Drop the hard-coded value of 1146 lines which seems to work with HP-UX

active_lines_low and byte 3 of misc_video as it's expected by the Xorg

This potentially allows for higher vertical screen resolutions

I'm adding qemu-devel for extra visibility since you've also measure TCG
performance of x86 and s390x guests in x86/M1 hosts as well.
This is very interesting. Nice work collecting all this data.
As for ppc64 performance I'll say that I am surprised that, in the end,
the ppc64 TCG backend isn't

We have "-sdl" and "-curses", but no "-gtk" and no "-cocoa" ...
these old-style options are rather confusing than helpful nowadays.
Now that the deprecation period is over, let's remove them, so we
get a cleaner interface (where "-display" is the only way to select
the user interface).

These parameters are in the way for further refactoring (since they
use an underscore in the name which is forbidden in QAPI), so let's
remove these now that their deprecation period is over.

The "-display sdl" option still uses a hand-crafted parser for its
parameters since some of them used underscores which is forbidden
in QAPI. Now that they've been deprecated and the deprecation period
is over, we can remove the problematic parameters and switch to use
the QAPI parser instead.

The "-display sdl" option still uses a hand-crafted parser for its
parameters since we didn't want to drag an interface we considered
somewhat flawed into the QAPI schema. Since the flaws are gone now,
it's time to QAPIfy.

Commit 1b7fd729559c ("block: rename buffer_alignment to

At this point, the field is set by the device emulation, but completely
ignored by the block layer.
The last time the value of buffer_alignment/guest_block_size was
actually used was before commit 339064d50639 (
