Pressing a button on a remote control unit will typically lead to messages being sent several times per second until the button is released. Some remote control units indicate long key presses by sending special "repeat" messages, for which the protocol driver calls rc_repeat(). Other units repeat the same message over and over, which will be handled by calling rc_keydown(). The function rc_keydown() never set the LIRC "repeat" flag to distinguish repeated messages that were sent due to a long keypress, and messages sent due to repeated short keypresses. While a user-space program may implement special logic to distinguish long keypresses, it is much simpler to be able to rely on the flag. Commit de142c32 ("media: lirc: implement reading scancode") would never set the LIRC_SCANCODE_FLAG_REPEAT flag. Commit b66218fd ("media: lirc: ensure lirc device receives nec repeats") fixed it up for rc_repeat() but not rc_keydown(). Signed-off-by:

Future additions to the ent_config[] could break the association between the index of the struct vimc_ent_config entries in the ent_config[] array, and the index defined by the enum proposed in the previous patch. Using designated initializers solves this by linking the 2 together clearly in code and prevents the array not reflecting the enum. There is no functional change intended. Suggested-by:

The data_links array was hard to read and understand. By implementing enumerated vimc data link entities, clarity has been improved when defining data_links. This therefore should help new programmers to understand the codebase better. There is no functional change intended. Suggested-by:

When introducing the lens controller, it became apparent that the vimc entity type names were hard to understand, e.g. vimc_len_type refers to the lens. The names of the vimc entity types have been expanded to make the code easier to understand. There is no functional change intended. Suggested-by:

For camera sensor devices the firmware information of which comes from non-DT (or some ACPI variants), the kernel makes the information visible to the drivers in a form similar to DT. This takes place through device's secondary fwnodes, in which case also the secondary fwnode needs to be heterogenously (endpoint vs. device) matched.

For format V4L2_PIX_FMT_VC1_ANNEX_L, the amphion vpu requires driver to help insert some custom startcode before sequence and frame. but only the first sequence startcode is needed, the extra startcode will cause decoding error. So after seek, we don't need to insert the sequence startcode. In other words, for V4L2_PIX_FMT_VC1_ANNEX_L, the vpu doesn't support dynamic resolution change.

Commit 1f82f2df ("media: hantro: Enable H.264 on Rockchip VDPU2") enabled H.264 on some SoCs with VDPU2 cores. This had the side-effect of exposing H.264 coded format as supported on RK3399.

Don't set last_buffer_dequeued during dynamic resolution change, otherwise it may be cleared in handling resolution change, as streamoff may be called in dynamic resolution change. Normally, this does not happen. But we encounter a special testcase, User issue V4L2_DEC_CMD_STOP after enqueue one buffer that only contains codec config header, but not any frame data. So VPU report the parsed resolution, then report the eos event. So driver should notify user to handle resolution change first, after it's handled, set the last_buffer_dequeued. then the user can exit decoding normally. Otherwise the user may be stalled.

The decoder parameters are stored in each instance's context data. This needs to be initialized per-instance, but a previous fix incorrectly changed it to only be initialized for the first opened instance. This resulted in subsequent instances not correctly signaling the requirement for the Requests API. Fix this by calling the initializing function outside of the v4l2_fh_is_singular() conditional block.

Right now the decoder maintains two separate lists for supported pixel formats and frame sizes. Getting the supported frame sizes for the current set format is a bit convoluted, requiring a search through the separate frame size list. The frame sizes are used to clamp and align requested resolutions. Instead, the frame size structure could be embedded inside the pixel format structure. Getting one also gets the other. And since the the driver already keeps pointers to the current set format, getting the frame sizes becomes straightforward. Do just that. Move v4l2_frmsize_stepwise inside mtk_video_fmt, and get rid of mtk_codec_framesizes. Signed-off-by:

After the previous patches: - media: mediatek: vcodec: decoder: Fix 4K frame size enumeration - media: mediatek: vcodec: decoder: Skip alignment for default resolution - media: mediatek: vcodec: decoder: Fix resolution clamping in TRY_FMT the max_{width,height} fields in |struct mtk_vcodec_ctx| no longer have any real users. Remove them. Fixes: b018be06 ("media: mediatek: vcodec: Read max resolution from dec_capability") Signed-off-by:

In commit b018be06 ("media: mediatek: vcodec: Read max resolution from dec_capability"), TRY_FMT clamps the resolution to the maximum that was previously set either by default 1080p or the limit set by a previous S_FMT call. This does not make sense when doing TRY_FMT for the output side, which may have different capabilities. Instead, for the output side, find the maximum resolution based on the pixel format requested. For the capture side, find the maximum resolution based on the currently set output format. The maximum resolution is found from the list of per-format frame sizes, so the patch "media: mediatek: vcodec: dec: Fix 4K frame size enumeration" is needed.

The default resolution of 64x64 is already aligned, according to the call to v4l_bound_align_image() in mtk_vcodec_dec_set_default_params(). Drop the redundant v4l_bound_align_image() call. This also removes one usage of ctx->max_{width,height}. Signed-off-by: -

This partially reverts commit b018be06 ("media: mediatek: vcodec: Read max resolution from dec_capability"). In this commit, the maximum resolution ended up being a function of both the firmware capability and the current set format. However, frame size enumeration for output (coded) formats should not depend on the format set, but should return supported resolutions for the format requested by userspace. Fix this so that the driver returns the supported resolutions correctly, even if the instance only has default settings, or if the output format is currently set to VP8F, which does not support 4K. This adds an copy of special casing for !VP8 and 4K support. The other existing copy will be removed when .max_{width,height} are removed from |struct mtk_vcodec_ctx| in a subsequent patch.
