[nwst-dev] New patch with sound and true color support

[Jochen R. <jo...@pa...>]

Hello,

I put up a new patch with support for sound and true color on
the NS1000.

Sound support is enabled by selecting ISA bus support in the General
Setup portion, and the Microsoft Sound System in the OSS sound
modules. The latter will really just select the ad1848 driver. ISA
bus support will enable ISA DMA support, see also
arch/ppc/kernel/prep_pci.c: isa_init_dma(). This driver works compiled
into the kernel. I have not tried it yet as a module, should work
with the proper parameters. I also have not tried recording yet,
should not be a problem, though.

The video driver initializes the card 1024x768 and 8 bits by default.
Using fbset you can run it as 640x480 32bpp, for instance. I still
need to fiddle with the color components for 16 bit color support,
and 800x600 does not work yet at all for some strange reason. With
the 2MB of video memory 1024x768 32bpp will not work.

Colors work ok at 640x480 32bpp in the console, try 'ls --color /dev'
for instance. With fbi I cannot display a true color image properly,
but this should really be a problem of that program. If someone
could verify this with X over framebuffer I would appreciate it. There
is a special howto arround somewhere for this type of setup.

Do an 'apt-get install fbset', then add the following mode setting
to /etc/fb.modes for 640x480 32bpp:

mode "640x480-60-32"
    # D: 25.175 MHz, H: 31.469 kHz, V: 59.94 Hz
    geometry 640 480 640 480 32
    timings 39722 48 16 33 10 96 2
endmode

Now try 'fbset -a 640x480-60-32'...

Patch is here for now:
