FIELD
This disclosure relates generally to Information Handling Systems (IHSs), and more specifically, to systems and methods for thermal zone controls based on IHS posture in heterogenous computing platforms.
BACKGROUND
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store it. One option available to users is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated.
Variations in IHSs allow for IHSs to be general or configured for a specific user or specific use, such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Historically, IHSs with desktop and laptop form factors have had full-fledged Operating Systems (OSs) (e.g., WINDOWS, LINUX, MAC OS, etc.) executed on “×86” processors. Other types of processors, such as ARM processors, have been associated with smartphones and tablet devices, which typically carry thinner, simpler, or mobile OSs (e.g., ANDROID, IOS, WINDOWS MOBILE, etc.). In recent years, however, IHS manufacturers have started releasing desktop and laptop IHSs equipped with ARM processors, and newer OSs (e.g., WINDOWS on ARM) can now provide users with a more quintessential OS experience on those IHSs.
The inventors hereof have recognized that the IHS industry's transition from ×86 to ARM-based processors has created new management, customization, optimization, interaction, servicing, and configuration opportunities for IHS users, Information Technology Decision Makers (ITDMs), and Original Equipment Manufacturers (OEMs).
SUMMARY
Systems and methods for thermal zone controls based on Information Handling System (IHS) posture in heterogenous computing platforms are described. In an illustrative, non-limiting embodiment, an IHS may include: a heterogeneous computing platform having a plurality of devices; and a memory coupled to the heterogeneous computing platform, where the memory comprises firmware instructions that, upon execution by at least one of the plurality of devices, causes the at least one device to operate as an orchestrator configured to: detect a change to an IHS posture; and in response to the detection, modify an Advanced Configuration and Power Interface (ACPI) thermal zone setting.
The heterogeneous computing platform may include: a System-On-Chip (SoC), a Field-Programmable Gate Array (FPGA), or an Application-Specific Integrated Circuit (ASIC). The orchestrator may include at least one of: a sensing hub, an Embedded Controller (EC), or a Baseboard Management Controller (BMC).

The modification to the ACPI thermal zone setting may include a modification of a trip point associated with an ACPI thermal zone. Additionally, or alternatively, the modification to the ACPI thermal zone setting may include a modification to a mitigation action associated with an ACPI thermal zone.

The terms “heterogenous computing platform,” “heterogenous processor,” or “heterogenous platform,” as used herein, refer to an Integrated Circuit (IC) or chip (e.g., a System-On-Chip or “SoC,” a Field-Programmable Gate Array or “FPGA,” an Application-Specific Integrated Circuit or “ASIC,” etc.) containing a plurality of discrete processing circuits or semiconductor Intellectual Property (IP) cores (collectively referred to as “SoC devices” or simply “devices”) in a single electronic or semiconductor package. Each device in the platform has different processing capabilities suitable for handling a specific type of computational task. Examples of heterogenous processors include, but are not limited to: QUALCOMM's SNAPDRAGON, SAMSUNG's EXYNOS, APPLE's “A” SERIES, etc.
ITDM/OEM service(s) 102 may be provided on premises, along with one or more of managed IHSs 101A-N, or may be remotely located with respect to managed IHSs 101A-N. For example, one or more of managed IHSs 101A-N may be deployed within an enterprise, business, or corporation having an ITDM in charge of managing the usage, operation, servicing, configuration, and other aspects of IHSs 101A-N.
Particularly, an ITDM may use one or more management tools executed by ITDM service(s) 102 to establish management channel 104 with managed IHSs 101A-N. Examples of management tools may include, but are not limited to, WINDOWS Admin Center, MICROSOFT Endpoint Configuration Manager, System Center Configuration Manager (SCCM), AZURE, INTUNE, VMWARE WORKSPACE ONE, etc.
ITDM/OEM service(s) 102 may include an ITDM or OEM database. Such a database may include, for instance: an identification of managed IHSs 101A-N (e.g., by service tag, serial number, etc.), an inventory of IHS components installed in managed IHSs 101A-N (e.g., components integrated into managed IHSs 101A-N, peripheral devices coupled to managed IHSs 101A-N, etc.), an identification of a heterogenous computing platform 300 installed in managed IHSs 101A-N, a list of authorized users, usernames, passwords, logon credentials, cryptographic keys, digital certificates, Operating System (OS) installation or update packages, software application installation or update packages, firmware installation or update packages, hardware policies, software policies, telemetry collected from managed IHSs 101A-N, customer/client support information, etc.
In some cases, one or more management operations performed by ITDM/OEM service(s) 102 via management channel 104 may be selected or modified, at least in part, based upon information stored in the ITDM or OEM database. For example, a different firmware installation package containing a base driver and/or extension drivers (also referred to as information or “INF” drivers) may be selected, assembled, and/or delivered to each one of managed IHSs 101A-N, specifically for that IHSs' heterogenous computing platform.
The term “firmware,” as used herein, refers to a class of program instructions that provides low-level control for a device's hardware.

The term “firmware installation package,” as used herein, refers to program instructions that, upon execution, deploy device drivers or services in an IHS or IHS component.
The term “device driver” or “driver,” as used herein, refers to program instructions that operate or control a particular type of device. A driver provides a software interface to hardware devices, enabling an OS and other applications to access hardware functions without needing to know precise details about the hardware being used. When an application invokes a routine in a driver, the driver issues commands to a corresponding device. Once the device sends data back to the driver, the driver may invoke certain routines in the application. Generally, device drivers are hardware dependent and OS-specific.
Still referring to environment 100, any of managed IHSs 101A-N may be in communication with any other one of managed IHSs 101A-N and/or with another, third-party IHS 106, which is not necessarily managed by ITDM/OEM service(s) 102, over network(s) 103. Additionally, or alternatively, any of managed IHSs 101A-N may be in communication with third-party service(s) 105 (e.g., a cloud or remote service).
Examples of third-party service(s) 105 may include, but are not limited to, collaboration services (e.g., ZOOM, TEAMS, etc.), productivity services (e.g., MICROSOFT EXCHANGE servers, OFFICE 360, etc.), Artificial Intelligence (AI) services (e.g., AI as a Service or “AIaaS”), etc. In the case of AIaaS, orchestrator 501A (
As used herein, the terms “Artificial Intelligence” (AI) and “Machine Learning” (ML) are used interchangeably to refer to systems, computers, or machines that mimic human intelligence to perform tasks (and to iteratively improve themselves) based on the information they collect. Generally, AI is implemented through the execution, deployment, or serving of “AI models.”
