I am forwarding this to Mathieu just in case he is not following the
SystemTap mailing list. Please include him in future markers discussion.
Mathieu, as you can see we are adding the support for markers in the
SystemTap and also trying to add markers patches to the kernel.
Are we using the latest version of the markers patch or do you have more
updated versions?
If we find bugs while using markers can we open them in the SystemTap
bugzilla?
Thanks,
Vara Prasad

What's the status of kernel marker support in SystemTap? Should
kernel.mark("<name>") work with Mathieu's latest patches? Just
curious because I tried and I'm seeing "no match for probe point"
errors for markers I added to the kernel.
Mike,
As the ChangeLog says, I updated the markers support on 9/25/2007 to
work with Mathieu's 9/18/2007 markers patch.
Sorry, I missed the ChangeLog entries.
So, are you using a version of systemtap that has those changes present?
Yes, I'm using the latest cvs code.
Which version of Mathieu's markers patch are you using?
I'm using the latest marker patches posted on 9/28.
Thanks,
Mike
