+Generic Timer
+=============
+
+The following are the requirements related to ARM Generic Timer [1] interface
+exposed by Xen to Arm64 domains.
+
+Probe the Generic Timer device tree node from a domain
+------------------------------------------------------
+
+`XenSwdgn~arm64_generic_timer_probe_dt~1`
+
+Description:
+Xen shall generate a device tree node for the Generic Timer (in accordance to
+ARM architected timer device tree binding [2]) in the domain device tree.
+
+Rationale:
+
+Comments:
+Domains can detect the presence of the Generic Timer device tree node.

+
+Rationale:
+
+Comments:
+
+Covers:

+
+Access physical timer from a domain
+-----------------------------------
+
+`XenSwdgn~arm64_generic_timer_access_physical_timer~1`
+
+Description:

+
+Rationale:
+
+Comments:
+
+Covers:

+
+Trigger the virtual timer interrupt from a domain
+-------------------------------------------------
+
+`XenSwdgn~arm64_generic_timer_trigger_virtual_interrupt~1`
+
+Description:
+Xen shall generate virtual timer interrupts to domains when the virtual timer
+condition is met.
+
+Rationale:
+
+Comments:
+
+Covers:
+ - `XenProd~emulated_timer~1`
+
+Trigger the physical timer interrupt from a domain
+--------------------------------------------------
