Hi I am still having trouble getting Windows 10 and Windows 7 laptops to communicate with a Samba server (4.1.17-Debian) running on Rasbian Jesse. Running Wireshark on one of the laptops I notice these sequential packet transfers: Laptop –> Pi BJNP Scanner command: discover Pi –> Laptop ICMP 'Destination unreachable (Port unreachable)' This happens even on a laptop

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

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 we try to build

Hello Xenoprof Users, Can someone please verify the steps to get a oprofile session profile multiple sessions? I am using a file VBD for spawning two guest OS domains on the host. I am doing the following: 1.) On dom0 Opcontrol --xen=/boot/xen-syms-blah 2.) On domU domID: 41 Opcontrol --vmlinux=/boot/vmlinux-2..blah 3.) On domU domID: 42 Opcontrol

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 specify the names and address ranges of jit'd routines, and

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 generated against Xen

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

I'm adding OProfile support to the JIT (patch at http://codereview.appspot.com/89041), and I'm running into trouble with getting llvm-config to print the right things to let external programs link. For some background, oprofile installs an agent library into <prefix>/lib/oprofile/libopagent.{a,so}. This isn't on the loader's default search path, even if <prefix>==/usr,

Hi, I have tried to profile xapian, according to the Wiki: http://trac.xapian.org/wiki/ProfilingXapian, we can profiling I/O bound cases with oprofile, but from many other articles, it seems that we can not do it in oprofile. I have followed that wiki page, installed oprofile and libc6-dbg, but it doesn't work, only CPU bound functions are counted. Anyone know how to count I/O cost in

Dear experts, to monitor performance of applications on our private clouds I decided to use Xenoprof. For that, I installed patched OProfile 0.9.5 on Dom0 and DomU. Then, I started the daemon on Dom0 opcontrol --start-daemon --active-domains=1 --separate=library --event=LLC_MISSES:90000 and received the following error: /usr/local/bin/opcontrol: line 1171: echo write error: invalid

Philip Schaffner, Thank you for your reply. I guess we will have to wait until Centos 6 arrives to get a working QT. Did you see Nicolas Thierry-Mieg's response regarding 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. Thank you. -------------- next part -------------- An HTML attachment was

Hi Priyendra, There is support for oprofile and Intel(r) VTune(tm) Performance Analyzer, but either one needs to be explicitly turned on during the build process. If you use MCJIT (as opposed to the older JIT) then oprofile support isn't in place yet. Both of these work by providing a JITEventListener that receives notification when new code is emitted and hooks it up to the profiling tool

Helps if I send it to the list....

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 desire to get this into upstream oprofile? Or should the

Hi I am trying to use oprofile with centos 6.0. I know that the debug-info for the kernel is not available, so I believe I used the correct switches to account for this. here is my script... # reset everything opcontrol --shutdown rm /root/.oprofile/da* opcontrol --separate=kernel --no-vmlinux opcontrol --event=CPU_CLK_UNHALTED:100000 opcontrol --start sleep 5
