[Xen-devel] [PATCH] Xenoprof patches for xen-unstable
hi,
I have attached patches for enabling system wide profiling
using oprofile for xen unstable.
The patches were generated against change-set 1.1507 (May 22).
The 4 attached files are
1) xenoprof.txt:
- xenoprof overview and user guide
2) xenoprof-1.1-xen-3.0-devel.patch:
- patch for xen
3) xenoprof-1.1-linux-2.6.11:
- patch for linux. Note that this needs to be applied
twice, once to linux-2.6.11-xen0 and once to
linux-2.6.11-xenU. (This is different than the last
patch which was created against the linux sparse tree).
4) xenoprof-1.1-oprofile-0.8.2:
- patch for oprofile version 0.8.2
Current known limitation/bugs are
- No support for SMP guests yet.
- when using passive domains, most samples are lost.
I will be working on these issues and post new patches
when I have them available.
Thanks
Renato

We call passive domains domains that are profiled but do not have support for collecting PC samples (i.e they do not have oprofile running). In this case their samples are sent to the initiator domain (usually domain 0) which process the samples on their behalf. In this case the samples are not decoded to specific binary files/functions but are assigned to the whole domain (coarse granularity profiling). We are planning to enable fine granularity profiling for the kernel code on passive domains in the future. However, as I mentioned, xenoprof is not working properly with passive domains yet. In the normal mode of operation that is functional at this time, every domain being profiled must be running an oprofile kernel module to process the PC samples generated when they are running. Each domain will have a partial report of the samples that happened when they were running. System wide profiling is obtained by combining the reports of all profiled domains. I hope this is clearer now.

Speaking for myself, neither of the above will be an issue, since we can run oprofile on all the kernels and are not yet running SMP guests. Many thanks!

I am using these on xen-unstable-bk-1.1518 currently. One problem: so far I have not observed any ticks in xen-syms. I have tried SDET benchmark, which on your previous patches (for xen-2.0-testing), I would get about 12% of ticks in xen-syms. This is on a single cpu xen0 domain with no other domains running. I verified that the XENIMAGE and XEN_RANGE were getting passed to oprofiled correctly. I do not specify any active or passive domains since this is the only domain running. Any ideas why I would not get any ticks for xen-syms? Has anyone else tried xenoprofile?

Andrew This is weird. Something seems wrong. I am not familiar with the benchmark you are running. Is this something easy to try? If you could send me the code and some instructions on how to use it, I can try running the same benchmark in my environment. I will also spend sometime looking more carefully at xenoprof and my tests to see if I find anything wrong Renato>> -----Original Message----- >> From: Andrew Theurer [mailto:habanero@us.ibm.com] >> Sent: Tuesday, May 31, 2005 9:08 AM >> To: Santos, Jose Renato G >> Cc: Xen-devel@lists.xensource.com >> Subject: Re: [Xen-devel] [PATCH] Xenoprof patches for xen-unstable >> >> >> On Wednesday 25 May 2005 14:10, Santos, Jose Renato G wrote: >> > hi, >> > >> > I have attached patches for enabling system wide profiling >> > using oprofile for xen unstable. >> > The patches were generated against change-set 1.1507 (May 22). >> > The 4 attached files are >> > >> > 1) xenoprof.txt: >> > - xenoprof overview and user guide >> > 2) xenoprof-1.1-xen-3.0-devel.patch: >> > - patch for xen >> > 3) xenoprof-1.1-linux-2.6.11: >> > - patch for linux.
