xenoprof patch for oprofile-0.9.7
I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5. I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a...

[LLVMdev] oprofile support?
I've been trying to get oprofile results for jitted code without success. I built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a small test case. I built the latest oprofile from the git repository. Debugging I can see that lli is registering the listener and making the oprofile calls to the libopagent api to s...

[LLVMdev] oprofile support?
Mi Maurice, A follow up to Andy's comments: MCJIT can find line numbers for ELF files, at least in limited circumstances. I know because I broke the regression test for it while doing some cleanup recently. ;) Looking at lib/ExecutionEngine/OProfileJIT/OProfileJITEventListener.cpp, I see the line: // TODO: support line number info (similar to IntelJITEventListener.cpp) >From a glance at IntelJITEventListener, I think it would be easy to copy the line number support in there over to OProfileJITEventListener. Cheers, Lang. On Fri, Oct 1...

[HVM][XENOPROFILE][RFC][0/3] xenoprofile HVM patches
Keir, The following 3 patches allow HVM (SVM and VT) guests to be passively profiled using the very latest patches from Renato. These patches apply to 11470. Renato''s patches: http://xenoprof/sourceforge.net oprofile-0.9.1-xen-r2.patch And also a patch not posted FAIK (oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached tar.bz2 file. hvm_xenoprofile_1.patch - The first patch is merely the same patch that I posted a few weeks ago. The STGI code is moved from the exits.S files, and into the vmexi...

yum install oprofile-gui
Nicolas Thierry-Mieg, We followed your instructions to yum install oprofile-gui. We were able to install oprofile-guii.i386 0:0.9.4-15.el5.centos and oprofile.i386 0.0.9.4.15.el.5.centos. I was wondering what our next step should be. I tried ./configure --with-kernel-support with oprofile-0.9.6 and obtain a warning, a working QT not found, no GUI was built. Should w...

[PATCH] Xenoprof passive domain support
...main'' samples besides its owns. There is potential buffer overflow if passive is very busy while primary is idle. The simple workaround is to allocate a rather big buffer for passive. For now it works fine. A better way is to notify primary when passive buffer exceeds the threshold. - When oprofile gets passive domain samples, it splits them in to 3 parts by PC ranges pre-definition: xen/kernel/application and maps the first two into functions. The oprofile version is a little old, for the patch was made last August. The main usage is to use Xenoprof to profile HVM domain as passive domain,...

FW: oprofile 0.9.3 xen symbols incorrect
Hi I am using oprofile 0.9.3 on xen cs 16540 on an Intel system. When I look at the top "hot" functions, I see p2m_change_type being one of the top function in xen-syms. This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all w...

Xen and Oprofile

[PATCH] Fix Xen panic with oprofile
The attached patch fixes a Xen panic when a domain is shutdown before oprofile is stopped. Without this patch, free_xenoprof_pages() is called before the domain is destroyed and that, in turn, prevents oprofile from cleaning up pages shared with guests. Shutting down a domain without terminating oprofile therefore causes a Xen panic at a later point in time. The patch was ge...

[LLVMdev] Profiling LLVM JIT code
Thanks for the info. I am using old JIT. So that should not be a problem. I will take a look at using oprofile. I have never used it - so will be somewhat of a learning curve. I notice that the configure script has a --with-oprofile option. In addition to enabling that, is there something else that also needs to be done? My copy of LLVM is compiled with --enable-optimized. Will --with-oprofile work fine wi...
