AMD® Kabini

Available performance monitors for the AMD® Kabini microarchitecture

• General-purpose counters
• L2 cache general-purpose counters
• Northbridge general-purpose counters

General-purpose counters

The AMD® Kabini microarchitecture provides 4 general-purpose counters consisting of a config and a counter register.

Counter and events

Counter name	Event name
PMC0	*
PMC1	*
PMC2	*
PMC3	*

Available Options

Option	Argument	Description	Comment
edgedetect	N	Set bit 18 in config register
kernel	N	Set bit 17 in config register
threshold	8 bit hex value	Set bits 24-31 in config register	The value for threshold can range between 0x0 and 0x3
invert	N	Set bit 23 in config register

Counters available for one hardware thread per shared L2 cache

L2 general-purpose counters

The AMD® Kabini microarchitecture provides 4 general-purpose counters for measuring L2 cache events. They consist of a config and a counter register.

Counter and events

Counter name	Event name
CPMC0	*
CPMC1	*
CPMC2	*
CPMC3	*

Available Options

Option	Argument	Description	Comment
threshold	8 bit hex value	Set bits 24-31 in config register	The value for threshold can range between 0x0 and 0x3
invert	N	Set bit 23 in config register
tid	4 bit hex value	Set bits 56-59 in config register	If bit equals 0, the events of the thread are counted. See BIOS and Kernel Developer’s Guide (BKDG) for AMD Family 16h Processors for details.
nid	4 bit hex value	Set bits 48-51 in config register	If bit equals 0, the events of the thread are counted. See BIOS and Kernel Developer’s Guide (BKDG) for AMD Family 16h Processors for details.

Counters available for one hardware thread per socket

Northbridge general-purpose counters

The AMD® Kabini microarchitecture provides 4 general-purpose counters for the Northbridge consisting of a config and a counter register.
