  • Patent number: 12353733
    Abstract: Autonomous power control is provided on a storage system to enable service level maximum response time controls to be achieved, while also minimizing power consumption, by enabling service level minimum response times to be specified and enforced. A workload/CPU clock speed model is created for the storage system correlating a maximum number of IOPS that the storage system can process for different CPU clock speeds for each workload type. A service level agreement specifies a maximum storage system response time. A storage system minimum response time is also specified, that is used to identify a target CPU clock speed for the workload type being provided by a host. The CPU clock speed is lowered to reduce energy consumption by the storage system toward the target CPU clock speed, and storage system performance is monitored to ensure that the storage system complies with the storage system maximum response time.

  • Patent number: 12353568
    Abstract: A storage enclosure of an information handling system includes multiple storage drives, and an expander device. The storage drives include one or more self-encrypting drives (SEDs). The expander device determines whether a SED enables a power disable capability. In response to detection that the SED enables the power disable capability, the expander device monitors a link status between the information handling system and the storage enclosure. In response to a link status change being detected, the expander device waits a period of time and determines the link status after the period of time. If the link status is link down, the expander device implements a power cycle in the storage drives. After the power cycle of the storage drives, the expander device sets the drives to a locked state.

  • Patent number: 12326810
    Abstract: A performance monitor provides cache miss stall and memory bandwidth usage metric samples to a resource exhaustion detector. The detector can detect the presence of last-level cache and memory bandwidth exhaustion conditions based on the metric samples. If cache miss stalls and memory bandwidth usage are both trending up, the detector reports a memory bandwidth exhaustion condition to a resource controller. If cache miss stalls are trending up and memory bandwidth usage is trending down, the detector reports a last-level cache exhaustion condition to the resource controller. The resource controller can allocate additional last-level cache or memory bandwidth to the processor unit to remediate the resource exhaustion condition. If bandwidth-related metric samples indicate that a processor unit may be overloaded due to receiving high bandwidth traffic, the resource controller can take a traffic rebalancing remedial action.

  • Patent number: 12232041
    Abstract: If a secure element accesses a resource that is separate from the secure element, conducting a secure transaction can be inefficient in terms of power or time. Power usage is inefficient if the resource is never permitted to sleep, and transaction time is inefficient if the resource is permitted to sleep, and the user experiences a delay. To enable dual efficiency, a resource entity is permitted to be powered down. The resource entity is then powered up speculatively by an activation controller. The activation controller predicts an upcoming secure transaction based on sensor output, such as a position fix or a detected electromagnetic field. Based on monitored sensor output, the activation controller issues an activation signal to power up the secure element or the resource entity prior to initiation of the upcoming secure transaction. Thus, power can be conserved without introducing a transaction-processing latency.

  • Patent number: 12204470
    Abstract: Dynamically controlled interrupt coalescing is performed by enabling interrupt coalescing when the queue depth of the submission queue is high and disabling interrupt coalescing when the queue depth of the submission queue is low to maintain a required quality of service for a solid state drive. The minimum number of completions in the completion queue to trigger an interrupt is modified based on the queue depth of the submission queue. The minimum number of completions is increased when there is an increase in the queue depth of the submission queue and decreased when there is a decrease in the queue depth of the submission queue.

  • Patent number: 12193082
    Abstract: An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.

  • Patent number: 12181941
    Abstract: Systems, apparatuses, and methods for implementing a dynamic power estimation (DPE) unit that adapts weights in real-time are described. A system includes a processor, a DPE unit, and a power management unit (PMU). The DPE unit generates a power consumption estimate for the processor by multiplying a plurality of weights by a plurality of counter values, with each weight multiplied by a corresponding counter. The DPE unit calculates the sum of the products of the plurality of weights and plurality of counters. The accumulated sum is used as an estimate of the processor's power consumption. On a periodic basis, the estimate is compared to a current sense value to measure the error. If the error is greater than a threshold, then an on-chip learning algorithm dynamically adjust the weights. The PMU uses the power consumption estimates to keep the processor within a thermal envelope.

  • Patent number: 12164774
    Abstract: Provided is a method for regulating, via a hardware performance throttling block (PTB) of a memory module, the performance of a memory system in response to read and write requests from a processing system which hosts the memory system. The host system sends memory service requests to the memory system in the form of memory read requests and memory write requests. The host system sends requests to throttle, that is, to limit the responses of the memory system in response to memory requests; the host system sends to the memory system various parameters indicative of current memory usage. In response to the throttling request, the PTB of the memory module either stops any reception of memory requests, or limits (throttles) the number of memory read requests, write requests, or both for a specified number of clock/command cycles. The PTB also determines when full, un-throttled performance may be resumed.

  • Patent number: 12153935
    Abstract: A method for operating a control unit of a motor vehicle, wherein a state management module of a runtime environment initiates a standby mode of the runtime environment as a function of a stop request. The invention provides that, as a function of the stop request, the state management module first sends out to at least one application a respective backup request which requests the respective application to store respective predetermined runtime data in a non-volatile data memory, and then, however, if a resume request is subsequently received within a waiting time period, the normal operating mode is continued without the planned switch-over to the standby mode.