The term “AI model,” as used herein, generally refers to a computer-executed algorithm that emulates logical decision-making based on data.

Generally, an AI model may be executed or deployed as a service. In some cases, a container system (e.g., DOCKER, KUBERNETES, etc.) may operate as a “box” for an AI model that creates reproducible, scalable, and isolated environments where users can set up dependencies so the AI model can work in any desired execution environment, such as, for example, a selected one of the plurality of devices in heterogenous computing platform 300 (
As depicted, IHS 200 includes host processor(s) 201. In various embodiments, IHS 200 may be a single-processor system, or a multi-processor system including two or more processors. Host processor(s) 201 may include any processor capable of executing program instructions, such as a PENTIUM processor, or any general-purpose or embedded processor implementing any of a variety of Instruction Set Architectures (ISAs), such as an ×86 or a Reduced Instruction Set Computer (RISC) ISA (e.g., POWERPC, ARM, SPARC, MIPS, etc.).
IHS 200 includes chipset 202 coupled to host processor(s) 201. Chipset 202 may provide host processor(s) 201 with access to several resources. In some cases, chipset 202 may utilize a QuickPath Interconnect (QPI) bus to communicate with host processor(s) 201.
Chipset 202 may also be coupled to communication interface(s) 205 to enable communications between IHS 200 and various wired and/or wireless networks, such as Ethernet, WiFi, BLUETOOTH (BT), cellular or mobile networks (e.g., Code-Division Multiple Access or “CDMA,” Time-Division Multiple Access or “TDMA,” Long-Term Evolution or “LTE,” etc.), satellite networks, or the like. Communication interface(s) 205 may also be used to communicate with certain peripherals devices (e.g., BT speakers, microphones, headsets, etc.). Moreover, communication interface(s) 205 may be coupled to chipset 202 via a Peripheral Component Interconnect Express (PCIe) bus, or the like.
Chipset 202 may be coupled to display/touch controller(s) 204, which may include one or more or Graphics Processor Units (GPUs) on a graphics bus, such as an Accelerated Graphics Port (AGP) or PCIe bus. As shown, display/touch controller(s) 204 provide video or display signals to one or more display device(s) 211.
Display device(s) 211 may include Liquid Crystal Display (LCD), Light Emitting Diode (LED), organic LED (OLED), or other thin film display technologies. Display device(s) 211 may include a plurality of pixels arranged in a matrix, configured to display visual information, such as text, two-dimensional images, video, three-dimensional images, etc. In some cases, display device(s) 211 may be provided as a single continuous display, or as two or more discrete displays.
Chipset 202 may provide host processor(s) 201 and/or display/touch controller(s) 204 with access to system memory 203. In various embodiments, system memory 203 may be implemented using any suitable memory technology, such as static RAM (SRAM), dynamic RAM (DRAM) or magnetic disks, or any nonvolatile/Flash-type memory, such as a solid-state drive (SSD) or the like.
Chipset 202 may also provide host processor(s) 201 with access to one or more Universal Serial Bus (USB) ports 208, to which one or more peripheral devices may be coupled (e.g., integrated or external webcams, microphones, speakers, etc.).
Chipset 202 may further provide host processor(s) 201 with access to one or more hard disk drives, solid-state drives, optical drives, or other removable-media drives 213.
Chipset 202 may also provide access to one or more user input devices 206, for example, using a super I/O controller or the like. Examples of user input devices 206 include, but are not limited to, microphone(s) 214A, camera(s) 214B, and keyboard/mouse 214N. Other user input devices 206 may include a touchpad, stylus or active pen, totem, etc.
Each of user input devices 206 may include a respective controller (e.g., a touchpad may have its own touchpad controller) that interfaces with chipset 202 through a wired or wireless connection (e.g., via communication interfaces(s) 205). In some cases, chipset 202 may also provide access to one or more user output devices (e.g., video projectors, paper printers, 3D printers, loudspeakers, audio headsets, Virtual/Augmented Reality (VR/AR) devices, etc.)
In certain embodiments, chipset 202 may further provide an interface for communications with hardware sensors 210.
Sensors 210 may be disposed on or within the chassis of IHS 200, or otherwise coupled to IHS 200, and may include, but are not limited to: electric, magnetic, radio, optical (e.g., camera, webcam, etc.), infrared, thermal (e.g., thermistors etc.), force, pressure, acoustic (e.g., microphone), ultrasonic, proximity, position, deformation, bending, direction, movement, velocity, rotation, gyroscope, Inertial Measurement Unit (IMU), and/or acceleration sensor(s).
Upon booting of IHS 200, host processor(s) 201 may utilize program instructions of Basic Input/Output System (BIOS) 207 to initialize and test hardware components coupled to IHS 200 and to load host OS 400 (
The Unified Extensible Firmware Interface (UEFI) was designed as a successor to BIOS. As a result, many modern IHSs utilize UEFI in addition to or instead of a BIOS. As used herein, BIOS 207 is intended to also encompass a UEFI component.
Embedded Controller (EC) or Baseboard Management Controller (BMC) 209 is operational from the very start of each IHS power reset and handles various tasks not ordinarily handled by host processor(s) 201. Examples of these operations may include, but are not limited to: receiving and processing signals from a keyboard or touchpad, as well as other buttons and switches (e.g., power button, laptop lid switch, etc.), receiving and processing thermal measurements (e.g., performing fan control, CPU and GPU throttling, and emergency shutdown), controlling indicator LEDs (e.g., caps lock, scroll lock, num lock, battery, ac, power, wireless LAN, sleep, etc.), managing PMU/BMU 212, alternating current (AC) adapter/Power Supply Unit (PSU) 215 and/or battery 216, allowing remote diagnostics and remediation over network(s) 103, etc.
For example, EC/BMC 209 may implement operations for interfacing with power adapter/PSU 215 in managing power for IHS 200. Such operations may be performed to determine the power status of IHS 200, such as whether IHS 200 is operating from AC adapter/PSU 215 and/or battery 216.
Firmware instructions utilized by EC/BMC 209 may also be used to provide various core operations of IHS 200, such as power management and management of certain modes of IHS 200 (e.g., turbo modes, maximum operating clock frequencies of certain components, etc.).
