+# Queueless Trusty IPC
+
+ql-tipc is a portable client library that implements Trusty queueless IPC.
+It is intended to enable Trusty IPC in bootloader environments.
+
+## Code organization
+
+### IPC components
+
+- libtipc - Functions to be called by library user
+- ipc - IPC library
+- ipc_dev - Helper functions for sending requests to the secure OS
+- rpmb_proxy - Handles RPMB requests from secure storage service
+- avb - Sends requests to the Android Verified Boot service
+
+### Misc
+
+- examples/ - Implementations of bootloader-specific code.
+- arch/$ARCH/ - Architecture dependent implementation of Trusty device
+   (see trusty_dev.h). Implements SMCs on ARM for example.
+
+## Portability Notes
+
+The suggested approach to porting ql-tipc is to copy all header and C files
+into the bootloader and integrate as needed. RPMB storage operations and
+functions defined in trusty/sysdeps.h require system dependent implementations.
+
+If the TIPC_ENABLE_DEBUG preprocessor symbol is set, the code will include
+debug information and run-time checks. Production builds should not use this.
