[Qemu-devel] Cirrus VGA

[Qemu-devel] Cirrus VGA

[Fabrice Bellard]

Hi,

The initial version of the Cirrus VGA support is now commited. It is 
currently not enabled as they are some pending issues to solve. gcc 3.x 
is required to compile it as I use the anonymous structure extension of 
gcc to ease the merge.

During the merge, I modified the VGA emulation so that it is easier to 
add new VGA compatible cards.

Fabrice,

just one question: which chip exactly does it emulate? i.e. I still have
crashing issues with Solaris9 X11 on top of emulated VGA, so I would like
to use something better...

Thanks a lot,

Karel

I've checked out a copy from cvs ... and have found FreeBSD 5-CURRENT's
gcc doesn't like the anonymous structure use.

Anyways, I compiled it, tweeked pc.c to use the cirrus driver and
downloaded a CL-GD543x bios from http://www.linuks.mine.nu/ree/video/

So far, looks good... FreeBSD happily changes text modes including the
VESA extended text modes. Haven't tested graphics modes yet.

gcc (GCC) 3.3.3 (Debian 20040422) also doesnt like it...
Maybe it should be taken out of the default build until FreeBSD
and debian get an updated gcc version?

>Anyways, I compiled it,

 Does the lang/gcc33 port work?  or what compiler did you use?

 X would be interesting as with the default vga driver it doesnt work...

 These are fixed in the port btw.

 Huh?  Is the vmware networking module compatible to if_tap somehow?
And is there a description of its features somewhere?

 Curious,

[Qemu-devel] Cirrus VGA

[Fabrice Bellard]

Hi,

The emulated Cirrus PCI VGA adapter CLGD 5446 begins to be usable with 
XFree86/Linux and Windows 98 SE. To make tests, use the CVS and use the 
followings options: "-pci -cirrusvga". You must install the new Cirrus 
specific VGA BIOS before trying.

The depths 8, 15, 16 and 24(at 32 bpp) are supported at any resolution. 
24 bpp is implemented but not tested. ISA mode (GLGD 5430) is 
implemented but has not been tested yet.

Fabrice.

Oops, meant to Cc this to the list...

Yes, X on FreeSBIE now works with -pci -cirrusvga.  Thanx!

 I liked this so much i updated the port again :)  Update can be
fetched at:

 Have fun!