In addition, EC/BMC 209 may implement operations for detecting certain changes to the physical configuration or posture of IHS 200. For instance, when IHS 200 as a 2-in-1 laptop/tablet form factor, EC/BMC 209 may receive inputs from a lid position or hinge angle sensor 210, and it may use those inputs to determine: whether the two sides of IHS 200 have been latched together to a closed position or a tablet position, the magnitude of a hinge or lid angle, etc. In response to these changes, the EC may enable or disable certain features of IHS 200 (e.g., front or rear facing camera, etc.).
In some cases, EC/BMC 209 may be configured to identify any number of IHS postures, including, but not limited to: laptop, stand, tablet, tent, or book. For example, when display(s) 211 of IHS 200 is open with respect to a horizontal keyboard portion, and the keyboard is facing up, EC/BMC 209 may determine IHS 200 to be in a laptop posture. When display(s) 211 of IHS 200 is open with respect to the horizontal keyboard portion, but the keyboard is facing down (e.g., its keys are against the top surface of a table), EC/BMC 209 may determine IHS 200 to be in a stand posture.
When the back of display(s) 211 is closed against the back of the keyboard portion, EC/BMC 209 may determine IHS 200 to be in a tablet posture. When IHS 200 has two display(s) 211 open side-by-side, EC/BMC 209 may determine IHS 200 to be in a book posture. When IHS 200 has two displays open to form a triangular structure sitting on a horizontal surface, such that a hinge between the displays is at the top vertex of the triangle, EC/BMC 209 may determine IHS 200 to be in a tent posture. In some implementations, EC/BMC 209 may also determine if display(s) 211 of IHS 200 are in a landscape or portrait orientation.
In some cases, EC/BMC 209 may be installed as a Trusted Execution Environment (TEE) component to the motherboard of IHS 200.
Additionally, or alternatively, EC/BMC 209 may be configured to calculate hashes or signatures that uniquely identify individual components of IHS 200. In such scenarios, EC/BMC 209 may calculate a hash value based on the configuration of a hardware and/or software component coupled to IHS 200. For instance, EC/BMC 209 may calculate a hash value based on all firmware and other code or settings stored in an onboard memory of a hardware component.
Hash values may be calculated as part of a trusted process of manufacturing IHS 200 and may be maintained in secure storage as a reference signature. EC/BMC 209 may later recalculate the hash value for a component may compare it against the reference hash value to determine if any modifications have been made to the component, thus indicating that the component has been compromised. In this manner, EC/BMC 209 may validate the integrity of hardware and software components installed in IHS 200.
In various embodiments, IHS 200 may be coupled to an external power source (e.g., AC outlet or mains) through an AC adapter/PSU 215. AC adapter/PSU 215 may include an adapter portion having a central unit (e.g., a power brick, wall charger, or the like) configured to draw power from an AC outlet via a first electrical cord, convert the AC power to direct current (DC) power, and provide DC power to IHS 200 via a second electrical cord.
Additionally, or alternatively, AC adapter/PSU 215 may include an internal or external power supply portion (e.g., a switching power supply, etc.) connected to the second electrical cord and configured to convert AC to DC. AC adapter/PSU 215 may also supply a standby voltage, so that most of IHS 200 can be powered off after preparing for hibernation or shutdown, and powered back on by an event (e.g., remotely via wake-on-LAN, etc.). In general, AC adapter/PSU 215 may have any specific power rating, measured in volts or watts, and any suitable connectors.
IHS 200 may also include internal or external battery 216. Battery 216 may include, for example, a Lithium-ion or Li-ion rechargeable device capable of storing energy sufficient to power IHS 200 for an amount of time, depending upon the IHS's workloads, environmental conditions, etc. In some cases, a battery pack may also contain temperature sensors, voltage regulator circuits, voltage taps, and/or charge-state monitors.
Power Management Unit (PMU) 212 governs power functions of IHS 200, including AC adapter/PSU 215 and battery 216. For example, PMU 212 may be configured to: monitor power connections and battery charges, charging batteries, control power to other components, devices, or ICs, shut down components when they are left idle, control sleep and power functions (On and Off), managing interfaces for built-in keypad and touchpads, regulate real-time clocks (RTCs), etc.
In some implementations, PMU 212 may include one or more Power Management Integrated Circuits (PMICs) configured to control the flow and direction or electrical power in IHS 200. Particularly, a PMIC may be configured to perform battery management, power source selection, voltage regulation, voltage supervision, undervoltage protection, power sequencing, and/or charging operations. It may also include a DC-to-DC converter to allow dynamic voltage scaling, or the like.
Additionally, or alternatively, PMU 212 may include a Battery Management Unit (BMU) (referred to collectively as “PMU/BMU 212”). AC adapter/PSU 215 may be removably coupled to a battery charge controller within PMU/BMU 212 to provide IHS 200 with a source of DC power from battery cells within battery 216 (e.g., a lithium ion (Li-ion) or nickel metal hydride (NiMH) battery pack including one or more rechargeable batteries). PMU/BMU 212 may include non-volatile memory and it may be configured to collect and store battery status, charging, and discharging information, and to provide that information to other IHS components, such as, for example devices within heterogeneous computing platform 300 (
Examples of information collected and stored in a memory within PMU/BMU 212 may include, but are not limited to: operating conditions (e.g., battery operating conditions including battery state information such as battery current amplitude and/or current direction, battery voltage, battery charge cycles, battery state of charge, battery state of health, battery temperature, battery usage data such as charging and discharging data; and/or IHS operating conditions such as processor operating speed data, system power management and cooling system settings, state of “system present” pin signal), environmental or contextual information (e.g., such as ambient temperature, relative humidity, system geolocation measured by GPS or triangulation, time and date, etc.), and BMU events.
Examples of BMU events may include, but are not limited to: acceleration or shock events, system transportation events, exposure to elevated temperature for extended time periods, high discharge current rate, combinations of battery voltage, battery current and/or battery temperature (e.g., elevated temperature event at full charge and/or high voltage causes more battery degradation than lower voltage), etc.
In some embodiments, power draw measurements may be conducted with control and monitoring of power supply via PMU/BMU 212. Power draw data may also be monitored with respect to individual components or devices of IHS 200. Whenever applicable, PMU/BMU 212 may administer the execution of a power policy, or the like.
IHS 200 may also include one or more fans 217 configured to cool down one or more components or devices of IHS 200 disposed inside a chassis, case, or housing. Fan(s) 217 may include any fan inside, or attached to, IHS 200 and used for active cooling. Fan(s) 217 may be used to draw cooler air into the case from the outside, expel warm air from inside, and/or move air across a heat sink to cool a particular IHS component. In various embodiments, both axial and sometimes centrifugal (blower/squirrel-cage) fans may be used.
