Is it possible that xenoprof active domain profiling using pvops jeremy's kernel

[박은병]

[-- Attachment #1.1: Type: text/plain, Size: 1073 bytes --]

my system configuration

xen 3.4.2, oprofile 0.9.5( xenoprof patched ), dom0( jeremy's pvops
kernel 2.6.31.6 - patched dullor's xenoprof patch ), domU( vanilla kernel
2.6.32 with paravirt enabled ), distribution( ubuntu 9.10 )

In passive mode, xenoprof seems to work well, opreport showed good
information.
but, in active mode, it seems not to be done correctly.

my command is strictly followed by xenoprof tutorial doc.

<dom0>
opcontrol --start-daemon --event=L2_RQSTS:100000 --xen=/boot/xen-syms-3.4.2
--vmlinux=/boot/vmlinux-2.6.31.6-xen-xenoprof --active-domains=7

<domU>
opcontrol --start --event=L2_RQSTS:100000 --xen=/boot/xen-syms-3.4.2
--vmlinux=/boot/vmlinux-2.6.32-domU
In domU, opcontrol was break showing "cannot find timer command??"

I think that domU kernel also should be patched. Is it right?? dullor's
patch available on vanilla kernel?? I had tried to patch the dullor's patch
to vanilla kernel 2.6.31.6 with 2 conflict message.(mmu.c, xen-ops.h)

is there anyone who succeed in running xenoprof in active mode using
jeremy's pvops 2.6.31.6 dom0 ??

To run xenoprof in active mode you need xenoprof support both in dom0 and in domU. Try using the the pvops kernel with Dullor's xenoprof patch in domU too. This should solve your problem...

[-- Attachment #1.1: Type: text/plain, Size: 2724 bytes --]

I tried to use same pvops kernel(jeremy's) for both dom0 and domU, and
dullor's patch.

But, it does not work well.

dom0# opcontrol --start-daemon --event=L2_RQSTS:100000
--xen=/boot/xen-syms-3.4.2 --vmlinux=/boot/vmlinux-2.6.31.6-xen-xenoprof
--active-domains=1
Using 2.6+ OProfile kernel interface.
Reading module info.
Using log file /var/lib/oprofile/samples/oprofiled.log
Daemon started.

dom0 seems to be good. I think,,

and domU command

domU# opcontrol --start --event=L2_RQSTS:100000 --xen=/boot/xen-syms-3.4.2
--vmlinux=/boot/vmlinux-2.6.31.6-domU-xenoprof
/usr/local/bin/opcontrol: line 367: timer: command not found
You cannot specify any performance counter events
because OProfile is in timer mode.

And. Some tricky output..

dom0#>cat /dev/oprofile/cpu_type
i386/core

 domU#>cat /dev/oprofile/cpu_type
timer

I would appreciate your response....:)

This seems to be related to a recently fixed bug.
Try using Xen 4.0 or latest unstable or apply the patch posted in:

Thanks. I am sorry for late response.

the patch you have mentioned is already applied.

Hum....But, I have not tried to Xen 4.0 or unstable.

Is there any other difference between the patch and 4.0 or unstable about
xenoprof.c ??

This is the only recent fix I am aware of
Active mode profiling requires carefull synchronization between dom0 and the guest domain
Make sure you follow the instructions described in:
http://www.xen.org/files/summit_3/xenoprof_tutorial.pdf

I already have strictly adhered to xenoprof_tutorial.

I also tried to apply xen-4.0.0-rc3-pre unstable version. but it is also
does not work with same error message.

I want to know your active domain profiling environment, including xen
version, dom0, domU and linux distribution.

Re: Is it possible that xenoprof active domain profiling using pvops jeremy's kernel

Hi Jose,

Did you manage to resolve the following xenoprof error:

domU# opcontrol --start --event=L2_RQSTS:100000 --xen=/boot/xen-syms-3.4.2
--vmlinux=/boot/vmlinux-2.6.
31.6-domU-xenoprof
/usr/local/bin/opcontrol: line 367: timer: command not found
You cannot specify any performance counter events
because OProfile is in timer mode.


I am facing the same problem. I am using xen-3.4.1 on dom0. Do I need to
install xen on domU as well?

My hardware is AMD-64.

Thanks for the help.
