operations. The default value is "true"

Example:

set GYA cpu_draw = false

application

Parameterapplication
TypeText string
Value

Specifies the application to open for displaying the graphical console.

The pbxga_tv executable file is provided for this. It is located in the same folder as the Charon emulator executable file.

Syntax:

pbxga_tv -c <configuration_name> -n <device name(s)>

(info) When several graphic cards are loaded, the <device name(s)> have to be separated by a pipe character and the application has to be defined for the latest loaded PBXGA card. See examples further.

Example:

set GYA application = "pbxga_tv -c DS20 -n GYA"

Examples

Example 1: 8-bpp graphics on AlphaServer 400

...
set session hw_model = AlphaServer_400
set session configuration_name = AS400
...
load PBXGA_AA GYA irq_bus = isa size = 1024x768
set GYA application = "pbxga_tv -c AS400 -n GYA"

Example 2: 24-bpp graphics on AlphaServer DS20

...

set session hw_model = AlphaServer_DS20
set session configuration_name = DS20
...
load PBXGA_BA GYA size = 1280x1024
set GYA application = "pbxga_tv -c DS20 -n GYA"

Example 3: dual head display, 2x1280x10242x 1280x1024

...

set session hw_model = AlphaServer_ES45
set session configuration_name = ES45
...
load PBXGA_BA GYA size = 1280x1024
load PBXGA_BA GYB size = 1280x1024
set GYB application = "pbxga_tv -c ES45 -n GYA|GYB"

Example 4: triple head display, 3x1280x10243x 1280x1024

...
set session hw_model = AlphaServer_ES45
set session configuration_name = ES45
...
load PBXGA_BA GYA size = 1280x1024
load PBXGA_BA GYB size = 1280x1024
load PBXGA_BA GYC size = 1280x1024
set GYC application = "pbxga_tv -c ES45 -n GYA|GYB|GYC"