In other embodiments, IHS 200 may not include all the components shown in
For example, in various embodiments described herein, host processor(s) 201 and/or other components of IHS 200 (e.g., chipset 202, display/touch controller(s) 204, communication interface(s) 205, EC/BMC 209, etc.) may be replaced by discrete devices within heterogenous computing platform 300 (
In various implementations, each device in platform 300 may include its own microcontroller(s) or core(s) (e.g., ARM core(s)) and corresponding firmware. In some cases, a device in platform 300 may also include its own hardware-embedded accelerator (e.g., a secondary or co-processing core coupled to a main core).
Each device in platform 300 may be accessible through a respective Application Programming Interface (API). Additionally, or alternatively, each device in platform 300 may execute its own OS. Additionally, or alternatively, one or more of devices in platform 300 may be a virtual device.
In certain embodiments, at least one device in platform 300 may have updatable firmware which, upon installation, operates to change the performance, available features, settings, configuration options, API, drivers, and/or services provided by that device. For example, each update may be delivered to platform 300 as a system-wide firmware installation package having a plurality of firmware components, and each firmware component may be distributed to its respective device (or corresponding memory space).
In some implementations, the latest system-wide firmware installation package received by platform 300 may be installed at every boot of IHS 200.
In the example of
CPU clusters 301A-N are coupled to memory controller 302 via main bus or interconnect 303. Memory controller 302 is responsible for managing memory accesses for all of devices connected to interconnect 303, which may include any communication bus suitable for inter-device communications within an SoC (e.g., Advanced Microcontroller Bus Architecture or “AMBA,” QPI, HyperTransport or “HT,” etc.). All devices coupled to interconnect 303 can communicate with each other and with a host OS executed by CPU clusters 301A-N through interconnect 303.
GPU 304 is a device designed to produce graphical or visual content and to communicate that content to a monitor or display, where the content may be rendered.
PCIe controller or root complex 305 provides an entry point into any additional devices external to platform 300 that have a respective PCIe interface (e.g., graphics cards, USB controllers, etc.).
Audio Digital Signal Processor (aDSP) 306 is a device designed to perform audio and speech operations and to perform in-line enhancements for audio input(s) and output(s). Examples of audio and speech operations include, but are not limited to: noise reduction, echo cancellation, directional audio detection, wake word detection, muting and volume controls, filters and effects, etc.
In operation, input and/or output audio streams may pass through and be processed by aDSP 306, which can send the processed audio to other devices on interconnect 303 (e.g., CPU clusters 301A-N). aDSP 306 may also be configured to process one or more of platform 300's sensor signals (e.g., gyroscope, accelerometer, pressure, temperature, etc.), low-power vision or camera streams (e.g., for user presence detection, onlooker detection, etc.), or battery data (e.g., to calculate a charge or discharge rate, current charge level, etc.). To that end, aDSP 306 may be coupled to BMU 212.
In some cases, aDSP 306 may execute a firmware service configured to: retrieve raw battery data from PMU/BMU 212, preprocess the raw data, and prepare features or attributes (e.g., select, reduce, concatenate, group, etc.) for subsequent processing. Furthermore, to change a PMU/BMU 212 setting, aDSP 306 may communicate with EC/BMC 209 and/or PMU/BMU 212 to request a change to that setting. Examples of PMU/BMU 212 settings may include, but are not limited to: a charge rate ‘C’ (e.g., 0.5 C for slow charges, 0.3 C for trickle charging, 2.5 C for fast charging, etc.), a sustained or average peak power (SPP) parameter, a maximum peak power (MPP) parameter, a maximum charge current (MCC) parameter, etc.
Sensor hub and low-power AI device 307 is a very low power, always-on device designed to consolidate information received from other devices in platform 300, process any context and/or telemetry data streams, and provide that information to: (i) host OS 400, (ii) applications 412-414, and/or (iii) other devices in platform 300. For example, sensor hub and low-power AI device 307 may include general-purpose input/output (GPIOs) that provide Inter-Integrated Circuit (I2C), Serial Peripheral Interface (SPI), and/or serial interfaces to receive data from sensors (e.g., sensors 210, camera 310, peripherals 314, etc.).
As used herein, the terms “context data” or “contextual data” refer broadly to any relevant, background information that can provide a broader understanding of an entity or event. Generally, context data may come from various sources, and it may be used to provide insights into an IHS's operation and/or of a user's behavior patterns, thereby improving their experience.
For instance, examples of context data accessible by orchestrator 501A (
In some cases, context data may be used to identify presence hint(s) and/or user engagement cue(s). As used herein, the term “presence hints” refers to any information usable to characterize whether a user is present or absent before IHS 200 and/or a distance between the user of IHS 200. For example, presence hints may include (or be derived from) data received from presence or proximity sensors 210, camera 310, peripheral devices 314 (e.g., whether the user is typing at a keyboard or moving a mouse), etc.
The term “user engagement cue” refers to any user's action, such as utterances, movements, stances, gestures (e.g., fingers, hand, arm, head, body, etc.), or other behavior indicative of whether and/or to what degree a user is engaged with aspects of IHS 200 and/or applications 412-414. In various implementations, to identify a user engagement cue, one or more devices in heterogenous computing platform 300 may be configured to perform speech and/or gesture recognition operations based on audio and/or video data streams captured with microphone(s) 214A and/or camera(s) 214B. Moreover, to determine a level of engagement of a user, orchestrator 501A may keep track of one or more engagement cues and calculate an engagement score based upon the number, frequency of occurrence, and/or weight of the detected cue(s).
The term “telemetry data,” as used herein, refers to information resulting from in situ collection of measurements or other data by devices 301-315, or any other IHS device or component, and its transmission (e.g., automatically) to a receiving entity, such as orchestrator 501A (
For instance, telemetry data may include, but is not limited to, measurements, metrics, logs, or other information related to: current or average utilization of devices 301-315 or other IHS components, CPU/core loads, instant or average power consumption of devices 301-315 or other IHS components, instant or average memory usage by devices 301-315 or other IHS components, characteristics of a network or radio system (e.g., WiFi vs. 5G, bandwidth, latency, errors, etc.), keyboard, mice, trackpad, or trackball usage data, transaction times, latencies, response codes, errors, data collected from sensors 210, etc.
It should be noted that, in some implementations, there may be overlap between context data and telemetry data and/or sources. In other implementations, however, context data and telemetry data and/or sources may be distinct from each other.

