Below are the different buffer attributes: BUF_ATTR_DEFERRED - buffer queued by client but not submitted to firmware. BUF_ATTR_READ_ONLY - processed buffer received from firmware as read only. These buffers are held in firmware as reference for future frame processing. BUF_ATTR_PENDING_RELEASE - buffers requested to be released from firmware. BUF_ATTR_QUEUED - buffers submitted to firmware. BUF_ATTR_DEQUEUED - buffers received from firmware. BUF_ATTR_BUFFER_DONE - buffers sent back to vb2. Buffers are submitted and received via HFI_CMD_BUFFER. Firmware associates below flags during buffer response: HFI_BUF_FW_FLAG_RELEASE_DONE - buffer released in firmware. HFI_BUF_FW_FLAG_READONLY - buffer used as reference in firmware. Input buffers dequeued from firmware are sent directly to vb2. Output buffers if read only, are sent to vb2 and also maintained in read only list. If the same read only buffer is received form client, HFI_BUF_HOST_FLAG_READONLY is attached to the buffer and submitted to firmware. Once the buffer is received from firmware as non read only, it is removed from read only list.
