pstatectl
pstatectl(1M) pstatectl(1M)
NAME
pstatectl - control processor performance states
SYNOPSIS
cpu] pstate| interval]
DESCRIPTION
The command is used to control processor performance states (P-states). On systems with supported processors and firmware, processor per-
formance states can reduce power consumption.
A supported processor implements a series of performance states, numbered from P0 to Pn, where n is implementation dependent. Each subse-
quent P-state consumes less power but offers less performance than the previous state.
provides access to both static and dynamic performance state usage modes. In static mode, the system remains in a specified P-state, where
power consumption and performance are reduced by a fixed amount. In dynamic mode, HP-UX will adjust the processors' P-states individually,
in response to the workload running on the system.
Enabling dynamic processor performance states will generally have a negligible effect on system performance, while at the same time reduc-
ing power consumption when the system is not fully loaded.
Options
recognizes the following options:
The operation will apply to the specified
processor only. If is not specified, the operation applies to the whole system.
The "status" operation will report detailed status for each processor.
Otherwise, a summary of the system state is reported.
Operands
recognizes the following operands; only one operand at a time can be specified on the command line:
Enable the dynamic P-states mode (processors will adjust performance to match the workload).
Disable the P-states (processors will always be at maximum performance).
Enable static mode (processors will always be in the specified P-state).
If the specified state is higher than is supported, the highest supported state is used instead. The state may be
specified as a number, or in P-state notation (for example, P0).
Enable dynamic P-states mode within the range of states specified.
and should be supplied as specified under the option.
Report information about the system's P-state capabilities,
the current P-state mode (static or dynamic), and whether HP-UX has control over processor P-states. If was speci-
fied, each processor's current P-state and operating mode are displayed.
Display a table listing the power consumption and relative performance of each P-state.
Print the number of the highest implemented P-state on the system.
If the system does not support P-states, the number is 0.
Change the time interval between dynamic mode state changes to the
specified duration. The minimum is 0.01 seconds, and the maximum is 600 seconds.
EXTERNAL INFLUENCES
On some systems, the Onboard Administrator may take control of P-states away from the operating system (for instance, when iLO is used to
place the system in Static High Performance or Static Low Power mode).
If HP-UX does not have control over processor performance states, the command will still work normally. However, any changes made to
P-state modes will have no effect until HP-UX regains control. The command will report whether HP-UX currently has control over P-states.
RETURN VALUE
returns the following values:
Successful completion.
Command failed.
DIAGNOSTICS
Make sure that the system has Itanium(R) 2 9100 series or later processors, and that the installed system firmware supports P-
states.
EXAMPLES
To enable dynamic P-states on the system:
To disable dynamic P-states on the system (all processors will be in maximum performance mode):
or
To restrict the system to P0 and P1 only:
DEPENDENCIES
Processor performance states require Itanium(R) 2 9100 series processors or later models. Some systems require a firmware update to use
processor performance states.
