+## Scalability
+
+### 1GB/2MB super page support
+
+    Status, x86 HVM/PVH: : Supported
+    Status, ARM: Supported
+
+NB that this refers to the ability of guests
+to have higher-level page table entries point directly to memory,
+improving TLB performance.
+This is independent of the ARM "page granularity" feature (see below).
+
+### x86/PVHVM
+
+    Status: Supported
+
+This is a useful label for a set of hypervisor features
+which add paravirtualized functionality to HVM guests 
+for improved performance and scalability.
+This includes exposing event channels to HVM guests.
