+=========================
+Encryption IDs Controller
+=========================
+
+Overview
+========
+There are multiple hardware memory encryption capabilities provided by the
+hardware vendors, like Secure Encrypted Virtualization (SEV) and SEV Encrypted
+State (SEV-ES) from AMD.
+
+These features are being used in encrypting virtual machines (VMs) and user
+space programs. However, only a small number of keys/IDs can be used
+simultaneously.
+
+This limited availability of these IDs requires system admin to optimize
+allocation, control, and track the usage of the resources in the cloud
+infrastructure. This resource also needs to be protected from getting exhausted
+by some malicious program and causing starvation for other programs.
+
+Encryption IDs controller provides capability to register the resource for
+controlling and tracking through the cgroups.
+
+How to Enable Controller
+========================
+
+- Enable Encryption controller::
+
+        CONFIG_CGROUP_ENCRYPTION_IDS=y
+
+- Above options will build Encryption controller support in the kernel.
+  To mount the Encryption controller::
+
+        mount -t cgroup -o encryption none /sys/fs/cgroup/encryption
+
+
+Interface Files
+===============
+Each encryption ID type have their own interface files,
+encryption_id.[ID TYPE].{max, current, stat}, where "ID TYPE" can be sev and
+sev-es.
+
+  encryption_ids.[ID TYPE].stat
+        A read-only flat-keyed single value file. This file exists only in the
+        root cgroup.
+
+        It shows the total number of encryption IDs available and currently in
+        use on the platform::
+          # cat encryption.sev.stat
+          total 509
+          used 0
+
+  encryption_ids.[ID TYPE].max
+        A read-write file which exists on the non-root cgroups. File is used to
+        set maximum count of "[ID TYPE]" which can be used in the cgroup.
+
+        Limit can be set to max by::
+          # echo max > encryption.sev.max
+
+        Limit can be set by::
+          # echo 100 > encryption.sev.max
+
+        This file shows the max limit of the encryption ID in the cgroup::
+          # cat encryption.sev.max
+          max
+
+        OR::
+          # cat encryption.sev.max
+          100
+
+        Limits can be set more than the "total" capacity value in the
+        encryption_ids.[ID TYPE].stat file, however, the controller ensures
+        that the usage never exceeds the "total" and the max limit.
+
+  encryption_ids.[ID TYPE].current
+        A read-only single value file which exists on non-root cgroups.
+
+        Shows the total number of encrypted IDs being used in the cgroup.
+
+Hierarchy
+=========
+
+Encryption IDs controller supports hierarchical accounting. It supports
+following features:
+
+1. Current usage in the cgroup shows IDs used in the cgroup and its descendent cgroups.
+2. Current usage can never exceed the corresponding max limit set in the cgroup
+   and its ancestor's chain up to the root.
+
+Suppose the following example hierarchy::
+
+                        root
+                        /  \
+                       A    B
+                       |
+                       C
+
+1. A will show the count of IDs used in A and C.
+2. C's current IDs usage may not exceed any of the max limits set in C, A, or
+   root.
+
+Migration and ownership
+=======================
+
+An encryption ID is charged to the cgroup in which it is used first, and
+stays charged to that cgroup until that ID is freed. Migrating a process
+to a different cgroup do not move the charge to the destination cgroup
+where the process has moved.
