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 &

Yes, this is a better solution for sure, to take both para-domain and
hvm into account.
But it''s not a problem for now:) _mode_ logic only applies to active
domiain. Oprofile doesn''t use it for samples between PASSIVE_START_CODE
and PASSIVE_STOP_CODE. Rather it relies on PC range to distinguish
xen/kernel/app samples.
Thanks,
Xiaowei

Lambert (1992) simulation
Hi,
I am trying to replicate Lambert (1992)'s simulation with zero-inflated
Poisson models. The citation is here:
@article{lambert1992zero,
Author = {Lambert, D.},
Journal = {Technometrics},
Pages = {1--14},
Publisher = {JSTOR},
Title = {Zero-inflated {P}oisson regression, with an application to defects
in manufacturing},
Year = {1992}}
Specifically I am trying to recreate Table 2. But my
