[Bug 1077297] Re: Unable to access debug information from modules in linux-image-extra
Sorry for the many posts, please note that the linux-image dbgsym package is _large_. linux-image-3.5.0-17-generic-dbgsym will expand to 2395318 Kbytes (yes, that's more than 2.2 Gigs), and is about a ~600MB download, so make sure you're on a fat internet pipe and have some time to spare. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077297 Title: Unable to access debug information from modules in linux-image-extra To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1077297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also, ignore the comments on kernel support and support for userspace probes, Ubuntu Quantal has both. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077297 Title: Unable to access debug information from modules in linux-image-extra To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1077297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1077297] Re: Unable to access debug information from modules in linux-image-extra
Sure :-) I followed this guide:
http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu
Make sure to substitude 'quantal' for 'precise' in the 'General ddeb repository
configuration' section.
The apt-key is the same for Quantal.
For a module in linux-image, try
$ sudo stap -L 'module("parport").function("*")'
For a module _not_ in linux-image, e.g. in linux-image-extra, try
$ sudo stap -L 'module("parport_serial").function("*")'
(Note: the -L instead of -l adds function parameter descriptions to the
output, a very cool feature :-) )

Can you provide a pointer to the documentation you followed to install the kernel dbgsym package? I'll see if I can also reproduce the issue. Also, can provide an example module from linux-image-$(uname -r) that provides it's function probes as expected? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077297 Title: Unable to access debug information from modules in linux-image-extra To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1077297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
