|
||||
|
||||
viafb_active_dev:
|
||||
This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
|
||||
DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
|
||||
set viafb_active_dev=DVI. In SAMM case, the previous of
|
||||
viafb_active_dev is primary device, and the following is
|
||||
secondary device.
|
||||
|
||||
For example:
|
||||
To enable one device, such as DVI only, we can use:
|
||||
modprobe viafb viafb_active_dev=DVI
|
||||
To enable two devices, such as CRT+DVI:
|
||||
modprobe viafb viafb_active_dev=CRT+DVI;
|
||||
|
||||
For DuoView case, we can use:
|
||||
modprobe viafb viafb_active_dev=CRT+DVI
|
||||
OR
|
||||
modprobe viafb viafb_active_dev=DVI+CRT...
|
||||
|
||||
For SAMM case:
|
||||
If CRT is primary and DVI is secondary, we should use:
|
||||
modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
|
||||
If DVI is primary and CRT is secondary, we should use:
|
||||
modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
|
||||
|
||||
viafb_display_hardware_layout:
|
||||
This option is used to specify display hardware layout for CX700 chip.
|
||||
1 : LCD only
|
||||
2 : DVI only
|
||||
3 : LCD+DVI (default)
|
||||
4 : LCD1+LCD2 (internal + internal)
|
||||
16: LCD1+ExternalLCD2 (internal + external)
|
||||
|
||||
viafb_second_size:
|
||||
This option is used to set second device memory size(MB) in SAMM case.
|
||||
The minimal size is 16.
|
||||
|
||||
viafb_platform_epia_dvi:
|
||||
This option is used to enable DVI on EPIA - M
|
||||
0 : No DVI on EPIA - M (default)
|
||||
1 : DVI on EPIA - M
|
||||
|
||||
viafb_bus_width:
|
||||
When using 24 - Bit Bus Width Digital Interface,
|
||||
this option should be set.
|
||||
12: 12-Bit LVDS or 12-Bit TMDS (default)
|
||||
24: 24-Bit LVDS or 24-Bit TMDS
|
||||
|
||||
viafb_device_lcd_dualedge:
|
||||
When using Dual Edge Panel, this option should be set.
|
||||
0 : No Dual Edge Panel (default)
|
||||
1 : Dual Edge Panel
|
||||
|
||||
viafb_video_dev:
|
||||
This option is used to specify video output devices(CRT, DVI, LCD) for
|
||||
duoview case.
|
||||
For example:
|
||||
To output video on DVI, we should use:
|
||||
modprobe viafb viafb_video_dev=DVI...
|
||||
|
||||
viafb_lcd_port:
|
||||
This option is used to specify LCD output port,
|
||||
available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
|
||||
for external LCD + external DVI on CX700(External LCD is on DVP0),
|
||||
we should use:
|
||||
modprobe viafb viafb_lcd_port=DVP0...
|
||||
|
||||
Notes:
|
||||
1. CRT may not display properly for DuoView CRT & DVI display at
|
||||
the "640x480" PAL mode with DVI overscan enabled.
|
||||
2. SAMM stands for single adapter multi monitors. It is different from
|
||||
multi-head since SAMM support multi monitor at driver layers, thus fbcon
|
||||
layer doesn't even know about it; SAMM's second screen doesn't have a
|
||||
device node file, thus a user mode application can't access it directly.
|
||||
When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
|
||||
viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
|
||||
3. When console is depending on viafbinfo1, dynamically change resolution
|
||||
and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
|
||||
instead of calling common ioctl function FBIOPUT_VSCREENINFO since
|
||||
viafb doesn't support multi-head well, or it will cause screen crush.
|
||||
4. VX800 2D accelerator hasn't been supported in this driver yet. When
|
||||
using driver on VX800, the driver will disable the acceleration
|
||||
function as default.
|
||||
|
||||
|
||||
[Configure viafb with "fbset" tool]
|
||||
-----------------------------------
|
||||
"fbset" is an inbox utility of Linux.
|
||||
1. Inquire current viafb information, type,
|
||||
# fbset -i
|
||||
|
||||
2. Set various resolutions and viafb_refresh rates,
|
||||
# fbset <resolution-vertical_sync>
|
||||
|
||||
example,
|
||||
# fbset "1024x768-75"
|
||||
or
|
||||
# fbset -g 1024 768 1024 768 32
|
||||
Check the file "/etc/fb.modes" to find display modes available.
|
||||
|
||||
3. Set the color depth,
|
||||
# fbset -depth <value>
|
||||
|
||||
example,
|
||||
# fbset -depth 16
|
||||
|
||||
[Bootup with viafb]:
|
||||
--------------------
|
||||
Add the following line to your grub.conf:
|
||||
append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
