  • Patent number: 8933947
    Abstract: Disclosed herein are systems, apparatuses, and methods for enabling efficient reads to a local memory of a processing unit. In an embodiment, a processing unit includes an interface and a buffer. The interface is configured to (i) send a request for a portion of data in a region of a local memory of an other processing unit and (ii) receive, responsive to the request, all the data from the region. The buffer is configured to store the data from the region of the local memory of the other processing unit.

  • Patent number: 8842126
    Abstract: In an embodiment, a method of processing memory requests in a first processing device is provided. The method includes generating a memory request associated with a memory address located in an unpinned memory space managed by an operating system running on a second processing device; and responsive to a determination that the memory address is not resident in a physical memory, transmitting a message to the second processing device. In response to the message, the operating system controls the second processing device to bring the memory address into the physical memory.

  • Patent number: 8823717
    Abstract: Methods and systems relating to providing constants are provided. In an embodiment, a method of providing constants in a processing device includes copying a constant of a first constant buffer to a second constant buffer, the first and second constant buffers being included in a ring of constant buffers and a size of the ring being one greater than a number of processes that the processing device can process concurrently, updating a value of the constant in the second buffer, and binding a command to be executed on the processing device to the second constant buffer.

  • Publication number: 20140022263
    Abstract: The desire to use an Accelerated Processing Device (APD) for general computation has increased due to the APD's exemplary performance characteristics. However, current systems incur high overhead when dispatching work to the APD because a process cannot be efficiently identified or preempted. The occupying of the APD by a rogue process for arbitrary amounts of time can prevent the effective utilization of the available system capacity and can reduce the processing progress of the system. Embodiments described herein can overcome this deficiency by enabling the system software to pre-empt a process executing on the APD for any reason. The APD provides an interface for initiating such a pre-emption. This interface exposes an urgency of the request which determines whether the process being preempted is allowed a grace period to complete its issued work before being forced off the hardware.

  • Publication number: 20130155077
    Abstract: A method of determining priority within an accelerated processing device is provided. The accelerated processing device includes compute pipeline queues that are processed in accordance with predetermined criteria. The queues are selected based on priority characteristics and the selected queue is processed until a time quantum lapses or a queue having a higher priority becomes available for processing.

  • Publication number: 20130160019
    Abstract: A method resumes an accelerated processing device (APD) wavefront in which a subset of elements have faulted. A restore command for a job including a wavefront is received. A list of context states for the wavefront is read from a memory associated with a APD. An empty shell wavefront is created for restoring the list of context states. A portion of not acknowledged data is masked over a portion of acknowledged data within the restored wavefronts.

  • Publication number: 20130145202
    Abstract: A method tolerates virtual to physical address translation failures. A translation request is sent from a graphics processing device to a translation mechanism. The translation request is associated with a first wavefront. A fault notification is received within an accelerated processing device (APD) from the translation mechanism that a request cannot be acknowledged. The first wavefront is, stored within a shader core of the APD if the fault notification is received. The first wavefront is replaced with a second wavefront if the fault notification is received, the second wavefront being ready to be executed.

  • Publication number: 20120229481
    Abstract: A method, system, and computer program product are disclosed for providing improved access to accelerated processing device compute resources to user mode applications. The functionality disclosed allows user mode applications to provide commands to an accelerated processing device without the need for kernel mode transitions in order to access a unified ring buffer. Instead, applications are each provided with their own buffers, which the accelerated processing device hardware can access to process commands. With full operating system support, user mode applications are able to utilize the accelerated processing device in much the same way as a CPU.
