This test is specific to MTE and verifies that the GCR_EL1 register is context switched correctly. It spawns 1024 processes and each process spawns 5 threads. Each thread writes a random setting of GCR_EL1 through the prctl() system call and reads it back verifying that it is the same. If the values are not the same it reports a failure. Note: The test has been extended to verify that even SYNC and ASYNC mode setting is preserved correctly over context switching.
