+# function to return dynamic PAMT usage in KB
+#
+# This function performs a basic validation of TDX host Dynamic PAMT behavior
+# during the lifecycle of a KVM TDX guest.
+#
+# The check uses the ftrace function profiler to count calls to:
+#   - tdh_phymem_pamt_add()
+#   - tdh_phymem_pamt_remove()
+#
+# In the current Dynamic PAMT implementation, each active Dynamic PAMT region
+# covers one 2MB-aligned host physical address range and uses two 4KB backing
+# pages. Therefore, the estimated Dynamic PAMT memory usage is calculated as:
+#
+#   Dynamic PAMT usage (KB)
+#     = (PAMT.ADD calls - PAMT.REMOVE calls) * 8
+#
+# where:
+#   - one tdh_phymem_pamt_add() call represents adding 8KB of Dynamic PAMT
+#     backing memory for a 2MB host physical memory region;
+#   - one tdh_phymem_pamt_remove() call represents releasing the corresponding
+#     8KB of Dynamic PAMT backing memory.
+#
+# The basic test flow is:
+#
+#   1. Enable the ftrace function profiler and start with a clean profiling
+#      window.
+#   2. Record the baseline Dynamic PAMT usage before creating the TDX guest.
+#   3. Create and boot a KVM TDX guest.
+#   4. Verify that Dynamic PAMT usage increases after the TDX guest is created
+#      and private memory is populated.
+#   5. Destroy the TDX guest and wait until the VM process exits completely.
+#   6. Verify that Dynamic PAMT usage returns to the original baseline,
+#      indicating that the Dynamic PAMT backing pages were reclaimed.
+#
+# This is intended as a lightweight functional check and as a replacement for
+# the previous /proc/meminfo TDX memory counter that was removed from the
+# Dynamic PAMT patch series in upstream.
+#
+# Note:
+#   The ftrace function profiler counts function invocations rather than the
+#   return status of the underlying TDH.PHYMEM.PAMT.ADD/REMOVE operations.
+#   Therefore, the calculation assumes the normal successful execution path.
+#   Dynamic PAMT-related kernel warnings or errors will be checked separately
+#   in dmesg and treated as test failures by dpamt_dmesg_check function.
