[Xen-ia64-devel] [RFC][PATCH 0/10] xenoprof for Xen/IA64

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi all
This patch set is for Xen/IA64 xenoprof.
Although those patches are still ugly and many clean ups must be done
before commit, I think others may need xenoporf.
So I decided to send out this patchset.

NOTE:
oprofile-0.9.2 is required to the patch from
http://xenoprof.sourceforge.net/oprofile-0.9.2-xen.patch


TODO:
- more clean ups
- separate common code and arch specific code.
- up-port
- perfmon2
  It seems that perfmon2 goes to arch-generic.


output example:
