[Perfinsp-list] patches for 2.6.27

From: Maynard Johnson <maynardj@us...> - 2008-10-13 18:43

Attachments: itrace-on_each_cpu-fix.patch itrace-nopage.patch

Milena,
Attached are two patches that address kernel API changes in recent kernels, 
allowing the ITrace component of Performance Inspector tools to build 
successfully.  The two API changes were:
  1) on_each_cpu, went from 3 parameters to 2
  2) nopage was replaced with fault

I've not made any attempt to add any type of conditional compilation for these 
changes (basing on kernel level), but this obviously needs to be done.

Thanks.

[Perfinsp-list] Need to support changes in recent kernel version

From: Maynard Johnson <maynardj@us...> - 2008-10-09 16:39

Hello,
In our present effort to upgrade the ITrace package for SLES 11, the Novell guy I'm working with has brought to my attention some changes needed in Performance Inspector code to support the kernel version used in SLES 11 -- i.e., 2.6.27.  For example, on_each_cpu only has two parameters now, instead of 3; and the nopage API has been removed (replaced, I think, with "fault").

I will work on some patches that are needed for 2.6.27 and post them to this list.  Then, can you determine how to integrate them into the source (i.e., how to conditionally compile, based on kernel version)?

Thanks.

Hi Maynard,

Sure, will do that.
We need to upgrade the pitrace driver to work with the newer kernels 
anyway.

[Perfinsp-list] [PATCH] additional changes needed for Fedora stapitrace rpm

From: Maynard Johnson <maynardj@us...> - 2008-10-02 18:13

Attachments: itrace_fedora-july-fix.patch

Milena,
Attached is a patch that is currently being applied on top of Performance 
Inspector code for the Fedora 10 stapitrace rpm that Dave Nomura put together. 
We will now be submitting the same code base to Red Hat for RHEL 6, but I'm sure 
they will insist that all code be upstream.  Can you please review this patch at 
your earliest convenience?

Thanks.
-Maynard
