摘要： Embodiment of this disclosure provides a mechanism to extend a workload instruction to include both untranslated and translated address space identifiers (ASIDs). In one embodiment, a processing device comprising a translation manager is provided. The translation manager receives a workload instruction from a guest application. The workload instruction comprises an untranslated (ASID) and a workload for an input/output (I/O) device. The untranslated ASID is translated to a translated ASID. The translated ASID inserted into a payload of the workload instruction. Thereupon, the payload is provided to a work queue of the I/O device to execute the workload based in part on at least one of: the translated ASID or the untranslated ASID.

摘要： An apparatus and method are described for implementing a hybrid layer of address mapping for an IOMMU implementation. For example, one embodiment of a graphics processing apparatus comprises: virtualization circuitry to implement a virtualized execution environment in which a plurality of guest virtual machines (VMs) are to execute and share execution resources of the graphics processing apparatus; an input/output (I/O) memory management unit (IOMMU) to couple the VMs to one or more I/O devices; a hybrid layer address mapping (HLAM) module to combine entries from a per-process graphics translation table (PPGTT) with entries from a global graphics translation table (GGTT) into a first integrated page table, the first integrated page table mapping PPGTT guest page numbers (GPNs) to host page numbers (HPNs) and mapping GGTT virtual GPNs to HPNs; the HLAM to transform a GGTT GPN into a virtual GPN usable to access a corresponding HPN within the first integrated page table in response to a GGTT read/write operation generated by a first guest virtual machine (VM).

摘要： In several embodiments, a graphics processor couples to a virtual machine monitor (VMM) to present a virtual graphics processor to one or more virtual machines. A mediator for the virtual graphics processor synchronously shadows modifications to a guest graphics translation table (GTT) of a virtual machine to a shadow GTT of the VMM using trap and emulate virtualization. If the mediator detects a frequency of modifications to the guest GTT that exceeds a threshold the mediator may then asynchronously shadow at least a portion of the guest GTT to the shadow GTT and rebuild the shadow GTT prior to submitting commands for the virtual graphics processor to the graphics processor.

摘要： Isolated remotely-virtualized computing environment for a mobile device. The mobile device is configured to connect with a virtualized mobile system (VMS) implemented on a remote server. The mobile device accesses local input information via a local input device and a local OS, and transmits the local input information to the VMS. The mobile device further accesses output information from the VMS and passes the output information to be accessed by an output device, such as a display, for instance. Isolation of the output information is maintained where the content of the output information is inaccessible by the OS and the local processes running on the mobile device.
