Hi.
I have tried to make a hack to remove support USER_MODE.
Result: +10% speed up.
From "checkit" test (REMOVED_USER_MODE/Original Qemu)
CPU: 1000825/98222
FPU: 46374.5/43146.3
VGA BIOS: 25273/24590
VGA direct: 922850/901061
HD direct: 89902.8/68978.7
The method is: removed all "env" usage.
ftp://ftp.simtreas.ru/pub/my/qemu/
have nouserhack.sh for demonstrate changes
to I386-I386-softmmu qemu.
Also. I have placed "checkit" to ftp.
Its a check program show problem with test cirrus-VGA for
some old modes, original VGA emulator give more true.
(Warning, AIO_patch from this URL very outdate. Don`t use,
for demo only!)
