Framebuffer howto?
Mayuresh Kathe
I am not on the list, and am new to BSD, just graduated from Linux :)
I wanted to port my OS (http://tisya.co.in/) to get away from Linux
completely...
For the same, the only hinderance lies in using framebuffer.
Our GUI is based on Linux framebuffer, we don't use X Win at all...
Is there something similar to Linux FB with FreeBSD?
If yes, how do I activate it?
(on linux there's ad evice at /dev/fb0)
Eagerly awaiting your reply and waiting to take the plunge at full
steam...
Best Regards,
~Mayuresh

I don't think we have a framebuffer, at least not like
Linux. Check out the VESA module and wait for the KGI
port to arrive (not soon but work is going on).
cheers,
Pedro.

Well, since you're writing in hackers@, might I suggest svgalib? If you
don't want to rely on svgalib, there's also libvgl, which comes with
FreeBSD. Example code is in /usr/share/examples/libvgl.
It might not be a framebuffer, but at least svgalib has accelerated
modes, and libvgl just works. Of course you could fall back to X, but
that's even more gross :)
I know that if you use those, it could be considered a gross hack, but
at least you have something to draw with until that KGI stuff is here.
Cheers,
Emiel

can work on top of VGL or Linux's framebuffer, and
when KGI becomes available it will work fine.

Hmm, someone said earlier on in this thread, that FreeBSD does
not have a framebuffer device; if so:
1) What is the FB_INSTALL_CDEV kernel option for?
2) What is the purpose of <sys/fbio.h>?
Clarification will be appreciated.
Cheers.

Well as far as I can see the text console is considered
as kind of a frame buffer. Surely not what quite what
you are looking for.

I understand the Linux framebuffer device was
initially based on our VESA driver, but it has evolved
into a specialized device for specific graphic cards.
It's also a moving target, not something anyone in
FreeBSD has been willing to follow.
There are more important things to do in FreeBSD's
graphics end; fully newbussifying the VESA driver
would be nice, perhaps supporting VBE/AF (like in this
dead project
(http://www.talula.demon.co.uk/freebe/index.html), or
of course helping the KGI porting effort* (Hi Nicholas
;) ).
cheers,
Pedro.
* I understand a VM guru is needed there BTW
