@ -7,9 +7,9 @@ Changes after 2.3.5 release:
--enable-popcnt
- Implemented MTRR emulation, to enable use --enable-mtrr configure
option. MTRRs is enabled by default when cpu-level >= 6.
- Implemented MONITOR/MWAIT instructions including optimized MWAIT CPU
state and hardware monitoring of physical address range, to enable
use --enable-monitor-mwait configure option
- Implemented experimental MONITOR/MWAIT support including optimized
MWAIT CPU state and hardware monitoring of physical address range,
to enable use --enable-monitor-mwait configure option.
- Removed hostasm optimizations, after Bochs rebenchmarking it was found
that the feature bringing no speedup or even sometimes slowes down
the emulation !
