[Qemu-devel] /proc/cpuinfo 0.000 MHz bug

[Qemu-devel] /proc/cpuinfo 0.000 MHz bug

[Alexander E. Patrakov]

My x86 host is unstable Debian Linux, and the guest is Linux From Scratch
(post-6.0 SVN). Both use linux-2.6.10, qemu is compiled by myself from the
current CVS source (not the Debian package).

The problem is the following output from cat /proc/cpuinfo in the guest
(note 0.000 MHz):

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 3
model name      : Pentium II (Klamath)
stepping        : 3
cpu MHz         : 0.000

Same thing happens when I run the same 32-bit guest in qemu-system-x86_64:

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 2
model name      : A
stepping        : 3
cpu MHz         : 0.000
cache size      : 0 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes

bogomips        : 86.27

Could you please fix this? The host is:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 11
model name      : Intel(R) Celeron(TM) CPU                1200MHz
