This series adds support for mt8192 h264/vp8/vp9 decoder drivers. Firstly, refactor power/clock/interrupt interfaces for mt8192 is lat and core architecture.
Secondly, add new functions to get frame buffer size and resolution according to decoder capability from scp side. Then add callback function to get/put capture buffer in order to enable lat and core decoder in parallel.
Then add to support MT21C compressed mode and fix v4l2-compliance fail.
Next, extract H264 request api driver to let mt8183 and mt8192 use the same code, and adds mt8192 frame based h264 driver for stateless decoder.
Lastly, add vp8 and vp9 stateless decoder drivers.
Patches 1 refactor power/clock/interrupt interface. Patches 2~4 get frame buffer size and resolution according to decoder capability. Patches 5~6 enable lat and core decode in parallel. Patch 7~10 add to support MT21C compressed mode and fix v4l2-compliance fail. patch 11 record capture queue format type. Patch 12~13 extract h264 driver and add mt8192 frame based driver for h264 decoder. Patch 14~15 add vp8 and vp9 stateless decoder drivers. --- changes compared with v6: - rebase to the latest media stage and fix conficts - fix memcpy to memcpy_fromio or memcpy_toio - fix h264 crash when test field bitstream changes compared with v5: - fix vp9 comments for patch 15 - fix vp8 comments for patch 14. - fix comments for patch 12. - fix build errors. changes compared with v4: - fix checkpatch.pl fail. - fix kernel-doc fail. - rebase to the latest media codec driver. changes compared with v3: - remove enum mtk_chip for patch 2. - add vp8 stateless decoder drivers for patch 14. - add vp9 stateless decoder drivers for patch 15. changes compared with v2: - add new patch 11 to record capture queue format type. - separate patch 4 according to tzung-bi's suggestion. - re-write commit message for patch 5 according to tzung-bi's suggestion. changes compared with v1: - rewrite commit message for patch 12. - rewrite cover-letter message. --- Yunfei Dong (15): media: mtk-vcodec: Add vdec enable/disable hardware helpers media: mtk-vcodec: Using firmware type to separate different firmware architecture media: mtk-vcodec: get capture queue buffer size from scp media: mtk-vcodec: Read max resolution from dec_capability media: mtk-vcodec: Call v4l2_m2m_set_dst_buffered() set capture buffer buffered media: mtk-vcodec: Refactor get and put capture buffer flow media: mtk-vcodec: Refactor supported vdec formats and framesizes media: mtk-vcodec: Add format to support MT21C media: mtk-vcodec: disable vp8 4K capability media: mtk-vcodec: Fix v4l2-compliance fail media: mtk-vcodec: record capture queue format type media: mtk-vcodec: Extract H264 common code media: mtk-vcodec: support stateless H.264 decoding for mt8192 media: mtk-vcodec: support stateless VP8 decoding media: mtk-vcodec: support stateless VP9 decoding

MT8173 platform use vpu firmware, mt8183/mt8192 will use scp firmware instead, using chip name is not reasonable to separate different firmware architecture. Using firmware type is much better.

Hi Yunfei,
this patch does not work unless userland calls enum_framesizes, which is completely optional. See comment and suggestion below.

The spec does not require calling enum_fmt, so changing the maximum here is incorrect (and fail with GStreamer). If userland never enum the framesizes, the resolution get limited to 1080p.
As this only depends and the OUTPUT format and the device being open() (condition being dev_capability being set and OUTPUT format being known / not VP8), you could initialize the cxt max inside s_fmt(OUTPUT) instead, which is a mandatory call. I have tested this change to verify this:

Recent testing on ChromeOS suggests this doesn't work. The spec implies that querying capabilities could happen before the output format is set. And also, supported frame sizes are detected for each given format, which may not be the one current set.

