按照AMD的说法:
“Command Processor: An application sends commands (such as
set memory addresses and formats, invalidate and flush caches,
and start program) to the DPVM by writing them into command
buffers in memory, and then sending them to the DPVM.
Methods to open and close a device, submit a command buffer,
and wait for a command buffer are exported via a shared library.
Global information, such as memory pool sizes and addresses are
returned upon device open. This interface simplifies device
communication, and eliminates unwanted policy.“ |
