.Sh SYNOPSIS
|
|
.In pmc.h
|
|
.Sh DESCRIPTION
|
|
Each fixed-function PMC measures a specific hardware event.
|
|
The number of fixed-function PMCs implemented in a CPU can vary.
|
|
The number of fixed-function PMCs present can be determined at runtime
|
|
by using function
|
|
.Xr pmc_cpuinfo 3 .
|
|
.Pp
|
|
Intel uncore fixed-function PMCs are documented in
|
|
.Rs
|
|
.%B "Intel(R) 64 and IA-32 Architectures Software Developes Manual"
|
|
.%T "Volume 3B: System Programming Guide, Part 2"

|
|
.Ss Class Name Prefix
|
|
These PMCs are named using a class name prefix of
|
|
.Dq Li ucf- .
|
|
.Ss Event Specifiers (Fixed Function PMCs)
|
|
The fixed function PMCs are selectable using the following
|
|
event names:
|
|
.Bl -tag -width indent
|
|
.It Li UCLOCK
|
|
.Pq Fixed Function Counter 0
|
|
The fixed-function uncore counter increments at the rate of the U-clock.
|
|
The frequency of the uncore clock domain can be determined from the uncore
|
|
clock ratio which is available in the PCI configuration space register at
|
|
offset C0H under device number 0 and Function 0.
