[PATCH 0/3] xenoprof fixes
These patches address issues in the kernel part of xenoprof:
* Ill-advised use of on_each_cpu() can lead to sleep with interrupts
disabled.
* Race conditions in active_domains code.
* Cleanup of active_domains code.
Comments welcome.

with getting llvm-config to print the right things to let external
programs link.
For some background, oprofile installs an agent library into
<prefix>/lib/oprofile/libopagent.{a,so}. This...

[PATCH] Xenoprof passive domain support
Hi Renato,
This patch is to add Xenoprof passive domain support in SMP environment.
Basically:
- It allocates per vcpu buffers for passive domain and maps them into
primary domain''s space.
- When primary domain gets sampled and triggers virq, its kernel module
will handle passive domain'' samples besides its owns. There...

simple question about xenoprof
I''m trying to use xenoprof in my machine (xeon x5650, westmere).
While oprof works for this machine correctly, xenoprof doesn''t work
properly.
I want to use xenoprof in NMI mode (which is the opposite side of timer
mode, right?)
However, kernel message always shows that xenoprof works in the timer mode...