In various implementations, fan controller 315 may be used to operate fan(s) 217. For example, fan controller 315 may be provided to regulate the speed of the fan(s) 217.
Fan controller 315 may receive periodic sensor readings from one or more sensors of the chassis 104 and dynamically adjust the speed of fan(s) 217 using a proportional-integral-derivative (PID) controller algorithm that is fed with sensor data such as, for example: outlet ambient temperature, CPU temperature, Dual In-line Memory Module or “DIMM” temperature, IHS power consumption, etc.
In case of sensor or fan controller failure, fan(s) 217 may be configured to operate at their maximum speed. Additionally, or alternatively, EC/BMC 209 or other platform device (e.g., sensor hub and low-power AI device 307) may send control signals to fan controller 315 to operate fan(s) 217.

Applications 412-414 (and/or host OS 400 components) may use AI models executed by devices within platform 300 for various reasons, ranging from video/audio processing to system optimization tasks. Additionally, or alternatively, ITDMs/OEMs may direct a selected device within platform 300 to act as orchestrator 501A (

Core OS/API service 404 has direct access to processing component(s) of IHS 200 such as, for example, heterogenous computing platform 300. OS drivers 405 include kernel mode drivers developed by the OS publisher or other developer. Platform drivers 406 include kernel mode drivers developed by the manufacturer of heterogenous computing platform 300, for example, for use with devices 301-315.
In user space 402, user-mode platform drivers and services 407 enable access to features provided by devices 301-315 through kernel-mode platform drivers 406.

Moreover, other application(s) 414 may include or be a part of any workload executable by heterogenous computing platform 300. For example, other application(s) 414 may include productivity, collaboration, streaming, multimedia, or gaming applications executable by host OS 400.
Optimization/customization application(s) 412 may include any host OS 400-level application configured to intelligently optimize the performance of IHS 200 (e.g., DELL OPTIMIZER), for example, by using AI models to dynamically configure IHS 200's settings and/or to optimize the performance of other applications 414. In operation, optimization/customization application(s) 412 may improve the productivity, performance, and user experience through system usage analysis and learning. For example, optimization/customization application(s) 412 may be invoked, within host OS 400, to learn how a selected application 414 is used. Optimization/customization application(s) 412 may identify optimization opportunities, classify users, and automatically apply appropriate settings (e.g., storage, memory, and/or CPU) to improve a selected application 414's performance.
At least one of applications 412-414 may be configured to utilize one or more devices, features, or services exposed, surfaced, enumerated, or otherwise made available by user-mode drivers 407-409, for example, through a Human Interface Device (HID) interface and/or an HID report provided by host OS 400, or the like. In some cases, one or more of applications 412-414 may operate as orchestrator 501A (
In various implementations, host OS 400 may be configured to receive a firmware installation package or executable file containing at least one extension driver (e.g., a setup information or “INF” text file in a driver package) from ITDM/OEM service(s) 102 via management channel 104. The installation package may be processed by a UEFI UpdateCapsule process when distributed as part of an OS update, as a system-wide and/or device-specific firmware update, and/or it may be distributed by OEM update applications such as DELL COMMAND UPDATE, integrated with remote deployment and update management tools.
Firmware components of each extension driver may be loaded, attached, or extended onto user-mode platform drivers and services 407, and may be communicated by user-mode platform drivers and services 407 to respective devices of heterogenous computing platform 300 through kernel-mode platform drivers 406 for installation, update, or execution of such firmware components in those devices.
As such, the deployment of extension drivers by host OS 400 as OEM drivers 408 provides value-added features or services to user-mode platform drivers (e.g., base drivers) 407 and/or applications 412-414. Particularly, OEM drivers 408 may expose custom services and routines provided by any one of devices 301-315 upon execution of their corresponding firmware components. In some cases, OEM driver 408 may also operate as orchestrator 501A (
Each of APIs 502A-N provides access to firmware 503A-N executed by a corresponding device 501A-N. In operation, each firmware component 503A-N may exchange data and commands directly with each other using APIs 502A-N. Through APIs 502A-N, one or more of devices 501A-N may be configured to enable, disable, or modify firmware services provided by other devices 503A-N. For example, in some embodiments, one or more of devices 501A-N may be designated as orchestrator 501A (
In various embodiments, firmware services resulting from the execution of firmware 503A-N may be provided by their respective device 501A-N to other devices 501A-N within heterogeneous computing platform 300 autonomously and/or independently of the operation of host OS 400. Communications between executing firmware 503A-N and applications 412-414 may take place through OEM drivers 408. In some cases, executing firmware 503A-N may be identified by or exposed to host OS 400 and/or applications 412-414 as part of HID reports.
Firmware services 601A-N and corresponding OEM drivers 408 may be installed, modified, updated, and/or removed from IHS 200 upon each installation of a firmware installation package for the entire heterogenous computing platform 300, for example, at each boot of IHS 200. For example, each firmware component 503A-N providing a respective firmware service 601A-N may be delivered to a respective device 501A-N as an extension driver. Upon execution, firmware services 601A-N may provide additional controls over the management, deployment, customization, and/or configuration of IHS 200 to the ITDM or OEM that are independent of updates to host OS 400 and/or applications 412-414.
In other embodiments, any given one of devices 501A-N may be rebooted or reset independently of the other devices to perform a local installation, update, or modification of that given device's firmware services 601A-N without having to reboot the entire heterogenous computing platform 300 and/or IHS 200. Additionally, or alternatively, one or more of devices 501A-N may have its firmware service 601A-N at least partially installed or updated without rebooting or resetting the device.
Orchestrator 501A may be configured to provide firmware service(s) 601A through the execution of firmware 503A. Similarly, each of devices 501B-N may be configured to provide their own firmware service(s) 601B-N through the execution of firmware 503B-N. Moreover, each of firmware services 601A-N may operate independently of host OS 400.
Firmware service(s) 601A of orchestrator 501A may be configured to facilitate the communication of data, commands, AI models, scripts, and/or routines among firmware services 601B-N of devices 601B-N via APIs 502B-N. Additionally, or alternatively, firmware services 601B-N may exchange data and commands with each other using APIs 502B-N.
For example, in some cases orchestrator 501A may be implemented by sensor hub and low-power AI device 307 and/or by EC/BMC 209. GPU 304 may execute firmware service 601B, high-performance AI device 308 may execute firmware service 601C, aDSP 306 may execute firmware service 601D, display 309 may execute firmware service 601E, and other devices 501F-N (e.g., modem 313, peripherals 314, etc.) may execute respective ones of firmware services 601F-N. Firmware services 601A-N may be performed through the execution of firmware components 503A-N previously distributed as extension drivers in a heterogenous computing platform 300-wide firmware installation package.
