+ * page size restrictions when dealing with I915_MEMORY_CLASS_DEVICE
+ * objects. Specifically the hardware only supports 64K or larger GTT
+ * page sizes for such memory. The kernel will already ensure that all
+ * I915_MEMORY_CLASS_DEVICE memory is allocated using 64K or larger page
+ * sizes underneath.
+ *
+ * Note that the returned size here will always reflect any required
+ * rounding up done by the kernel, i.e 4K will now become 64K on devices
+ * such as DG2.
+ *
+ * Special DG2 GTT address alignment requirement:
+ *
+ * The GTT alignment will also need to be at least 2M for such objects.
+ *
+ * Note that due to how the hardware implements 64K GTT page support, we
+ * have some further complications:
+ *
+ * 1) The entire PDE (which covers a 2MB virtual address range), must
+ * contain only 64K PTEs, i.e mixing 4K and 64K PTEs in the same
+ * PDE is forbidden by the hardware.
+ *
+ * 2) We still need to support 4K PTEs for I915_MEMORY_CLASS_SYSTEM
+ * objects.
+ *
+ * To keep things simple for userland, we mandate that any GTT mappings
+ * must be aligned to and rounded up to 2MB. The kernel will internally
+ * pad them out to the next 2MB boundary. As this only wastes virtual
+ * address space and avoids userland having to copy any needlessly
+ * complicated PDE sharing scheme (coloring) and only affects DG2, this
+ * is deemed to be a good compromise.
