media: iris: Fix memory leak by freeing untracked persist buffer

2025-10-06T09:18:48Z

commit 02a24f13b3a1d9da9f3de56aa5fdb7cc1fe167a2 upstream. One internal buffer which is allocated only once per session was not being freed during session close because it was not being tracked as part of internal buffer list which resulted in a memory leak. Add the necessary logic to explicitly free the untracked internal buffer during session close to ensure all allocated memory is released properly.

media: iris: Skip destroying internal buffer if not dequeued

2025-08-28T14:34:29Z

commit 7c452ffda30c0460c568273993a3d3c611486467 upstream. Firmware might hold the DPB buffers for reference in case of sequence change, so skip destroying buffers for which QUEUED flag is not removed.

2025-02-07T10:51:45Z

Implement the vb2 ops for the buf queue. These are the different buffer attributes: BUF_ATTR_DEFERRED - buffer queued by the client but not submitted to firmware. BUF_ATTR_PENDING_RELEASE - buffers requested to be released from the firmware. BUF_ATTR_QUEUED - buffers submitted to the firmware. BUF_ATTR_DEQUEUED - buffers received from the firmware. BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.
