pmc.k7
PMC.K7(3) BSD Library Functions Manual PMC.K7(3)
NAME
pmc.k7 -- measurement events for AMD Athlon (K7 family) CPUs
LIBRARY
Performance Counters Library (libpmc, -lpmc)
SYNOPSIS
#include <pmc.h>
DESCRIPTION
AMD K7 PMCs are present in the AMD Athlon series of CPUs and are documented in: AMD Athlon Processor x86 Code Optimization Guide, Publication
No. 22007, Advanced Micro Devices, Inc., February 2002.
PMC Features
AMD K7 PMCs are 48 bits wide. Each K7 CPU contains 4 PMCs with the following capabilities:
Capability Support
PMC_CAP_CASCADE No
PMC_CAP_EDGE Yes
PMC_CAP_INTERRUPT Yes
PMC_CAP_INVERT Yes
PMC_CAP_READ Yes
PMC_CAP_PRECISE No
PMC_CAP_SYSTEM Yes
PMC_CAP_TAGGING No
PMC_CAP_THRESHOLD Yes
PMC_CAP_USER Yes
PMC_CAP_WRITE Yes
Event Qualifiers
Event specifiers for AMD K7 PMCs can have the following optional qualifiers:
count=value
Configure the counter to increment only if the number of configured events measured in a cycle is greater than or equal to value.
edge Configure the counter to only count negated-to-asserted transitions of the conditions expressed by the other qualifiers. In other
words, the counter will increment only once whenever a given condition becomes true, irrespective of the number of clocks during
which the condition remains true.
inv Invert the sense of comparison when the ``count'' qualifier is present, making the counter to increment when the number of events per
cycle is less than the value specified by the ``count'' qualifier.
os Configure the PMC to count events happening at privilege level 0.
unitmask=mask
This qualifier is used to further qualify a select few events, ``k7-dc-refills-from-l2'', ``k7-dc-refills-from-system'' and
``k7-dc-writebacks''. Here mask is a string of the following characters optionally separated by '+' characters:
m Count operations for lines in the ``Modified'' state.
o Count operations for lines in the ``Owner'' state.
e Count operations for lines in the ``Exclusive'' state.
s Count operations for lines in the ``Shared'' state.
i Count operations for lines in the ``Invalid'' state.
If no ``unitmask'' qualifier is specified, the default is to count events for caches lines in any of the above states.
usr Configure the PMC to count events occurring at privilege levels 1, 2 or 3.
If neither of the ``os'' or ``usr'' qualifiers were specified, the default is to enable both.
AMD K7 Event Specifiers
The event specifiers supported on AMD K7 PMCs are:
k7-dc-accesses
(Event 40H) Count data cache accesses.
k7-dc-misses
(Event 41H) Count data cache misses.
k7-dc-refills-from-l2 [,unitmask=mask]
(Event 42H) Count data cache refills from L2 cache. This event may be further qualified using the ``unitmask'' qualifier.
k7-dc-refills-from-system [,unitmask=mask]
(Event 43H) Count data cache refills from system memory. This event may be further qualified using the ``unitmask'' qualifier.
k7-dc-writebacks [,unitmask=mask]
(Event 44H) Count data cache writebacks. This event may be further qualified using the ``unitmask'' qualifier.
k7-hardware-interrupts
(Event CFH) Count the number of taken hardware interrupts.
k7-ic-fetches
(Event 80H) Count instruction cache fetches.
k7-ic-misses
(Event 81H) Count instruction cache misses.
k7-interrupts-masked-cycles
(Event CDH) Count the number of cycles when the processor's IF flag was zero.
k7-interrupts-masked-while-pending-cycles
(Event CEH) Count the number of cycles interrupts were masked while pending due to the processor's IF flag being zero.
k7-l1-and-l2-dtlb-misses
(Event 46H) Count L1 and L2 DTLB misses.
k7-l1-dtlb-miss-and-l2-dtlb-hits
(Event 45H) Count L1 DTLB misses and L2 DTLB hits.
k7-l1-itlb-misses
(Event 84H) Count L1 ITLB misses that are L2 ITLB hits.
k7-l1-l2-itlb-misses
(Event 85H) Count L1 (and L2) ITLB misses.
k7-misaligned-references
(Event 47H) Count misaligned data references.
k7-retired-branches
(Event C2H) Count all retired branches (conditional, unconditional, exceptions and interrupts).
k7-retired-branches-mispredicted
(Event C3H) Count all mispredicted retired branches.
k7-retired-far-control-transfers
(Event C6H) Count retired far control transfers.
k7-retired-instructions
(Event C0H) Count all retired instructions.
k7-retired-ops
(Event C1H) Count retired ops.
k7-retired-resync-branches
(Event C7H) Count retired resync branches (non control transfer branches).
k7-retired-taken-branches
(Event C4H) Count retired taken branches.
k7-retired-taken-branches-mispredicted
(Event C5H) Count mispredicted taken branches that were retired.
Event Name Aliases
The following table shows the mapping between the PMC-independent aliases supported by Performance Counters Library (libpmc, -lpmc) and the
underlying hardware events used.
Alias Event
branches k7-retired-branches
branch-mispredicts k7-retired-branches-mispredicted
dc-misses k7-dc-misses
ic-misses k7-ic-misses
instructions k7-retired-instructions
interrupts k7-hardware-interrupts
unhalted-cycles (unsupported)
