cpumf_helper - Helper module for managing CPU-Measurement Facilities (CPU-MF)
|
||||
|
||||
Options:
|
||||
-i, --info:
|
||||
Displays detailed information about installed and available
|
||||
CPU-measurement facilities and the related Linux support.
|
||||
|
||||
-c, --counter authorization_value
|
||||
Displays counter information for the current System z hardware.
|
||||
The authorization value provides information about the authorized
|
||||
counter sets. The value must be specified in decimal format.
|
||||
|
||||
To display all supported counters, specify C<65535> (FFFF hex).
|
||||
|
||||
To display supported counters for a particular System z hardware,
|
||||
use the --ctr-def option and specify the System z hardware type.
|
||||
|
||||
--hardware-type
|
||||
Displays the System z hardware type.
|
||||
|
||||
--ctr-def ctr-definition
|
||||
Displays detailed information about the specified counter definition.
|
||||
Valid counter definitions start with C<cfvn-> or <csvn-> followed by
|
||||
the counter first/second version number of the CPU-Measurement Counter
|
||||
Facility. To display counter information of model-specific counter
|
||||
sets, specify the System z hardware type for I<ctr-definition>.
|
||||
|
||||
--ctr-set-names
|
||||
Displays the mapping of counter set IDs to counter set names.
|
||||
The counter set IDs are numbers that are used in counter definitions.
|
||||
|
||||
--ctr-set-ids
|
||||
Displays the counter set IDs. The counter set IDs are numbers that
|
||||
match the authorization bits (see QUERY COUNTER INFORMATION).
|
||||
The output format is a list. To get the ID for a particular counter
|
||||
set, use an index number as follows:
|
||||
|
||||
0: Basic Counter Set
|
||||
1: Problem-State Counter Set
|
||||
2: Crypto-Activity Counter Set
|
||||
3: Extended Counter Set
|
||||
4: MT-diagnostic Counter Set
|
||||
5: Coprocessor Group Counter Set
|
||||
|
||||
--ctr-sf
|
||||
Displays the counter definitions for the sampling facility support.
|
||||
These counter definitions are specific to Linux perf infrastructure.
|
||||
|
||||
--sfb-size
|
||||
Displays the size of the sampling facility buffer (SFB). The minimum
|
||||
and maximum numbers are measured in units of sample-data-blocks. A
|
||||
sample-data-block uses about 4 kilobytes.
