Hi,
I am using 2.6.10 but my davincifb.c looks a bit different here is the display
function I have, notice it uses d->mode and d->interface instead of
dmparams.output and dmparams.format, I tried replacing 'output' and 'format'
with 'mode' and 'interface' in my bootargs but still no change at the output.
void init_display_function(struct vpbe_display_format *d)
{
if (d->mode == NON_EXISTING_MODE)
dm->output_device_config = vpbe_davincifb_dlcd_nonstd_config;
else if ((d->mode == NTSC) && (d->interface == COMPOSITE))
dm->output_device_config = davincifb_ntsc_composite_config;
else if ((d->mode == NTSC) && (d->interface == SVIDEO))
dm->output_device_config = davincifb_ntsc_svideo_config;
else if ((d->mode == NTSC) && (d->interface == COMPONENT))
dm->output_device_config = davincifb_ntsc_component_config;
else if ((d->mode == PAL) && (d->interface == COMPOSITE))
dm->output_device_config = davincifb_pal_composite_config;
else if ((d->mode == PAL) && (d->interface == SVIDEO))
dm->output_device_config = davincifb_pal_svideo_config;
else if ((d->mode == PAL) && (d->interface == COMPONENT))
dm->output_device_config = davincifb_pal_component_config;
else if ((d->mode == NTSC) && (d->interface == RGB))
dm->output_device_config = vpbe_davincifb_ntsc_rgb_config;
else if ((d->mode == PAL) && (d->interface == RGB))
dm->output_device_config = vpbe_davincifb_pal_rgb_config;
else if ((d->mode == P525) && (d->interface == COMPONENT))
dm->output_device_config = vpbe_davincifb_525p_component_config;
else if ((d->mode == P625) && (d->interface == COMPONENT))
dm->output_device_config = vpbe_davincifb_625p_component_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == YCC16))
dm->output_device_config = vpbe_davincifb_default_ycc16_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == YCC8))
dm->output_device_config = vpbe_davincifb_default_ycc8_config;
else if ((d->mode == P480) && (d->interface == PRGB))
dm->output_device_config = vpbe_davincifb_480p_prgb_config;
else if ((d->mode == P400) && (d->interface == PRGB))
dm->output_device_config = vpbe_davincifb_400p_prgb_config;
else if ((d->mode == P350) && (d->interface == PRGB))
dm->output_device_config = vpbe_davincifb_350p_prgb_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == SRGB))
dm->output_device_config = vpbe_davincifb_default_srgb_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == EPSON))
dm->output_device_config = vpbe_davincifb_default_epson_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == CASIO1G))
dm->output_device_config = vpbe_davincifb_default_casio_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == UDISP))
dm->output_device_config = vpbe_davincifb_default_UDISP_config;
else if ((d->mode == DEFAULT_MODE) && (d->interface == STN))
dm->output_device_config = vpbe_davincifb_default_STN_config;
/* Add support for other displays here */
else {
dev_err(dm->dev, "Unsupported output device!\n");
dm->output_device_config = NULL;
}
}
Also, when I boot I only see the "Kernel Command Line:..." containing my
bootargs, I do not see any line along the lines of "DaVinci: Output on NTSC in
RGB format". I have attached the output of 'dmesg'.
Thanks,
Euan

Oh? What version of the kernel are you using? I was looking at both
mvista 2.6.10 and git and saw these:
if ((dmparams.output == NTSC) && (dmparams.format == COMPOSITE))
dm->output_device_config = davincifb_ntsc_composite_config;
else if ((dmparams.output == NTSC) && (dmparams.format == SVIDEO))
dm->output_device_config = davincifb_ntsc_svideo_config;
else if ((dmparams.output == NTSC) && (dmparams.format == COMPONENT))
dm->output_device_config = davincifb_ntsc_component_config;
else if ((dmparams.output == PAL) && (dmparams.format == COMPOSITE))
dm->output_device_config = davincifb_pal_composite_config;
else if ((dmparams.output == PAL) && (dmparams.format == SVIDEO))
dm->output_device_config = davincifb_pal_svideo_config;
else if ((dmparams.output == PAL) && (dmparams.format == COMPONENT))
dm->output_device_config = davincifb_pal_component_config;
FWIW, technically, NTSC and PAL RGB modes just don't make sense - at
least not to me, as NTSC/PAL are Y/C-based. However in this case they're
just used as names to identify the config, so use whatever you want :)

At least two places visible when the kernel boots up, and also in the
output of dmesg. One looks like:
Kernel command line: mem=120M console=ttyS0,115200n8 root=/dev/hda1
rw noinitrd ip=dhcp video=dm64xxfb:output=pal
and the other I described earlier:
DaVinci: Output on NTSC in RGB format ...
> Is it possible to

SPRAAN0 that I posted earlier describes some patches for run-time
switching of the display parameters.
Cheers,
Bernard.
