RE: [Xen-devel] Is it possible that xenoprof active domain profiling using pvops jeremy's kernel

["Santos, Jose Renato G" <joserenato.santos@xxxxxx>]

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...

Subject: [Xen-devel] Is it possible that xenoprof active domain profiling using pvops jeremy's kernel

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 ??
