ACPI 4.0 POWER METER DRIVER
Search everywhere only in this topic. They're not in the processor. Right now we're simulating the meters in kvm until we get real hardware, though it could be a mechanism to report per-VM power use. Pavel Machek. Will it wake from sleep? PMI events, such as when power thresholds are exceeded, are signaled through a set of ACPI acpi 4.0 power meter codes on the power meter device.
Each ACPI PMI namespace object has appropriate control methods that allow interactions between the operating system and the hardware platform. At that point, a management processor adjusts CPU P-states and clock throttling to limit the power consumed. acpi 4.0 power meter
That shows a GUI. I did attach the screenshot.
Processor power states C-states vs. What triggers a CPU core to enter Cx-state? Is it possible to disable C-states so always C0 is used? How does acpi 4.0 power meter these actually work, for example in Linux? How can I monitor my CPU? Introduction How does CPU save power? How to decrease CPU power consumption while it is operating? Pleak is proportional to the voltage. Will it wake from sleep?

Document that. So it goes with ACPI. Power consumption is monitored, or meteredby a power meter in the system.
Power metering also provides the current configuration of acpi 4.0 power meter power meter, such as metering capabilities and power consumption thresholds. Power Budgeting Information This information is used to determine the power limit, or budgetthat is supported by the computer system.
Hierarchy of software components used in power management. Microcode Update There may be cases where it is necessary to change the behavior of hardware power management features—to fix issues, to add new functionality, or to optimize feature use. A resource can only be in one state type at any given time. For example, a system can only be in one S-state at a time, a core can only acpi 4.0 power meter in one P-state at a time, and a device can only be in one D-state at a time.
[PATCH 0/2] ACPI 4.0 power meter
Figure illustrates the relationships and dependencies between S-states, C-states, and P-states and how a system transitions between them. Summary of ACPI power states and transitions.
Note Use of S3 and S4 is uncommon in servers. BIOS firmware is responsible for constructing these tables and loading them into memory where the operating acpi 4.0 power meter reads them and enumerates capabilities. These tables consist of several objects that provide needed power state and control information to the OS.
Acpi power meter driver
Note There are many cases where exposing Turbo as a single P-state is not energy efficient.The ACPI PMI is provided by the ACPI Power Metering objects. These objects provide an abstraction layer to the protocol that acpi 4.0 power meter used for. The second patch implements a hwmon driver for ACPI compliant power meters that uses the expanded sysfs interface. I don't have an.
