Publication number: 20230350815Abstract: Disclosed are various embodiments for various approaches for implementing trust domains to provide boundaries between PCIe devices connected to the same PCIe switch. A first trust identifier can be assigned to a first virtual machine hosted by the computing device. The first trust identifier can also be assigned to a first PCIe device assigned to the first virtual machine. Later, it can be determined that a second PCIe device connected to the PCIe switch is assigned a second trust identifier assigned to a second virtual machine. An Address Control Services (ACS) direct translated bit for peer-to-peer memory requests in the PCIe switch can be disabled in response to a determination that the second PCIe device is associated with the second trust identifier assigned to the second virtual machine.Type: ApplicationFiled: June 23, 2023Publication date: November 2, 2023Inventors: Srihari Venkatesan, Sunil Kotian, Andrei Warkentin, Kalaiselvi Sengottuvel

Publication number: 20230229609Abstract: Techniques for implementing IOMMU-based DMA tracking for enabling live migration of VMs that use passthrough physical devices are provided. In one set of embodiments, these techniques leverage an IOMMU feature known as dirty bit tracking which is available in most, if not all, modern IOMMU implementations. The use of this feature allows for the tracking of passthrough DMA in a manner that is device/vendor/driver agnostic, resulting in a solution that is universally applicable to all passthrough physical devices.Type: ApplicationFiled: January 18, 2022Publication date: July 20, 2023Inventors: Alexander Dean Gotsis, Jiajun Cao, Radu Rugina, James Eugene Chow, Srihari Venkatesan, Jeffrey W.

Patent number: 10949883Abstract: The disclosed technology includes system and method for discovering key places for a mobile device based on historical location data associated with the mobile device. The key places are discovered by mapping the historical location data into predefined land areas in a geographical region, aggregating the historical location data into time interval sessions, selecting a first set of the predefined areas based on density of location data in each of the predefined land areas, and filtering the first set of the predefined areas to obtain the key places. The key places are used to estimate one or more travel routes routinely taken by a user of the mobile device, and to build an association database, where one or more billboards and/or points of interests near the travel routes are associated with the mobile device or its user. Information documents for delivering to the mobile device are selected based at least on data in the association database.Type: GrantFiled: January 2, 2018Date of Patent: March 16, 2021Assignee: XAD, INCInventors: Feng Wan, Srihari Venkatesan, Saravana Ravindran, Shanshan Tuo, Prakash Muttineni, Deborah Zhang, Huitao Luo, Shashi Seth

Patent number: 10939258Abstract: The present disclosure provides a mobile advertising platform in which mobile user locations and other information are translated into indications of mobile user intent to approach certain businesses, and advertisers can fill mobile advertising requests or choose to price their bids for mobile supplies based on such indications. In certain embodiments, pre-defined places associated with business/brand names are created, and mobile advertising requests are processed to determine if the associated with mobile devices have triggered any of these pre-defined places. If a mobile advertising request is determined to have triggered one or more of the pre-defined places, it is annotated with the triggered place(s), and advertisements are selected based on the triggered places and other factors. The annotated requests with the triggered places can also be commodities in a location market place, which are auctioned to the mobile advertisers, who can place their bids on the triggered places.Type: GrantFiled: May 19, 2015Date of Patent: March 2, 2021Assignee: XAD, INC.Inventors: Huitao Luo, Nishant Khatri, Prakash Muttineni, Srihari Venkatesan, Dipanshu Sharma, Stephen Anderson, George Rekouts, Jonathan Schwartz, David Chock, Shanshan Tuo, Can Liang

Patent number: 9886703Abstract: A method of delivering location-based information comprises receiving a request including a location indicator from a packet-based network and translating the location indicator into a probabilistic representation of one or more possible locations of a mobile user based on historical data collected from mobile devices. By generating the probabilistic user location representation, the method can be used to deal with the inherent uncertainty in user location data, particularly in a mobile world. In some embodiments, this is done by using validation, context analysis, creation of consistent groups, and probability allocation procedures. Location-based document retrieval can be enabled using the probabilistic user location representation.Type: GrantFiled: May 19, 2015Date of Patent: February 6, 2018Assignee: xAd, Inc.Inventors: Prakash Muttineni, Nishant Khatri, Srihari Venkatesan, Chi-Chao Chang, Huitao Luo, Mauricio Mediano, Dipanshu Sharma

Patent number: 9210540Abstract: A geographic document retrieval method (GDR) can be executed by a computer system to index, retrieve and rank geographical documents. Textual and spatial attributes of geographical documents are indexed separately using inverted index and spatial index, respectively. Spatial attributes of a document are represented as one or more contiguously closed regions of arbitrary shapes. Upon receiving an input query carrying a geographic representation of a location using arbitrary regions, the GDR method retrieves one or more documents by executing an overlap test between arbitrary regions from the query and the arbitrary regions associated with the documents.Type: GrantFiled: April 19, 2013Date of Patent: December 8, 2015Assignee: xAd, Inc.Inventors: Chi-Chao Chang, Mauricio Mediano, Srihari Venkatesan, Prakash Muttineni, Dipanshu Sharma
