26 * Batchbuffer and command submission module.
28 * Every API draw call results in a number of GPU commands, which we
29 * collect into a "batch buffer". Typically, many draw calls are grouped
30 * into a single batch to amortize command submission overhead.
32 * We submit batches to the kernel using the I915_GEM_EXECBUFFER2 ioctl.
33 * One critical piece of data is the "validation list", which contains a
34 * list of the buffer objects (BOs) which the commands in the GPU need.
35 * The kernel will make sure these are resident and pinned at the correct
36 * virtual memory address before executing our batch. If a BO is not in
37 * the validation list, it effectively does not exist, so take care.
