2 | * @brief Check how rtems_bdbuf_sync() works. |
---|
3 | * |
---|
4 | * Test sequence: |
---|
5 | * -# Call rtems_bdbuf_read(#N) in thread #1. |
---|
6 | * -# Call rtems_bdbuf_sync(#N) in thread #1. |
---|
7 | * -# After a while disk driver gets write request for block #N. |
---|
8 | * Notify bdbuf about write complete event. |
---|
9 | * -# Check that rtems_bdbuf_sync(#N) in thread #1 unlocked after this. |
---|
10 | * -# Call rtems_bdbuf_read(#N) in thread #2. |
---|
11 | * -# Check that buffer is successfully obtained in thread #2. |
---|
12 | * -# Call rtems_bdbuf_release(#N) in thread #2. |
