Inter-processor communication techniques in a multiple-processor computing platform

A host device comprising:

• one or more processors;
• and
• a memory buffer interface executing on the one or more processors and configured to receive an instruction that includes information specifying whether an immediate mode should be enabled for a shared memory space, and selectively enable the immediate mode for the shared memory space based on the information specifying whether the immediate mode should be enabled, the shared memory space being accessible by the host device and by a graphics processing unit (GPU).

An apparatus comprising:

• means for receiving an instruction that includes information specifying whether an immediate mode should be enabled for a shared memory space that is accessible by a host device and by a graphics processing unit (GPU);
• and
• means for selectively enabling the immediate mode for the shared memory space based on the information specifying whether the immediate mode should be enabled.

A computer-readable medium comprising instructions that cause one or more processors to:

• receive an instruction that includes information specifying whether an immediate mode should be enabled for a shared memory space that is accessible by a host device and by a graphics processing unit (GPU);
• and
• selectively enable the immediate mode for the shared memory space based on the information specifying whether the immediate mode should be enabled.

A graphics processing unit (GPU) comprising:

• a GPU cache associated with a memory;
• and
• one or more processing modules configured to selectively use caching services of the GPU cache to execute at least one of a read operation and a write operation with respect to a memory space of the memory in response to receiving information specifying whether caching services should be used for executing at least one of read operations and write operations with respect to the memory space.

A method comprising:

• selectively using, with one or more processing modules of a graphics processing unit (GPU), caching services of GPU cache associated with a memory to execute at least one of a read operation and a write operation with respect to a memory space of the memory in response to receiving information specifying whether caching services should be used for executing at least one of read operations and write operations with respect to the memory space.

An apparatus comprising:

• and
• means for selectively using caching services of the GPU cache to execute at least one of a read operation and a write operation with respect to a memory space of the memory in response to receiving information specifying whether caching services should be used for executing at least one of read operations and write operations with respect to the memory space.

A computer-readable medium comprising instructions that cause one or more processors to:
