[Qemu-devel] Cirrusvga framebuffer mode?

[Qemu-devel] Cirrusvga framebuffer mode?

[Jean-Michel POURE]

Dear all,

Just a remark: when starting the installation of a Mandrake 10 distro with 
"-pci -cirrusvga" option, the initial graphical boot prompt is disabled. The 
installation goes on in text mode.

The Cirrusvga card may not detected as a framebuffer compatible card.

Cheers,
Jean-Michel

I belive this is a Mandrake 10 installation problem and not QEMU's 
problem, since the Mandrake installation doesn't really check for Cirrus 
Logic stuff probably (no problem with Fedora core 2)

Thanks,
Hetz

Dear Hetz,

During Stage 1, Fedora boots in text mode. Then, Fedora Core 2 switches to 
graphical mode when reaching stage 2. In the case of Fedora, I agree that 
this works for both "-pci" and "-pci -cirrusvga".

On the converse,  SuSE 9.0 and Mandrake 10 are supposed to install in 
graphical mode from stage 1 (probably in framebuffer mode, although I did not 
read the source code of the installers). And graphical mode does not work for 
"-pci -cirrusvga" mode.

Here are some screenshots:

1) Mandrake 10
qemu -cdrom Mandrakelinux10.0-CD1.i586.iso -boot d -m 128 -pci -cirrusvga

qemu -cdrom Mandrakelinux10.0-CD1.i586.iso -boot d -m 128 -pci

2) SuSE 9.1
qemu -cdrom SuSE-9.1-iso.disk1 -boot d -m 128 -pci -cirrusvga

qemu -cdrom SuSE-9.1-iso.disk1 -boot d -m 128 -pci

It seems like Cirrus SVGA framebuffer mode is not detected well.

Kindest regards,
