early multihead support

[James S. <jsi...@ac...>]

hi!!

  Well today I have been work on some new code that will allow you to boot
both a MDA display and a VGA con display at the same time. I'm going to
finish it today. Does anyone have a MDA display and a video card that can
run as VGAcon. I really like to give this a try soon. Thank you.

Q: Why did they deprecate a.out support in linux?
A: Because a nasty coff is bad for your elf.

Cool. I just need to talk to Richard Gooch about handling hot swappable
video cards.

What does this mean?

I have such setup, and currently use mdacon and a user space daemon I
wrote to emulate a second terminal with a monochrome monitor and a 2nd
keyboard attahced to the ps/2 mouse port.

Does the console system you write allow this? Does it facilitate having 
multiple terminals?

Really multihead.

Yes and Yes :) Well it will. It needs more work. I need to find away to
create more /dev/ttyX with hot swappable video cards.

OK, so how do I test? I did not find any explanation in the web pages.

Sorry if this reply is too much after the fact, but I have the
required setup you describe above.  I use a PCI Cirrus Logic
with an old ISA mono card with kernels 2.2.x and it works
fine.  If you've got some new code that needs testing, I'd be
glad too.  I also have a Voodoo card in this box as well - if
that makes any difference.

Just let me know if you need any testing, either public testing
or private stuff - you can email me - as can anyone else involved
with the console stuff.

I look forward to this new subsystem.

Take care,
TTYL

I've overclocked my keyboard interface.  It's quite messy dipping my
hands into the mineral oil, but *MAN* is my keyboard ever fast now!

Its almost done. I have to finish the blanking code. After this is
just a matter of changing the size of the VC pools to 16 and with the
current 64 limit we can have 4 active heads at one time. After this I'm
going to have to raise the 64 limit which is going to require alot of tty
code changes :-( I will announce when you will be avaiable for testing and
then once we have it going I will announce it on the kernel and fbdev
mailing list.
