I was testing Ilia's patches for ddx, and while they definitely helped for Xorg itself,
qemu still eats a lot of CPU if launched like this
qemu-system-x86_64 -cdrom ~/Downloads/ISO/slax-English-US-7.0.8-x86_64.iso -m 1G -display sdl,gl=on -enable-kvm
and left for few hours.

The DDX eating CPU isn't intrinsically bad. Did you check where perf
says the CPU time is going? Could be doing copies/etc.

I think Xorg ended up eating ~13% CPU after I quit most programs, but it
was definitely better than much higher CPU usage before your patches.
I saw no additional debug messages in X log, so probably you covered
my specific case well.
qemu was eating CPU in nouveau_dri.so/libdrm_nouveau.so.2.0.0,
so I suspected something like 'too many error reports from vblanks'
may happen there, too.
Unfortunately, my standard build command for mesa included --strip,
so opreport -c was not giving any additional details ...
I just recompiled DDX again with if 0'ed debug message, will see how
it works alone, and then retry mesa build/qemu long-uptime testing ...

I think Xorg ended up eating ~13% CPU after I quit most programs, but it
was definitely better than much higher CPU usage before your patches.
I saw no additional debug messages in X log, so probably you covered
my specific case well.
qemu was eating CPU in nouveau_dri.so/libdrm_nouveau.so.2.0.0,
so I suspected something like 'too many error reports from vblanks'
may happen there, too.
Unfortunately, my standard build command for mesa included --strip,
so opreport -c was not giving any additional details ...
I just recompiled DDX again with if 0'ed debug message, will see how
it works alone, and then retry mesa build/qemu long-uptime testing ...

Update, after few hours of qemu uptime
I can see this oreport:

pixman/memcpy dominating initial profile probably OK, because guest uses vesa driver and KDE4 with 1920x1200
resolution, scaled down to my monitor resolution 1440x900 :}
I'll attach compressed oprofile directories with data (from oprofile 1.2.0)
