[XENOPROFILE] Xenoprof passive profiling broken under cs 13062
Renato,
If one creates an HVM domain (say domain 1) and then does
echo 1 > /dev/oprofile/passive_domains
one then gets the following on the Xen serial console:
(XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t
supported yet
(XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t
supported yet
(XEN) xenoprof.c:143:d0

[HVM][XENOPROFILE][RFC][0/3] xenoprofile HVM patches
Keir,
The following 3 patches allow HVM (SVM and VT) guests to be passively
profiled using the very latest patches from Renato. These patches apply
to 11470.
Renato''s patches:

And also a patch not posted FAIK
(oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached
tar.bz2 file.

Xenoprof in an HVM domain
I''m looking into getting Xenoprof to tun in an HVM domain, since we will
eventually need a profiler for HVM domains to track down areas of poor
performance. (HVMs have poor performance? :) ) Being relatively new to
OProfile, Xenoprof, and Xen internals, I would appreciate any pointers,
tips, and comments on how to work the implementation. I see three basic
areas of work.
1. Implement

xenoprof passive profiling and "mode" setting
Xiaowei,
I''m puzzled by the following bit of code in p4_check_ctrs():
if (guest_kernel_mode(current, regs))
mode = 1;
else if (ring_0(regs))
mode = 2;
If I look at the definition for guest_kernel_mode() it is:
include/asm-x86/x86_64/regs.h:
#define guest_kernel_mode(v, r) \
(ring_3(r) && ((v)->arch.flags &
