Hi,

When I modprobe oprofile in do= main0, the dmesg show below:

[ro= ot@sd02138 ~]# dmesg | tail -n 3=0A
sha256_ssse3: Using SSSE3 optimized SHA-256 implemen= tation=0A
SELinux: initialized (dev cifs, type cifs), uses= genfs_contexts=0A
oprofile= : using timer interrupt.

But in doma= inU it the oprofile using the NMI interrup rightly.

[root@Domain1 ~]# modprobe oprofile

[root@Domain1 ~]# dmesg | = tail -n 3 =0A
CIFS VFS: default security mechanism requested. Th= e default security mechanism will be upgraded from ntlm to ntlmv2 in kerne= l release 3.3=0A
SELinux: initialized (dev cifs, type cifs), uses= genfs_contexts=0A
oprofile: using NMI in= terrupt.

<= br>

I have patch the oprofile correctly,the opcontrol= show:

[root= @sd02138 ~]# opcontrol

=A1=AD=A1=AD

--xen=3Dfile Xen image (for Xen = only)

--active-domains=3Did[,ids] list of domains= in multiple domain profiling session (Xen)=0A

--passive-domains=3Did[,ids] list of domains to be profile= d (Xen).=0A
or --domains=3Did[,ids] (coarse profiling of use= r level and kernel modules code)=0A
(n= o need to run oprofile on these domains)=0A
--passive-images=3Dfile[= ,files] list of kernel images associated with each passive domain=0A
= or =0A

--domain-images=3Dfile= [,files]ll patch the oprofile correctly,the opcontrol show:

cpu flags showed the apic flag

Does xenoprof = does not supprot X86_64?
