Abstract: Automatic-switching and deployment of software (SW)- or firmware (FW)-based USB4 connection managers (CMs) and associated methods, apparatus, software and firmware. A handshake is defined between BIOS and an operating system (OS) to discover supported CM capability and dynamically switch from a FW CM to a SW CM and visa verse if there is a mismatch. In addition, a mechanism is defined to deploy the correct FW or SW CM driver based on class code, 2-part or 4-part ID. Support for continued USB4 operation during an OS upgrade or downgrade is provided, while ensuring that the best possible CM solution is used based on the advertised platform and OS capability. USB4 controllers support a pass-through mode under which the host controller FW redirects control packets sent between an SW CM and a USB4 fabric, and a FW CM mode under which control packets are communicated between the host controller FW and the USB4 fabric to configure USB4 peripheral devices and/or USB4 hubs in the USB4 fabric.

Abstract: A method and apparatus for matching parent processor address translations to media processors' address translations and providing concurrent memory access to a plurality of media processors through separate translation table information. In particular, a page directory for a given media application is copied to a media processor's page directory when the media application allocates memory that is to be shared by a media application running on the parent processor and media processors.

Abstract: Various techniques for enabling the control and monitoring of a USB device mode controller to a USB-C connector, for the performance of a USB device mode data connection, are disclosed herein. In an example, a computing system that includes multiple USB-C connectors but a single USB device mode controller may manage the mapping of the controller to a particular connector, through operations that identify the mapping and the characteristics of the connector, process a request to change the mapping of the device mode controller, and perform the change to the mapping of the device mode controller. Such a change may include a disconnection or reassignment of a particular USB-C connector to the controller. Further examples to determine the availability of a USB device mode controller, and respond to a scenario where the USB device mode controller is not available, are also disclosed.

Abstract: A first device is determined as connected to a first one of a plurality of ports of a root complex. Addresses are assigned corresponding to a first hierarchy of devices including the first device. A second device is determined as connected through a mapping portal bridge at a second one of the ports of the root complex, the second device included in another second hierarchy of devices. A mapping table is generated that corresponds to the mapping portal bridge. The mapping table defines a translation between addressing used in a first view of a configuration address space of the system and addressing used in a second view of the configuration address space. The first view includes a view of the root complex and the second view includes a view corresponding to the second hierarchy of devices, the first hierarchy of devices being addressed according to the first view.

Abstract: An apparatus includes an extended capability register and an input/output (I/O) memory management circuitry. The I/O memory management circuitry is to receive, from an I/O device, an address translation request referencing a guest virtual address associated with a guest virtual address space of a virtual machine. The I/O memory management circuitry may translate the guest virtual address to a guest physical address associated with a guest physical address space of the virtual machine, and, responsive to determining that a value stored by the extended capability register indicates a restrict-translation-request-response (RTRR) mode, transmit, to the I/O device, a translation response having the guest physical address.

Abstract: Examples include techniques for dynamically modifying a platform form factor of a mobile device. In some examples, a system may include a split memory array having a first memory within a docking system and a second memory element within a small form factor (SFF) mobile device. A platform form factor determination component may dynamically select between multiple platform form factors based on a determination that the SFF mobile device is coupled with the docking system. An interface logic component may access the first memory storage of the docking system during a memory (e.g., graphics) computation when the mobile device is physically and electrically/communicably coupled with the docking system to allow the SFF mobile device to have full LFF functionality. When the SFF mobile device is disconnected from the docking system, the interface logic component may access only the second memory storage of the SFF mobile device to provide SFF functionality.

Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.

Abstract: Bridge logic is provided to receive a request from a device, where the request references an address of a secondary address space. The secondary address space corresponds to a subset of addresses in a configuration address space of a system, and the secondary address space corresponds to a first view of the configuration address space. The bridge logic uses a mapping table to translate the address into a corresponding address in the configuration address space, where addresses of the configuration address space correspond to a different second view of the configuration address space.
