267 Intel GPU Basics
270 An Intel GPU has multiple engines. There are several engine types.
284 The Intel GPU family is a family of integrated GPU's using Unified
285 Memory Access. For having the GPU "do work", user space will feed the
286 GPU batch buffers via one of the ioctls `DRM_IOCTL_I915_GEM_EXECBUFFER2`
288 instruct the GPU to perform work (for example rendering) and that work
291 `DRM_IOCTL_I915_GEM_CREATE`). An ioctl providing a batchbuffer for the GPU
306 Gen4, also have that a context carries with it a GPU HW context;
307 the HW context is essentially (most of at least) the state of a GPU.
308 In addition to the ordering guarantees, the kernel will restore GPU
310 user space the need to restore (most of at least) the GPU state at the
315 The GPU has its own memory management and address space. The kernel
316 driver maintains the memory translation table for the GPU. For older
328 the GPU address when a GEM BO is assigned a GPU address and the kernel
332 refer to GPU-addresses so that the kernel can edit the buffer correctly.