Orchestrator 501A may be configured to operate a plurality of devices 501B-N and to receive context/telemetry data therefrom. In this manner, orchestrator 501A may be configured to enable IHS users, ITDMs, and/or OEMs to manage, deploy, customize, and/or configure IHS 200 and/or applications 412-414, for example, based upon contextual or telemetry-based rules.
In various embodiments, systems and methods described herein may enable an ITDM or OEM to manage, deploy, customize, and/or configure aspects of IHS 200 through orchestrator 501A. For example, ITDM/OEM service(s) 102 may provide one or more devices 501A-N of heterogeneous computing platform 300 with firmware components 503A-N that, upon execution by their respective devices, add, remove, or modify services accessible to one or more application(s) 412-414 based upon context/telemetry data.
Particularly, orchestrator 501A may receive message(s), file(s), command(s), script(s), and/or ITDM/OEM management polic(ies) 602 (e.g., an Extensible Markup Language or “XML”, a JavaScript Object Notation or “JSON” file, etc.) from ITDM/OEM service(s) 102 via OS agent(s) 413 (i.e., in-band).
When management channel 104 is an OOB channel between EC/BMC 209 and ITDM/OEM service(s) 102, OS agent(s) 413 may be replaced with EC/BMC 209.
In some cases, along with polic(ies) 602, OS agent(s) 413 may also receive one or more AI models and/or AI model parameters for use by a device within platform 300, such as high-performance AI device 308 and/or sensor hub and low-power AI device 307. AI models and/or parameters may be provided to OS agent(s) 413 by ITDM/OEM service(s) 102 or by third-party service(s) 105.
Polic(ies) 602 may contain commands, program instructions, routines, and/or rules that conform to APIs 502A-N. Alternatively, or alternatively, orchestrator 501A may interpret polic(ies) 602 and issue commands conforming to APIs 502A-N. Using APIs 502B-N, orchestrator 501A may be configured to enable, disable, or modify firmware services 601B-N based upon instructions conveyed in polic(ies) 602 (e.g., in response to changes in context, telemetry, etc.) without the involvement of host OS 400.
For example, based upon polic(ies) 602, orchestrator 501A may install, update, modify, enable or disable any of firmware services 601A-N in each of devices 501A-N in response to the detection of one or more of: an IHS location, an IHS posture (e.g., lid closed, etc.), an IHS identification (e.g., service tag, serial number, etc.), a type of IHS (e.g., manufacturer, model, etc.), an identification or type of heterogenous computing platform 300, an IHS battery (dis)charge level or rate, an identity or type of connected or available IHS peripherals, a security posture of IHS 200 (e.g., connected to VPN, disposed in a trusted or secure location, etc.), an identity or type of applications 412-414 executed by host OS 400, an identity or type of one of applications 412-414 requesting firmware services 601A-N (e.g., via OEM driver 408), an identification of a user of the IHS, an identification of a user group or role, a user's proximity to the IHS, a user's level of user engagement, detected onlooker(s), a user's personal information (e.g., languages spoken, video or audio preferences, etc.), calendar events or data (e.g., type, time, and duration of a collaboration session, priority or importance of the session, role of the user in the session, recurring status, identities and roles of other participants in the session, etc.), messaging (e.g., email, text messages, etc.) data (e.g., subject, date sent and received, number of related messages, priority, names and roles of addressees, etc.), environmental conditions (e.g., weather, background noise levels, lighting level or quality, etc.), etc.
In some cases, polic(ies) 602 may specify that orchestrator 501A select one or more of a plurality of different AI models (or different instances of the same AI model) to be used for a given operation in response to the IHS being at a certain geographic location, network location, type of audio environment, etc. Any of the contextual and/or telemetry information described herein may be used to create different sets of conditions for rules outlined in polic(ies) 602.
For example, polic(ies) 602 may specify that high-performance AI device 308 be used to apply a more computationally costly AI model (or a larger number of models) under a favorable set of conditions (e.g., if battery level is above a first threshold level, if IHS 200 is connected to AC power, if a certain application or type of application is in execution, if a level of utilization of high-performance AI device 308 and/or sensor hub and low-power AI device 307 is below a threshold level, etc.). Under a set of less favorable conditions (e.g., if battery level is below a second threshold level, if a certain application or type of application is not in execution, if a level of utilization of high-performance AI device 308 is above a threshold level, etc.), however, polic(ies) 602 may specify that sensor hub and low-power AI device 307 be used to apply a less computationally costly AI model (or fewer models).
In some cases, polic(ies) 602 may also determine whether or under what conditions the user many manually override its rules and settings (e.g., turn a camera or microphone on or off, enable or disable a filter or effect, etc.). Moreover, for different types of users (e.g., engineer, customer support, executive, etc.) who tend to interact with their IHSs 101A-N in different ways, ITDM/OEM service(s) 102 may deploy different rules, AI models, and/or parameters by selecting and deploying different polic(ies) 602.
In many scenarios, systems and methods described herein may enable the collection and management of context/telemetry data from one or more of devices 501A-N, host OS 400, and/or applications 412-414. In that regard,
At 701, orchestrator 501A may receive polic(ies) 602. Polic(ies) 602 may be selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N, service tags, network addresses, user IDs, etc.) and may include rules and/or parameters usable by orchestrator 501A to manage context/telemetry data collection operations autonomously and/or independently of host OS 400. For example, polic(ies) 602 may identify one or more of: context/telemetry data to be collected, devices to collect the context/telemetry data from, context/telemetry data collection parameters (e.g., collection frequency or sampling rate, collection start and end times, a duration of the collection, a maximum amount of telemetry data to be collected, etc.), context/telemetry data collection routines, scripts, and algorithms to process and/or produce the context/telemetry data, etc. In some cases, each individual piece or set of context/telemetry data may include a common clock time stamp (e.g., if requested by polic(ies) 602).
At 702, orchestrator 501A may select one or more devices (e.g., among devices 301-315 of heterogeneous computing platform 300) to collect context/telemetry data from, based upon polic(ies) 602. In some cases, selected devices may be dynamically chosen by orchestrator 501A based upon previously collected context/telemetry data, as also outlined in polic(ies) 602.
