media: iris: Add internal buffer calculation for AV1 decoder

2026-01-14T07:25:55+00:00

Implement internal buffer count and size calculations for AV1 decoder for all the buffer types required by the AV1 decoder, including BIN, COMV, PERSIST, LINE, and PARTIAL. This ensures the hardware decoder has properly allocated memory for AV1 decoding operations, enabling correct AV1 video playback.

media: iris: Allocate and queue internal buffers for encoder video device

2025-09-10T07:02:45+00:00

Add support for allocating and queuing internal buffers required by the encoder. The sizes of these buffers are derived from hardware specifications and are essential to meet the encoder's functional and performance requirements. These buffers are not exposed to userspace; they are allocated and managed internally to ensure correct and efficient hardware operation.

media: iris: Fix port streaming handling

2025-09-10T07:02:31+00:00

The previous check to block capture port streaming before output port was incorrect and caused some valid usecase to fail. While removing that check allows capture port to enter streaming independently, it also introduced firmware errors due to premature queuing of DPB buffers before the firmware session was fully started which happens only when streamon is called on output port. Fix this by deferring DPB buffer queuing to the firmware until both capture and output are streaming and state is 'STREAMING'.

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.
