Patent number: 10642645Abstract: Technology for managing operational modes of a network adapter is disclosed. The technology includes features for selectively preempting (e.g., canceling, suspending, deferring, pausing, changing to a “no-op” state, changing to a passive state, or otherwise deprioritizing) execution for a current operational mode of the network adapter, executing a requested network control operation, and optionally restoring the preempted operational mode. The operational mode may be selectively preempted based on priority information associated with the current operational mode and the requested network control operation.Type: GrantFiled: June 21, 2013Date of Patent: May 5, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Henrique Filgueiras, Mitesh Desai, Mahmoud Elhaddad, Mingtzong Lee, Yesayi Hovnanyan, Mukund Sankaranarayan, Nar Ganapathy

Patent number: 10530713Abstract: Technology for managing queuing resources of a shared network adapter is disclosed. The technology includes selectively transferring data from data transmission sources to a queue of the shared network adapter based on status indications from the shared network adapter regarding availability of queuing resources at the shared network adapter. In addition, the technology also includes features for selectively controlling transfer rates of data to the shared network adapter from applications, virtual network stations, other virtual adapters, or other data transmission sources. As one example, this selective control is based on how efficiently data from these data transmission sources are transmitted from the shared network adapter.Type: GrantFiled: August 15, 2016Date of Patent: January 7, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Mahmoud Elhaddad, Mukund Sankaranarayan, Mitesh Desai, Henrique Filgueiras, Mingtzong Lee, Nar Ganapathy

Publication number: 20140379884Abstract: Technology for prioritizing and executing network control operations is disclosed. The technology includes prioritizing requested network control operations against other network control operations and executing network control operations based on this prioritization. The prioritization may be based on priority information and classes with which the network control operations are associated. The classes may be based on expected durations of time for executing the network control operations. The technology also includes prioritizing and executing network control operations in a virtualized networking system.Type: ApplicationFiled: June 21, 2013Publication date: December 25, 2014Inventors: Henrique Filgueiras, Mitesh Desai, Mahmoud Elhaddad, Mingtzong Lee, Yesayi Hovnanyan, Mukund Sankaranarayan, Nar Ganapathy

Patent number: 8434098Abstract: A device driver includes a kernel mode and a user-mode module. The device driver may access device registers while operating in user-mode to promote system stability while providing a low-latency software response from the system upon interrupts. The device driver may include kernel stubs that are loaded into the operating system, and may be device specific code written. The stubs may be called by a reflector to handle exceptions caught by the stubs. A reset stub may be invoked by the reflector when the user-mode module or host terminates abruptly or detects an interrupt storm. The reset stub may also be invoked if errant direct memory access DMA operations are being performed by a hardware device. The reset stub may ensure that hardware immediately stops unfinished DMA from further transfer, and may be called by the user-mode driver module.Type: GrantFiled: February 7, 2008Date of Patent: April 30, 2013Assignee: Microsoft CorporationInventors: Mingtzong Lee, Peter Wieland, Nar Ganapathy, Ulfar Erlingson, Martin Abadi, John Richardson

Patent number: 8379735Abstract: A process to detect video glitches and audio-video synchronization errors arising during playback or capture. The process encodes an external time stamp into video and audio streams directly at the output of a digital media playback device. The process captures the stamped video and audio streams and analyzes the external stamp by comparing it with a presentation time stamp and a capture time stamp.Type: GrantFiled: May 15, 2006Date of Patent: February 19, 2013Assignee: Microsoft CorporationInventors: Mingtzong Lee, Huseyin S.

Patent number: 8185783Abstract: A device driver includes a kernel stub and a user-mode module. The device driver may access device registers while operating in user-mode to promote system stability while providing a low-latency software response from the system upon interrupts. Upon receipt of an interrupt, the kernel stub may run an interrupt service routine and write information to shared memory. Control is passed to the user-mode module by a reflector. The user-mode module may then read the information from the shared memory to continue servicing the interrupt.Type: GrantFiled: November 22, 2007Date of Patent: May 22, 2012Assignee: Microsoft CorporationInventors: Mingtzong Lee, Peter Wieland, Nar Ganapathy, Ulfar Erlingsson, Martin Abadi, John Richardson

Patent number: 7683906Abstract: Video frame buffers are controlled using a sequence of new-frame-indicators (e.g., FLIP) and no-new-frame-indicators (e.g., NOFLIP) in a frame indicator queue that is accessed with each display refresh. Video samples are loaded into a chain of video frame buffers that is “rotated” during the vertical blanking signal of the display to swap an old frame buffer out for a new frame buffer. The rotations of the frame buffer chain are controlled based on the frame indicators in the frame indicator queue to present new video samples to the display in a regular pattern, thereby providing smooth video playback.Type: GrantFiled: February 22, 2006Date of Patent: March 23, 2010Assignee: Microsoft CorporationInventors: Jay Senior, Stephen J. Estrop, Anuj B. Gosalia, David R. Blythe, Joseph C. Ballantyne, Kan Qiu, Gregory D. Swedberg, John (Mingtzong) Lee

Publication number: 20090210888Abstract: A device driver includes a hypervisor stub and a virtual machine driver module. The device driver may access device registers while operating within a virtual machine to promote system stability while providing a low-latency software response from the system upon interrupts. Upon receipt of an interrupt, the hypervisor stub may run an interrupt service routine and write information to shared memory. Control is passed to the virtual machine driver module by a reflector. The virtual machine driver module may then read the information from the shared memory to continue servicing the interrupt.Type: ApplicationFiled: February 14, 2008Publication date: August 20, 2009Applicant: Microsoft CorporationInventors: Mingtzong Lee, Peter Wieland, Nar Ganapathy, Ulfar Erlingsson, Martin Abadi, John Richardson

Patent number: 7146458Abstract: One aspect of the present invention relates to an information appliance for handling streaming information for storage in a circular buffer having a plurality of partitions defined by boundaries. The information appliance includes receiving streaming information from a source of streaming information and forming data blocks wherein each data block includes a payload field capable of holding a portion of the streaming information and an identification field indicative of the source of the streaming information. At least one data block is written to the circular buffer to partially fill a partition and at least one padding block is generated having a field indicative of non-streaming information and having a size being a function of remaining space in the partition. The padding block is written to the circular buffer adjacent a boundary of the partition.Type: GrantFiled: April 1, 2005Date of Patent: December 5, 2006Assignee: Microsoft CorporationInventors: Serge Smirnov, Mingtzong Lee, Christopher W.
