Overview
|
|
--------
|
|
|
|
The dma-buf-test-exporter is a simple exporter of dma_buf objects.
|
|
It has a private API to allocate and manipulate the buffers which are represented as dma_buf fds.
|
|
The private API allows:
|
|
* simple allocation of physically non-contiguous buffers
|
|
* simple allocation of physically contiguous buffers
|
|
* query kernel side API usage stats (number of attachments, number of mappings, mmaps)
|
|
* failure mode configuration (fail attach, mapping, mmap)
|
|
* kernel side memset of buffers
|
|
|
|
The buffers support all of the dma_buf API, including mmap.
|
|
|
|
It supports being compiled as a module both in-tree and out-of-tree.
