OProfile patch for Linux 2.6.39.rc5.git5

OProfile patch for Linux 2.6.39.rc5.git5

[W. Michael Petullo]

I have ported Anil's passive profile-capable OProfile patch to Linux
2.6.39.rc5.git5. Please see:

	http://www.flyn.org/patches/linux-2.6.39.rc5.git5-xen-passive-oprofile/linux-2.6.38-xen-passive-oprofile.patch.gz

With this patch applied to Linux 2.6.39.rc5.git5, I can perform passive
profiling on an unprivileged Xen domain.

Hi, Michael,
The link does not work.
And is this a dom0 kernel?

Sorry, the link should have been:

	http://www.flyn.org/patches/linux-xen-passive-oprofile/linux-2.6.39.rc5.git5-xen-passive-oprofile.patch.gz

> And is this a dom0 kernel?

Yes. This is a patch against linux-2.6.39.rc5.git5. This feature is
relavent when Linux is built to be run in Dom0.

This is cool, given that Jeremy's dom0 kernel is based on only 2.6.32.

Is there a git of this by any chance? BTW, when I ran diffstat on this I saw

..
 arch/x86/include/asm/xen/hypercall.h.orig |  565 ++++++
 arch/x86/xen/mmu.c.orig                   | 2486 ++++++++++++++++++++++++++++++
 include/linux/oprofile.h.orig             |  211 ++

I don't think the .orig file are neccessary?

The git repository is https://github.com/avsm/linux-2.6.32-xen-oprofile
But it is for 2.6.32.

Were you thinking to establish one for the 2.6.39 tree by any chance?

Re: OProfile patch for Linux 2.6.39.rc5.git5

[Steven]

Yes, I am working on it now and will post a git patch against the 2.6.39 tree.