At 703, firmware service(s) 601A of orchestrator 501A may send message(s) to one or more of firmware services 601B-N of selected devices 501A-B with instructions about how to collect any identified context/telemetry data and/or how to deliver the collected context/telemetry data. For example, such message(s) may inform a given context/telemetry collection device which other device(s) to deliver the collected data to, acceptable data format(s) or protocol(s), the manner and/or frequency of data delivery, etc. Moreover, these message(s) may be transmitted between firmware services(s) 601A-N without any involvement by host OS 400.
Firmware service(s) 601A may transmit context/telemetry collection messages to any given one of firmware service(s) 601B-N executed by devices 501B-N using a respective one of APIs 502A-N. Conversely, firmware service(s) 601B-N of devices 501B-N may send messages (e.g., acknowledgement, device status, context/telemetry data collected, etc.) to firmware service(s) 601A orchestrator 501A using API 502A, again without any involvement by host OS 400. Then, at 704, firmware service(s) 601A of orchestrator 501A receives context/telemetry data from the selected devices 501B-N following API 502A.
In various implementations, the collected context/telemetry data may be used by orchestrator 501A to enforce a wide variety of management decisions based upon polic(ies) 602. Additionally, or alternatively, the collected context/telemetry data may be input into AI model(s) executed by device(s) 501A-N.
In some cases, method 700 may be performed at the request of applications 412-414. By maintaining all context/telemetry collection routines in firmware 503A-N, method 700 addresses concerns associated with the excessive consumption of IHS resources by OS-level telemetry collection software. When orchestrator 501A serves as the only point of contact for all context/telemetry requests targeting devices 501A-N, it may output a stream of context/telemetry data to host OS 400.
At 801, orchestrator 501A may receive polic(ies) 602 selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N). At 802, orchestrator 501A may initiate and/or manage context/telemetry data collection operations autonomously and/or independently of host OS 400, as shown in method 700 (
At 803, orchestrator 501A uses at least a subset of context/telemetry information—and/or it uses AI mode inferences produced based upon the subset of context/telemetry information—to enforce the execution of AI models following rules indicated ITDM/OEM polic(ies) 602. In that regard, it should be noted that an ITDM/OEM may set use polic(ies) 602 to enforce unique rules, triggers, and/or thresholds for selecting AI processing settings for different ones of IHSs 101A-N (or groups of IHSs) with different levels of granularity, based on context/telemetry data.
For example, at 803, orchestrator 501A may enforce a policy rule which dictates that a particular device within heterogeneous computing platform 300 be selected to execute a specific AI model (or type of AI model) with certain parameter(s) in response to different context/telemetry data, such as, for example: when an IHS is on battery power (or when the battery charge drops below or rises above a minimum value), when the IHS 200 is in a certain location (e.g., at work, at home, within a distance from selected coordinates, etc.), based on hardware utilization (e.g., a level of utilization of one or more of the devices in platform 300 reaches a maximum or minimum value), if the user of IHS 200 belongs to a selected group of users (e.g., “managers,” “engineers,” etc.), when IHS 200 is manipulated into a given posture, when the user is present or within a selected distance from IHS 200, etc.
At 804, orchestrator 501A may determine if there are any context/telemetry data changes (e.g., if the latest data has a value different than a previously collected data value by an amount greater than or equal to a threshold value). If not, control stays with 804. If so, control returns to 803, where orchestrator 501A may select different device(s), AI model(s), and/or parameter(s) to initiate new AI processes or give continuance to ongoing AI processes (e.g., AI model migration).
As such, method 800 provides a mechanism for orchestrator 501A to dynamically modify the provisioning of AI services by heterogeneous computing platform 300 autonomously and/or independently of host OS 400.
In various embodiments, systems and methods described herein may employ various aspects of heterogeneous computing platform 300 to manage thermal, power, performance, and acoustic characteristics of IHS 200. For example, these systems and methods may be used to implement passive and active cooling techniques with a focus context, telemetry, and usage priorities (e.g., gaming, performance, etc.).
In that regard,
Ordinarily, IHS 200 may be configured to monitor the temperature value provided by a temperature or electrical current sensor 903A-N in each thermal zone 902A-N and to: (a) apply one or more thermal mitigation actions to heat-producing components 910A-N (e.g., host processor(s) 201, GPU 204, PSU 215, heterogeneous computing platform 300, etc.) within its respective zone(s), such as, for example, by modifying a component's performance (e.g., its frequency or speed of operation), and/or (b) adjust the operation of an active cooling system, such as fan(s) 217.
In general, any number of thermal zones 902A-N may be defined within IHS 200, and each zone 902A-N may include any number of components 901A-N, as well as its own sensor 903A-N. In some cases, two or more components (e.g., 901B and 901N) may be part of the same thermal zone (e.g., 902N). Additionally, or alternatively, a single component (e.g., 901A) may be included in two or more thermal zones (e.g., thermal zones 902A and 902B) at the same time.
In some implementations, at least one thermal zone is defined to implement a critical shutdown temperature (and hibernate temperature, if supported). Additionally, or alternatively, thermal zones may be defined to monitor specific devices or skin temperature for mitigation.
Device drivers 1001A-N include kernel mode drivers that provide a thermal cooling interface configured to implement, in each respective IHS component 901A-N (
Thermal manager 1005 within kernel power manager 1006 may orchestrate cooling efforts in IHS 200 by interpreting thermal zone definition 1002 and invoking the proper interfaces at the required times. In some implementations, thermal manager 1005 may be part of the host OS 400's kernel.
In operation, thermal zone is described in firmware and exposed to thermal manager 1005 through ACPI. In this manner, thermal manager 1005 may determine how many thermal zones need to be managed, when to start throttling each thermal zone, and/or which IHS components are a part of each thermal zone.
When thermal manager 1005 is notified of a thermal event by temperature sensor driver 1004 of thermal zone 1002, for example, it may start to periodically evaluate the temperature of that zone, and it may determine a thermal throttling performance percentage to apply to one or more IHS components therein. In some cases, such an evaluation may use thermal throttling algorithms outlined in the ACPI specification.
Thermal manager 1005 may then notify all device drivers 1001A-N in zone 1002 to throttle performance by a specific percentage, and device drivers 1001A-N may translate the throttling hint to a device-class-specific action to reduce the IHS component's performance; that is, each device driver registered as a thermal throttling device receives a thermal throttling percentage request and translates that percentage to an action that makes sense for itself. Such periodic evaluation and throttling may be stopped when temperature sensor driver 1004 reports a temperature below the throttling threshold temperature, and throttling is no longer required.
