-// This file is a snapshot of an AIDL file. Do not edit it manually. There are
-// two cases:
-// 1). this is a frozen version file - do not edit this in any case.
-// 2). this is a 'current' file. If you make a backwards compatible change to
-//     the interface (from the latest frozen version), the build system will
-//     prompt you to update this file with `m <name>-update-api`.
-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

-// This file is a snapshot of an AIDL file. Do not edit it manually. There are
-// two cases:
-// 1). this is a frozen version file - do not edit this in any case.
-// 2). this is a 'current' file. If you make a backwards compatible change to
-//     the interface (from the latest frozen version), the build system will
-//     prompt you to update this file with `m <name>-update-api`.
-//
-// You must not make a backward incompatible change to any AIDL file built
-// with the aidl_interface module type with versions property set. The module
-// type is used to build AIDL files in a way that they can be used across
-// independently updatable components of the system. If a device is shipped
-// with such a backward incompatible change, it has a high risk of breaking
-// later when a module using the interface is updated, e.g., Mainline modules.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+# DRM HAL
+
+This is the underlying HAL implementation for `MediaDrm`/`MediaCrypto` (and
+their NDK counterparts).
+
+## Plugin-vendor-specific VTS modules
+
+The interface `DrmHalVTSVendorModule_V1` is compatible with all versions of the
+DRM HAL (hidl 1.0-1.4, aidl).
+
+Please see `./1.0/vts/doc/Drm_Vendor_Modules_v1.pdf`.
+
+TODO(b/266091099): convert `Drm_Vendor_Modules_v1.pdf` to Markdown.

 We believe that Curve25519 offers the best tradeoff in terms of security,
 efficiency and global trustworthiness, and that it is now sufficiently
 widely-used and widely-implemented to make it a practical choice.
 
-However, since Secure Elements (SE) do not currently offer support for curve
-25519, we are allowing implementations to instead make use of EC P-256 for
-signing and ECDH. To put it simply, the device unique key pair will be a P-256
-key pair for ECDSA instead of Ed25519, and the ProtectedData COSE\_Encrypt
-message will have its payload encrypted with P-256 ECDH key exchange instead of
-X25519.

 The CDDL in the rest of the document will use the '/' operator to show areas
