Package: qemu
Version: 0.10.0-1
Severity: normal
Hi,
I don't knwo what is exactly wrong but this release is more slow than the
previous 0.9.1-10. Bogomips is 788.48 in 0.9.1 and 470.01 in 0.10.0
My command line :
qemu-system-mipsel -M malta -kernel vmlinux-2.6.26-1-4kc-malta -hda Mipsel.qcow
-append "root=/dev/hda1 console=ttyS0" -nographic -m 256 -net nic -net tap
A cat /proc/cpuinfo show the problem :

Here are the values I get with 0.9.1, 0.10.0 and 0.11.0:
0.9.1
| $ cat /proc/cpuinfo
| system type : MIPS Malta
| processor : 0
| cpu model : MIPS 24K V0.0 FPU V0.0
| BogoMIPS : 653.31
| wait instruction : yes
| microsecond timers : yes
| tlb_entries : 16
| extra interrupt vector : yes
| hardware watchpoint : yes
| ASEs implemented :
| shadow register sets : 1
| core : 0
| VCED exceptions : not available
| VCEI exceptions : not available
0.10.0
| $ cat /proc/cpuinfo
| system type : MIPS Malta
| processor : 0
| cpu model : MIPS 24K V0.0 FPU V0.0
| BogoMIPS : 403.45
| wait instruction : yes
| microsecond timers : yes
| tlb_entries : 16
| extra interrupt vector : yes
| hardware watchpoint : yes
| ASEs implemented :
| shadow register sets : 1
| core : 0
| VCED exceptions : not available
| VCEI exceptions : not available
0.11.0
| $ cat /proc/cpuinfo
| system type : MIPS Malta
| processor : 0
| cpu model : MIPS 24K V0.0 FPU V0.0
| BogoMIPS : 663.55
| wait instruction : yes
| microsecond timers : yes
| tlb_entries : 16
| extra interrupt vector : yes
| hardware watchpoint : yes
| ASEs implemented :
| shadow register sets : 1
| core : 0
| VCED exceptions : not available
| VCEI exceptions : not available
As you can see the BogoMIPS is back to the previous value with this new
version.
