libpfm_amd64_fam10h - support for AMD64 Family 10h processors
SYNOPSIS
#include <perfmon/pfmlib.h>
PMU name: amd64_fam10h_barcelona, amd64_fam10h_shanghai, amd64_fam10h_istanbul
PMU desc: AMD64 Fam10h Barcelona, AMD64 Fam10h Shanghai, AMD64 Fam10h Istanbul
DESCRIPTION
The library supports AMD Family 10h processors in both 32 and 64-bit modes. They correspond to processor family 16.
MODIFIERS
The following modifiers are supported on AMD64 Family 10h (16) processors:
u Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3. This is a boolean modifier.
k Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0. This is a boolean modifier.
h Measure at while executing in host mode (when using virtualization). This corresponds to PFM_PLMH. This modifier is available
starting with Fam10h. This is a boolean modifier.
g Measure at while executing in guest mode (when using virtualization). This modifier is available starting with Fam10h. This is a
boolean modifier.
i Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier
e Enable edge detection, i.e., count only when there is a state transition. This is a boolean modifier.
c Set the counter mask value. The mask acts as a threshold. The counter will count the number of cycles in which the number of occur-
rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255].

libpfm_intel_coreduo - support for Intel Core Duo/Solo processors
SYNOPSIS
#include <perfmon/pfmlib.h>
PMU name: coreduo
PMU desc: Intel Core Duo
DESCRIPTION
The library supports all Intel Yonah-based processors such as Intel Core Duo and Intel Core Solo processors.
MODIFIERS
The following modifiers are supported on Intel Core Duo processors:
u Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3. This is a boolean modifier.
k Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0. This is a boolean modifier.
i Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier
e Enable edge detection, i.e., count only when there is a state transition. This is a boolean modifier.
c Set the counter mask value. The mask acts as a threshold. The counter will count the number of cycles in which the number of occur-
rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255].
ENVIRONMENT VARIABLES
It is possible to force activation of the Intel Core Duo support using the LIBPFM_FORCE_PMU variable. The PMU name, coreduo, must be
passed. No additional options are supported.

Hello all! My boss wants we to learn a little bit of Unix in the next couple of months so I can broaden my opportunities. What processors will Unix run on? Intel... AMD32.... AMD64... Help Please. I need to build a computer that can support Unix to begin learning. Thanks (3 Replies)
I've been searching the internet for a while, but maybe i was asking the wrong questions. so i am trying it here now :)
(1) does HP-UX run on an AMD64 System?
if so:
(2) where can i get an evaluation copy or something like that?
if not:
(3) which would be the cheapest hardware to get a... (5 Replies)

Hello Everyone,
I am new to this forum and also unix/linux. Our application today threw an alert whcih read as
"The users active count on host has crossed the threshold limit of 50
and is standing at 65."
This was although cleared when I restarted tomcat. But I am not sure why this count... (0 Replies)
