Parameter Transfer of the Shared Memory in the Secure OS

4.2.9-1

Verify that the parameters of the shared memory in the secure OS can be transferred.

See Test Networking.

1. The TrustZone kit has been burnt into the server and the TrustZone license has been activated.
2. The REE patch has been loaded to the server. The CA and TA can be loaded and can communicate with each other properly.

1. Log in to the REE OS and load the TrustZone REE patch tzdriver. (See Expected Result 1.)

   insmod tzdriver

   /usr/bin/teecd &

2. Write the CA and TA and make the following requirements on the CA and TA code. (See Expected Result 2.)

   The CA transfers parameters by using TEEC_AllocateSharedMemory and TEEC_RegisterSharedMemory.

1. The REE patch is loaded and no error information is displayed.
2. The APIs are working properly and the TA can access the parameter information transferred by the CA.

4.2.9-2

Verify that the parameters of the zero-copy shared memory in the secure OS can be transferred.

See Test Networking.

1. The TrustZone kit has been burnt into the server and the TrustZone license has been activated.
2. The REE patch has been loaded to the server. The CA and TA can be loaded and can communicate with each other properly.

1. Log in to the REE OS and load the TrustZone REE patch tzdriver. (See Expected Result 1.)

   insmod tzdriver

   /usr/bin/teecd &

2. Write the CA and TA and make the following requirements on the CA and TA code. (See Expected Result 2.)
   • The CA applies for zero-copy shared memory through TEEC_AllocateSharedMemory.
   • The CA transfers parameters to the TA through the zero-copy shared memory.

1. The REE patch is loaded and no error information is displayed.
2. The APIs are working properly and the TA can access the parameter information transferred by the CA.
