[Qemu-devel] S3 VGA is deprecated - another graphic card will be emulated. Which one?

[Martin]

Hi all,
I found in lates cvs hw/vga.c "S3 VGA is deprecated - another graphic 
card will be emulated"
and #define CONFIG_S3VGA is commeted out.
I am curious, what card will be emulated?
The good thing about emulating a S3 was that it is one of the three most 
used graphic cards on rs6000 powerpc prep hardware (the ibm GXT110P pci 
graphics card is a S3 card). So emulating this would mean emulating 
quite accurately real prep hardware.
The other cards used on real rs6000 prep hardware are mostly matrox 
based (similar to G200) or IBM proprietary.
So I am curious what the plans are for vga.

Greetings,
Martin

The current target is an SiS PCI VGA card.

Umm, have you got the full spec for one of their chips? is this one of their 
Xabre line or something older?

Also, Do you have any idea about performance gains from emulating this chip 
rather then the VESA graphics that there's today?

Thanks,
Hetz

Something a little older, and most of the specs are available (including 
the ones for 3d).

There will be little performance gain, but it will allow to use a 
standard SiS VGA driver and it will allow hardware 3d emulation in the 
future.
