.Dd March 30, 2010 .Dt PMC.UCF 3 .Os .Sh NAME .Nm pmc.ucf .Nd measurement events for .Tn Intel uncore fixed function performance counters. .Sh LIBRARY .Lb libpmc .Sh SYNOPSIS n 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 .
p 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 .%Q "Intel Corporation" .Re
p .Ss PMC Capabilities Fixed-function PMCs support the following capabilities: l -column "PMC_CAP_INTERRUPT" "Support" t Em Capability Ta Em Support t PMC_CAP_CASCADE Ta No t PMC_CAP_EDGE Ta No t PMC_CAP_INTERRUPT Ta No t PMC_CAP_INVERT Ta No t PMC_CAP_READ Ta Yes t PMC_CAP_PRECISE Ta No t PMC_CAP_SYSTEM Ta No t PMC_CAP_TAGGING Ta No t PMC_CAP_THRESHOLD Ta No t PMC_CAP_USER Ta No t PMC_CAP_WRITE Ta Yes .El .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: l -tag -width indent t Li UCLOCK
q 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. .El .Sh SEE ALSO .Xr pmc 3 , .Xr pmc.atom 3 , .Xr pmc.core 3 , .Xr pmc.core2 3 , .Xr pmc.iaf 3 , .Xr pmc.k7 3 , .Xr pmc.k8 3 , .Xr pmc.p4 3 , .Xr pmc.p5 3 , .Xr pmc.p6 3 , .Xr pmc.corei7 3 , .Xr pmc.corei7uc 3 , .Xr pmc.westmere 3 , .Xr pmc.westmereuc 3 , .Xr pmc.soft 3 , .Xr pmc.tsc 3 , .Xr pmc_cpuinfo 3 , .Xr pmclog 3 , .Xr hwpmc 4 .Sh HISTORY The .Nm pmc library first appeared in .Fx 6.0 . .Sh AUTHORS The .Lb libpmc library was written by .An "Joseph Koshy" .Aq jkoshy@FreeBSD.org .
