- Support for uncore counting events: one fixed PMC with the uncore
domain clock, 8 programmable PMC. - Westmere based CPU (Xeon 5600, Corei7 980X) support. - New man pages with events list for core and uncore. - Updated Corei7 events with Intel 253669-033US December 2009 doc. There is some removed events in the documentation, they have been kept in the code but documented in the man page as obsolete. - Offcore response events can be setup with rsp token.

+.Sh LIBRARY
+.Lb libpmc
+.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"
+.%N "Order Number: 253669-033US"
+.%D December 2009

+.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.
