[parisc-linux] framebuffer drivers, sound

[Andi]

Hi,

I tried out the latest kernel and debian packages on my 712/60, and its
running
now for three days without crash, you really made amazing progress
the last few month!

The stifb driver is working for me, but the colors are completely wrong
and the
system crashes if i try to cat /dev/fb0.

I wonder if HP will release specs, we could write framebuffer drivers
that talk
directly to the gfx card, allow mode switching and (is it possible?) set
a linear
mode instead of a planed mode.

The harmony driver does not work for me, if I try to play sound, I get
silence
and then after a few seconds a stange noise, then silence, then strange
noise
and so on.

anyway, keep up the good work!

Yup, the stifb is buggy.  Please, if you have time, it would be great
if you could help clean it up and get it working.  sticon works rather
better but it is still not great.  The STI docs are publically available
from the documentation page.

I hope that I will find the time, but I cant promise anything.

well, sticon has correct colors, but works worse than stifb
(swiching a vt does not redraw the whole screen,
dselect is not usable ...)

Yeah, the STI docs.... HP should release the hardware level
docs, this is the only way to implement a full featured fbdev
driver. A stifb would still be usefull since it is works for
every HP gfxcard with STI BIOS, but a special driver for each
gfxcard would be nice to have things like mode switching.

yeah, but right now we're all too busy working on important things
(eg SMP, glibc, etc) to spend time looking for or sanitising this
documentation.

As long as it gets released eventually -- my guess is X isn't going
to be all that fast on a planar FB where you can only write
one planemask at a time and must use a BIOS call to switch
the planemask. :-)

Hi,

I had hacked up a stifb driver for my 715/64 (Artist GFX card) a few weeks 
ago, which will give you at least correct colors. If you want to test it you 
may download the current (unfinished and ugly!) version from
ftp://people.redhat.com/hdeller/parisc_stifb ,
put both files in /drivers/video/sti and recompile.
This version is based on the XFree86-sources and doesn't fix the cat/dev/fb0 
problem yet.

Greetings,
Helge

it works for me. colors are nice again. Why isnt your patch merged in?

I added
disp->scrollmode = SCROLL_YREDRAW;
at the end of sti_set_disp() in stifb.c

this makes scrolling A LOT faster.

Hi Andreas,

the reasons why I haven't checked it in yet are:
1. currently it's an ugly hack,
2. it's still a hack,
3. it only supports artist gfx's (some 712/xxx and 715/xxx machines) atm,
4. I would like to test it more and clean up the sources before I commit it.

Thanks for the SCROLL_YREDRAW patch. I will upload the updated version to the 
above ftp-site as soon as I have tested it.

Greetings,
Helge

Yes.
Xavier Debacker from the ESIEE Team told me, that this driver worked on his 
715/80.

About mpg123, how did you compile it? When I did it 3 months ago
I had to do some modifications on. I'll be very interested to know how
you did.
 
About saytime, let say it's logical, harmony_audio_poll isn't yet
implemented.
Upgrade of harmony is on the whishlist, and I hope I'll have time to
complete it.

Btw, what are the frequencies of you mp3?
More over, could you test .au files with `cat`?

Thank for your feedback,
Matthieu

they are in the official debian distribution... you can grab them from:

ftp://ftp.debian.org/debian/pool/main/m/mad/
ftp://ftp.de.debian.org/debian/pool/main/s/saydate/
ftp://ftp.de.debian.org/debian/pool/main/s/saytime/

I made no modifications to the program itself, I just tweaked the makefiles
a bit.

I dont know, what frequencies does harmony support?

> More over, could you test .au files with `cat`?

I had the same problem here.
