306 `DRM_IOCTL_I915_GEM_CONTEXT_CREATE` which is identified by a 32-bit
307 integer. Such a context should be viewed by user-space as -loosely-
308 analogous to the idea of a CPU process of an operating system. The i915

328 GPUs each context has its own translation table, called Per-Process
330 PPGTT is named per-process it is actually per context. When user space
