Abstract: Aspects of the disclosure provide techniques for retransmitting transaction layer packets (TLPs) for which a negative acknowledgment (NACK) is received without retransmitting previously transmitted TLPs that are correctly received, yet out-of-sequence, by a receiver. A receiver (e.g., a receiving link partner) can provide a transmitter (e.g., a transmitting link partner) with a NACK that includes a starting sequence number (SSN) and an ending sequence number (ESN), which can notify the transmitter about the packets for retransmission and/or packets that can be purged from a transmit buffer of the transmitter.

Abstract: Aspects relate to link speed for a peripheral component interconnect. In one aspect, an apparatus includes an interface circuit configured to provide an interface with a multiple lane data link, the data link having a first set of lanes in an active state and a second set of lanes in an idle state and a controller. The controller is configured to receive a request at the controller to change a data rate of the data link to a requested data rate, change the second set of lanes from an idle state to an active state, train the second set of lanes to the requested data rate, transfer data traffic from the first set of lanes to the second set of lanes after the training, and transmit the data traffic on the second set of lanes.

Abstract: A new peripheral component interconnect express (PCIe) link state can enhance power saving capabilities of a PCIe link operating in a flow control unit (FLIT) mode. A device can operate a data link with a host in a FLIT mode using fixed-sized packets, the data link being in a partial width link state (PLS) in which a first set of lanes of the data link are in an electrical idle state and a second set of lanes of the data link are in an active state available for data traffic with the host. The device can transition one or more lines of the second set of lanes from the PLS to a partial width standby link state (PSLS) in which the one or more lines of the second set of lanes are in a standby state that has lower power consumption than the active state.

Abstract: Aspects relate to power management for a peripheral component interconnect. Transmit traffic activity may be monitored for a peripheral component interconnect express (PCIe) link. Receive traffic activity may also be monitored for the link A first power of transmit lines of the link is managed as a transmit group in accordance with the transmit traffic activity. A second power of the receive lines of the link are managed as a receive group in accordance with the receive traffic activity. The first power of the transmit lines is managed independently of the second power of the receive lines.

Abstract: Migration of a user of a computing device to accept an updated version of a software feature to the exclusion of a prior version of the software feature is implemented without user friction. Telemetry data corresponding to use of the updated version and of the prior version is stored. The telemetry data is evaluated utilizing a trained machine learning model trained using external telemetry data with respect to use of the updated version and to use of the prior version. A migration acceptance value indicative of whether the user will accept use of the updated version to exclusion of the prior version is calculated. The migration acceptance value is compared to a threshold value determined by the trained model. If the migration acceptance value exceeds the threshold value, the prior version is excluded from the user profile.

Abstract: Various embodiments include methods and devices for implementing a Peripheral Component Interconnect Express (PCIe) link state transition by a computing device. Embodiments may include comprising retrieving, by a PCIe controller, PCIe link configuration data from a memory for a PCIe link in a fast recovery low power state of a link training status and state machine (LTSSM), and re-initializing, by the PCIe controller, the PCIe link using the PCIe link configuration data retrieved from the memory. Embodiments may further include maintaining the PCIe link configuration data in the memory for the PCIe link in the fast recovery low power state of the LTSSM by providing auxiliary power to PCIe configuration registers for the PCIe controller.

Abstract: Disclosed herein is system and method for examining relevancy of documents. The system, based on request from the user extracts documents from one or more data sources. The system then obtains from the user, user intention information and user queries. The system then analyses each document with respect to user intention information in order to determine a relevancy level of each document. The relevancy level is indicated in the form of a ranking score. The system ranks and displays the documents to the user in the order of their scores. The system also highlights important excerpts from the documents and provides one or more responses to the one or more user queries submitted by the user for each and every document. Based on the received responses, user provides feedback for further training the system, thereby achieving better accuracy.

Abstract: Methods and systems are provided to learn and apply a mapping function from data representing concentrations of atomic elements in a geological formation (or other data corresponding thereto) to mineral component concentrations in the geological formation (and/or from mineral component concentrations to reconstructed elemental concentrations in the geological formation). The mapping function can be derived from a trained neural network (such as an autoencoder). The output of the mapping function can be used to determine estimates of one or more formation properties, such as formation matrix density, formation porosity, matrix Sigma, formation saturation, other formation property, or combinations thereof.

Abstract: Securely performing file operations. A method includes determining a licensing characteristic assigned to a file. When the licensing characteristic assigned to the file meets or exceeds a predetermined licensing condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the guest operating system. When the licensing characteristic assigned to the file does not meet or exceed the predetermined licensing condition, then the method includes performing the file operation on the file in the guest operating system while preventing the file operation from being performed directly in the host operating system.
