libpfm_intel_x86_arch - support for Intel X86 architectural PMU
SYNOPSIS
#include <perfmon/pfmlib.h>
PMU name: ix86arch
PMU desc: Intel X86 architectural PMU
DESCRIPTION
The library supports any processor implementing the Intel architectural PMU. This is a minimal PMU with a variable number of counters but
predefined set of events. It is implemented in all recent processors starting with Intel Core Duo/Core Solo.
It acts as a default PMU support in case the library is run on a very recent processor for which the specific support has not yet been
implemented.
MODIFIERS
The following modifiers are supported on Intel architectural PMU:
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].
t Measure on both threads at the same time assuming hyper-threading is enabled. This modifier requires at least version 3 of the
architectural PMU. This is a boolean modifier.

libpfm_intel_p6 - support for Intel P5 based processors
SYNOPSIS
#include <perfmon/pfmlib.h>
PMU name: pm, ppro, pii, piii, p6
PMU desc: Intel Pentium M, Intel Pentium Pro, Intel Pentium II, Intel Pentium III, Intel P6
DESCRIPTION
The library supports all Intel P6-based processors all the way back to the Pentium Pro. Although all those processors offers the same PMU
architecture, they differ in the events they provide.
MODIFIERS
The following modifiers are supported on all Intel P6 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

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-

Hello,
I am running SCO Operserver 5.0.7 on a computer that has a Intel Duo core processor. The BIOS supports Intel Speedstep which is similar to Intel Hyperthreading and it is enabled.
In the boot file I added
