Mmm. I guess the wiki page is just wrong, then. I have some prototype patches
that work, but I need to check somehow what the real hardware's response to
various edge cases is:
* trying to set a virtual screen size that's smaller than the physical screen
size
* trying to set the virtual x/y of
The virtual size must be at least the size of the physical display. One
approach toward double-buffering is to make the virtual height twice the
physical height. To "flip" the displays you simply change the start of
the visible view port.

Thanks for the test case. I'm having difficulty matching up your guest
code with the documentation of the fb mbox tags in
https://github.com/raspberrypi/firmware/wiki/Mailbox-property-interface
...
Your code sets the physical height to FBHEIGHT via tag 0x48003, and the
virtual height to FBHEIGHT *
Whoops.. Forgot to include the QEMU command line:
qemu-system-aarch64 -M raspi3 --kernel kernel8.img -serial stdio

Certainly! Attached.
If you start the attached on a piece of hardware, it will start and display
fine.. If you start it in QEMU, it will start but display a double-height
screen rather than limiting the physical screen to the specified dimensions.
(The virtual display is double-height in prep
Can you provide a test binary and QEMU command line that reproduce this,
please ?
