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
12 This utility demonstrates how ION buffer sharing can be implemented between
14 The following heap types are supported by ION driver.
25 It is responsible for creating an ION client, allocating the buffer based on
28 This FD is called as buffer FD (which is different than the ION client FD).
38 ION driver and only one time allocation.
42 This utility works only if /dev/ion interface is present.
43 The following configs needs to be enabled in kernel to include ion driver.