In v4l2, formats are always set. Perhaps the problem is that we don't automatically set ctx->max_width/height for the default format when the firmware is up. I noticed recently the chromium always do G_FMT before S_FMT, so perhaps it can skip S_FMT if the default format is appropriate, and that endup avoiding the code I've just suggested. At the time I wrote that, I only had GStreamer available to test, and it always calls S_FMT, which is mandatory, see 4.5.3.2. Initialization step 1. But I cannot say userland would be wrong to skip if that format was "initially" correct.
If my understanding is not correct, then perhaps you should provide a tad more details on how this failed for you, and we can then better judge an appropriate fix.

Lat and core work in different thread, setting capture buffer buffered.
... so that output queue buffers (bitstream) can be process regardless if there is available capture buffers.
I have concerns around the usefulness of running a dedicated thread to drive the lat and the core blocks. Having 3 threads (counting the m2m worker thread) here increase the complexity. The hardware is asynchronous by definition. I think this patch will go away after a proper rework of the driver thread model here.

This haven't changed since last version, so recording the problem with this patch again. The request is being completed here as soon as the lat job is done. This is too soon, here's what the spec says [1]:
User-space can poll() a request file descriptor in order to wait until the request completes. A request is considered complete once all its associated buffers are available for dequeuing and all the associated controls have been updated with the values at the time of completion. Note that user-space does not need to wait for the request to complete to dequeue its buffers: buffers that are available halfway through a request can be dequeued independently of the request’s state.
In short, the request can't be completed until the core has finished and the related capture buffer have been marked done. As a side effect, you need to handle completing the request in all the possible error cases (you might want to refactor this). Please sync with Benjamin, he's currently trying to find a way to simplify the threading model and the driver while at it. This will otherwise tend to be racy and hard to maintain.

Supported output and capture format types for mt8192 are different with mt8183. Needs to get format types according to decoder capability.
This patch is both refactoring and changing the behaviour. Can you please split the non-functional changes from the functional one. This ensure we can proceed with a good review of the functional changes.
I will split this patch. Thanks.
regards, Nicolas

This change is ok, but the commit message should be changed to advertise that this is preparation for the new stateless H264 decoding driver. Besides, I suggest to reorder the commits sequence, so that this commit goes in between "Extract H264 common code" and "support stateless H.264 decoding for mt8192", as this last one is the actual real user of this change.
Anyway, this is my commit message proposal:
The capture queue format type may be differ depending on platform: for stateless decoder drivers, we need to calculate the capture buffer size according to the capture queue format type in SCP.
As a preparation for introducing drivers for stateless decoding, save the current capture queue type on a per vcodec context basis.

Should use the stride (bytesperline) instead, this will allow un-hardcoding the width alignment. And normally, the alignnement should also be found/set in the fmt, so you could maybe use that only ?
Though, I'm not sure I understand why single plane is supported here. MM21 seems to be defined with 2 planes and there is no other formats.

Thanks for this work.
Le mercredi 23 février 2022 à 11:40 +0800, Yunfei Dong a écrit :
Add support for VP8 decoding using the stateless API, as supported by MT8192.
With the struct members naming made consistent, even though I would like your patch better if it was not duplicating so much code, I'll give you my:

There is clearly room for improvement, this is line by line identical to the H.264 code. There is a lot in this file that looks like copy-paste with minor edits. Probably not a road block, but it would be really nice to try and clean these by making the common code common to avoid load of copy paste, which may lead to having to fix bugs in multiple places.

/** * vdec_if_init() - initialize decode driver
Le mercredi 23 février 2022 à 11:40 +0800, Yunfei Dong a écrit :
Add support for VP9 decoding using the stateless API, as supported by MT8192. And the drivers is lat and core architecture.
You already have a reviewed tag, but I'm under the impression that there is a fair amount of duplication with the helper library v4l2-vp9:
include/media/v4l2-vp9.h drivers/media/v4l2-core/v4l2-vp9.c
Can you at least give it a look and comment on why you can't use/adapt it for this driver ?
