| D | README | 3 File: ion_test.sh : Utility to test ION driver buffer sharing mechanism.
8 This is a test utility to verify ION buffer sharing in user space
11 another process to share the same buffer.
12 This utility demonstrates how ION buffer sharing can be implemented between
24 The server part (ionapp_export) is the exporter of the buffer.
25 It is responsible for creating an ION client, allocating the buffer based on
26 the heap id, writing some data to this buffer and then exporting the FD
27 (associated with this buffer) to another process using socket IPC.
28 This FD is called as buffer FD (which is different than the ION client FD).
30 The client part (ionapp_import) is the importer of the buffer.
