A method, device, and system to distribute code and data stores between volatile and non-volatile memory are described. In one embodiment, the method includes storing one or more static code segments of a software application in a phase change memory with switch (PCMS) device, storing one or more static data segments of the software application in the PCMS device, and storing one or more volatile data segments of the software application in a volatile memory device. The method then allocates an address mapping table with at least a first address pointer to point to each of the one or more static code segments, at least a second address pointer to point to each of the one or more static data segments, and at least a third address pointer to point to each of the one or more volatile data segments.

A computing device for performing scheduling operations for graphics hardware is described herein. The computing device includes a central processing unit (CPU) that is configured to execute an application. The computing device also includes a graphics scheduler configured to operate independently of the CPU. The graphics scheduler is configured to receive work queues relating to workloads from the application that are to execute on the CPU and perform scheduling operations for any of a number of graphics engines based on the work queues.

Encoded data decoding techniques. A data decoding agent determines a data segment size for a packet that includes a header and a data segment. The data decoding agent determines a segment end location based, at least in part, on the data segment size. The data decoding agent processes subblocks of data from the data segment. The data decoding agent compares a current location to the segment end location to determine if a current subblock of data from the data segments contains the segment end location. The data decoding agent triggers an exception handler if the current subblock contains the segment end location.
摘要:
A method and apparatus for creating, updating, and using guest physical address (GPA) to host physical address (HPA) shadow translation tables for translating GPAs of graphics data direct memory access (DMA) requests of a computing environment implementing a virtual machine monitor to support virtual machines. The requests may be sent through a render or display path of the computing environment from one or more virtual machines, transparently with respect to the virtual machine monitor. The creating, updating, and using may be performed by a memory controller detecting entries sent to existing global and page directory tables, forking off shadow table entries from the detected entries, and translating GPAs to HPAs for the shadow table entries.

A method and apparatus for authenticated recoverable key distribution are described. In one embodiment, an application key is provided to an integrated chip platform. In one embodiment, the integrated chip platform encrypts the application key with a Key Encryption Key, which is stored within the persistent memory on the platform, and outputs a ChipID and the encrypted application key to enable recovery. In one embodiment, the platform can provide the ChipID to a recovery database to replace a lost encrypted application key. In one embodiment, the ChipID is the public key of a public/private key pair, and the application key is provided to the integrated chip platform by encrypting it using this public key. In one embodiment, the ChipID and the Key Encryption Key are derived from a secret random number programmed into the integrated chip. Other embodiments are described and claimed.

摘要:
Two processing elements in a single platform may communicate securely to allow the platform to take advantage of the certain cryptographic functionality in one processing element. A first processing element, such as a bridge, may use its cryptographic functionality to request a key exchange with a second processing element, such as a graphics engine. Each processing element may include a global key which is common to the two processing elements and a unique key which is unique to each processing element. A key exchange may be established during the boot process the first time the system boots and, failing any hardware change, the same key may be used throughout the lifetime of the two processing elements. Once a secure channel is set up, any application wishing to authenticate a processing element without public-private cryptographic function may perform the authentication with the other processing element which shares a secure channel with the first processing element.

A method and computer readable medium are disclosed. In one embodiment, the method includes enumerating multiple Universal Serial Bus (USB) devices on a computer platform running a multiple virtual machines (VMs). The method also includes assigning each of the USB devices to a VM, wherein each USB device may be assigned to a different VM. The method also includes making each USB device visible only to the VM it is assigned to. The method also includes limiting the bandwidth each of the VMs can schedule its assigned devices within a USB data transfer frame. This will allow all of the VMs to have access to the bandwidth of the frame by avoiding the problem of over-subscription when the schedule is merged.
