+/**
+ * DOC: Xe IOCTL Extensions
+ *
+ * Before detailing the IOCTLs and its structs, it is important to highlight
+ * that every IOCTL in Xe is extensible.
+ *
+ * Many interfaces need to grow over time. In most cases we can simply
+ * extend the struct and have userspace pass in more data. Another option,
+ * as demonstrated by Vulkan's approach to providing extensions for forward
+ * and backward compatibility, is to use a list of optional structs to
+ * provide those extra details.
+ *
+ * The key advantage to using an extension chain is that it allows us to
+ * redefine the interface more easily than an ever growing struct of
+ * increasing complexity, and for large parts of that interface to be
+ * entirely optional. The downside is more pointer chasing; chasing across
+ * the __user boundary with pointers encapsulated inside u64.
+ *
+ * Example chaining:
+ *
+ * .. code-block:: C
+ *
+ * struct drm_xe_user_extension ext3 {
+ * .next_extension = 0, // end
+ * .name = ...,
+ * };
+ * struct drm_xe_user_extension ext2 {
+ * .next_extension = (uintptr_t)&ext3,
+ * .name = ...,
+ * };
+ * struct drm_xe_user_extension ext1 {
+ * .next_extension = (uintptr_t)&ext2,
+ * .name = ...,
+ * };
+ *
+ * Typically the struct drm_xe_user_extension would be embedded in some uAPI
+ * struct, and in this case we would feed it the head of the chain(i.e ext1),
+ * which would then apply all of the above extensions.
+*/
