Subject: [Qemu-devel] VGA cirrus patch prevents video output
Date: Thu, 5 Jul 2018 22:41:43 -0400 [thread overview]
Message-ID: <6E19EBEF-B31C-473C-8279-49A28D571F61@gmail.com> (raw)
I noticed that the video in QEMU stopped working. When I start qemu-system-ppc all I see is a black window. Not even OpenBIOS displays anything. After some bisecting I found out it was this patch that causes the problem:

ppc: Include vga cirrus card into the compiling process
Drivers for this card exists on PPC-based AmigaOS guests so it is useful to
allow users to emulate the graphics card for PPC machines.
As cirrus vga is currently preferred over std(vga) in absence of any user
choice, this change also sets the default display of spapr machines to
std as otherwise qemu refuses to start these machines. Not specifying an
explicit graphics mode is for instance done by 'make check'.

I think a solution to this problem might be to have the mac99 machine use "-vga std" as default. When I use -vga std, video works again.
