摘要： A hardware accelerator device detects duplicate data blocks independently from a processor of an information handling system. The device includes an interface, a hash function, a bloom filter, and a data comparator. The interface receives data blocks. The hash function determines a hash of a received data block. The bloom filter includes comparison hashes, each associated with a comparison data block. The bloom filter determines if the hash matches a comparison hash. The data comparator directs the interface to receive the comparison block when the hash matches the comparison hash, and compares the received data block with the comparison data block to determine if they are identical. The device stores a pointer when the data comparison block determines that the blocks are identical.

摘要： An information handling system includes a processor that detects a cache flush request of a memory device within the processor, and identifies multiple blocks of data within an address space associated with the cache flush request. The processor groups the multiple blocks of data into a single composite block of data, and compresses the composite block of data. The processor stores the compressed composite block of data, and stores metadata for the compressed composite block of data. The metadata includes information for both the composite block of data and information for each of the multiple blocks of data.

摘要： A dual in-line memory module (DIMM) includes a memory storage device having data rows and redundant rows. The DIMM further includes a post-package repair module configured to remap an address within the DIMM physical address space from a data row to a redundant row. A memory controller is configured to determine an exact number of un-remapped redundant rows.

摘要： A management controller sends a first firmware measurement request to verify integrity of a device. The first firmware measurement request is sent at initial power on of the device, and is sent subsequent to negotiating a secure session between the management controller and the device. The management controller verifies a first firmware measurement in a first firmware measurement response to the first firmware measurement request prior to storing the first firmware measurement, and sends a heartbeat request to the device to monitor for a device state change. The management controller may receive a heartbeat acknowledgement from the device in response to the heartbeat request, wherein the heartbeat acknowledgement includes an indication of the device state change. In response to the receipt of the heartbeat acknowledgment that includes the device state change, the management controller sends a second firmware measurement request to the device. The management controller may also verify a second firmware measurement included in a second firmware measurement response to the second firmware measurement request that includes a comparison of the first firmware measurement and the second firmware measurement; and apply a security policy to the device based on the device state change.

摘要： An information handling system includes a plurality of containerized applications, a container service, a hardware device, and a host processor to initialize a host service. The container service is associated with the containerized applications. The hardware device is virtualized to the containerized applications. The host processor identifies the hardware device that is virtualized to the containerized applications. The host processor receives a power notification from the container service. Based on the power notification, the host processor changes a power state of the hardware device.

摘要： An information handling system includes an embedded controller that subsequent to a determination that a power button is activated, may determine a sequence of unplugging a connector from a port within a time threshold and subsequently plugging the connector from the port within another time threshold. The embedded controller may determine a hotkey associated with the sequence of unplugging the connector from the port and subsequently plugging the connector to the port, and execute a function based on the hotkey.

摘要： A reconfigurable haptic interface assembly of an information handling system may comprise a coversheet display layer displaying a key location of a haptic keyboard based on a modified configuration, a contact foil placed between the coversheet layer and a support layer, and a piezoelectric element placed between the contact foil and the support layer receiving an applied mechanical stress near the displayed key location, and transmitting a generated piezo actuation signal via the contact foil. A processor may receive the piezo actuation signal, identify x- and y-coordinate location data describing the displayed key location based, in part, on the piezo actuation signal, identify a keyboard scan code associated with the x- and y-coordinate location data, and send a haptic feedback response signal to the piezoelectric element to generate a haptic feedback at the key location and a digital display may display a key register event.

摘要： An information handling system includes a memory to store one or more solution catalogs for systems within the information handling system, and a processor. The processor fetches the one or more solution catalogs for the systems within the information handling system. The processor further combines specified update packages to create one or more revised solution catalogs. The processor also builds a map of an existing solution catalog with the components being managed with the existing solution catalog. Based on an associated one of the revised solution catalogs, the processor determines compliance for each of the solution catalogs.

摘要： A method may include enabling operation of a time of flight (TOF) proximity sensor at an information handling system and initializing execution of a software service. The method may further include receiving, at the software service, an alert signal from the TOF proximity sensor indicating movement proximate to the information handling system. In response to receiving the alert signal, a camera at the information handling system may be configured to capture an image. The image may be analyzed by a vision system coupled to the camera to determine a gaze direction of a user at the information handling system. Operation of the information handling system may be configured based on the gaze direction.

摘要： An information handling system includes a shared device, first and second compute nodes, and a chassis management controller. The first compute node includes a first management controller, which initiates a firmware update for firmware in the shared device. The first management controller detects that that the firmware update is complete. In response to the firmware update being completed, the management controller sends rollback information for the firmware to the chassis controller. The chassis controller stores the rollback information as a rollback image within a storage location of a memory. The chassis controller further sends the rollback information to the second compute node. The second compute node includes a second management controller, which in turn receives the rollback information from the chassis controller, and updates the rollback information within the second compute node.