In some cases, device drivers 1001A-N may be configured to map the provided thermal limit to its specific cooling IHS component characteristics and to implement appropriate cooling mitigations. If a same IHS component appears in multiple thermal zones, the thermal limit that constrains the IHS component the most (that is, the lowest percentage) may be passed to its corresponding device driver.
For example, when a device driver 1001A-N is for a processing core (e.g., in host processor 201 or any device 301-315 equipped with its own processing cores), thermal manager 1005 may communicate the thermal throttling percentage to a Processor Power Manager (PPM) within host OS 400, which allows core parking and processor idling as additional thermal mitigation possibilities.
For display backlight control, thermal manager 1005 may communicate the thermal throttling percentage to the monitor driver (e.g., monitor.sys), which in turn decides the actual backlight level setting based upon this thermal input.
With respect to battery charging, yet another device driver (e.g., cmbatt.sys) may take the current thermal limit into account during charging operations.
Similarly, a network driver may receive the thermal hints from thermal manager 1005 and apply its own performance reduction strategies to reduce the heat produced by network cards and wireless adaptors.
Thermal zone 1105 may receive the notification, and it may compare a temperature reading included in the notification to an active trip point associated with zone 1105 to determine whether fan(s) 217 should be on, off, and/or at a particular speed.
In response, thermal zone 1105 may send a command to fan device 1106 (e.g., one of device drivers 1001A-N), which in turn applies fan settings to fan hardware 1103 (e.g., fan controller 315), thus effectively controlling the speed of fan(s) 217.
In some cases, once fan(s) 217 are turned on, another IHS component such as EC/BMC 209, for example, may take over their operation using its own algorithm.
As used herein, the term “sustained power limit or level” or “maximum sustained power limit or level” generally refer to the largest amount of electrical power that a device is allowed to consume and/or dissipate over a long duration (i.e., as opposed to power consumed instantly, or burst over a short period). In contrast, the terms “burst power limit or level” or “maximum burst power limit or level” relate to a device's ability to consume and/or dissipate power bursts of short duration (often orders of magnitude shorter than sustained periods).
On an “×86” platform, the IHS's “sustained power limit” may be referred to as “PL1” and its “burst power limit” may be referred to as “PL2.”
A typical maximum burst limit or threshold level is usually greater than a device's maximum sustained power limit or threshold level. For example, the specified maximum sustained power limit or threshold level may be approximately 6.0 W continuous, while the specified maximum burst power limit or threshold level may be approximately 9.0 W. Nevertheless, it should be appreciated that the maximum sustained and burst power limits or threshold levels may be unique to each of devices 501A-N.
In a hypothetical situation, a user may operate IHS 200 on their lap, for example, while sitting on a chair. In another situation, the user may place IHS 200 atop a desk or table. In yet another situation, during operation of IHS 200, the user may convert it from a laptop posture to a tablet posture, or any other IHS posture. Yet, conventional heterogeneous computing platforms have no concept of updating thermal zones in IHS 200 and/or platform 300 based upon the IHS's posture or movement.
To address these, and other issues, systems and methods described herein may enable sustained power limit control in heterogenous computing platforms. These systems and methods may include a software service set running on firmware configured to switch ACPI thermal zone settings dynamically when the IHS's posture is changed, based upon an ITDM/OEM policy and/or context/telemetry data.
In some cases, a firmware service running in EC/BMC 209 or similar hardware controller may be configured to receive IHS posture information (e.g., current IHS posture, hinge angle, etc.) from EC/BMC 209, and to select and implement thermal zone settings in platform 300 and/or IHS 200 that set target performance modes for various sub-system components.
In that regard,
For example, method 1200 may be performed, at least in part, by EC/BMC 209 or sensor hub and low-power AI device 307. In some cases, method 1200 may be configured to collectively address multiple IHS posture changes or events as they occur.
At 1201, firmware service(s) 601A executed by orchestrator 501A may receive polic(ies) 602 selected by ITDM/OEM service 102 (e.g., based upon the identities of IHSs 101A-N). Based upon rules within polic(ies) 602, orchestrator 501A may identify context/telemetry information to collect from a subset of other devices within heterogeneous computing platform 300 and/or host OS 400. As such, at 1202, method 1200 may also include receiving context/telemetry data, for example, as described in method 700 (
The context/telemetry data may include a metric indicative of at least one of: a core utilization, a memory utilization, a network utilization, a battery utilization, a peripheral device utilization, a user's presence or proximity, a user's level of engagement, an IHS location, an application or type of application in execution, calendar data (e.g., day, time, and duration of collaboration or gaming sessions), a battery's SOC, whether IHS 200 is plugged into an AC outlet (or another type of input power source, such as an external battery pack or solar panel), etc.
At 1203, orchestrator 501A may determine whether a particular IHS posture has been selected by a user of IHS 200. For example, orchestrator 501A may receive a message from EC/BMC 209 with an indication of a currently selected IHS posture, state, hinge angle, etc.
In some cases, each IHS posture may be associated, via polic(ies) 602, with a set of one or more APCI thermal zones, and each thermal zone may include its own unique settings or parameters (e.g., a selected number of devices, the devices themselves, trip point(s), mitigation action(s), temperature sensor(s), etc.). Moreover, each thermal zone setting may be associated with context/telemetry data such that, in different contexts or telemetry scenarios, different thermal zone settings may be chosen for the same IHS posture. In various embodiments, any of the contextual/telemetry data discussed herein may be used to select different thermal zone settings.
If an IHS posture change is detected, at 1204, orchestrator 501 may modify one or more thermal zone settings based upon the detection. Otherwise, control returns to 1202 to perform continuous, periodic, or event-driven IHS posture monitoring and/or reporting operation(s).

These program instructions may also be stored in a computer readable storage medium that can direct a computer system, other programmable data processing apparatus, controller, or other device to operate in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the operations specified in the block diagram block or blocks.

Modules implemented in software for execution by various types of processors may, for instance, include one or more physical or logical blocks of computer instructions, which may, for instance, be organized as an object or procedure. Nevertheless, the executables of an identified module need not be physically located together but may include disparate instructions stored in different locations which, when joined logically together, include the module and achieve the stated purpose for the module. Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices.
Similarly, operational data may be identified and illustrated herein within modules and may be embodied in any suitable form and organized within any suitable type of data structure. Operational data may be collected as a single data set or may be distributed over different locations including over different storage devices.
